Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ventilation hole provided in a structure such as a building and used for ventilation, ventilation, and the like.
[0002]
[Prior art]
BACKGROUND ART Buildings such as ordinary houses, buildings, condominiums, subways, underground malls and the like are provided with ventilation holes in a broad sense including ventilation holes for the purpose of ventilation with the outside. A louver and a shutter are provided in the opening to prevent rainwater from entering, and birds and insects from entering, and a vent that opens and closes the louver and the like by a method of pushing, pulling out, or turning is usually used. .
[0003]
In addition, there is also a product in which sound insulation is slightly considered by bending the open side of the outside air. Some have electric fans. It is usually a ventilation fan and an exhaust fan for the purpose of ventilation.
[0004]
Furthermore, a heat exchange type ventilation fan for indoor ventilation and suppression of heat loss is also known.
[0005]
[Problems to be solved by the invention]
As described above, vents having various configurations are known, but vents having a conventional configuration focus on only so-called ventilation functions such as ventilation and ventilation (air supply and exhaust), and are configured as simple through holes. I have.
[0006]
However, such a vent is also an opening through which external sounds and light enter the room. Until now, little attention has been paid to sound insulation since no attention has been paid to the formation of vent holes. The same applies to the light-shielding property.
[0007]
Therefore, the present inventor has considered that it is necessary to develop a technology that takes such points into consideration while securing the ventilation function. As described above, a ventilation fan provided with a heat exchange function in addition to the ventilation function is also known in the conventional configuration. However, such a configuration has a problem that it is large and cannot be applied to a ventilation hole of a normal size.
[0008]
In addition, a configuration that can be applied to a conventionally used vent having a diameter of, for example, about 150 φ is also preferable for exerting other functions while ensuring the ventilation function. Therefore, the present inventor thought that, instead of providing a configuration for exhibiting such a function outside of the ventilation hole, it could be configured in a ventilation hole that was conventionally configured simply as a ventilation hole. .
[0009]
If such a configuration can be provided inside the ventilation hole, the size of the ventilation hole itself can be kept at the conventional size, and no new problems such as installation place selection and construction labor will occur, and it will be suitable for on-site It seems easy to plan.
[0010]
Further, in the conventional configuration, when the forced air supply / exhaust means such as a fan is not provided, the wind direction, the temperature difference, the pressure difference, and the like are not sufficiently considered, and there are cases where the ventilation amount is almost left alone. In such a case, ventilation may not be ensured at all depending on conditions such as outside air.
[0011]
On the other hand, in the case of a ventilation fan equipped with a conventional fan, the size of the fan is too large to be used for ordinary ventilation holes, and about 150φ is not found. The point was also pointed out.
[0012]
The inventor of the present invention needs to enhance the other functions in addition to securing the ventilation function, and also develop a ventilation hole with a fan that can be applied to a ventilation hole size of about 150φ which does not require special consideration for the installation position. I thought.
[0013]
An object of the present invention is to make it possible to exert both the ventilation function and the function other than the ventilation function in the ventilation hole by devising the inside of the ventilation hole.
[0014]
It is another object of the present invention to provide a fan-equipped ventilation hole which is not restricted by an installation position in consideration of electric wiring and the like.
[0015]
[Means for Solving the Problems]
The present inventor has conceived of using the inside of the ventilation hole as a configuration in which the ventilation hole has both the ventilation function and the function other than the ventilation function.
[0016]
That is, the present invention is a ventilation hole that is provided so as to penetrate a partition member such as a wall, and ventilates both spaces separated by the partition member, wherein the ventilation hole extends along a ventilation direction in the hole. A plurality of air passages are provided.
[0017]
In such a configuration, the plurality of ventilation paths are provided in the hole, and are formed by an in-hole space dividing member that divides the in-hole space along the ventilation direction in the hole.
[0018]
The in-hole space dividing member is characterized in that it is twisted through the air passage so that one space partitioned by the partition member cannot see the other space. The hole space dividing member is formed of a heat exchange material. The hole space dividing member has a pollen adsorbing function of adsorbing pollen in a passing airflow.
[0019]
The plurality of ventilation paths may be formed by providing a ventilation pipe in the hole that passes through the pipe along the ventilation direction in the hole. At least a part of the plurality of ventilation paths is bent through the ventilation paths so that one space partitioned by the partition member cannot see the other space.
