  As shown in FIG. 3, the escalator 50 includes a hollow deck 50 a having a truss structure as a base of the escalator 50. The deck 50a is installed between a building beam (not shown) arranged on the upper floor and a building beam (not shown) arranged on the lower floor, and the escalator 50 is installed. It supports the load and load capacity of each component. The deck 50 a is provided with a plurality of steps (not shown) connected in an endless manner, and the plurality of steps are circulated between the entrance and the exit of the escalator 50 by the drive motor 55. It has become. And a person and an object are conveyed by these several steps.

  A pair of balustrades 52 (only one balustrade 52 is shown in FIG. 3) are erected on both sides in the width direction of the deck 50a so as to face each other. Each balustrade 52 has a side plate 52a made of transparent glass. Each balustrade 52 is provided on the deck 50 a so as to continuously extend from the entrance side to the exit side of the escalator 50. A moving handrail 51 is provided on the peripheral edge of each balustrade 52 over the entire peripheral edge of each balustrade 52. A passage 50b through which each moving handrail 51 passes is formed below each balustrade 52 in the deck 50a. Each moving handrail 51 circulates between the entrance and exit of the escalator 50 in synchronization with a plurality of steps.

  A plurality of electrostatic atomizers 11 (six electrostatic atomizers 11 as an example in the figure) are arranged in the deck 50a. Each electrostatic atomizer 11 can discharge charged fine particle water M toward the movement path in the passage 50b of each moving handrail 51, and is arranged at a certain interval at a position adjacent to the movement path. ing. Furthermore, a plurality of electrostatic atomizers 11 (six electrostatic atomizers 11 as an example in the figure) are respectively arranged at a certain interval on the ceiling 53 located above the installation space K. Yes. The electrostatic atomizers 11 arranged on the ceiling portion 53 discharge the generated charged fine particle water M into the installation space K at the place where the electrostatic atomizer 11 is arranged.

  In the present embodiment, the discharge of the charged fine particle water M by each electrostatic atomizer 11 is performed in synchronization with the start of driving of the escalator 50. Specifically, when power is supplied from the power supply to the drive motor 55 to drive the drive motor 55, a signal indicating that power is supplied to the drive motor 55 is transmitted to the system control unit 41. The system control unit 41 that has received the signal transmits a command signal to the control unit 17 so as to turn on the high-voltage power supply circuit 13, and the control unit 17 that has received the command signal from the system control unit 41 receives the high-voltage power supply circuit 13. The power supply circuit 13 is turned on. Then, application of a voltage is started with respect to the discharge electrode 23, and discharge | release of the charged fine particle water M by each electrostatic atomizer 11 is performed.

  An unspecified number of people ride on the escalator 50 configured as described above, and unspecified people come into contact with the moving handrails 51 one after another. In addition, since various odors and allergen substances enter the installation space K where the escalator 50 on which an unspecified number of people ride is installed, these odors and allergen substances adhere to each moving handrail 51.

  Therefore, the system control unit 41 adjusts the discharge amount of the charged fine particle water M discharged from the electrostatic atomizer 11 according to the number of people estimated by the human sensor 61. For example, the system control unit 41 controls the electrostatic atomizer 11 such that the more the estimated number of persons is, the larger the amount of discharged charged particulate water M is. Then, since the discharge amount of the charged fine particle water M discharged from each electrostatic atomizer 11 is increased, the efficiency of each moving handrail 51 and the installation space K is increased by the action of the active species contained in the charged fine particle water M. Deodorization / sterilization and inactivation of allergen substances can be performed well.

  Further, the discharge of the charged fine particle water M by each electrostatic atomizer 11 is continuously performed until a predetermined time elapses after the driving of the escalator 50 is stopped. When a predetermined time has elapsed, the system control unit 41 transmits a command signal to the control unit 17 so as to turn off the high-voltage power supply circuit 13, and the control unit 17 that has received the command signal from the system control unit 41 The high voltage power supply circuit 13 is turned off. Then, the application of voltage to the discharge electrode 23 is interrupted, and the discharge of the charged fine particle water M by each electrostatic atomizer 11 ends.

