Ventilator

Abstract

The present invention relates to improvements in a ventilating apparatus installed in a ventilating hole in an outer wall to enable natural ventilation. The ventilating apparatus includes a sound deadening cartridge (10) installed in a ventilating hole (2) and a cap cover (20) detachably installed in an interior opening of the ventilating hole (2) and covering the sound deadening cartridge (10) and thus the interior opening of the ventilating hole (2), the cap cover (20) having an air outlet (24) through which introduced external air having passed through the sound deadening cartridge (10) is blown out into a room (4). The air outlet (24) is placed along a wall surface (8) to allow the introduced external air to flow out along the wall surface (8). The air outlet (24) may have a normally open portion (32) and an adjustment area (33) in which a control plate (30) is placed, the control plate opening and closing a part of the air outlet (24) so that the amount of air introduced can be controlled. Alternatively, the air outlet (24) may be normally open in all directions.

Description

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 stainl...

AI Technical Summary

Benefits of technology

"The present invention provides a ventilating apparatus for buildings that allows natural ventilation while also providing a comfortable and decorative appearance. The apparatus includes a sound deadening cartridge and a cap cover with an air outlet that can be placed over the ventilating hole. The cap cover has a mounting base that can be attached to the ventilating hole and a front cover that can be easily replaced. The apparatus also allows for adjustment of the air outlet to control the amount of air introduced and the direction in which the air flows. The cap cover can be attached to the front cover, allowing for easy decoration. The apparatus provides sufficient natural ventilation for at least 24 hours a day and does not expose people or objects to the external air. The sound deadening cartridge removes dust and pollen from the air and also acts as a filter to prevent these materials from entering the room."

Problems solved by technology

However, since the ventilating hole is a through-hole, external noise enters the room as it is unless certain sound insulating measures are taken.

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.

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.

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.

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.

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.
