Description

OPEN AND SHUT DEVICE OF SMOKE VENTILATOR HAVING MANUAL MODE CONVERTING STRUCTURE OF BUTTON MANIPULATION TYPE, AND CONTROLLING METHOD FOR THE SAME

The present invention relates to a power switchgear for a smoke window, and more specifically, to a smoke ventilator installed in a building, for converting the power switchgear to a manual mode using a button operation method in an emergency, manual conversion of a button operation method It relates to a power switchgear for a smoke window having a structure and a control method therefor.

In general, a smoke window is one of the smoke facilities of a building, and is a facility for naturally discharging toxic gas generated during a fire to the outside of the building. These smoke windows should have a structure that can be opened automatically in response to a smoke detector or a heat detector (hereinafter referred to as a fire detector) in accordance with the relevant laws and regulations of the Building Act, and must also be able to open and close manually.

1 is a photograph illustrating a typical smoke window, and FIG. 2 is a view for explaining the concept of a general smoke window structure.

In the case of Korea, according to "Article 51, Paragraph ② of the Enforcement Decree of the Building Act," a smoke exhaust system for evacuating smoke in case of fire must be installed in buildings that are included in the designated use for buildings with 6 or more floors. The specific installation standards for these smoke exhaust facilities are stipulated in "Rule 14 of the Rules for Building Equipment Standards, etc.", and here, as shown in FIG. are doing Specifically, as the installation regulations for smoke windows presented in "Rule 14 of the Rules for Building Equipment Standards, etc.", the minimum area of a smoke window, a method for calculating the area of a smoke window, a vertical position for installation, and an opening method are suggested.

In addition, as shown in FIG. 2 , the smoke window in the current building is installed in a structure similar to that of the existing window, and when a fire occurs, it is automatically linked with the fire detection signal or in response to the smoke detection signal located around the smoke window. The design and installation are carried out in a structure with an open window.

On the other hand, when a fire occurs in a building, the fire detector detects the fire and transmits a fire detection signal to the smoke window, and the smoke window that recognizes the fire detection signal is automatically fully opened. Also, if the smoke window cannot be opened automatically in case of a fire, such as when the smoke detector fails to detect a fire due to a malfunction or the signal line between the smoke detector and the smoke window is disconnected, the occupant must manually open the smoke window completely.

At this time, when a fire detection signal is generated from the fire detector, a power opening/closing device is installed in the smoke window to automatically open the smoke window, and a manual opening/closing button (or opening button) is provided to manually open and close the smoke window. .

However, in the actual application process of the smoke window, there is an aspect that the window is usually used for ventilation purposes, so there are cases where the manual opening and closing function of the smoke window is used for ventilation of occupants rather than being used to completely open the smoke window in case of fire. That is, when the manual opening/closing button is pressed, the smoke window is opened at a predetermined opening angle instead of completely opened according to the user's intention for ventilation, or the smoke window is gradually opened only while the manual opening/closing button is pressed. Accordingly, due to the manual opening structure for ventilation in the smoke window, the original purpose of the smoke window, which should be quickly and completely opened in case of a fire, to smoothly discharge toxic gas, may be damaged.

In other words, in the event of a fire, if the smoke window cannot be opened automatically due to malfunction of the fire detector or signal line disconnection, the occupant must quickly and completely open the smoke window manually by pressing the manual open/close button. In the in state, there is a possibility that the smoke emission performance may decrease as the smoke window is opened at a desired opening angle rather than fully opened for ventilation or is gradually opened only when the manual opening/closing button (or opening button) is pressed.

Meanwhile, as a prior art, Korean Patent Registration No. 10-2189861 discloses an invention entitled "a smoke window opening/closing device that simultaneously controls two motors", which will be described with reference to FIGS. 3A and 3B.

And, the open switch 71 and the close switch 72 for detecting the open position and the closed position of the chain 63 are built-in, and inform the control unit 81 of the position of the chain 63 .

When the open signal of the smoke window 50 is input to the control unit 81 through the signal input unit 83, the motor 61 rotates the sprocket 62 forward to protrude the chain 63 from the drive box 60, At this time, the smoke window 50 is opened around the hinge 51 . And when the closing signal is input to the signal input unit 81, the chain 63 is pulled due to the reverse rotation of the motor 61 to enter the driving box 60, and the smoke window 50 is closed.

The smoke window to which the smoke window drive system according to the prior art is applied is provided with a power supply unit 84 for supplying power required for the operation of the motor 61 and the control unit 81 . And when an open signal or a close signal of the signal input unit 83 is input, the power of the power supply unit 84 is controlled step by step in a regulator resistance method, so that the initial opening and closing force of the smoke window 50 is opened or closed during opening or closing. A variable current control unit 85 for controlling the voltage current to be relatively large is provided.

The variable current control unit 85 controls the current in three stages at the initial opening or when the closing switch 72 is operated so that the amount of current supplied to the motor 61 is linearly increased or decreased to increase or decrease the motor 61 . As a result of the low-speed rotation of When opening and closing, it is natural that a relatively large force is required due to the weight of the smoke window 50 itself. Therefore, the variable current control unit 85 controls the amount of current supplied to the motor 61 so that the current is linearly increased or decreased at the initial stage of operation, so that there is no strain on the motor and smooth opening and closing is performed.

In addition, a display unit 82 notifying the operation state of the motor 61 and the presence or absence of an abnormality is provided, and the display unit 82 is composed of an LED lamp and is operated with a low current.

When the open operation signal of the signal input unit 83 is input to the control unit 81 by a wired or wireless method, the control unit 81 supplies power from the power supply unit 84 to the variable current control unit 85 .

The variable current control unit 85 linearly increases the current when the smoke window is initially opened by controlling the amount of current in three stages using the regulator resistance method to generate a large force from the motor 61 . In the middle of the smoke exhaust window 50 being opened, the inertial force acts so that the motor is not overloaded, so the motor is rotated at a constant speed to quickly open the smoke window. And when the smoke window 50 is completely opened, the open switch 7 ′ is operated. At this time, when an open signal is input to the control unit 8 ′, the variable current control unit 85 is controlled to reduce the amount of current linearly. 50) to make a smooth stop.

When the closing signal of the signal input unit 83 is input to the control unit 8 ′, power from the power supply unit 84 is supplied to the variable current control unit 85 to close the open smoke window 50 . Even in this case, the current supplied from the variable current controller 85 to the motor 61 is linearly increased so that the smoke window 50 is pulled, the current is kept constant during closing, and the closing switch 72 is operated. When the smoke window 50 is stopped, the current is linearly reduced to generate a large force from the motor 61 to close the smoke window 50 with a large force so that the packing installed between the smoke window 50 and the window frame is compressed. to ensure complete watertightness.

According to the smoke window driving system according to the prior art, it is possible to open and close the smoke window by distributing a large force at the initial stage of operation by linearly increasing or decreasing the amount of current supplied to the motor of the driving box for operating the smoke window. Accordingly, there is no strain on the motor at the beginning of operation, and during opening or closing, the motor is kept constant at a constant speed to realize quick opening and closing. It is possible to open and close the smoke window with an even force without distortion by maintaining a constant rotational speed of the motor.

On the other hand, as a prior art related to the manual switching structure of the power opening/closing device for a smoke window, Republic of Korea Patent No. 10-2124722 discloses an invention entitled "Manual switching structure of the opening/closing device of a sliding door for windows".