[0020]
Alternatively, a plurality of the ventilation pipes are provided, and at least two of the ventilation pipes are entangled with each other, and the other space cannot be seen from one space partitioned by the partition member through the two ventilation pipes. May be twisted as follows.
[0021]
Alternatively, the ventilation pipe is provided in a double cylindrical shape with respect to the ventilation hole, and one of the inside and outside of the ventilation pipe is used as an exhaust ventilation path, and the other is used as an intake ventilation path. It may be.
[0022]
In the ventilation hole formed by providing a ventilation pipe passing through the plurality of ventilation paths in the hole along the ventilation direction in the hole, the ventilation pipe formed as a straight pipe has a pipe length of Is set to be longer than the length along the ventilation direction of the ventilation hole formed in the straight hole.
[0023]
The open end of the ventilation hole is bent in a direction along the member surface of the partition member. The ventilation path outside the ventilation pipe is formed as a non-linear path so that the passing airflow does not travel straight from one pipe end to the other pipe end.
[0024]
The non-linear path is formed by providing an airflow course changing member that bends the course of the passing airflow in the ventilation path outside the pipe. The airflow course changing member is formed of a sound absorbing material.
[0025]
In addition, the configuration in which a non-linear path is set so that the passing airflow does not travel straight from one pipe end to the other pipe end is applied to a case where a single hole is formed without forming a plurality of air paths in the air hole. You can do it. That is, the present invention provides a ventilation hole which is provided to penetrate a partition member such as a wall and ventilates both spaces separated by the partition member. Is formed on a non-linear path so as not to go straight from the other end of the pipe.
[0026]
In the ventilation hole, the non-linear path is formed by providing an airflow course changing member that bends the course of the passing airflow in the ventilation hole. Further, the airflow course changing member may be formed of a sound absorbing material.
[0027]
In addition, in order to provide a ventilation hole of a fan device which is not restricted by an installation position in consideration of electric wiring and the like, in the ventilation hole of any one of the above configurations, the ventilation hole includes a solar cell. Is provided with a ventilating fan using the as an operating power source.
[0028]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0029]
(Embodiment 1)
In the present embodiment, a configuration in which a plurality of ventilation pipes are provided in a ventilation hole and a plurality of ventilation paths are provided will be described.
[0030]
FIG. 1A is an end view showing the open end of the ventilation hole of the present invention viewed from the outdoor side, FIG. 1B is a sectional view showing the appearance of the ventilation hole along the ventilation direction, and FIG. () Is an end view showing the appearance of the open end of the ventilation hole as viewed from the indoor side.
[0031]
The ventilation hole 10 of the present invention is provided through a partition member A as an outer wall of a structure such as a building. The inner space on the indoor side and the outer space on the outdoor side, which are partitioned by the partition member A, are connected to each other through the ventilation holes 10 so as to allow ventilation.
[0032]
The ventilation hole 10 has a double structure in which the ventilation pipe 20 is inserted in a double cylindrical shape. As shown in FIGS. 1A and 1B, the ventilation pipe 20 is provided with a fan 30 at the end of the pipe on the outdoor side for exhaustion, and the interior of the pipe exhausts indoor air from the internal space to the external space. It is used as the ventilation path 21, that is, as the exhaust path 21a (21).
[0033]
On the other hand, a space formed in a substantially ring shape outside the ventilation pipe 20, that is, around the ventilation pipe 20 in the ventilation hole 10 is used as the ventilation path 11, and the intake path 11 a (11 ). A plurality of ventilation paths 11 and 21 that can perform intake and exhaust in parallel by forming a double pipe in this way are formed in the ventilation hole 10.
[0034]
As shown in FIG. 1B, a pipe end flange 12 of the ventilation hole 10 is attached to the surface of the partition member A, and between the pipe end flange 12 and the pipe end flange 22 of the ventilation pipe 20. A predetermined interval is provided, and they are formed in the external space side opening 13a and the internal space side opening 13b which communicate with the ventilation path 11, respectively.
[0035]
The outer space side opening 13a and the inner space side opening 13b are bent in the direction along the surface of the partition member A, unlike the opening end side of the ventilation pipe 20, so that the indoor air exhausted from the ventilation pipe 20 is discharged outside. It is configured such that outside air that has entered the space side opening 13a or the indoor side from inside the ventilation path 11 does not flow into the interior space side opening 13b side by short circuit.
