Definitions

  • the present invention relates to a ventilating apparatus provided at an air vent formed in an outer wall of a building for natural ventilation, the ventilating apparatus including a member that closes an opening closer to the interior. More specifically, the present invention relates to a ventilating apparatus that is useful both for ventilation and for deadening of external noise entering the room.
  • a tight concrete building such as an apartment has an air vent formed in its outer wall for ventilation.
  • the air vent is a hole that penetrates the outer wall.
  • the air vent generally has an outer part covered with an outer wall hood to prevent rainwater from entering the room.
  • an opening and closing mechanism is installed in the room; the opening and closing mechanism is called a louver or a ventilating register and enables the air vent to be opened and closed.
  • the louver is composed of for example, a cover made of stainless steel or plastics and having an opening in a part of it and a rotating plate that rotates inside the cover to open and close the opening.
  • the louver allows outer air introduced into the air vent to be blown out, via a filter or a wire mesh, into the room as it is.
  • the ventilating hole is a through-hole, external noise enters the room as it is unless certain sound insulating measures are taken.
  • a sound absorbing member is disposed in the outer wall hood of the ventilating hole (see Japanese Utility Model Laid-Open No. 5-59142).
  • the conventional interior opening and closing mechanism called the louver or ventilating register is not recognized as one of interior decorations. Accordingly, the opening and closing mechanism consists of a cover made of steel or plastics and having a large opening in a front surface and a plate laid on top of the cover. Thus, disadvantageously, the opening and closing mechanism is insufficiently decorative. As a result, the user disadvantageously hides the ventilating hole behind furniture or the like.
  • the sound deadening mechanism is installed in an air vent formed in a wall of thickness at most ten cm or more. Accordingly, the sound deadening mechanism is mainly composed of a sound absorbing material and thus has a low sound deadening effect at less than 1 kHz. In addition, the sound deadening mechanism has such a complicated attachment structure as must be handled by experts in maintenance. It is thus difficult for residents to replace the sound deadening mechanism with a new one.
  • the present invention provides a ventilating apparatus installed in a ventilating hole drilled in an outer wall of a building to enable natural ventilation, the apparatus comprising a sound deadening cartridge installed in the ventilating hole and a cap cover detachably installed in an interior opening of the ventilating hole to cover the sound deadening cartridge and thus the interior opening of the ventilating hole, the cap cover having an air outlet through which introduced external air having passed through the sound deadening cartridge is blown out into a room, wherein the air outlet is placed along a wall surface to allow the introduced external air to flow out along the wall surface.
  • the cap cover includes a mounting base fixed to the ventilating hole and a front cover detachably attached to the mounting base.
  • the sound deadening cartridge is detachably attached to a rear surface of the front cover. In this case, removal of the front cover from the mounting base allows the whole sound deadening cartridge to be removed from the ventilating hole.
  • the sound deadening cartridge can be installed in the ventilating hole by removing and replacing the sound deadening cartridge with a new one and then attaching the front cover to the mounting base again. Therefore, the sound deadening cartridge can be easily replaced with a new one even by a person who is not an expert in maintenance.
  • the front cover has a ring-like attachment member that can be attached to and detached from the mounting base so that an air outlet is formed between the cover and the attachment member.
  • the position at which attachment member of the cap cover is installed on the mounting base it is possible to change the position and direction of the air outlet as well as position of a control plate.
  • This in turn enables a change in the direction of a normally open portion of the air outlet and in the position of the control plate. That is, the position and direction of the normally open portion and adjustment section can be approximately changed in association with the appropriate position and direction of the normally open portion and adjustment section which vary depending on the mounting position of the ventilating apparatus and the arrangement of furniture or the like.
  • opening and closing the control plate allows the quantity of airflow to be adjusted but also enables a change in air blowout direction and width.
  • the cap cover preferably has a top panel that can be attached to and detached from the front cover, on a front surface of the front cover.
  • the design can be changed by replacing the top panel, which occupies a large area of the front cover, with a different one.
