TECHNICAL FIELD [0001] 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. BACKGROUND ART [0002] 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. Accordingly, the air vent generally has an outer part covered with an outer wall hood to prevent rainwater from entering the room. Further, 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. [0003] However, since the ventilating hole is a through-hole, external noise enters the room as it is unless certain sound insulating measures are taken. [0004] Thus, as sound insulating measures for a ventilating hole in a sound insulating room, for example, a sound absorbing member is disposed in the outer wall hood of the ventilating hole (see Japanese Utility Model Laid-Open No. 5-59142). [0005] Further, a structure has been proposed in which a ventilating pipe having an opening in a side surface located above when the pipe is buried is installed in a ventilating hole penetrating the building, with the opening covered with a sound absorbing material (see Japanese Patent Laid-Open No. 2003-64797). [0006] However, in all these ventilating apparatuses, an air outlet is opened almost straight to the interior (even with the presence of a certain spread); introduced external air is blown out into the room through the air outlet. Accordingly, a person or an object standing in front of the wall is exposed directly to the introduced external air. This makes the person uncomfortable, so that the air outlet is often closed up. This results in insufficient ventilation, which in turn leads to a house dust problem or a sick house problem. Moreover, the sound absorbing material in the sound deadening mechanism may cause germs to propagate, resulting in a stench. Further, bacteria may enter the room. [0007] Furthermore, forced exhaust ventilation or the like using a ventilating fan or the like exerts a negative pressure on the interior. This may disadvantageously prevent a door from being opened. Moreover, 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. [0008] Moreover, if furniture, for example, a sofa, is placed below the air outlet, introduced external air falls on a person sitting in the sofa. The person may thus feel cold. If not only simple adjustment of the quantity of airflow but also a change in air blowout direction or width are desired, this cannot be achieved. [0009] Further, 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. [0010] It is an object of the present invention to provide a ventilating apparatus which makes the residents unconscious of blowout of introduced external air into the room and which can spread the air throughout the room quickly. It is another object of the present invention to provide a decorative ventilating apparatus that can be utilized as one of interior decorations. It is further another object of the present invention to provide a ventilating apparatus that has an excellent sound insulating effect. It is further another object of the present invention to provide a ventilating apparatus that allows a sound deadening mechanism to be easily replaced with a new one. DISCLOSURE OF THE INVENTION [0011] To accomplish the objects, 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. [0012] This prevents a person or an object standing in front of the wall from being exposed directly to the introduced external air. The person thus does not feel uncomfortable. Consequently, ventilation can be continued for 24 hours, thus reducing the amount of house dust and preventing a sick house. Further, no negative pressure is exerted, thus avoiding the problem that the door cannot be opened. Furthermore, the front surface of the front cover closing the ventilating hole can be decorated. This enables a novel design established as a part of interior decoration. [0013] 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. Moreover, 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. [0014] Further, in the ventilating apparatus according to the present invention, 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. In this case, by changing 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. Furthermore, 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. [0015] 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. In this case, the design can be changed by replacing the top panel, which occupies a large area of the front cover, with a different one. In particular, if 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. [0016] Further, in the ventilating apparatus according to the present invention, 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. In this case, 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. However, at least a part of the air outlet is normally open and is not closed up. This ensures sufficient natural ventilation. Further, 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. [0017] Moreover, the 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. In this case, 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. [0018] Further, in the ventilating apparatus according to the present invention, 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. In this case, 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. This ensures sufficient 24-hour natural ventilation. Furthermore, the external air is blown out along the wall surface toward the ceiling. The external air can thus be spread quickly throughout the room. Moreover, when the control plate is used to adjust the air outlet, 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. [0019] Furthermore, in the ventilating apparatus according to the present invention, 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. In this case, 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. Then, 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. Subsequently, the external air is blown slowly out of the air outlet in all directions, the air outlet being open along the wall surface. [0020] Further, preferably, a mixture of antibacterial, deodorant metal and titanium oxide with antibacterial, deodorant ceramic is attached to the sound absorbing material. In this case, while introduced external air is passing through the sound deadening cartridge, 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. [0021] Moreover, in the present invention, 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. Continue reading...
