[0028] Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings.

[0029] This embodiment is for ventilating a space to be ventilated. Ventilation may be exhaust of the space to be ventilated or intake of air into the space to be ventilated, but it is preferable that both exhaust and intake are possible. Below, a tent (including a shelter) is mainly exemplified as a space to be ventilated.

[0030] (First embodiment) 1A and 1B are respectively a side view and a front view of the ventilation device 100. Also, FIG. 1C is a side view showing the ventilation device 100 in use. The ventilation device 100 comprises a main body 1, a lid 2, and a ventilation member 3. These may be integrated, but it is preferable that they are separable as separate parts for ease of portability and storage.

[0031] 1C , the space to be ventilated 200 is separated from the outside 202 by an awning 201, such as a fly sheet or skirt of a tent. When the ventilation device 100 is in use, the ventilation member 3 is sandwiched between the awning 201 and the ground. As a result, the main body 1, the lid 2, and a part of the ventilation member 3 are disposed inside the space to be ventilated 200, and the other part (the tip side) of the ventilation member 3 is disposed outside the space to be ventilated 200.

[0032] Main unit 1 2A to 2C are, respectively, a transparent side view, a transparent front view, and a transparent rear view of main body 1. Main body 1 has a casing 11, a fan mounting member 12, and a power supply mounting member .

[0033] The casing 11 has a front surface 111 and a back surface 112 facing each other, and two side surfaces 113 connecting the front surface 111 and the back surface 112. The casing 11 may have a bottom surface. The top of the casing 11 is open, and the lid 2 can be attached and detached. The material of the casing 11 is, for example, plastic, and polyethylene, which has excellent physical properties such as strength, hardness, and impact resistance, is particularly suitable.

[0034] During use, the front surface 111 is covered by a awning 201 that separates the space to be ventilated 200 from the outside 202 (see FIG. 1C). A ventilation hole 111a is formed in the lower part of the front surface 111. A ventilation member connection part 114 is provided so as to protrude from the front surface 111 toward the space to be ventilated 200 (the opposite side to the back surface 112) and communicates with the ventilation hole 111a. A fitting protrusion 114a is formed in the ventilation member connection part 114, allowing the ventilation member 3 to be attached to and detached from the casing 11.

[0035] An air vent 112a is formed in the upper part of the rear surface 112. The air flow generated by the fan 4, which will be described later, passes through the air vent 112a. It is preferable that a filter 112b is provided at a position corresponding to the air vent 112a on the rear surface 112 to prevent insects such as mosquitoes from entering the space 200 to be ventilated.

[0036] The side surface 113 has a structure to which legs 115 for supporting the casing 11 can be attached. The legs 115 are fixed to the ground, for example, by pegs. Alternatively, the lower parts of the legs 115 may be embedded in the ground to fix them (however, the ventilation openings 111a on the front surface 111 must be above ground).

[0037] Here, the front surface 111 and the rear surface 112 may be upright, but are preferably inclined as shown in the figure. In detail, at least the front surface 111 is inclined with respect to the vertical plane in a direction away from the ventilation member connection portion 114 as it approaches the upper portion. In other words, the angle α between the front surface 111 and the ground between the front surface 111 and the rear surface 112 and the front surface 111 is less than 90 degrees, for example, about 45 to 85 degrees. This angle may be adjustable. In many cases, the awning 201 such as a fly sheet or a skirt is dome-shaped with the lower portion expanding outward, and the inclination of the front surface 111 reduces interference with the dome-shaped awning 201.

[0038] Lighting may be added at any position of the casing 11 to provide indirect lighting for the space 200 to be ventilated.

[0039] The fan mounting member 12 is provided between the front surface 111 and the rear surface 112, and defines a location for mounting the fan 4. In detail, the fan mounting member 12 is provided so that the fan 4 is fixed at a position facing the ventilation hole 112a formed in the rear surface 112. As a specific example, the fan mounting member 12 has a pair of convex rails 121 attached to two side surfaces 113. By inserting the fan 4 into the convex rails 121 through an opening in the upper part of the casing 11, the fan 4 is supported and fixed by the lower part of the convex rails 121 and the rear surface 112.