  • the top panel is transparent, an arbitrary design, for example, an exhibit such as a favorite photograph, picture, pattern, wall paper, or pressed flower can be decorated between the top panel and the front cover. Therefore, the ventilating apparatus can be utilized as interior decoration.
  • the air outlet preferably comprises a normally open portion and an adjustment area in which a control plate is placed, for opening and closing a part of the air outlet so that the amount of air introduced can be controlled.
  • the air outlet is partly arbitrarily opened and closed by the control plate to enable adjustment of the amount of external air introduced and the external air blowout direction.
  • at least a part of the air outlet is normally open and is not closed up. This ensures sufficient natural ventilation.
  • the air outlet may be formed parallel to the wall surface so as to be open in all directions and may be normally open. In this case, the air outlet is always open in any direction regardless of the arrangement of furniture or the like and is thus not closed up. This ensures sufficient natural ventilation.
  • control plate is placed between the front cover of the cap cover and an attachment member.
  • the control plate is fitted into a guide groove formed along edges of the front cover and attachment member and is supported so that the control plate can slide in the guide groove along the edges.
  • opening and closing the control plate enables not only adjustment of the quantity of airflow but also a change in air blowout direction or width.
  • the normally open portion is located in an upper part of the air outlet; the normally open portion remains open even when the control plate is fully closed.
  • external air is always blown upward out of the normally open portion, which is not closed up, and along the wall surface. Consequently, introduced external air is blown out into the room without making the residents unconscious of the blowout.
  • the external air is blown out along the wall surface toward the ceiling. The external air can thus be spread quickly throughout the room.
  • the blowout of the introduced external air converges on the ceiling. This prevents a person or an object standing below the ventilating apparatus from being exposed directly to the external air.
  • the sound deadening cartridge consists of an expanding silencer and a sound absorbing material which covers an inner surface of the expanding silencer and an external air inlet and which also acts as a filter.
  • the sound deadening cartridge when external air introduced into the room as a result of natural ventilation or forced exhaust ventilation passes through the sound deadening cartridge, dust and possibly pollen and the like are removed and prevented from entering the room.
  • sound deadening and attenuation are carried out over a wide frequency band from low to high frequencies as a result of attenuation based on expansion and resonance and attenuation based on sound absorption.
  • the external air is blown slowly out of the air outlet in all directions, the air outlet being open along the wall surface.
  • a mixture of antibacterial, deodorant metal and titanium oxide with antibacterial, deodorant ceramic is attached to the sound absorbing material.
  • the surface of the sound deadening material also serving as a filter, captures and kills germs, which are contained in the air and which causes a stench, to prevent their propagation. This makes it possible to prevent a stench or bacteria from entering the room.
  • a detachable pre-filter preferably externally covers an external air inlet in the sound deadening cartridge. More preferably, the detachable filter covers the outside of the sound absorbing member which covers the external air inlet in the sound deadening cartridge and which also serves as an air filter. In this case, dust or pollen entrained in introduced external air can be removed by the pre-filter before being introduced into the sound deadening cartridge. The sound absorbing material in the sound deadening cartridge is unlikely to be clogged. This makes it possible to increase the amount of time before the sound deadening cartridge itself must be replaced with a new one.

  • FIG. 1 to 10 shows an embodiment of the present invention.
  • the ventilating apparatus is installed in a ventilating hole 2 drilled in an outer wall 1 of a building to enable natural ventilation.
  • the ventilating apparatus comprises a sound deadening cartridge 10 installed in the ventilating hole 2 and a cap cover 20 detachably installed in an interior opening 6 of the ventilating hole 2 and covering the sound deadening cartridge 10 and thus the interior opening 6 of the ventilating hole 2.

  • the front cover 22 has a ring-like attachment member 25 that can be attached to and detached from the mounting base 21.
  • the air outlet 24 is formed by creating a space between the attachment member 25 and the front cover 22.
  • the mounting base 21 and the front cover 22 are connected together by installing the attachment member 25, having a pawl, between the mounting base 21 of the cap cover 20 and the front cover 22.
