The controller is connected to the temperature sensor 5 and the ion-type smoke sensor 6 respectively. When the temperature sensor 5 outside the car and/or the ion-type smoke sensor 6 detects a value exceeding the threshold, the controller triggers the fan 2 to turn forward and turn on the B Exit 22, when the value detected by the ion-type smoke sensor 6 in the car exceeds the threshold, the controller triggers the fan 2 to reverse to draw air and opens the A outlet 21, when neither the temperature sensor 5 nor the ion-type smoke sensor 6 exceeds the threshold, the controller Trigger the blower fan 2 to forward air supply and open the A outlet 21.

Described temperature sensor 5 and ion-type smoke sensor 6 are distributed in car 1 outer wall and outside car 1 door, when temperature sensor 5 detects high temperature then trigger alarm device 11, hoistway spray device 12 and ventilation device 13 start; Similar , when the ion-type smoke sensor 6 outside the car detects that there is smoke, it can also trigger the alarm device 11 and the hoistway sprinkler 12 to start. Whether the elevator is in a fire can be known by the temperature sensor 5 and the ion-type smoke sensor 6 .

Wherein, alarm device 11 is common sound and light alarm and alarm bell, and can notify the resident of each floor.

And well sprinkler 12 comprises water pump, water pipe 9 and shower nozzle 10, tap water is imported into water pipe 9 by water pump, water is transported to the top of well 8 along water pipe 9, and each floor is all provided with a shower nozzle 10, when fire danger occurs At this time, the well sprinkler 12 starts, the valve of the control nozzle 10 is opened, and water is sprayed into the well 8. On the one hand, the toxic gas soluble in water can be dropped to the side wall or bottom of the well 8 along with the water droplets, thereby reducing the amount of water in the well 8. The content of toxic gas in the air, on the other hand tap water can absorb the thermal energy in the shaft 8, play the effect of cooling. The hoistway spraying device 12 can reduce the impact of the dense smoke and high temperature caused by the fire on the environment of the car 1, thereby providing better living conditions and prolonging the rescue time.

The blower fan 2 that the ventilation device 13 of the existing elevator adopts generally only has the air supply function, but if the fire situation, the hoistway 8 has been full of smoke and dust mixed with various toxic gases, if the elevator continues to use the ventilation device 13 to carry out ventilation, then Toxic smoke and dust will be sucked into the car 1, and the purpose of preventing smoke cannot be achieved. If close this ventilator 13, then trapped personnel can cause along with the lapse of trapped time, the oxygen content in the air in the car 1 is less and less, can occur hypoxia, the problem of suffocation.

The fan 2 included in the ventilation device 13 in this embodiment is arranged above the car 1, and the fan 2 can rotate forward to supply air or reversely to draw air. The first tuyere 3 is provided with 1-10, respectively at the bottom of the car 1 bottom plate or side wall, and communicates with the air outside the car 1; it can be either an air inlet or an exhaust port, depending on the direction of rotation of the fan 2 depends. The second tuyere 4 is provided with 1-10, is located at the top in the car 1, and described second tuyere 4 is connected with blower fan 2 one end by air passage; is the exhaust port, depending on the direction of rotation of the blower fan 2.

Specifically, as shown in Figure 3, when the fan 2 is turning to supply air to the car 1, the air outside the car 1 enters the car 1 through the second air port 4, and then is discharged into the car from the first air port 3. 1 outside, forming air flow circulation, playing the role of ventilation, at this time the second air port 4 is the air inlet, and the first air port 3 is the exhaust port. When the fan 2 reverses to draw air in the car 1, the air in the car 1 is discharged out of the car 1 through the second tuyere 4 to form a negative pressure in the car 1, and the air pressure outside the car 1 is greater than that in the car 1. air pressure, the air outside the car 1 is replenished into the car 1 through the first air port 3, thereby forming an air flow cycle. At this time, the first air port 3 is an air inlet, and the second air port 4 is an exhaust port.

When the temperature sensor 5 and the ionic smoke sensor 6 trigger the alarm device 11 and the hoistway sprinkler 12 to start, they can also trigger the ventilation device 13 to start. At this time, the fan 2 opens the B outlet 22 of the fan 2 to make the fan 2 and the air filter 7 connected, and the fan 2 rotates in the forward direction to send air to the car 1, so that the air outside the car 1 first passes through the air filter device 7 and then enters the car 1, even if the air contains high concentrations of toxic fumes, it can Ensures that the filtered air meets the air quality requirements, thus solving the ventilation problem in the car 1 in case of fire.

However, in daily elevator use, the air in the well does not need to be filtered. If the air filter device 7 is also used in the daily elevator ventilation process, it will require high maintenance costs. This is because the air filter device 7 has adsorbed particles and toxic gases to a saturation value. After that, there is no filtering effect, so it needs to be replaced and cleaned regularly, resulting in high maintenance costs. For this reason, the fan 2 of the present invention is provided with two outlets: an A outlet 21 and a B outlet 22 , and the B outlet 22 communicates with the air filtering device 7 . Exit A 21 is directly connected with the outside air. For daily elevator ventilation, open Exit A 21, close Exit B 22, and directly collect the air in the shaft for ventilation; when a fire occurs, close Exit A 21, open Exit B 22, and ventilate the air in the hoistway. It is first filtered and then discharged into the car 1. Adopting the present invention not only solves the ventilation problem in the car 1 in case of fire, but also reduces the daily maintenance cost, and has strong compatibility with existing elevators.

Daily elevator ventilation will encounter two situations: (1) Someone is smoking in car 1, making it difficult to disperse the smell of smoke in car 1; (2) There is no peculiar smell. For the case (1), the car 1 of the present invention is equipped with an ion smoke sensor 6, which is a highly sensitive smoke detector. When the detected value exceeds the preset threshold, the fan 2 opens the A outlet 21 , close the B outlet 22, and the reverse draft will quickly extract the smoke-smelling air, thereby keeping the air in the car 1 fresh. For the case of (2), if there is no smoke smell, the ionic smoke sensor 6 in the car will not be triggered. The fan 2 still opens the A outlet 21 and closes the B outlet 22, but at this time it adopts the positive air supply mode. This way is more comfortable for the passengers.

Preferably, in the case of a fire, the main power supply of the elevator may be cut off. The automatic alarm rescue elevator of the present invention is also provided with a UPS uninterruptible power supply, a UPS uninterruptible power supply, a temperature sensor 5, an ion-type smoke sensor 6, and an alarm device 11. The hoistway spraying device 12 is connected to the ventilation device 13 for power supply.

It should be noted that the air filter device 7 of the present invention is provided with an ultrafine glass fiber filter layer, an activated carbon layer and a silver-loaded titanium dioxide layer. The air filter device 7 can filter particulate matter in the air and toxic gases such as carbon monoxide, carbon dioxide, benzene, toluene, sulfur dioxide and phosphorus pentoxide, which can meet the filtering requirements in case of fire.

In summary, the present invention judges whether it is in a fire situation through the temperature sensor and the ion smoke sensor, utilizes the forward and reverse rotation of the fan, the characteristics that the outlet of the fan A communicates with the external air, and the outlet of the fan B communicates with the air filter device to realize In the event of a fire, the air is filtered to ensure the quality of the air entering the car, and in daily situations, it is ventilated normally, which not only solves the ventilation problem in the car in case of a fire, but also keeps the car in good ventilation during daily use. Low maintenance costs. In addition, the present invention is also equipped with a well sprinkler 12, which can reduce the content of toxic gas and smoke in the air of the well in case of fire, and at the same time reduce the high temperature caused by fire.