[0040] The air flow generated by the fan 4 has a directionality according to the rotation direction of the fan 4. Therefore, when the fan 4 is installed on the fan installation member 12 in a certain direction, air can be drawn in from the space to be ventilated 200 (i.e., the ventilation device 100 can be used as an intake device). When the fan 4 is installed on the fan installation member 12 in the opposite direction, air can be exhausted from the space to be ventilated 200 (i.e., the ventilation device 100 can be used as an exhaust device). By configuring the fan installation member 12 with a convex rail 121, the fan 4 can be easily inserted and its direction can be easily changed even when the ventilation device 100 is installed on the ground (fixed with pegs, etc.). The fan 4 may be capable of mechanically switching the air flow.

[0041] The fan 4 may be included in the ventilation device 100 or may be a separate member. For example, a 12 cm or 14 cm large diameter DC motor fan for PCs is suitable as the fan 4, which is quiet, has high gas flow efficiency, is easy to obtain, is inexpensive, and has stable quality. The number of fans 4 to be installed is also arbitrary, and for example, about four small diameter (7 cm) fans 4 may be installed. In general, the smaller the diameter of the fan 4, the lower the power consumption and noise. On the other hand, the larger the diameter of the fan 4, the stronger the wind force. These factors should be considered and an optimal fan 4 should be installed. In addition, a remote control circuit unit may be incorporated in the fan 4 so that the power can be turned on and off, the rotation speed can be controlled by remote control. Furthermore, the motor that drives the fan 4 may be a DC motor or an AC motor.

[0042] Here, it is desirable to provide the fan mounting member 12 at a somewhat high position so that the fan 4 does not get wet and break down even if puddles form on the ground due to rain or the like. Specifically, it is desirable to provide the fan mounting member 12 so that the horizontal plane including the rotation center of the fan 4 is at a position higher than the horizontal plane including the upper end of the ventilation member 3 (or the upper end of the ventilation opening 111a). It is even more desirable to provide the fan mounting member 12 so that the horizontal plane including the lower end of the fan 4 is at a position higher than the horizontal plane including the upper end of the ventilation member 3 (or the upper end of the ventilation opening 111a). For example, the lower end of the fan 4 is 100 mm or more from the bottom surface of the case fitting 11.

[0043] The power supply mounting member 13 is provided between the front surface 111 and the rear surface 112, and defines a place for mounting the power supply for the fan 4. As a specific example, the power supply mounting member 13 is composed of a pair of convex rails 131 attached to the two side surfaces 113, and a partition plate 132. By inserting the partition plate 132 into the convex rails 131 through an opening in the upper part of the casing 11, a space is created in which to place the power supply.

[0044] The power supply is installed in a space surrounded on all sides by the partition plate 132, the front surface 111, the back surface 112 and the side surfaces 113 of the casing 11, and the lid 2, and the power supply can be protected from external shocks. The power supply is stored in a plastic bag in the power supply installation space, which further improves water resistance and shock resistance.

[0045] The power supply may be provided in the ventilation device 100 or may be a separate member. There are no particular limitations on the size of the power supply as long as it fits into the space defined by the power supply installation member 13, but for example, it may be a rechargeable USB battery that supplies power to the fan 4 via a USB cable. A fan speed controller or an on-off controller may be provided between the fan 4 and the power supply.

[0046] Here, it is preferable to configure the air so that when exhausting or suctioning air, the air hits the power supply installation member 13 (the partition plate 132 of the power supply installation member 13). This allows the power supply installed in the power supply installation member 13 to be cooled.

[0047] lid 2 3A to 3C are a side view, a front view, and a rear view of the lid 2, respectively.