  • the air outlet 24, which blows out into the room 4 introduced external air having passed through the sound deadening cartridge 10, is formed between the mounting base 21 and the front cover 22. That is, the front cover 22 is attached to the attaching pawl 26 of the attachment member 25, detachably attached to the mounting base 21, fixed to the outer wall 1.
  • a space of a specified size is created between the attachment member 25, integrated with the mounting base 21, and the front cover 22, to constitute the air outlet 24.

  • the normally open portion 32 is placed to face upward, while the normally closed portion 34 is placed to face downward.
  • Normally introduced external air is blown out mainly upward around a vertical axis and along the wall. The external air is not blown out toward the residents' feet or the floor.
  • the angles of the normally open portion 32, normally closed portion 34, and adjustment area 33 are limited to the above values. Of course, these values can be freely set.
  • the control plate 30 is placed in the air outlet 24 and can partly open and close the air outlet 24 to control the amount of external air introduced.
  • the control plate 30 is placed between the front cover 22 of the cap cover 20 and the mounting base 21.
  • the control plate 30 is fitted into a guide groove 31 formed along edges of the front cover 22 and mounting base 21. The control plate 30 is thus supported so that it can slide through the guide groove 31 along the edges. Even when the control plate 30 is fully closed, the upper normally open portion 32 of the air outlet 24 remains open.
  • the mounting base 21 has a cylindrical portion 21a inserted into the interior opening 6 of the ventilating hole 2, drilled in the outer wall 1, and a flange portion 21b extending radially outward from the edge of the opening 6. With the cylindrical portion 21a inserted into the ventilating hole 2, the flange portion 21b is fixed to the wall surface 8 using screws or the like.

More preferably, a mixture of an antibacterial, deodorant metal and titanium oxide with antibacterial, deodorant ceramic is attached to in the sound absorbing materials 19 and 37 or the sound absorbing materials 19 and 37 are impregnated with the mixture. In this case, while introduced external air is passing through the sound deadening cartridge, the surface of the sound deadening materials, also serving as filters, capture and kill germs, which are contained in the air and which causes a stench.

  • the mounting base 21 is then fixed using screws (not shown) or the like.
  • the hooks 22b on the rear surface of the front cover 22 are utilized to fix the cap cover 20 to the mounting base 21 via the attachment member 25; the sound deadening cartridge 10 has been attached to the cap cover 20.
  • the cap cover 20 is fixed to the mounting base 21 simply by performing the following operation.
  • the introducing portions 25a' of the L-shaped engagement grooves 25a in the attachment member 25 are inserted around the corresponding hooks 21c, projecting from the mounting base 21; the sound deadening cartridge 10 has been inserted into the ventilating hole 2 through the opening in the mounting base 21.
  • the cap cover 20 is slightly rotated in the engaging direction.
  • the cap cover 20, consisting of the attachment member 25, intermediate ring 27, front cover 22, and control plate 30, is fixed to the mounting base 21 after having been assembled into one member. That is, the intermediate ring 27 and the front cover 22 are sequentially fitted into the attaching pawls 26 of the attachment member 25.
  • the control plate 30 is inserted into a predetermined position between the front cover 22 and the attachment member 25. The opposite edges of the control plate 30 are fitted into the guide groove 31. The tips of the attaching pawls 26 of the attachment member 25 are inserted into and coupled to the holding portions 22a of the front cover 22.
  • the front cover 22 is fixed to the outer wall 1 via the attachment member 25 and the mounting base 21.
  • the sound deadening cartridge 10 is attached to the rear surface of the front cover 22. Accordingly, the sound deadening cartridge 10 is supported in the ventilating hole 2 via the front cover 22.
  • the sound deadening cartridge 10 is fixedly attached to the front cover 22 by fitting the hooks 22b into the corresponding L-shaped grooves 11a, and then slightly rotating the sound deadening cartridge 10 on the hooks 22b; the hooks 22b are provided on the rear surface of the front cover 22 and are open in an externally radial direction, and the L-shaped grooves 11a are formed in the front surface of the front case 11. Accordingly, the sound deadening cartridge 10 can be removed from the front cover 22 simply by pulling the sound deadening cartridge 10 while rotating it in a direction opposite to that for fixing with respect to the front cover 22. Consequently, the sound deadening cartridge 10 can be easily replaced with a new one.
