BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ventilation fan for ventilation of indoor air forcedly installed in various industrial fields, and more particularly, To prevent breakage and deformation of the ventilator due to fire, and to prevent diffusion of flame and toxic gas due to fire to the outside.

BACKGROUND ART Generally, a ventilator (ventilator) is a mechanism for ventilating outside air in a room. A rotating blade such as a propeller or a blade is provided on a shaft of a motor that generates a driving force to induce a flow of air It is used to replace indoor air with outside air or to remove gas such as toxic gas in a specific area.

Such a fan is installed in a hole of a wall or a ceiling, and the fan is installed in a wall or ceiling hole that communicates with the outside air, and is variously used according to the installation type, the use purpose, the structure of the rotating blades, and the configuration of the motor.

An industrial ventilator is proposed in Korean Utility Model No. 20-0293652 as a ventilator according to the prior art. In Claim 1 of the present invention, a driving motor is supported and installed on the ventilator body by a fixing leg, And a protection net for protecting the rotary vane is installed on a rear surface side of the ventilator main body, wherein the protection net is formed by pressing an expanded metal in a predetermined shape And an outer peripheral surface of the outer peripheral surface of the outer peripheral surface of the outer peripheral surface is molded.

As another conventional technique, a ventilation system of a building has been proposed through Korean Utility Model No. 20-0165572. In claim 1, a ceiling board is installed inside the interior space, and air The air conditioner according to any one of claims 1 to 3, further comprising: an air inlet (33a) and an air outlet; a case having a rectangular tubular shape disposed on the ventilation passage side and a ventilation fan A backflow preventing damper coupled to an air outlet side of the ventilation fan to prevent backflow of air when the ventilation fan does not operate, and a backflow prevention damper connected to the air outlet side of the case so as to prevent flames from spreading from the ventilation passage to the ventilation fan side And a duct connecting the air inlet of the ventilation fan and the air outlet of the ceiling plate. .

However, in the ventilating apparatus according to the related art, it is desirable to design the size of the circular fire damper as large as possible for smooth air inflow. However, there is a problem that the degree of freedom of design design is reduced due to the circular shape of the fire damper. That is, since a circular fire damper must be installed in the case of a rectangular tube, there is a problem that it is difficult to efficiently design the case and the fire damper.

As another conventional technology, Korean Patent Publication No. 10-1413178 has proposed a blower having a shutter driven by wind pressure. In claim 1 of the present invention, A rotatably coupled device body; A plurality of shutters disposed at one opening of the main body adjacent to the fan; And a non-motion shutter rotation driving unit connected to the plurality of shutters and rotating the shutters in a non-dynamic manner such that one opening of the apparatus main body is opened or closed based on whether the fan is rotated or not, A lever to which one end of the lever is coupled to a rotary shaft forming a rotary axis of the shutter; And a weight plate connected to the other end of the lever, wherein each of the levers is provided for each of the shutters, and all of the levers are connected together to the weight plate member. The shutter is rotated counterclockwise And the lever is operated in a moment in which the weight plate rotates in the clockwise direction (the direction in which the shutter is closed) in the initial state in which the shutter is closed, Wherein when the shutter is opened by a predetermined angle or more, the weight plate is eccentrically arranged to act in a counterclockwise direction (a direction in which the shutter is opened), and when the rotation of the fan is stopped, And is configured to be closed by its own weight because it is actuated. A blower having a shutter is disclosed. In the blower having such a structure, the shutter is automatically rotated by the air flow rate by the blowing air to open the opening, and when the rotation of the fan is stopped, the shutter returns to its home position by its own weight, State.

However, since the ventilator or the blower having the fire damper or the shutter according to the related art opens the damper or the shutter by using the wind generated by the rotation of the fan, it is easily switched to the open state by the wind pressure generated in the fire There was an abandonment.

In order to solve such a problem, another prior art is proposed in Korean Patent Publication No. 10-1264862, which discloses an apparatus for blocking a fire zone damper using a thermal metal temperature fuse. In claim 1, An upper and lower blocking plate installed to be rotatable on upper and lower hinge shafts of the central portion and closing the fire damper; A solenoid installed above the outer surface of the front damper provided with the upper shield plate and electrically operated by the detection signal of the smoke detector; A support bar connected to one end of each of the upper and lower shield plates to guide the upper and lower shield plates when closing the inside of the fire fighting damper connection tube with respect to the upper and lower hinge shafts when the thermal fuse is separated; And a spring which is connected to a side end of the lower end blocking plate and pulls around the lower hinge axis to close the inside of the connecting pipe of the fire damper by the upper and lower blocking plates, wherein the solenoid moving shaft and one end And a temperature fuse which is connected to the other end of the upper connection member and is separated from the inner pipe by heat due to the heat of the separation or fire due to the smoke detector signal. The temperature fuse separating the outer pipe and the inner pipe has a hollow portion A base tube having one end closed and the other end open; A molten metal installed between the outer tube and the inner tube of the base tube so as to be melted at a predetermined temperature; A plurality of heat insulation fins are provided on the outer surface of the outer tube of the base tube at equal intervals to collect heat in the horizontal and vertical heat collectors to constitute a temperature fuse.

However, the fire-fighting zone damper breaking apparatus using the temperature-sensitive metal thermal fuse according to the prior art is not only complicated in structure, but also has a structure for interlocking with an expensive solenoid.