[0048] The lid 2 has a front surface 21 and a back surface 22 facing each other, two side surfaces 23 connecting the front surface 21 and the back surface 22, and a top surface 24, but the bottom is open. When the front surface 111 and the back surface 112 of the casing 11 are inclined, it is desirable that the front surface 21 and the back surface 22 of the lid 2 are also inclined accordingly. The lid 2 is used so that the opening at the bottom of the lid 2 covers the top of the casing 11. In detail, the lid 2 covers the casing 11 so that the front surface 21, the back surface 22, and the side surface 23 of the lid 2 are located outside the top of the front surface 111, the back surface 112, and the side surface 113 of the casing 11, respectively. This makes it possible to prevent rain from entering the casing 11 through the opening at the top of the casing 11 and wetting the fan 4 and the power supply arranged in the casing 11.

[0049] The lid 2 also has an eaves structure 25. The eaves structure 25 is U-shaped (C-shaped) and has a horizontal portion 251 attached to the rear surface 22 and an inclined portion 252 attached to the side surface 23. The inclined portion 252 inclines downward from the rear surface 22 toward the front surface 21. The eaves structure 25 is not provided on the front surface 21. By providing such an eaves structure 25, it is possible to prevent rain from entering the casing 11 through the ventilation hole 112a formed in the rear surface 112 of the casing 11, which would cause the fan 4 to break down.

[0050] Ventilation material 3 As shown in FIG. 1C, the ventilation member 3 is installed so as to face the front surface 111 of the casing 11 toward the space 200 to be ventilated, and forms an air passage between the fan 4 installed in the casing 11 and the space 200 to be ventilated.

[0051] 4A and 4B are a side view and a front view, respectively, of the ventilation member 3. As an example, the ventilation member 3 has an inner air passage 31, a filter portion 32, and an outer air passage 33. The inner end of the inner air passage 31 is connected to the front surface 111 of the casing 11, and the outer end is connected to the inner end of the filter portion 32. The outer end of the filter portion 32 is connected to the inner end of the outer air passage 33. The outer end of the outer air passage 33 is open toward the outside.

[0052] The inner air passage 31 is hollow (for example, cylindrical), and has an L-shaped fitting recess 31a formed in a part thereof. The fitting protrusion 114a of the ventilation member connection part 114 of the casing 11 fits into the fitting recess 31a of the inner air passage 31 of the ventilation member 3, thereby connecting the ventilation member 3 to the casing 11. When connected, the inner air passage 31 of the ventilation member 3 communicates with the ventilation port 111a formed in the front surface 111 of the casing 11 via the ventilation member connection part 114.

[0053] The filter part 32 is preferably made of a material that allows air to pass through but does not allow small insects (e.g., mosquitoes) to pass through, for example, a sponge material. This makes it possible to prevent insects from entering the ventilated space 200 from the outside 202 even when the ventilation device 100 is not in operation. In addition, the filter part 32 is preferably removable and washable.

[0054] The filter section 32 may be cylindrical, but preferably has a constricted section 32a (including a groove-shaped or concave one). As shown in Fig. 1C, this is because it is easy to align and cover the constricted section 32a with an awning 201 such as a fly sheet or skirt, and to fasten the awning 201 and the filter section 32 with a rubber band or string. Usually, the fly sheet or skirt is free to be attached to the ground, but by fixing it to the filter section 32 of the ventilation device 100, a reinforcing effect against wind is also achieved.

[0055] Furthermore, when the awning 201 is placed over the filter section 32, it is desirable that no gaps are formed between them. If there are gaps, insects will enter the ventilated space 200 from the outside 202. To achieve this, for example, in a vertical cross section near the narrowed section 32a of the filter section 32, the angle β between the tangent at the lower end (the part that comes into contact with the ground) and the ground on the filter section 32 side is preferably 90 degrees or less, and is, for example, shaped like a fish cake or a semicircle.

[0056] The outer ventilation passage 33 has an opening 33a that opens outward. This opening 33a is preferably inclined downward so that rain and insects are less likely to enter. The vertical cross section of the outer ventilation passage 33 is, for example, a triangle with its apex located upward (see FIG. 4B). Lighting may be added near the outer ventilation passage 33 to improve safety and crime prevention at night.