[0036]
If the interior space side opening portion 13b of the ventilation hole 10 is worrisome on the indoor side in design, such a configuration for preventing short circuit is eliminated, and the interior surface of the partition member A is substantially exposed to the surface. It can also be configured as one.
[0037]
At both open ends of the outer space side opening 13a, the inner space side opening 13b, and the ventilation pipe 20, protective nets 14 are provided on the opening sides, respectively, to prevent danger and to provide birds and insects in the ventilation paths 11, 21. And other foreign matter such as large dust is prevented from entering.
[0038]
A solar cell 40 is provided on the outer space, that is, on the surface of the tube end flange 22 facing the outdoor side. The fan 30 is operated by the electricity generated by the solar cell 40. As shown in FIG. 1B, a rechargeable battery 41 is provided on the indoor side so as to store surplus electricity when the fan 30 is not used. By providing such a rechargeable battery 41, the fan 30 can be operated even during a time period when power is not directly supplied from the solar cell, such as at night. At the same time, a switch 31 for the motor of the fan 30 is also provided indoors.
[0039]
Although not shown, when a louver or a shutter is provided at the open end on the outdoor side, the switch 31 may be configured as an electromagnetic switch or the like so as to synchronize with opening of the louver or the shutter or the like.
[0040]
The installation place of the solar cell 40 may be other than the surface of the tube end flange 22. Although it may be provided integrally with the ventilation hole 10 as shown in the figure, it may be provided separately on another wall surface of the building where the amount of solar radiation can be secured. What is necessary is just to select a position with good power generation efficiency.
[0041]
As the fan 30, a fan with a small motor used for cooling electronic equipment such as a personal computer is used.
[0042]
As described above, in the ventilation hole of the present invention, since the solar cell 40 is provided as an operating power supply of the fan 30 on the surface of the tube end flange 22, electric wiring for driving the fan from an outlet or the like provided indoors or outdoors is routed. There is no necessity, and there is no restriction on the installation position in consideration of electric wiring unlike a fan-equipped ventilation fan of the conventional configuration.
[0043]
In the ventilation hole 10 having such a configuration, a splitter 50a in which a cross section is combined in a cross shape in order to divide the ventilation paths 11 and 21 into a plurality of ventilation paths is provided as a hole space dividing member 50.
[0044]
By the splitter 50a (50), as shown in FIG. 1 (C), the ventilation path 11 is further connected to four ventilation paths 11b (11), 11c (11), 11d (11), and 11e (11). The ventilation path 21 in the trachea 20 is divided into four ventilation paths 21b (21), 21c (21), 21d (21), and 21e (21).
[0045]
The splitter 50a (50) is formed of a heat exchange functional material, and is used to ventilate warm indoor air from the indoor space on the indoor side to the external space on the outdoor side through the ventilation path 21 of the ventilation pipe 20. Heat can be exchanged between the outside air and the cold air that is drawn into the internal space through the passage 11. Examples of such a heat exchange material include Japanese paper, nonwoven fabric, metal plates (including metal thin films), resin materials such as plastics, and polymer film materials.
[0046]
If the splitter 50a is provided with such a heat exchange function, especially in winter, when outside air is introduced for ventilation, warm air escapes and cool outside air is introduced, so that the heated room suddenly cools down. However, if such a configuration is adopted, the cold outside air is warmed halfway and is taken into the room, so that a sudden decrease in the room temperature due to ventilation can be suppressed. The heating load associated with indoor ventilation can be reduced.
[0047]
On the contrary, in summer, in order to exhaust cold indoor air for the purpose of ventilation, outside air higher than the indoor temperature is somewhat cooled by the splitter 50a when entering the room and is taken into the room, so that ventilation The accompanying indoor cooling load can be reduced.
[0048]
Of course, when it is not necessary to consider the load suppression in the indoor heating and the indoor cooling, the splitter 50a does not have to be made of the heat exchange material.
[0049]
Further, the splitter 50a having the above configuration is twisted so that the room air exhausted from the internal space to the external space does not go straight to the external space. In the configuration shown in FIG. 1B, the splitter 50a is rotated such that the phase of the split end of the splitter 50a is 90 ° different from that of the split end of the splitter 50a by 90 ° so that the splitter 50a cannot see through the splitter. It is twisted.
