Toilet door cylinder opening device for smoke exhaust}

The present invention relates to a toilet door cylinder opening device for exhausting smoke.

Typically, high-rise residential buildings such as apartments have a smoke control area in front of the front door of each unit, consisting of a special evacuation staircase and a room attached to the special evacuation staircase. When a fire breaks out within the unit, the smoke generated at the same time as the fire flows into the smoke control area where the evacuation staircase is provided. Smoke control equipment is installed to increase the air pressure in the smoke control area to prevent smoke from coming out.

However, as smoke and toxic gases are generated by a fire within a household, inhalation of the smoke and toxic gases can cause lung damage and cause residents to become unconscious or lose consciousness, preventing them from escaping from the household through the above-mentioned escape stairs or their attached rooms. It can also make things difficult.

From 2014 to 2018, the number of fires in apartment complexes was approximately 24,000, and the number of deaths was reported to be 285, so there is a need to focus on safety devices that consider maximum cost-effectiveness to prevent suffocation accidents.

The evacuation space of existing apartments uses a pressurized smoke control or smoke control system to suppress the inflow of smoke, but there is no mention of smoke emissions within the unit due to a fire.

Therefore, there is no smoke control or smoke control plan in the household where the fire occurred, so there is a high risk of suffocation accidents, and in the event of a fire, a smoke control damper (F.D) installed inside the ventilation duct connected to the vertical duct is installed to prevent the spread of smoke as it is designated as a fire prevention zone. “CLOSED” is regulated so that smoke inside the household cannot be discharged to the outside.

In other words, since the front door of apartment units is installed with a class A fire door, smoke dampers are installed to prevent flames and smoke generated within the unit from spreading to other units as they are designated as fire prevention zones. In the household where the fire broke out, the smoke dampers installed in the bathroom and kitchen hoods connected to the outside are in the “CLOSED” state, preventing the smoke inside the household from spreading to the outside.

Therefore, in the past, when a fire breaks out in an apartment complex, there is a problem that there is no way to exhaust the flame or smoke as the unit is designated as a fire prevention zone.