[0057] The configuration of the ventilation member 3 is not limited to the above. It may be configured with any number, shape and size of ventilation passages, and the amount and direction of the flowing air may be adjusted as appropriate. For example, a bellows hose may be incorporated between the inner ventilation passage 31 and the main body 1 to enable flexible installation. The ventilation member 3 is preferably provided with a constricted portion 32a to which the awning 201 is aligned. In addition, at the position of the ventilation member 3 where the awning 201 is aligned, the angle β between the tangent at the lower end of the vertical cross section of the outer hull of the ventilation member 3 and the ground on the ventilation member 3 side is preferably 90 degrees or less.

[0058] Use as an exhaust system 5 is a perspective side view of the ventilation device 100 when used as an exhaust device, with the air flow also shown. The fan 4 is installed in a predetermined direction so that air in the space 200 to be ventilated is taken into the casing 11 through the ventilation port 112a on the back surface 112. The air taken into the casing 11 from the fan 4 hits the power supply installation member 13 (the partition plate 132 of the power supply installation member 13). This cools the power supply installed in the power supply installation member 13. The air that hits the power supply installation member 13 is rectified and guided to the ventilation port 111a on the front surface 111. This air is exhausted to the outside 202 through the ventilation member 3.

[0059] Use as an intake device 6 is a perspective side view of the ventilation device 100 when used as an intake device, with the air flow also shown. The fan 4 is installed in a predetermined direction so that air from the outside 202 is taken into the casing 11 through the ventilation member 3 and the ventilation opening 111a on the front surface 111. This direction is opposite to that in the case of FIG. 5. The air from the outside 202 taken into the casing 11 hits the power supply installation member 13 (the partition plate 132 thereof). This cools the power supply installed in the power supply installation member 13. The air that hits the power supply installation member 13 is rectified and taken into the ventilated space 200 through the ventilation opening 112a on the back surface 112.

[0060] The above-described ventilation device 100 can be added to an existing tent and can ventilate the space to be ventilated 200. Therefore, there is no need to modify the tent, which is economical.

[0061] Second embodiment The ventilation device 100 according to the first embodiment can be used both as an exhaust device and as an intake device, but the second embodiment described below can also be used as an evaporative cooling device. Below, explanations of the points in common with the first embodiment will be omitted or simplified, and the ventilation member 3, which is the difference, will be mainly described.

[0062] 7 is a side view of the ventilation member 3. This ventilation member 3 has a cooling mechanism 35 that cools the air passing through the ventilation member 3. As an example, the cooling mechanism 35 has a cooling tool 351 that can contain a cooling medium, and a cooling medium supply member 352 that supplies the cooling medium to the cooling tool 351. The cooling medium is a liquid such as water.

[0063] The cooling device 351 can be configured with the filter portion 32 in the ventilation member 3 of the first embodiment (particularly shown in Figs. 4A and 4B). In this case, the cooling device 351 (filter portion 32) is made of a polyurethane or polyester sponge material (particularly open-cell type polyurethane foam is preferable), and it is desirable that the surface area in contact with the air passing through the ventilation member 3 is large. The cooling device 351 is disposed in the ventilation path in the ventilation member 3 so that the air passing through the ventilation member 3 comes into contact with the cooling medium. The cooling device 351 can also prevent the intrusion of insects such as mosquitoes.

[0064] The cooling medium supply member 352 may be a tray provided below the cooling tool 351, in which a cooling medium is placed. A part of the cooling tool 351 is immersed in the cooling medium, and the cooling medium supplied from the cooling medium supply member 352 is contained in the cooling tool 351.

