Emergency escape elevator according to an embodiment of the present invention is operated so that disasters, especially in the event of a fire in the building during the disaster can quickly escape the building, the process will be described in detail below.

When a fire occurs in the building, disaster victims located in the lobby of the building or on each floor of the building press the select button 53a configured at the input unit 53 of the calling unit 51 installed on each floor to move the elevator car 11 to the selected floor. Call

At this time, when the selection button 53a configured at the input unit 53 of the calling unit 51 is pressed, the selection signal is input to the call signal control unit 54, and the call signal control unit 54 detects the input selection signal and calls the call signal. Generate and output to the call signal transmitter 55.

When a call signal is input to the call signal transmitter 55, the call signal transmitter 55 receives a call signal receiver of the control unit 31 that controls the driver 21 to drive the elevator car 11. A radio call is made to 33 to call the elevator car 11.

At this time, in an emergency such as a fire, the selection button 53a of the call unit 51 is urgently pressed in each floor, and the elevator car 11 is first moved to the selected floor.

When the call signal from the call unit 51 is received by the call signal receiver 33 of the controller 31 controlling the driver 21, the driver controller 34 electrically connected to the call signal receiver 33 receives the received call. The signal is sensed to control the driver 21.

That is, the drive controller 34 transfers the power supplied from the commercial power supply unit 32 to the drive motor 22 of the drive unit 21 to drive the drive motor 22, whereby the elevator car 11 is a building. Along the outer wall of the first move to the selected floor.

When the elevator car 11 first moves to the selected floor and stops, disaster victims located on the floor board the elevator car 11. At this time, the control unit 31 withdraws the footrest 13 provided to be accommodated in the elevator car 11 to the outside.

The disaster victims move through the windows of the building, step on the footrest 13 of the elevator car 11, and open the door 12 in a standing state to board the elevator car 11. At this time, since the elevator car 11 is provided with opening and closing doors 12 on all sides, disasters can quickly board through the opening and closing doors 12 on all sides.

As such, when the boarding of the disaster victims of the selected floor is completed, the elevator car 11 moves to the next selected floor, or when the elevator car 11 fills a garden, it moves to the ground floor.

The power controller 35 of the controller 31 continuously diagnoses whether the commercial power is continuously supplied or cut off from the commercial power supply 32.

On the other hand, when the fire is started and the disasters are boarding the elevator car 11, or while the disasters are boarding and moving, the cable connected to the commercial power supply 32 of the elevator car 11 will occur. Thus, commercial power supplied to the control unit 31 of the elevator car 11 is cut off.

When the commercial power supplied to the control unit 31 is cut off, the power controller 35 which is continuously diagnosing whether the commercial power is supplied or not detects the interruption sound of the commercial power and immediately issues an emergency power supply command for supplying emergency power immediately. The power is transferred to the charging unit 41.

When the emergency power supply command is transmitted to the emergency power charging unit 41, the charge / discharge control unit 44 controls to supply the power stored in the emergency power, that is, the storage battery 43 charging the electric energy produced by the solar light collecting plate 42. do.

At this time, the power stored in the battery 43 is output to the inverter 36 of the control unit 31, the inverter 36 converts the output DC power to AC power and transmits it to the emergency power supply 37.

In addition, the emergency power supply unit 37 supplies the transferred AC power to the driving unit controller 34 and the driving motor 22 of the driving unit 21, and the driving unit controller 34 is the driving motor 22 of the driving unit 21. Drive.

In this way, the elevator car 11 is immediately driven by the emergency power stored in the battery 43 even if the commercial power supplied is cut off, and continues to operate in the order of the selected floor by pressing the select button 53a of the calling unit 51. Conduct.

And when all the garden is filled in the elevator car 11, the disaster victim boarding the operating panel inside the elevator car 11 can operate directly to the ground floor.

The emergency escape elevator according to an embodiment of the present invention is provided with the opening and closing door 12 and the footrest 13 on all sides of the elevator car 11 so that the disaster in the building can be quickly boarded inside the elevator car 11 in case of fire And, by condensing solar heat to charge the emergency power and when the commercial power is cut off the emergency power in the fire can be quickly supplied to the drive unit 21 can continue the operation of the elevator car (11).

Even if the cable connected inside the building for supplying commercial power to the elevator car 1 is melted by a fire, emergency power can be supplied and operated immediately.

Therefore, it is possible to quickly rescue the disaster victims in the event of a fire, and even if commercial power is cut off by charging the emergency power charged by condensing solar light, it is possible to continuously rescue the disaster victims without interruption.

In addition, since the elevator car 1 is installed on the outer wall of the building, the elevator car 1 is installed and operated outside of the building, so that it may be safe from the danger of harmful gas generated in a fire, and thus may rescue the disaster victim very safely.

In particular, even if the cable connected inside the building for supplying commercial power to the elevator car 1 is melted by the fire can be supplied with emergency power immediately.

Hereinafter, an emergency escape elevator according to another embodiment of the present invention will be described with reference to FIG. 6 with the differences from the emergency escape elevator according to an embodiment of the present invention. Figure 6 is a block diagram showing the configuration of the call unit of the emergency escape elevator according to another embodiment of the present invention.