Next, characteristic effects of the present embodiment will be described.
(1) On the deck 50a of the escalator 50, a plurality of electrostatic atomizers 11 that discharge the charged fine particle water M are installed, and the plurality of electrostatic atomizers 11 move in the passage 50b of each moving handrail 51. It arrange | positions in the position adjacent to a movement path | route so that the charged fine particle water M may be discharged | emitted toward a path | route. Therefore, the charged handrail 51 can clean the moving handrail 51 by deodorizing and sterilizing the moving handrail 51 and inactivating the allergen substance in a non-contact state with the moving handrail 51. Furthermore, the charged fine particle water M can be generated only by applying a high voltage to the discharge electrode 23. For this reason, in order to keep the moving handrail 51 clean, it is not necessary to continue supplying a disinfecting liquid such as iodine to the moving handrail 51, and the workability of the maintenance work for keeping the moving handrail 51 clean is improved. Can be improved.

  (2) In addition to the position adjacent to the movement path of the moving handrail 51, each electrostatic atomizer 11 is also disposed in the ceiling portion 53 located above the installation space K where the escalator 50 is installed. Therefore, since the charged fine particle water M is also released toward the installation space K, the moving handrail 51, the balustrade 52, the steps and the walls in the installation space K are also deodorized / sterilized and allergen substances are not discharged by the charged fine particle water M. Can be activated. Furthermore, the charged fine particle water M can be released to a person riding on the escalator 50, and the charged fine particle water M is attached to the hair or clothes of the person riding on the escalator 50 to deodorize and disinfect the bacteria. Alternatively, allergen substances can be inactivated.

  (3) Each electrostatic atomizer 11 is disposed at a position adjacent to the moving path so that the charged particulate water M can be discharged toward the moving path of the moving handrail 51 in the deck 50a. Therefore, when each moving handrail 51 passes through the passage 50b, each electrostatic atomizer 11 discharges the charged fine particle water M so that the discharged charged fine particle water M is filled in the deck 50a. The exposure effect on the moving handrail 51 is enhanced, and the charged fine particle water M can be intensively attached to each moving handrail 51. Therefore, it is possible to efficiently deodorize and sterilize or inactivate allergen substances with respect to the moving handrail 51 that is easily contacted by a large number of unspecified people and easily becomes unsanitary.

  (4) The system control unit 41 controls the electrostatic atomizer 11 to adjust the discharge amount of the charged fine particle water M released by the electrostatic atomizer 11 according to the number of people estimated by the human sensor 61. Control. Therefore, when it is estimated that the number of people is large and the dirt in the installation space K and the moving handrail 51 is large, a large amount of charged fine particle water M can be discharged into the installation space K and the moving handrail 51. On the other hand, when it can be estimated that the number of people is small and the dirt in the installation space K and the moving handrail 51 is small, and it is not necessary to discharge a large amount of charged particulate water M to the installation space K and the moving handrail 51, the charged particulate water. The amount of M released can be made small. As a result, it is possible to prevent the charged fine particle water M from being discharged unnecessarily in the installation space K and to the moving handrail 51, and furthermore, the voltage applied to the discharge electrode 23 is unnecessarily consumed. This can be prevented.

  (5) The discharge of the charged fine particle water M by each electrostatic atomizer 11 is performed in synchronization with the start of driving of the escalator 50. Therefore, when the escalator 50 is not driven and a person is not on the escalator 50, the charged fine particle water M is not discharged by each electrostatic atomizer 11, and the charged fine particle water M It is possible to prevent wasteful release.

  (6) The discharge of the charged fine particle water M by each electrostatic atomizer 11 is continuously performed until a predetermined time elapses after the driving of the escalator 50 is stopped. Therefore, even when odors, bacteria, and allergen substances are floating in the installation space K when the driving of the escalator 50 is stopped, the deodorizing / removal is performed by the charged fine particle water M released from the electrostatic atomizer 11. Inactivation of fungi and allergens can be performed.

  (7) In the present embodiment, by discharging the charged fine particle water M to the moving handrail 51, the moving handrail 51 can be cleaned in a non-contact state with respect to the moving handrail 51. Therefore, as in the prior art, when the dirt of the moving handrail 51 is removed by bringing the roller impregnated with iodine into direct contact with the moving handrail 51, the dirt from the moving handrail 51 accumulates on the roller and accumulates on the roller. It is possible to prevent the dirt from contaminating the moving handrail 51.

