Title:
AUTOMATIC INSECT SCREEN OPENING/CLOSING DEVICE FOR VENTILATOR
Document Type and Number:
WIPO Patent Application WO/2021/206266
Kind Code:
A1
Abstract:
The present invention relates to an automatic insect screen opening/closing device for a ventilator, the device automatically opening an insect screen when a ventilator is operated, blocking the insect screen so as to prevent external insects from flowing therein if the ventilator stops operating, and having support plates formed at both sides of the insect screen in the vertical direction and having a horizontal bar formed at the lower end thereof, and thus deformation thereof such as flapping caused by external wind or being folded does not occur so that the inflow of the external insects can be blocked. The present invention comprises: a first winding roll, which is formed on the outer side of a ventilator used for buildings, industrial sites, or the like so that an insect screen is wound therearound, and which is formed above a discharge port of the ventilator so that the insect screen is unwound therefrom through rotation; the insect screen wound around the first winding roll so as to open/close a ventilator outlet; a first drive motor formed on one end of the first winding roll so as to rotate the first winding roll in only one direction; a second winding roll which is formed under the discharge port of the ventilator so as to be connected to the first winding roll by means of a connector, and around which the connector is wound so that the insect screen is unwound from the first winding roll so as to block the discharge port of the ventilator; a second drive motor formed on one side of the second winding roll so as to rotate the second winding roll only in the direction opposite to the rotational direction of the first drive motor; guide grooves formed inside an outlet case of the ventilator so that the outer side of the insect screen is guided therein; and the connector which connects the first winding roll and the second winding roll through gears respectively formed at the first winding roll and the second winding roll, and to which the insect screen is fixed so as to rotate, by means of the rotation of the first winding roll or the second winding roll, the second winding roll together with the first winding roll or the first winding roll together with the second winding roll, wherein the insect screen is opened by being wound around the first winding roll through the first drive motor when the ventilator operates, and the insect screen is closed by being unrolled toward the second winding roll by means of the driving of the second drive motor when ventilator stops operating.
