From the control unit 22 to the cleaning unit 4 is arranged.

  When all the call buttons of the hall 1 are not pressed and the destination button in the car 2 is not pressed, that is, when there is no press signal in the signal input from the control panel, the control unit 13 performs the brush motor 10. And the cleaning section motor 5 is operated to clean the car floor 3. Thereby, it is possible to clean the car floor 3 at a time when the elevator user is not sure, and to prevent the user from being troubled.

  The control unit 13 is connected to the side wall sensor 50 and the storage unit sensor 52 via the wiring 22. The side wall sensor 50 is provided on the second side wall 44 and detects that the cleaning unit 4 has reached the second side wall 44. This detection result is output from the side wall sensor 50 to the control unit 13. On the other hand, the storage unit sensor 52 is provided in the storage unit 46 and detects that the cleaning unit 4 has reached the storage unit 46. The detection result is output from the storage unit sensor 52 to the control unit 13. These sensors 50 and 52 have switches, such as limit switches, for detecting the arrival of the cleaning unit 4 by mechanical contact with the cleaning unit 4. However, the sensors 50 and 52 of the present embodiment are not limited to this configuration, and may be configured by a non-contact type magnetic sensor or an infrared sensor as long as the arrival of the cleaning unit 4 can be detected.

  If the signal which detected the arrival of the cleaning part 4 is input from the side wall sensor 50, the control part 13 will reverse the rotation of the motor 5 for cleaning parts, and will move the cleaning part 4 to the 1st side wall 42 side. Thereafter, when a signal that detects the arrival of the cleaning unit 4 is input from the storage unit sensor 52, the control unit 13 stops the cleaning unit motor 5 and the brush motor 10. With this control, the cleaning unit 4 can reciprocate between the first and second side walls 42 and 44 at the time of cleaning. However, the present embodiment is not limited to this configuration, and the cleaning unit 4 can be reciprocated between the first and second side walls 42 and 44 a plurality of times.

  Further, the control unit 13 is connected to the front wall drive unit 19 via the wiring 22. When the cleaning unit 4 moves from the storage unit 46 to the second side wall 44, the control unit 13 operates the front wall driving unit 19 to move the front wall 16 upward, and moves the cloth-like member 17 from the car floor 3. Isolate. Thereby, it is possible to prevent dust and dirt wiped off by the cloth-like member 17 from remaining on the car floor 3 near the second side wall 44. On the other hand, when the cleaning unit 4 moves from the second side wall 44 to the housing unit 46, the control unit 13 operates the front wall driving unit 19 to move the front wall 16 downward, and moves the cloth-like member 17 to the car floor. 3 is brought into contact. As a result, the dust that could not be swept out by the brush 11 and the dirt on the car floor 3 can be wiped off by the cloth-like member 17 and accumulated in the dust receiving portion 21.

  Next, operation | movement of the car floor cleaning apparatus of this embodiment is demonstrated. When there is no pressing signal of the calling button of the hall 1 and the destination floor button in the car 2, the control unit 13 determines that the elevator is not used and causes the cleaning unit 4 to start cleaning.
