  Hereinafter, the elevator 10 of the present invention will be described with reference to the drawings. In the following, the elevator 10 that operates one car 30 is illustrated, but the present invention can also be applied to an elevator that operates a plurality of cars by group management. In the following description, the side of the car door 31 that leads from the car 30 to the landing 21 will be referred to as the front of the car 30 as appropriate.

  FIG. 1 is an explanatory view showing an embodiment of the elevator 10. The elevator 10 includes a car 30 that can be moved up and down in a shaft 20 that connects between landings 21 provided on each floor of a building. In general, a machine room (not shown) is arranged on the top of the shaft 20, and an elevator control device 40 (see FIG. 2) that controls a driving mechanism such as a hoisting machine that raises and lowers the car 30 and traveling of the car 30 and the like. Is installed.

  A landing-side door 22 that opens and closes following the car-side door 31 is installed at the landing 21.

  The car 30 is a housing on which a user gets on, and a car-side door 31 is attached to the opening. In the car 30, a car control device 41 is disposed on the upper surface of the top plate 32. The car control device 41 is connected to the elevator control device 40, and controls the opening and closing of the car side door 31, the operation panel in the car, lighting, air conditioning, and the like. Various electric / electronic devices arranged in the car 30 are collectively referred to as an electronic device 42.

  As shown in FIG. 1 and FIG. 3, the car 30 has a water drop detection means 50 (hereinafter referred to as “car drop detection means” as appropriate) disposed on the top surface of the top plate 32. More specifically, the water drop detection means 50 on the car is disposed on the front side of the car 30 above the car-side door 31 so that water flowing into the shaft 20 from the floor surface of the landing 21 can be detected. As the car water drop detection means 50, one capable of detecting a small amount of water drops can be adopted, and the detection surface is arranged to face upward. A so-called rain sensor such as a comb-shaped electrode sensor can be exemplified as the water drop detecting means 50 on the car, and the resistance value is changed by the water droplets adhering between the electrodes arranged in a comb shape, so that water can be detected. For example, AKI-1805 (comb electrode sensor with heater) manufactured by Aszac Co., Ltd. may be employed as the water drop detection means 50 for the car in order to prevent early recovery after water detection or malfunction due to humidity. Yes, but not limited to this. For example, a camera that detects water droplets, a rain light sensor that detects water droplets by a light reflection method using a light emitting element and a light receiving element, or a water pressure sensor may be employed as the water drop detecting means 50 on the car.

  In addition, as shown in FIGS. 1 and 4, the car 30 has a water drop detection means 60 (hereinafter also referred to as “car lower water drop detection means” as appropriate) below the car side sill 33 which is the threshold of the car side door 31. Is arranged. The car lower water drop detection means 60 can use the same sensor as the car upper water drop detection means 50. In the case where the drainage hole 34 is provided in the car-side sill 33, it is desirable that the car lower water droplet detection means 60 be provided immediately below the drainage hole 34. Further, the car sewage water droplet detection means 60 can be arranged so as to jump out from the car side sill 33 to the landing side.

  As shown in FIG. 2, the car upper water droplet detection means 50 and the car lower water drop detection means 60 are electrically connected to the car control device 41, and when sensing water, the car control device converts the change in resistance value as a current change. 41.

  The water drop detection means 70 (hereinafter referred to as “landing water drop detection means” as appropriate) may also be arranged at the landing 21. In this case, for example, the landing water droplet detection means 70 may be disposed immediately below the drainage hole 24 of the landing side sill 23 or jump out to the landing side from the landing side sill 23. The landing water droplet detection means 70 is electrically connected to the elevator control device 40 as shown in FIG.

  As shown in FIG. 1, a damper 29 is provided in the pit 28 at the lower end of the shaft 20, and a water immersion sensor 80 for detecting water intrusion into the pit 28 is disposed. As the water immersion sensor 80, a float sensor can be exemplified. The inundation sensor 80 is electrically connected to the elevator control device 40 as shown in FIG.

  In the general operation of the elevator 10 having the above-described configuration, the car 30 travels in the shaft 20 by the operation of the operation panel of the car 30 or the landing 21, and responds to the car call or the hall call at a predetermined landing 21. Stop and open and close the doors 22 and 31.

  If water flows into the shaft 20 due to rain or water leakage in the vicinity of the landing 21, the car 30 may get wet, and the electronic equipment 42 of the car 30 may be poorly insulated or malfunction, and the car 30 may be corroded. There is. Therefore, in the present invention, the water droplet detection means 50, 60, 70 and the inundation sensor 80 are arranged, and when any sensor senses water exposure, the elevator 10 is operated to be subject to water control.