  (8) The electrostatic atomizer 11 includes a Peltier module 26. Therefore, since dew condensation water can be generated on the surface of the discharge electrode 23 by the cooling operation of the Peltier module 26, there is no need to separately provide a device for supplying water to the surface of the discharge electrode 23. Maintenance for generating can be facilitated.

In addition, you may change embodiment of this invention as follows.
In the embodiment, the system control unit 41 estimates the number of people in one area among the areas obtained by dividing the installation space K into a plurality of areas, and estimates the other areas as the same number of persons to the escalator 50. The number of people on board may be estimated.

  In the embodiment, the system control unit 41 estimates the number of people on the escalator 50 by estimating and totaling the number of people in each area of the installation space K divided into a plurality of areas. May be. And the system control part 41 controls the electrostatic atomizer 11 so that the discharge amount of the charged fine particle water M may be adjusted according to the estimated number of people. Even in this case, the charged fine particle water M can be efficiently discharged into the installation space K according to the number of people on the escalator 50.

  In the embodiment, the number of people on the escalator 50 may be estimated using a carbon dioxide sensor. The carbon dioxide sensor is preferably arranged at the center of the installation space K in order to detect the carbon dioxide concentration in the installation space K with high accuracy. Then, the detection result detected by the carbon dioxide sensor is output to the system control unit 41. The system control unit 41 determines the number of people on the escalator 50 based on the carbon dioxide concentration detected by the carbon dioxide sensor based on the relationship between the number of people on the escalator 50 and the carbon dioxide concentration in the installation space K. presume.

  In the embodiment, the number of people on the escalator 50 may be estimated using a weight sensor. The weight sensor detects a person's weight when the person gets on the step, and outputs a detection result detected by the weight sensor to the system control unit 41. The system control unit 41 estimates the number of people on the escalator 50 based on the relationship between the number of people on the escalator 50 and the total weight of the body weight detected by the weight sensor.

  -In embodiment, discharge | release of the charged fine particle water M by each electrostatic atomizer 11 may be performed in conjunction with the detection of the person by the human sensitive sensor 61. When receiving the detection signal of the human sensor 61, the system control unit 41 controls each electrostatic atomizer 11 so as to release the charged fine particle water M, and the reception of the detection signal from the human sensor 61 is interrupted. When it sag, each electrostatic atomizer 11 is controlled to stop the discharge of the charged fine particle water M. According to this, the charged fine particle water M can be discharged only when a person is on the escalator 50, and when the person is not on the escalator 50, It is possible to prevent the charged fine particle water M from being discharged unnecessarily without being discharged.

  In the embodiment, the discharge of the charged fine particle water M by each electrostatic atomizer 11 is continuously performed until a predetermined time elapses after the driving of the escalator 50 is stopped.

  In the embodiment, the system control unit 41 controls each electrostatic atomizer 11 so that the charged fine particle water M is released by each electrostatic atomizer 11 at a predetermined time. Also good. For example, the system control unit 41 includes a timer, and transmits a signal to the system control unit 41 when the timer reaches a predetermined time. The system control unit 41 that has received the signal from the timer controls each electrostatic atomizer 11 such that the charged fine particle water M is released by each electrostatic atomizer 11. Further, when a predetermined time elapses from the discharge start time of the charged particulate water M, the timer transmits a signal to the system control unit 41 again, and the system control unit 41 that has received the signal from the timer Each electrostatic atomizer 11 is controlled so that the discharge of the charged fine particle water M by the atomizer 11 is stopped. According to this, for example, it can be set to automatically discharge the charged fine particle water M by each electrostatic atomizer 11 for a certain period of time before the store opening time, and the installation space before the customer visits the store.

In the installation space K, the greater the number of people on the escalator 50, the greater the degree of contamination. Therefore, for example, the system control unit 41 controls the electrostatic atomizer 11 such that the discharge time of the charged fine particle water M becomes longer as the estimated number of people increases. Then, even if the degree of contamination in the installation space K is severe, the charged fine particle water M is continuously discharged over a long time, so that the installation space K can be efficiently cleaned.