[0050]
By setting the splitter 50a in a twisted configuration in this way, the flow velocity is reduced more than in the case where the air flow goes straight from the opening end on one space side to the opening end on the other space side. Thus, heat exchange can be sufficiently performed.
[0051]
Further, by twisting the splitter 50a, a noise reduction effect is obtained due to abrasion attenuation on the route, and it is possible to prevent external noise from entering the indoor space through the ventilation holes 10, that is, to obtain a sound insulation effect. At the same time, it is possible to prevent light from entering the internal space from the outside. That is, the light shielding function can be exhibited.
[0052]
As described above, since the main configuration that exhibits such a function is formed in the ventilation hole 10, there is no need to enlarge the configuration of the ventilation hole 10, and the ventilation hole having a normal size, for example, a diameter of about 150 φ is not necessary. Can be applied to
[0053]
It should be noted that the twisting as described above increases the pressure loss when the airflow passes and reduces the amount of ventilation, but such loss can be compensated by the fan 30.
[0054]
Further, in the above description, the splitter 50a is twisted by 90 °, but may be twisted beyond 90 °. Alternatively, when it is not necessary to consider the light shielding function, a configuration in which no twist is provided or a configuration in which the twist is less than 90 ° may be employed.
[0055]
In the above description, a configuration in which the outer space side opening 13a and the inner space side opening 13b are bent to prevent a short circuit has been described. Even if the trachea 20 is made longer than the length of the straight hole of the passage hole 10 so that the tube end projects, the short circuit can be prevented.
[0056]
In the above description, the splitter 50a that divides the inside of the ventilation paths 11 and 21 is twisted in the same direction by 90 ° in both the ventilation paths, but the splitter 50a is twisted between the inside of the ventilation path 11 and the inside of the ventilation path 21. The twisting direction can be reversed. By reversing the twisting direction in this way, the short cut can be prevented.
[0057]
Incidentally, the configuration for reversing the twisting direction may be formed, for example, as follows. That is, a shape in which a cross-section splitter 50a having a cross section is provided in a straight vent hole is formed by extrusion molding, and then the center portion is again cut out, and a plate material corresponding to the thickness cut off by the blade is spread around the periphery. By inverting the insertion, it is possible to form a configuration in which the twisting directions of the splitter 50a inside and outside the pipe are reversed. Such a configuration can be easily processed by using a resin material.
[0058]
In the above description of the present embodiment, the case where the inside of the ventilation pipe 20 of the ventilation hole 10 configured as a double structure, that is, the ventilation path 21 is configured for exhaust, and the outside of the pipe, that is, the ventilation path 11 is configured for intake, is described. Although described as an example, the ventilation path 21 in the ventilation pipe 20 may be configured for intake and the ventilation path 11 outside the pipe may be configured for exhaust.
[0059]
(Embodiment 2)
In the present embodiment, a description will be given of a configuration in which a plurality of ventilation paths are provided by dividing into a plurality of spaces by a space dividing member without providing the ventilation pipe 20 in the hole of the ventilation hole 10.
[0060]
FIG. 2A is an end view showing the open end side of the ventilation hole of another configuration of the present invention viewed from the outdoor side, and FIG. 2B is a view along the ventilation direction of the ventilation hole of FIG. FIG. 4C is a cross-sectional view showing the inside of the hole, and FIG. 4C is an end view showing the state of the open end of the ventilation hole viewed from the indoor side.
[0061]
Similarly to the first embodiment, the ventilation hole 10 of the present embodiment is provided through a partition member A as an outer wall of a structure such as a building. The inner space on the indoor side and the outer space on the outdoor side, which are partitioned by the partition member A, are connected to each other through the ventilation holes 10 so as to allow ventilation.
[0062]
Unlike the first embodiment, the ventilation hole 10 has no ventilation tube 20 inserted therein. A fan 32 is provided at the outdoor pipe end of the ventilation hole 10, and by controlling the forward / reverse rotation of the fan 32, exhaust from the internal space to the external space and intake from the external space to the internal space can be performed. It is configured as follows.
[0063]
That is, the inside of the ventilation hole 10 is configured as a ventilation path 11 that can be used for intake or exhaust by controlling the forward / reverse rotation of the fan 32.