  Specifically, when the car water droplet detection means 50 or the car water drop detection means 60 senses water exposure, the car control device 41 transmits a water exposure signal to the elevator control device 40. Further, when the landing water droplet detection means 70 or the inundation sensor 80 senses water exposure, these sensors transmit a water exposure signal to the elevator control device 40. When the elevator control device 40 receives the flood signal, the elevator control device 40 shifts to a flood control operation. In the water-controlled operation, the elevator control device 40 stops at the nearest floor when the passenger is in the car 30 and opens and closes the doors 22 and 31, and after getting off the passenger, goes straight to the evacuation floor. The operation of the elevator 10 is suspended. The evacuation floor can be the floor with the lowest possibility of being flooded, for example, the top floor. Thereby, the moisture of the cage | basket | car 30 can be reduced as much as possible, the insulation failure of the electronic device 42 of the cage | basket 30 and a malfunctioning, the corrosion of the cage | basket | car 30, etc. can be suppressed, and the replacement frequency of defective parts can also be reduced. Moreover, since the time of a drying process can also be shortened by suppressing the flooding of the cage | basket | car 30, the time required for the restoration of the elevator 10 can also be shortened. It should be noted that the water-controlled operation can be returned to normal operation by inspection by a maintenance worker, remote operation, or the like.

  In the present invention, the water droplet detection means 50 and 60 are arranged on the car 30, so that it is possible to directly sense the water on the car 30. In addition, since the water droplet detection means 50 and 60 can detect a very small amount of water compared to a submersion sensor or the like, the water drop detection means 50 and 60 can detect water in the car 30 at an early stage and can move to a water-controlled operation. There is.

  In the water-controlled operation of the elevator 10, when the top floor is an evacuation floor, it is difficult to suppress the intrusion of water flowing into the car 30 from the top floor landing. For this reason, as shown in FIG. 5, it is preferable to set the evacuation position during the water-controlled operation of the car 30 to a position C higher than the floor level 26 of the landing on the top floor. For example, the evacuation position of the car 30 can exemplify a position where the floor level 35 of the car 30 is 50 to 100 mm above the floor level 26 of the top floor. This position can be set as an evacuation position without adding a switch or the like by using an upper limit switch (limit switch: not shown) used for inspection or emergency.

  By evacuating the car 30 at a position C higher than the floor level 26 on the top floor, the flow of water from the landing on the top floor to the car 30 is suppressed as much as possible. Defects and corrosion of the car 30 are effectively suppressed.

  In the present invention, the car water droplet detection means 50 is disposed on the top plate 32 of the car 30. Thereby, it is possible to respond early to water flowing into the shaft 20 on the upper floor than the car 30.

  Further, the car lower water drop detection means 60 and the landing water drop detection means 70 can detect the flow of water from the landing 21 to the car 30 at an early stage. In particular, the car sewage water drop detection means 60 has an advantage that it can be detected even when a beverage or the like is spilled in the car 30 or when it is wetted during cleaning.

  FIG. 6 shows an embodiment of a car 30 that can detect water on the top plate 32 at an earlier stage. As shown in the figure, the water guide means 51 is arranged on the top plate 32 along the front surface of the car 30. The water guiding means 51 collects a part of the water that has flowed into the top board 32, and can include, for example, a trout. The dredging that is the water guiding means 51 is installed with a gradient by one of the pillars 53 or the like toward one or an appropriate place, and the water collecting port 52 is provided at the lowest position. The water drop detection means 50 is disposed at the water collection port 52 so that the water collected at the water collection port 52 can be sensed. According to the present embodiment, it is possible to effectively sense water coverage on a wider range of the top plate 32 of the car 30.

  In the above embodiment, the water droplet detecting means is disposed under the top plate 32 of the car 30 and the bottom of the car, respectively, but the car side sill 33 is also provided with a hook serving as the water guiding means, and the water guiding means shown in FIG. It is also possible to connect the water collecting port 52 of 51 and the cage side sill 33 to detect water by one water drop detecting means at the water collecting position.

  Further, when a water drop detection camera or rain light sensor is used as the car water drop detection means 50, as shown in FIG. It is also possible to adopt a configuration in which a receiver is disposed and the car water droplet detection means 50 is mounted behind these rain receivers. The car water droplet detection means 50 can detect water on the car 30 by detecting water droplets attached to the rain receiver from the back side.

  The above description is for explaining the present invention, and should not be construed as limiting the invention described in the claims or limiting the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical scope described in the claims.

  For example, the sensor on the car that senses water is desirably water droplet detection means, but the sensor under the car and the landing sensor may be detection means such as a submersion sensor and a running water sensor.