[0065] Also, when the cooling medium contains water, the cooling tool 351 may have a cooling tool main body and a water-absorbing member. As described above, the cooling tool main body is preferably made of a polyurethane or polyester sponge material, which has a large surface area that comes into contact with air. On the other hand, such materials do not necessarily have good water absorption. Therefore, the cooling tool 351 is constructed by combining a water-absorbing member that has good water absorption and water retention, such as cotton, PVA, or cellulose, with the cooling tool main body. As an example, at least a part of the water-absorbing member is embedded in the cooling tool main body. Another part of the water-absorbing member is arranged so as to come into contact with the water contained in the cooling medium supply member 352. This allows the water-absorbing member to efficiently absorb water, and the cooling tool main body to contain water.

[0066] Fig. 8 is a perspective side view of ventilation device 100 when used as an evaporative cool air device. Although the air flow is also shown, it is almost the same as when used as an intake device shown in Fig. 6. When using ventilation device 100 as an evaporative cool air device, cooling medium such as water (and ice, if necessary) is also placed in cooling medium supply member 352. It is desirable to soak cooling tool 351 itself in water.

[0067] When air from the outside 202 passes through the ventilation member 3, the air is cooled by the cooling mechanism 35. In detail, when the air passing through the ventilation path of the ventilation member 3 comes into contact with the cooling medium and the cooling medium is evaporated, heat is removed from the air, and the air is cooled. The cooled air is taken into the ventilated space 200 through the ventilation opening 111a on the front surface 111 of the casing 11.

[0068] As described above, the ventilation device 100 according to the second embodiment can take in cooled air into the space 200 to be ventilated.

[0069] Some examples of use of the above-described ventilation device 100 will be given below.

[0070] 9 is a top view showing a schematic example of the positional relationship between the ventilation device 100 and a tent. This tent is a typical tent for 2 to 4 people, and is intended to use one ventilation device 100. The ventilation member 3 of the ventilation device 100 is passed under the fly sheet, and the fly sheet is fixed to the constricted portion 32a of the ventilation member 3.

[0071] The temperature inside the inner tent is affected by the temperature inside the fly sheet. The fly sheet is exposed to direct sunlight. Therefore, it is preferable to use the present ventilation device 100 as an exhaust device to improve ventilation inside the fly sheet and suppress the temperature rise inside the inner tent. Alternatively, if the inside of the tent is well ventilated and water can be prepared as a cooling medium, it is also effective to use the ventilation device 100 as an evaporative cooling device from the windward side.

[0072] 10 is a top view showing a schematic example of the positional relationship between the ventilation devices 100 and the tent. This tent is a typical tent for 2 to 4 people, and is intended to be used with two ventilation devices 100A, 100B arranged diagonally.

[0073] Depending on the surrounding environment, the following use cases are possible: (1) Ventilation device 100A: exhaust device, ventilation device 100B: intake device (2) Ventilation device 100A: exhaust device, Ventilation device 100B: exhaust device (3) Ventilation device 100A: Intake device, Ventilation device 100B: Intake device In the above case of (1), by using the ventilation device 100B used as the intake device as an evaporative cooling device, the temperature inside the tent can be lowered more effectively.

[0074] 11 is a top view diagrammatically illustrating another example of the positional relationship between the ventilation devices 100 and the tent. This tent is a typical two-room tent for six people, and is designed to use six ventilation devices 100A-100F. Each of the ventilation devices 100A-100F can be used flexibly according to the surrounding environment.

[0075] FIG. 12 is a top view showing another example of the positional relationship between the ventilation device 100 and the tent. This tent is a typical shelter for 2 to 4 people, and is assumed to use four ventilation devices 100A to 100D. The inner tent of the shelter has no floor and is entirely on the ground. Therefore, it is often used for winter camping, etc. When using a heating device or cooking inside the shelter, there is a risk of carbon monoxide poisoning or oxygen deficiency. Therefore, by using the ventilation devices 100A to 100D as intake devices, fresh outside air can be continuously taken in, thereby strengthening the risk hedge.

[0076] The ventilation device 100 is particularly suitable for single-wall tents that have no floor, as well as double-wall tents that have a floor (including tents where only the vestibule is double-walled) and tents that have a flysheet that reaches the ground and has installation space for the vestibule.
