FIG. 2 is a schematic view of a configuration of an air curtain apparatus according to an embodiment of the present invention, and FIG. 3 is a view for explaining an operation state of an air curtain apparatus according to an embodiment of the present invention.

2, the air curtain apparatus 200 includes an air accelerator 210, a sensor unit 220, a noise generating unit 230, first to third rotating units 240a, 240b and 240c, Three partitions 245a, 245b, and 245c, and a controller 250. [

The air accelerator 210 supplies air to be discharged through the first outlet 202 or the second outlet 204 formed in the air curtain apparatus 200, respectively. The air accelerator 210 includes a motor driven by the controller 250 and a control unit 250 for controlling the rotation of the motor so that the air sucked through an air inlet (not shown) And an impeller mounted to rotate in conjunction therewith.

The sensor unit 220 may include, for example, a sensor that senses smoke and / or heat to detect the occurrence of a fire. The sensor unit 220 provides a fire detection signal to the controller 250 when a fire is detected.

The noise generating unit 230 is provided in an area partitioned by the partition to allow air to flow through the air conveying port 206, and a silencer that generates noise by tube vibration generated when the introduced air passes .

The noise generating unit 230 may further include a centrifugal fan for supplying the air supplied by the air accelerator 210 to the silencer. The centrifugal fan may be arranged, for example, so that the air introduced through the air inlet formed in the central portion supplies air to the silencer at relatively high pressure by rotation of the centrifugal fan.

As shown in the figure, the air curtain apparatus 200 is provided with a first outlet 202 formed at a lower portion thereof for performing an air curtain function and a second outlet 202 formed at one side thereof for discharging air passing through the noise generating unit 230 204 are formed.

The first outlet 202 is coupled to one side of the first rotating part 240a and is opened or closed by a first partition 245a which rotates in conjunction with the rotating operation of the first rotating part 240a.

When it is necessary to perform the function of the air curtain in a normal situation, the controller 250 will rotate the first rotating portion 240a so that the first outlet 202 is opened. In order to prevent the generation of noise, the second rotating part 240b and the third rotating part 240c, which will be described later, are arranged such that the second partition 245b and the third partition 245c are located at positions where the corresponding air transfer path is closed Is rotated.

The second outlet 204 is connected to the third partition 245c or one side of the third rotation part 240c and is opened by the third partition 245c rotated in conjunction with the rotation operation of the third rotation part 240c Or closed.

An air conveyance port 206 for introducing air into the noise generating unit 230 is connected to one side of the second rotation part 240b and a second partition 245b which is rotated by the rotation operation of the second rotation part 240b ). ≪ / RTI >

In an emergency such as a fire or darkness, the controller 250 controls the air outlet 206 and the second outlet 204 to open so that the air passes through the noise generating unit 230 and generates noise. 2 and the third rotating parts 240b, 240c. At this time, the first rotary part 240a is positioned such that the first partition 245a is located at a position where the first discharge port 202 is closed so that the air supplied from the air accelerator 210 advances toward the noise generating unit 230 It can be rotated.

The first to third partitioning walls 245a, 245b and 245c are formed in a plate shape elongated in the longitudinal direction so as to conform to the shapes of the first and second discharge ports 202 and 204 and the like . In addition, when the first and second outlets 202 and 204 are formed in a plurality of holes formed spaced apart from each other, the first to third partitioning walls 245a, 245b, It is natural that it may be deformed into a shape.

The controller 250 controls the operation of the components provided in the air curtain apparatus 200.

For example, the controller 250 may control the air accelerator 210 to be driven or terminated by the control of the control system. The controller 250 also controls the rotation of the first rotating part 240a so that the first outlet 202 is opened for performing the air curtain function so that the air outlet 206 and the second outlet 204 are closed The rotation of the second and third rotating parts 240b and 240c can be controlled.

When the controller 250 receives a noise generation control command from the control system or receives a fire detection signal from the sensor unit 220, the controller 250 controls the first discharge port 202 while maintaining the operation of the air accelerator 210, And the rotation of the first to third rotation units 240a, 240b, and 240c may be controlled so that the air delivery port 206 and the second discharge port 204 are opened.

As described above, the air curtain apparatus 200 according to the present embodiment generates noise by the noise generation control command received from the control system even in the case of dark warnings generated in the middle of the night, thereby inducing safe escape of the personnel inside the building You may.

The air curtain device 200 is configured to supply the driving power to the air accelerator 210 and the controller 250 in order to enable the air curtain device 200 to perform a specified operation even when a building is electrostatically charged, A power storage power supply may be further provided.

Hereinafter, an operation state of the air curtain apparatus 200 will be briefly described with reference to FIG.

3 (a) shows a case where the air curtain device 200 performs an air curtain function in a normal situation, and FIG. 3 (b) shows an exit curtain function in an emergency situation such as fire or dark. As shown in Fig.

As shown in FIG. 3A, when the execution of the air curtain function is instructed from the control system, the air curtain apparatus 200 starts driving the air accelerator 210. The air curtain device 200 may also be configured such that the first discharge port 202 is opened and the first to third rotating parts 240a, 240b, and 240c are operated to close the air discharge port 206 and the second discharge port 204 .

Accordingly, air having a predetermined pressure and speed supplied from the air accelerator 210 can be discharged to the outside through the first outlet 202.

However, if a noise generation control command is received from a control system that recognizes a fire or darkness, or a fire detection signal is input from the sensor unit 220, The first discharge port 202 is closed while the accelerator 210 is driven and the first to third rotation parts 240a, 240b, and 240c are opened to open the air delivery port 206 and the second discharge port 204, As shown in Fig.

The air having a predetermined pressure and speed supplied from the air accelerator 210 flows into the noise generating unit 230 through the air conveying port 206 and flows into the noise generating unit 230 through the air In the course of passing through the silencer, noise is generated by the principle of tube vibration.

As described above, the air curtain apparatus 200 according to the present embodiment selectively activates the air curtain function or the noise generating function for guiding the outlet by opening or closing the outlet for discharging the air supplied by the air accelerator 210 As shown in Fig.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