  • the front surface of the front cover 22 is decorated with a favorite photograph, picture, pressed flower, wallpaper, or the like and is then covered with the transparent top panel 23.
  • the transparent top panel 23 is fixed by placing the projections 23a, provided around the periphery, in the corresponding engagement grooves 22c in the front cover 22 and then slightly rotating the top panel 23 in the circumferential direction for engagement. Accordingly, to replace the photograph or the like sandwiched between the front cover 22 and the transparent top panel 23, the top panel 23 has only to be removed by rotating it in the opposite direction.
  • the installation of the transparent top panel 23 changes the interior design of the ventilating apparatus. Consequently, it is possible to make an interior atmosphere suitable for the season by adopting a color or design suitable for the season to give a cold or warm feeling. Furthermore, not only the color but also the combination of the transparent top panel 23 and the front cover 22 may be varied.
  • the air outlet 24 is formed between the front cover 22 and the attachment member 25, it is possible to provide a large spacing between the front cover 22 and the attachment member 25. Pressure loss can be reduced by increasing the width of the air outlet 24. This improves the natural ventilating capability.
  • the ventilating apparatus according to the present embodiment instead of flowing straight, introduced external air collides against the wall of front case of the sound deadening cartridge 10 and then flows into the room while spreading parallel to the wall surface and radially outward (radiantly). Accordingly, the ventilating apparatus according to the present invention comprises a sound insulating function to attenuate the propagation of outdoor noise to the indoor. Therefore, the ventilating apparatus according to the present invention can ventilate not only general homes but also rooms in medical facilities or the like which must be quiet.
  • the sound absorbing material 19 may have a dust filtering function. This improves the purity of external air introduced into the room. Moreover, since natural ventilation is based on a difference in pressure between the indoors and the outdoors, external air free from pollen or the like can be introduced by employing a sound absorbing material having a pollen removing function or a separate filter.
  • the ventilating apparatus used for the measurement tests is shown in Figure 1.
  • the external cylinder 13 had a length L1 of 144 mm, an outer diameter of 136 mm, and an inner diameter of 130 mm.
  • the internal cylinder 14 had an inner diameter of 50 mm, an outer diameter of 55 mm, and a length L2 of 104 mm.
  • the external air inlet 15 was formed in the internal cylinder 14 at a position 10 mm away from the end of the external cylinder 13.
  • the exhaust port 16 in the external cylinder 13 had eight openings each of length 32 mm and angle of aperture 40°.
  • the maximum opening of the air outlet 24 and the normally closed area were 220° and 140°, respectively.
  • the tests were conducted using a method for displaying and measuring environmental noise in accordance with JIS-Z8731.
  • the results of the present tests showed a significant improvement in sound insulation over the entire audible frequency band, particularly in a band of 200 Hz to 3.15 kHz compared to comparative examples 1 and 2.
  • a significant sound insulating performance was exhibited at a frequency of 500 Hz to 1 kHz.
  • the sound insulating effect can be improved. Further, since the exhaust port 16 is formed almost all along the circumference of the cartridge 10, the amount of ventilation is not substantially affected because the effective opening area is not substantially reduced.
  • a photograph or a pressed flower is accommodated below the transparent top panel 23 as a decoration.
  • various designs or photographs may be printed directly on the top panel 23 itself to provide top panels 23 with various colors or designs. Then, the interior design may be varied by changing the top panel 23.
  • the normally closed portion 34 is placed to face downward.
  • the normally open portion 32 is placed to face upward.
  • the adjustment area 33 is placed to face in a lateral direction.
  • the normally open portion 32 and the adjustment area 33 may be placed to face upward and downward, respectively, with the normally closed portion 34 sandwiched between them so that introduced external air can be blown out downward.
