[Scope of Claim for Utility Model Registration] (1) This relates to an improved structure of an indoor ventilation device capable of preventing noise, which includes an improved outlet throat and an improved outlet throat at the air outlet of one indoor ventilation device. The features of the present invention are as follows: The outlet throat has an inclined wind pipe at a position corresponding to the air outlet of the indoor ventilation system. A hole is installed in the wall at the upper end of this hole, and a concave check valve is attached to the wall at the upper end of the hole to allow air to easily flow out of the room and prevent it from entering the room. The valve has a sealing cover over the entire hole due to its own weight; the curved wind pipe extends inward from the air inlet end and gradually expands, and after passing through the curve, it extends and gradually contracts to the air outlet end. With this, we have created a single airflow intake/conversion device, making the airflow discharge in a straight line, minimizing air resistance with this shape of curved wind pipe, and improving the noise caused by air vibration. It has been made possible. (2) Scope of Utility Model Registration Claims As stated in paragraph (1), an improved structure of an indoor ventilation device that can prevent noise,
Among them, the concave check valve installed in the outlet throat has a concave arc surface design, protruding outward in the outflow direction of the curved wind pipe and concave inward toward the indoor ventilation system. It is characterized by its shape.