[0064]
A tube end flange 12 of the ventilation hole 10 is attached to the surface of the partition member A, and a solar cell 40 is provided on the surface of the tube end flange 12 that is exposed to the outside. The fan 32 uses the solar cell 40 as an operation power supply. On the indoor side, as shown in FIG. 2B, a rechargeable battery 41 and a switch 33 for starting / stopping the fan 32 and for switching between forward and reverse directions are provided so as to store surplus electricity.
[0065]
By using the solar battery 40 as the operating power supply of the fan 32, it is not necessary to draw the electric wiring for driving the fan from the outlet as described in the first embodiment, and the installation position is limited in consideration of the electric wiring. Absent.
[0066]
A protection net 14 is provided on the opening side of both ends of the ventilation hole 10 so that birds and insects do not enter the ventilation path 11 and foreign substances such as large dusts do not enter the ventilation path 11.
[0067]
In the ventilation hole 10 having such a configuration, a splitter 50a in which a cross section is combined in a cross shape to divide the ventilation path 11 into a plurality of ventilation paths is provided as a space division member 50 in the hole. By the splitter 50a (50), as shown in FIGS. 2A and 2C, the ventilation path 11 is further divided into four ventilation paths 11b (11), 11c (11), 11d (11), 11e (11). ).
[0068]
Further, the splitter 50a having the above configuration is twisted so that the room air exhausted from the internal space to the external space does not go straight to the external space. As shown in FIGS. 2A, 2B, and 2C, the inner space side opening end 51 side and the outer space side opening end 52 side of the splitter 50a are connected so that the outer space cannot be seen through the inner space. It is rotated and twisted so that the phases differ by 90 °.
[0069]
As described above, in the ventilation hole 10 having the configuration shown in FIG. 2, since the inside of the hole is divided into a plurality of ventilation paths by the splitter 50 a and the splitter 50 a is twisted, the penetration of sound from the outside is prevented. The sound insulation function is exhibited. At the same time, a light shielding function is also exhibited.
[0070]
In order to further enhance the sound insulation function, it is effective if the splitter 50a is made of a sound absorbing material such as glass wool.
[0071]
(Embodiment 3)
In the first embodiment, a configuration is shown in which one ventilation pipe 20 is passed through the ventilation hole 10 in a double cylindrical shape and a plurality of ventilation paths are provided in the straight ventilation hole 10. As shown in (A), a plurality of ventilation pipes 23 having a small pipe diameter may be inserted to form a large number of ventilation paths 23a.
[0072]
FIG. 3A is an end view showing the ventilation hole 10 as viewed from the tube end flange 12 side, and the configuration of the protection net 14 is omitted for easy viewing.
[0073]
In the case shown in FIG. 3A, a state is shown in which a large number of ventilation pipes 23 are packed in the ventilation holes 10, but as shown in FIG. It is also conceivable that the ventilation pipe 24 having such a configuration is inserted into the ventilation hole 10 in a double cylindrical shape.
[0074]
Although not shown, a plurality of ventilation pipes 23 may be inserted into the ventilation holes 10 so as to be entangled. For example, the two ventilation pipes 23 may be entangled by twisting a cord. Further, two or more bundles composed of a plurality of vent pipes are prepared, and these bundles are knitted with wires. This is preferable in that it is possible to prevent both spaces from being seen through a pipe near the center, which is likely to occur when one bundle is simply twisted, and that an approximately equal load can be applied to each ventilation pipe. By twisting the ventilation pipe in this manner, a similar effect can be obtained by twisting the splitter 50a.
[0075]
In the first and second embodiments, the case where the configuration of the splitter 50a is formed into a cross-shaped cross section and divided into four is described as an example. However, the configuration of the splitter 50a is not limited to such a configuration. For example, as shown in FIG. 3C, the image may be divided into eight or more. It may be divided into a honeycomb.
[0076]
Further, the division is illustrated as an example in which the division is performed so that the cross-sectional area becomes equal, but the division may be performed unequally.
[0077]
Further, in the above description, the case where the cross-sectional shape of the vent hole 10 is configured as a circular tube has been described as an example, but the cross-sectional shape need not be limited to such a circular tube. For example, as shown in FIGS. 4A and 4B, it may be formed in a square tube. In the configuration shown in FIG. 4A, the splitter 50a having a cross-shaped cross section is disposed so as to be located on a diagonal line of the square tube.