  • the normally open portion 32 can be placed in the lower part of the ventilating apparatus of the same structure by removing the attachment member 25 from the mounting base 21, rotating the attachment member through 180°, and then attaching it to the mounting base 21.
  • control plate (shutter) 30 may not only slide in the circumferential direction to change the opening of the air outlet 24 but also penetrate the front cover 22 so that it can move toward and away from the wall as shown in Figure 11. In the latter case, the opening can be adjusted between a fully closed state and a fully open state within a specified area.
  • a catching portion 36' is provided at a proximal end of the control plate 30 so that the user can utilize the catching portion 36' to move the control plate 30 in and out to adjust the opening of the air outlet 24.
  • This embodiment is free from the normally closed portion 34 and is composed only of the normally open portion 32 and the adjustment area 33. However, the normally closed portion 34 may be provided.
  • the front cover 22, the intermediate ring 27, and the attachment member 25 are pre-assembled and integrated into one block, which can then be detachably attached to the mounting base 21.
  • the present invention is not limited to this. All the parts may be sequentially assembled to and disassembled from the mounting base 21.
  • an operation of replacing the sound deadening cartridge 10 is performed by enabling only the front cover 22 and the sound deadening cartridge 10 attached to the front cover 22 to be attached to and detached from the attaching claws 26.
  • the front cover 22 is removed from the attaching pawl 26 to take the sound deadening cartridge 10 out of the ventilating hole 2.
  • the sound deadening cartridge 10 is replaced with a new one.

  • the attachment member 25 may be omitted and the attaching pawls supporting the front cover 22 and intermediate ring 27 may be projected directly from the mounting base 21. Then, the air outlet 24 is formed of a space created between the mounting base 21 and the front cover 22. In this case, an operation of replacing the sound deadening cartridge 10 is performed by enabling only the front cover 22 and the sound deadening cartridge 10 attached to the front cover 22 to be attached to and detached from the mounting base 21.
  • the air outlet 24 may be normally open in all directions.
  • the air outlet 24, through which introduced external air having passed through the sound deadening cartridge 10 is blown out into the room 4 may be open parallel to the wall surface 8 in all directions (360°) so as to allow the introduced external air to flow out along the wall surface 8.
  • the air outlet is always open in any direction regardless of the arrangement of furniture or the like and is thus not substantially closed up. This ensures sufficient natural ventilation.
  • the air outlet 24 is formed by connecting the mounting base 21 and the front cover 22 together between the mounting base 21 of the cap cover 20 and the front cover 22 via a second ring panel 25 with a pawl; introduced external air having passed through the sound deadening cartridge 10 is blown out into the room 4 through the air outlet 24.
  • One or more intermediate rings 27 function both as barricades inhibiting foreign matter from entering the air outlet 24 and as straightening vanes; the intermediate rings 27 have a simple structure in which they are fixedly arranged at constant intervals between the front cover 22 and the mounting base 21. Therefore, the air outlet 24 has a very simple configuration.
  • the remaining part of configuration of the air outlet 24 is basically the same as that in the embodiment shown in Figures 1 to 10 except that it is normally open in all directions.
  • the front cover 22, the intermediate ring 27, and the attachment member 25 may be assembled and integrated into one block and then detachably attached to the mounting base 21, as in the case of the ventilating apparatus according to the embodiment shown in Figures 1 to 10.
  • the control plate 30 since the control plate 30 is not placed between the front cover 22 and the attachment member 25, the parts may be sequentially assembled to the mounting base 21.
  • the attachment member 25 is fixedly caught on the mounting base 21, fixed to the outer wall 1.
  • the intermediate ring 27 is sequentially fixedly fitted into the attaching pawls 26 on the attachment member 25.
  • the sound deadening cartridge 10 is inserted into the ventilating hole 2 through the opening in the mounting base 21.
  • the tips of the attaching pawls 26 of the attachment member 25 are inserted into and coupled to the corresponding holding portions 22a of the front cover 22. This allows the front cover 22 and the sound deadening cartridge 10 to be fixed to the outer wall 1 via the second ring panel 25 and the mounting base 21.
