In the emergency rescue operation apparatus for an elevator equipped with a control means, the control means, when the fire sensor detects a fire during the rescue operation in a fire, is a floor below a predetermined floor from the floor where the fire detector is detected. The floor is the top floor, and the floor below the top floor is the rescue floor and responds to a car call or a hall call.

  This invention responds to a car call or a hall call when a fire is detected, with the floor below the predetermined floor from the floor where the fire detector is detected as the top floor and the floor below the top floor as the rescue floor. Thus, the person left in the elevator hall can be rescued safely. That is, rescue passengers on safe rescue floors that can be rescued, and the floors detected by the fire detector and passengers on the upper floors that may be full of smoke are managers or firefighters, etc. It is possible to perform safe and reliable rescue activities.

  FIG. 1 is a hardware block diagram showing a configuration of an elevator fire rescue operation apparatus according to an embodiment of the present invention. The elevator rescue operation apparatus shown in FIG. 1 shows an example in which an elevator control panel is configured by a microcomputer, and the microcomputer 12 performs a control operation based on an input circuit 12a and a fire rescue operation program. A CPU 12b as means, a memory 12c for storing a rescue operation program in fire and various data, and an output circuit 12d are provided.

  Here, the input circuit 12a is provided in the car destination button 1 installed in the car, the hall button 3 installed in the hall, the monitoring room or the landing on the evacuation floor, and immediately calls the car back to the evacuation floor. Rescue operation switch 5 in case of fire for responding to car calls and landing calls, emergency operation switch provided in the car, for example, when operated by a firefighter, etc., to invalidate the landing call and respond only to the car call 6. Provided in each floor landing or in a hoistway corresponding to each floor, a signal from a fire detector 7 that emits an output when heat or smoke is detected is input.

  Further, the output circuit 12d is provided in the car or the landing, and is provided in the car 9 or the elevator, the indicator 9 for displaying the fire or the rescue operation to the passengers in the car or the elevator hall. An alarm 10 for notifying a user of a hall that a fire is in operation and a rescue operation, a drive control device for controlling a hoisting motor for running a car and controlling a door motor for opening and closing a door 11 is sent to the control output.

  FIG. 2 is a functional block diagram of the microcomputer 12 shown in FIG. As shown in FIG. 2, the microcomputer 12 shown in FIG. 1 makes a car call registration means 2 for registering a car call when the car destination button 1 is operated and a hall call when the hall button 3 is operated. By using the hall call registration means 4 to be registered, the car call, the hall call, the fire rescue operation switch 5, the emergency operation switch 6, and the fire detector 7 on each floor, the car is run, stopped, door open / close, indicator 9, and alarm. 10 and the control means 8 for controlling the drive control device 11. The control means 8 may include functions of the car call registration means 2 and the hall call registration means 4.

  FIG. 3 is a flowchart for explaining the control contents of the rescue operation during a fire by the control means 8. The operation will be described below with reference to the flowchart shown in FIG. First, when a fire occurs and the fire detector 7 is activated or the manager turns on the rescue operation switch 5 in case of a fire (step S1), the control means 8 is controlled by the display 9 and the alarm 10 in the car or the landing.
