Abstract:
The objective of the present invention is to provide an automatic door with an air curtain by installing an air curtain in the upper part of a general entranceway instead of a door, multiple sensors using a photoelectric effect being formed at the front and rear sides of the upper part of the general entranceway, and by forming a controller which prevents air blast by recognizing only the part of the air curtain in contact with the body of a person, when the person enters or exits through the air curtain, by using a photoelectric effect or using an infrared sensor, a motion detecting (detecting movements of an object or a person) sensor, and a sensor used for an automatic door, wherein the controller prevents air blast with a motor, a pneumatic spring return type actuator, etc. when current flows at the detecting sensor, so that a person can freely enter and exit without being affected by a high pressure air blast of the air curtain.