[0078]
Furthermore, although the case where the shape of the splitter 50a is formed in a radial cross section has been described above, the splitter 50a may be formed in a cross sectional lattice shape as shown in FIG. Further, a large number of small-sized thin tubes may be packed in the vent hole 10 formed in a square tubular shape.
[0079]
The material of the thin tubes such as the splitter 50a and the ventilation tube 23 may be selected from materials suitable for the purpose of use, such as metals and resin materials such as plastics. For example, when emphasizing the sound absorbing effect, the splitter 50a and the thin tube may be made of a porous material such as glass wool, cotton, and asbestos, or a sound absorbing material such as a ceramic or a fired aluminum plate. In particular, use of glass wool is preferable in consideration of safety, cost, and the like.
[0080]
When ceramic is used, for example, the entire ventilation hole 10 including the thin tube such as the splitter 50a and the ventilation tube 23 may be made of ceramic. When the heat exchange function is emphasized, it may be made of Japanese paper or the like as described above.
[0081]
As for the relationship between the number of divisions by the splitter 50a and torsion, the greater the number of divisions in the vent hole 10, the smaller the angle of torsion. Furthermore, the longer the length of the inside of the ventilation hole 10 and the length of the ventilation pipe 23 and the like, the lower the ventilation rate due to pressure loss, and the greater the sound insulation effect. Therefore, the number of divisions may be appropriately adjusted in accordance with the required specifications in relation to the length in the hole, the length of the pipe, the reduction in the amount of ventilation, and the sound insulation effect.
[0082]
(Embodiment 4)
In the present embodiment, a configuration is provided in which the splitter 50a as the in-hole space dividing member 50 described in the first to third embodiments is provided with a pollen adsorption function of adsorbing pollen in an airflow passing through the air hole 10. explain.
[0083]
For example, as shown in FIG. 2, a splitter 50a is provided in the vent hole 10, and although not shown, a part of the bearing of the fan 32 is brought into contact with the splitter 50a. If the splitter 50a is formed of a resin material or the like, it can be frictionally charged by contact with the bearing and adsorb pollen. Of course, it is also effective in adsorbing dust and the like other than pollen.
[0084]
The pollen adsorption function may have a configuration other than the above configuration. For example, an electric field is generated in the splitter 50a by another electric field generating unit using the electric power obtained by the solar cell 40, and the pollen is absorbed in the airflow passing through the ventilation hole 10. The pollen may be adsorbed on the surface of the splitter 50a.
[0085]
The splitter 50a may be formed by sticking a resin or the like that generates static electricity on the surface or by using a resin material. In addition, if the splitter 50a having such a configuration is configured so that it can be detachably inserted into and removed from the vent hole 10, it is possible to periodically clean the adsorbed pollen by washing the splitter 50a with water, suctioning with a vacuum cleaner, or the like. It is possible and preferable.
[0086]
In particular, by using the splitter 50a having a torsion configuration, the speed of the passing airflow can be reduced as compared with the case of the straight configuration, and further, when the above-described suction configuration is employed only on the inner wall of a straight hole. In comparison, the adsorption area can be increased, and the pollen adsorption ability can be significantly improved.
[0087]
As described above, pollen can be adsorbed with a relatively simple configuration when air is taken indoors by using the ventilation hole 10, so that pollen can be removed to some extent even if pollen cannot be completely removed. In addition, the effect can be expected as a help of the hay fever countermeasures based on ventilation, ventilation, and the like at the time when a large amount of pollen is scattered.
[0088]
(Embodiment 5)
In the present embodiment, a configuration in which a sound insulating function and a light shielding function are provided in the ventilation hole 10 without forming a plurality of ventilation paths in the ventilation hole 10 will be described. FIG. 5 is a perspective view showing the inside of the ventilation hole 10 provided with the sound insulation function described in the present embodiment.
[0089]
As shown in FIG. 5, the ventilation hole 10 is formed in a square tube, and is configured such that an airflow flows from one tube end to the other tube end to allow ventilation.
[0090]
In the hole, an airflow course changing member 60 is provided so as to block the airflow that travels straight in the transverse direction along the ventilation direction and forcibly change the course of the airflow. In the case shown in FIG. 5, a partition plate 60a is provided as the airflow course changing member 60.
