Abstract

PURPOSE:To enable protection of an elevator from entrance of water without operation by a worker by a method wherein entrance of water to an elevator is detected, and according to entrance of water, the position of a cage and an operation format are decided by an operation control means, and automatic protection operation is effected. CONSTITUTION:It is decided by a waterdrop detecting means 3 whether or not waterdrops are detected by a waterdrop detector 1, and when waterdrops are detected, it is decided whether or not a waterdrop amount exceeds a specified value. If it exceeds the specified value, it is decided whether or not a detecting signal from a water amount detector 2 is inputted to a water amount detecting means 4. In this case, if entrance of water to a bit 19 is confirmed, it is decided whether or not a water entrance amount exceeds a specified value, and when it exceeds the specified value, a cage is moved to a topmost floor, and it is decided by a cage operation deciding means 5 that operation of an elevator is suspended until a water entrance state is released. At a point of time when, after a waterdrop amount exceeding the specified valve is detected, no water drop is detected by the waterdrop detector 1, an elevator is returned to a usual service.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an elevator operating device that detects water intrusion into an elevator system and operates the elevator to protect it from water based on the detection result.

[Conventional technology]

If water floods into the pit of an elevator system, if the level of water intrusion increases, there is a risk that the end point switch inside the bit will be destroyed, and it is unsafe to operate the elevator using this destroyed equipment. Ru. Additionally, if the cage is operated on a bit that is submerged in water, the cage itself will suffer some damage.

Therefore, in order to prevent the above-mentioned adverse effects from flooding from affecting the elevator equipment, if there is a possibility that water may flood into the pit, the elevator should be moved to the top floor and elevator users should be instructed not to use the elevator. Or, elevator users themselves judged the possibility of flooding before moving the car. [Problems to be Solved by the Invention] As described above, the conventional elevator operation device does not rely on human judgment by elevator users or elevator managers to start the elevator protective operation against flooding in the pit. Because this was done in the same manner as before, there were problems such as errors in judgment or the absence of a protective driver, which could result in water seeping into the bit and damaging the elevator equipment. In addition, especially with home elevators, the platform is sometimes installed outside the house, like a garage, so there are many opportunities to get wet, and there is no caretaker, making it easy to forget how to operate the elevator. In addition, there was a problem in that having elderly people or people with disabilities take the trouble to operate the elevator made using the elevator inconvenient. This invention was made to solve the above-mentioned problems, and its purpose is to provide an elevator operating device that can perform protective operation of an elevator without requiring manual operation. [Means for Solving Problem H] The elevator operating device according to the present invention includes a water level detector that detects a minute amount of water intrusion near the bottom floor of an elevator hoistway, and a water level detector that detects water intrusion into the pit. a water amount detector, and an operation control means for setting the operating range of the elevator car to the second floor or higher based on the detection result of the water droplet detector, and raising the elevator car to the second floor or higher and stopping the elevator car based on the detection result of the water amount detector; It has been established. [Function] According to the operation control means of the present invention, a protective operation is started to protect the elevator car from flooding based on the detection results of each water detection device installed near the bit or in the pit. A protective operation is performed to reliably protect the elevator from flooding without any human intervention.

This is an elevator drive control device that controls the drive motor (7) using control signals based on the results.

Next, the operation of the apparatus of this embodiment having the above configuration will be explained with reference to the flowchart of FIG.

First, the water droplet amount detection means (3) determines whether or not water droplets are detected by the water droplet detector (1) (S-21).
, if not detected, the car operation determining means (5) determines the normal service (S-27). Also, if water droplets are detected, it is determined whether the amount of water droplets is greater than a specified value (
S-22) If the value is not greater than the specified value, normal service is determined in the same way as above. Next, if the amount of water droplets is above the specified value,
The water amount detection means (4) determines whether or not the detection signal of the water amount detector (2) has been input (S-23) At this time, the detection signal is not determined, that is, water has entered the bit (19). If not, the car operation determining means (5) decides to move the car to the second floor and perform normal elevator service between the second floor and the top floor (S-28).
, (S-29), also pit (l9) at (S-23)
If water intrusion is detected, the water amount detection means (4) determines whether or not the amount of water intrusion exceeds the specified value (S-24).
If it is not above the specified value, the car operation determining means (5) decides to move the car to the second floor and provide normal elevator service between the second floor and the top floor (S-28);
If it is determined in (S-29) and (S-24) that the amount of flooding exceeds the specified level, the car will be moved to the top floor to protect the elevator equipment from flooding, and the flooding situation will be resolved. The car operation determining means (5) makes a determination to stop the elevator until the elevator is stopped.

Furthermore, after the amount of water droplets exceeding the specified value is detected in (S-23), when the water droplet detector (1) no longer detects water droplets, the process returns to normal service (S-29). In the above embodiment, the water drop detector (1) and water amount detector (2) shown in Fig. 1 were used to detect water intrusion, but in the case of a home elevator, the landing may be located in the garage. The system predicts that the elevator will be flooded with water due to the continuous flow of water from the faucet, and automatically takes steps to protect the elevator from water.
