Abstract

PROBLEM TO BE SOLVED: To provide a passenger conveyer suited for setting up in a skiing ground by preventing dew condensation. SOLUTION: A blower device 7 set up on the side of one machine room 1a of a passenger conveyer 1 to feed dried air along an oil pan 5 and a ventilator device 8 set up on the side of the other machine room 1b of the passenger conveyer 1 to discharge air in the other machine room 1b and air coming to be fed by the blower device 7 to the outside are provided. The blower device 7 and the ventilator device 8 are operated for a fixed time after stopping an electric motor 4 serving as a drive source moving a footstep 2, so that dew condensation prevention can be attained.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and an automatic line suitable for installation at a ski resort.

[0002]

2. Description of the Related Art Generally, in a passenger conveyor, when installed on a ski slope, a motor as a drive source for moving the steps becomes hot during operation. Dew condensation occurs on the drive chain and the like.

[0003]

The above-mentioned conventional passenger conveyor has a problem that a large amount of rust is generated in a short time, particularly in an electric motor and a step chain, due to condensation in winter.

An object of the present invention is to provide a passenger conveyor that can solve the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a motor having a plurality of endlessly connected steps, a step chain connecting the steps, and a driving source for rotating the steps to move the steps. And a passenger conveyer installed in a building with an oil pan disposed below the steps, and installed on one machine room side of the passenger conveyer and dried along the oil pan. An air blower for sending air, and a ventilator installed on the other machine room side of the passenger conveyor for discharging air in the other machine room and air sent by the blower to the outside, Is achieved by operating the blower and the ventilator for a certain period of time after stopping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a passenger conveyor comprises a number of steps 2 connected endlessly, a step chain 3 connecting these steps, and a drive source for rotating the step chains 3 to move the steps 2. An electric motor 4 and an oil pan 5 disposed below the steps 2 are provided between a first floor 6a and a second floor 6b of a building 6 of a ski resort.

An air blower 7 is provided in one machine room of the passenger conveyor 1, for example, a lower machine room 1a. A ventilation device 8 is provided in the other machine room of the passenger conveyor 1, for example, the upper machine room 1b. Ventilation device 8
Is connected to a duct 9 for guiding air from the ventilation device 8 to the outside of the building 6. The air sent from the blower 7 is dried and the oil pan 5
And flows toward the upper machine room 1b. The ventilation device 8 discharges the air in the upper machine room 1b and the air sent from the blower 7 to the outside of the building 6 through the duct 9. During the operation of the passenger conveyor 1, in other words, during the rotation of the electric motor 4, the blower 7 and the ventilator 8 are stopped without operating. When the electric motor 4 is stopped at midnight or the like, the blower 7 and the ventilator 8 start operating. Then, after a certain period of time, that is, usually about three hours, the blower 7 and the ventilator 8 are stopped. When the air blower 7 and the ventilator 8 are operated, a notification means, for example, the notification device 10 provided near the entrance of the passenger conveyor 1, for example, displays or broadcasts that "the dew condensation prevention operation is being performed". The display or broadcast indicating that “condensation prevention operation is being performed” by the notification device 10 is transmitted to the blower 7.
And during the operation of the ventilation system. During the dew condensation prevention operation, since the air from the blower 7 is efficiently sent into the upper machine room 1b, the entire outer periphery of the passenger conveyor 1 may be covered with a vinyl sheet.

In the above configuration, while the electric motor 4 is rotating, the electric motor 4 is maintained at a high temperature.
Etc. do not condense. When the electric motor 4 stops, the temperature of the electric motor 4 starts to decrease, but the blower 7 and the ventilation device 8 are operated, and the periphery of the step 2 and the step chain 3A, and the inside of the lower machine room 1a and the upper machine room 1b, The humid air is discharged out of the building 6 through the duct 9. Therefore, the insides of the lower machine room 1a and the upper machine room 1b and the periphery of the steps 2 and the step chains 3 are filled with the dry air, so that dew condensation on the electric motor 4, the step chains 3A and the chains 3 is prevented. The generation of rust is suppressed.

Although the passenger conveyor shown in FIG. 1 is an example of an escalator, the present invention is not limited to this, and the same effect can be obtained even when applied to an automatic line.

[0011]

As described above, according to the present invention, it is possible to prevent the occurrence of dew condensation after stopping the operation, and to obtain a passenger conveyor suitable for installation at a ski resort.