[0091]
The width L of the partition plate 60a is set to, for example, the inner width of the ventilation hole 10 and the height H thereof is set to be higher than half the height h of the ventilation hole 10 inside the hole. The partition plate 60a having such a configuration is provided alternately from the ceiling side in the hole and from the bottom side in the hole.
[0092]
As shown by the arrow in FIG. 5, the air flow enters through one of the pipe end openings of the ventilation hole 10 and proceeds straight, but is blocked from going to the partition plate 60 a hanging down from the ceiling in the hole, and the lower end of the partition plate 60 a is blocked. I was forced to change course to go around the side. At that point, the path is again interrupted by the partition plate 60a erected from the bottom surface side, and the vehicle goes around while grazing the upper end side.
[0093]
However, the partition plate 60a, which is suspended again from the ceiling side, stands at the end of the travel, so that the partition plate 60a goes around the lower end again, and finally exits from the other pipe end opening.
[0094]
In this way, the air flow is meandered by the partition plate 60a as the air flow path changing member 60 without going straight from one tube end opening to the other tube end opening.
[0095]
As the airflow advances while meandering, the speed of the airflow is suppressed, and the passing sound can be reduced as compared with the case where the airflow travels straight at a high speed. Further, since the sound waves from the outside are also prevented from going straight by the partition plate 60a, the sound insulating effect can be remarkably exhibited as compared with the case where the sound waves go straight into the indoor space. More preferably, if the partition plate 60a as the airflow course changing member 60 is formed of a sound absorbing material, the sound insulating effect can be more effectively secured.
[0096]
The partition plate 60a prevents not only sound waves but also external light from traveling in a straight line, so that a sufficient light shielding effect can be exhibited.
[0097]
The configuration in which the partition plate 60a is provided may be provided in the air passage 11 of the first embodiment.
[0098]
As the airflow course changing member 60, a configuration other than the partition plate 60a may be used, and a corrugated plate that repeats irregularities in a long cycle on the ceiling side and the bottom side of the hole 10 is formed such that the concave portions and the protruding portions match each other. May be provided so that the air flow can meander along the uneven surface of the corrugated plate. Alternatively, the vent hole itself may be configured to meander along the direction of air flow.
[0099]
The present invention is not limited to the above-described embodiment, and may be changed as needed without departing from the gist thereof.
[0100]
For example, in the above description, the configuration in which the fan is provided on the outdoor side of the ventilation hole is described as an example, but the configuration may be such that the fan is also provided on the indoor side. Alternatively, a configuration may be provided only on the indoor side. Also, the number of fans to be installed is one, but a configuration in which a plurality of fans are provided according to a plurality of ventilation paths provided in the ventilation holes is also conceivable.
[0101]
In the above description, the case where the splitter is made of the heat exchange function material is shown, but the splitter may be made of the sound absorbing material. Alternatively, a heat exchange function material or a sound absorbing material may be attached to the surface of the splitter. The same applies to the ventilation pipe, and the ventilation pipe itself may be formed of a heat exchange material or a sound absorbing material, or may be attached to at least one of the inside and outside of the pipe.
[0102]
Further, such a configuration can be applied to the airflow course changing member. The airflow course changing member itself may be formed of a heat exchange function material or a sound absorbing material, or may be attached to the surface thereof.
[0103]
Further, in the above description, the outer wall of the building is exemplified as the partition member provided with the ventilation hole. However, the partition member does not need to be limited to the outer wall. It does not matter even if it is an inner wall that separates the walls. Further, in addition to buildings, the present invention can be applied to underground structures such as subways and underground malls.
[0104]
【The invention's effect】
The main effects of the present invention are as follows.
[0105]
That is, according to the present invention, the ventilation hole can be provided with a sound insulation function other than the ventilation function, a light shielding function, a heat exchange function, or a pollen removing function, in addition to the ventilation and ventilation functions.
[0106]
In particular, by providing a configuration for performing such a function inside the ventilation hole, the configuration can be made more compact than when the generation mechanism for such a function is provided outside the ventilation hole.
[0107]
When a fan is provided in the ventilation hole, the operation power source is a solar cell, so that the installation position can be freely selected without considering the routing of electric wiring from the outlet.
