Description

Automatic window opening and closing device having a PCB opening {Automatic Window Open and close Device with PCB In and Out Opening Part}

The present invention relates to a window opening and closing device having a PCB entrance opening, and specifically, when repairing or replacing a PCB used for a smoke exhaust window or an automatic closing device, the PCB inside the housing can be repaired more simply and conveniently, and the housing It relates to a window opening/closing device having a PCB entrance opening with an improved structure so that time for repairs can be reduced by not separating a window from a structure such as a window.

When a fire breaks out in an apartment or high-rise building, a large amount of smoke is generated due to combustion of indoor furniture or interior materials. Since such smoke contains toxic gas, most human damage caused by fire is due to suffocation due to smoke containing toxic gas rather than damage caused by heat.

In other words, when a fire occurs, smoke containing a large amount of toxic gas is instantaneously generated, and as this toxic smoke flows out into the evacuation route, it is difficult to evacuate through the evacuation route, resulting in many casualties, as well as fire suppression and loss of life. Rescue operations can be seriously disrupted.

Therefore, in apartments, etc., a ventilation area (front room) is provided in accordance with relevant laws and regulations to block the propagation of smoke generated in the event of a fire to the entire building.

Normally, when a fire occurs, the doors and windows of the smoke control area are automatically closed, and fresh air from the outside is introduced into the smoke control area to increase the air pressure in the smoke control area compared to the air pressure at the place where the fire occurred. Accordingly, it is possible to secure an evacuation route or passage by preventing toxic gases including smoke from flowing into the control area.

A window opening/closing device that is normally open to ventilate the outside and the smoke-reducing area and automatically opens and closes the window to block the outside and the smoke-reducing area so that it is closed in case of fire, and allows outside air to flow in in the event of a fire. It is provided with an air supply unit that opens the passage and increases the internal pressure of the control area, a fire door installed between each household and the evacuation stairs, and a control unit that automatically controls the operation of these various devices or mechanisms.

With this configuration, when a fire occurrence is detected by a sensor or the like in any one of the apartments, etc., the control unit closes the window and supplies air from the outside through the air supply unit to increase the internal pressure of the control area. Control the front room created between the fire area and the evacuation stairs to maintain the function as a control area by closing the use door.

That is, when a fire occurs in the indoor space, the smoke control area is formed in a closed state and the internal pressure of the smoke control area is raised to a certain pressure (eg, 40 Pa to 60 Pa) or more by the air supply action of the air supply unit. Accordingly, it is possible to prevent toxic gas generated by a fire in the indoor space from flowing into the smoke control area and the evacuation stairway.

And, one example of such a window opening and closing device is Registered Utility Model Registration No. 20-0215954 (2000. 12. 27), and the housing of the prior art includes a long bar-shaped square shape formed integrally by extrusion.

The housing for such a window opening/closing device is extruded in a rectangular shape, and various processes must be performed to form an opening through which a chain penetrating the housing enters and exits. That is, after extrusion, the process of milling an opening penetrating through the side of the square is required.

And recently, as the interior appearance of apartments, studios, officetels, etc. is valued, the smoke window opening and closing device, which is an essential facility in case of fire, is manufactured to a length that fits the window frame as much as possible so that there is no protruding from the window frame or empty space. tend not to.

Although a rather large number of parts are used in the window opening and closing device, as it has recently been equipped with an automation function, a motor is driven, a sensor that automatically detects the closed position, a sensor that automatically detects the open position, and a fire signal is received from the control room. In order to drive and control circuits that control doors to open or close, circuits that send signals to the control room in closed or open positions, automatic and manual operation circuits, etc., PCB boards are required for control units.

In addition, when such a PCB board is broken or deteriorated, the PCB board must be disassembled and reassembled from the device for repair or replacement.

In order to carry out this process, the end of the chain coupled to the door or window is disassembled from the door handle, etc., the housing is separated from the structure such as the window frame, the device inside the housing is separated from the housing, and the PCB board inside the device is replaced, It should be repaired. After repair, it is very complicated and time-consuming to combine the device into the housing in the reverse order of disassembly, then combine the housing with the window frame again, and combine the chain with the window.

The attachment and detachment process of the PCB substrate 3500 of the window opening and closing device 3000 according to the present invention and the prior art will be described in detail with reference to FIGS. 4A to 4C.

If the drawing numbers describing the configuration of the prior art are different in thousand units and the same in hundreds, tens, and units, it is assumed that they are the same as those of the present bag corresponding to hundreds, tens, and units unless otherwise specified. For example, the housing of the present invention is '1200' and the housing of the prior art is '3200'.

First, as shown in FIG. 4A, the conventional window closing device 3000 has no PCB opening of the present invention, so the housing 3200 must be separated from the structure including the window frame 10. The reason is that the housing 3200 is coupled to the length of the window frame 10 to which the window 20 is coupled for aesthetics, so it is coupled to the inside of the housing 3200 and is smaller than the length of the housing 3200 but somewhat longer. In order to take the mechanical unit 3100 of the form to the outside, the housing 3200 must be separated from the window frame 10. In general, the housing 3200 is combined so as not to protrude as much as possible into the recessed area (place, part) of the window frame 10 that does not protrude from the building structure including the wall, and the window frame 10 is not thicker than the building structure. Common.

Of course, in this process, the chain is separated from the window (20).

Next, as shown in FIG. 4B, in order to separate the mechanical unit 3100 from the housing 3200 separated from the windows 10, the user applies an external force to the mechanical unit 3100 in the longitudinal direction of the housing 3200. and take it outside.

Then, as shown in FIG. 4C , the PCB substrate 3500 coupled to the mechanical unit 3100 may be separated from the casing 3140 to be repaired or replaced.

After repair or replacement of the PCB board 3500, the mechanical unit 3100 is coupled to the mechanical unit 3100, the mechanical unit 3100 is coupled to the housing 3200, and finally the housing 3200 is coupled to the window frame 10 as described above. 4A, 4B, and 4C are performed in reverse order.

In the process of attaching and detaching the conventional mechanical unit 3100 from the housing 3200, there is a risk that an electric wire for supplying electricity or electromagnetic signals connected to the PCB substrate 3500 may be pinched or contacted between the housing 1200.

Comparing the replacement and repair processes of the PCB substrates 1500 and 3500 in these two designs, it can be seen that the process according to the present invention is much simpler, more convenient, and takes less time, so the economics can be greatly improved.

Accordingly, according to the present invention, the PCB board of the mechanical unit that automatically and operably controls the inside of the housing coupled to the structure including the window frame is formed in the housing without separating the housing from the structure to open the PCB substrate to the mechanical unit. It is possible to provide a window opening and closing device that can be simply and conveniently detached from.

In addition, it is possible to provide a window opening/closing device capable of reducing time and economical costs when replacing or repairing a PCB board of a mechanical unit.

Here, an embodiment of the present invention has been illustrated and described, but those skilled in the art with ordinary knowledge in the art to which the present invention belongs will be able to know that the present embodiment can be modified without departing from the principles or spirit of the present invention. . The scope of the invention will be defined by the appended claims and their equivalents.
