Description

[Technical Field]

[0001] The present disclosure relates to an elevator and an elevator flood management system. [Background technology]

[0002] A conventional elevator is described in Patent Document 1. This elevator is equipped with a flood sensor and a control panel installed in the pit of the elevator shaft. The flood sensor outputs a flood signal to the control panel indicating that the pit is flooded when a predetermined amount of water flows into the pit during heavy rain or during cleaning of the landing. Furthermore, when the control panel receives the flood signal from the flood sensor, it stops the car at the top floor to prevent the car from becoming flooded. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-161288 Summary of the Invention [Problem to be solved by the invention]

[0004] In the elevator described above, when the flood sensor detects flooding in the pit, the pit is already filled with water to a certain depth, which can require time and effort to drain the water, inspect, and replace equipment.

[0005] More specifically, as shown in FIG. 6, a large amount of rainwater 10 that has fallen in the elevator hall 5 may flow into the elevator shaft 8 through gaps in the hall doors 4, causing flooding, or when a cleaning worker 12 pours cleaning water 14 from a bucket 13 into the elevator hall 5 to clean it, some of the water may flow into the elevator shaft 8 through gaps in the hall doors 4, causing flooding.

[0006] In this case, if the elevator car 2 is waiting on a floor below the floor where the rainwater 10 and cleaning water 14 are entering, the rainwater 10 and other water will fall on the car from above. If there is a passenger 11 inside the car 2, they will notice the rainwater 10 and cleaning water 14 seeping into the car and contact the elevator management company, etc. However, in the case of flooding caused by heavy rain, if there is no one inside the car 2, even if the on-car equipment 6 is flooded, the flooding on the car will continue for a long period of time until a predetermined amount of rainwater 10 accumulates in the pit 3 and the pit flooding sensor 7 is activated. After a large amount of rainwater 10 flows into the pit 3 and the pit flooding sensor 7 is activated, the car 2 moves to the top floor 9 and remains in a dormant state to prevent flooding, as shown in Figure 7, but by this time the on-car equipment 6 is heavily flooded.

[0007] Therefore, in the above elevator, the pit flooding sensor 7 does not operate until a predetermined amount of rainwater 10 has accumulated in the pit 3, which may delay the detection of the elevator's flooding and affect the elevator's equipment, such as electronic components mounted on a circuit board. Furthermore, the rainwater 10 that seeps in from the landing 1 splashes into the elevator shaft 8, widening the flooded area and lengthening the time it takes for the amount of rainwater 10 to accumulate in the pit 3 that will activate the pit flooding sensor 7, which may require a great deal of effort for water drainage, inspection, equipment replacement, etc.

[0008] Therefore, an object of the present disclosure is to provide an elevator and an elevator flooding management system that can easily deal with water inflow from the landing into the hoistway early and reduce flooding damage to the hoistway. [Means for solving the problem]

[0009] In order to solve the above problems, the elevator disclosed herein comprises a threshold having a threshold groove and a threshold passage connecting the threshold groove with the underside, a landing door including an in-groove storage portion housed in the threshold groove and moving as guided by the threshold groove, a gutter that receives at least some of the water that flows downward in the threshold passage and drips downward from the threshold groove, a water storage portion that stores water that has flowed down the gutter, a landing flooding sensor that detects the presence or absence of flooding based on the water stored in the water storage portion, an alarm unit that can alarm the occurrence of flooding, and a control device that causes the alarm unit to alarm that flooding has occurred when it determines that flooding has occurred based on a signal from the landing flooding sensor.

[0010] According to the present disclosure, water that flows into a landing for some reason can be contained in a water storage unit via a threshold groove, threshold passage, or gutter, and the landing flooding sensor detects the presence or absence of flooding based on the water stored in the water storage unit. Therefore, the volume of the water storage unit can be made smaller for each level compared to the volume of the pit at a predetermined depth, allowing flooding to be detected for each level in a shorter time than when flooding is detected solely by a pit flooding sensor installed in the pit, and flooding can be detected in its early stages. As a result, the alarm unit can notify the occurrence of flooding at an earlier stage than when flooding is detected solely by a pit flooding sensor installed in the pit, allowing people to recognize the occurrence of flooding at an earlier stage for each level. This makes it easier to respond quickly to water inflow from the landing to the elevator shaft, minimizing flooding damage to the elevator shaft and reducing the effort and time required for water drainage, inspection, equipment replacement, etc.

[0011] Another aspect of the elevator according to the present disclosure includes a threshold having a threshold groove and a threshold passageway connecting the threshold groove with the underside, a landing door including an in-groove storage portion housed in the threshold groove and moving as guided by the threshold groove, a gutter that receives at least a portion of the water that flows downward in the threshold passageway and drips downward from the threshold groove, a water storage portion that stores the water that has flowed down the gutter, a landing flooding sensor that detects the presence or absence of flooding based on the water stored in the water storage portion, and an output portion that outputs a signal indicating the occurrence of flooding to one or more external information processing devices based on the signal indicating the occurrence of flooding output by the landing flooding sensor.

[0012] According to the present disclosure, water that flows into a landing for some reason can be contained in a water storage unit via a threshold groove, threshold passage, or gutter, and the landing flooding sensor detects the presence or absence of flooding based on the water stored in the water storage unit. Therefore, the volume of the water storage unit can be made smaller for each level compared to the volume of the pit at a given depth, allowing flooding to be detected for each level in a shorter time and at an early stage compared to when flooding is detected using only a pit flooding sensor installed in the pit. As a result, information on the occurrence of flooding for each level can be output to the outside at an earlier stage compared to when flooding is detected using only a pit flooding sensor installed in the pit. For example, this allows elevator managers to be notified of flooding for each level at an earlier stage. This makes it easier to respond to water inflow from the landing to the elevator shaft early, minimizing flooding damage to the elevator shaft and reducing the effort and time required for water drainage, inspection, equipment replacement, etc.

[0013] In addition, in the present disclosure, the gutter may be capable of receiving at least a portion of the water flowing downward along the wall surface on the elevator shaft side in the depth direction of the threshold.

[0014] This configuration allows most of the water that has overflowed the threshold groove to be contained within the gutter, thereby reducing the amount of water that splashes into the elevator shaft during flooding, such as during heavy rain, and making it easier to quickly detect the occurrence of flooding.

[0015] In addition, the present disclosure may include one or more water outflow passages that are connected to the water storage section and allow the water stored in the water storage section to flow out on the side wall side of the elevator shaft, and a water absorption member that is fixed to the side wall and is capable of absorbing water from the water outflow passages.

[0016] If flooding is detected solely by a pit flood sensor installed in the pit, the moment the pit flood sensor detects flooding, the water that has flooded the elevator shaft will easily splash over a wide area within the elevator shaft, causing widespread damage.

[0017] In contrast, with this configuration, water that has flowed into the landing can be efficiently guided to the water-absorbing member via the threshold groove, threshold passage, gutter, water storage section, and water outflow passage, preventing the water that has flowed into the landing from spreading over a wide area. This makes it easier to further reduce the labor and time required for water drainage treatment, inspection, equipment replacement, etc. Furthermore, when the amount of water that has flowed into the landing is small, the water absorbed by the water-absorbing member can be allowed to evaporate naturally in the water-absorbing member. This makes it possible to omit water drainage treatment, inspection, equipment replacement, etc., and to eliminate the need to take any measures to prevent water from flowing into the elevator shaft from the landing.

[0018] Furthermore, in the present disclosure, the thresholds, gutters, water storage sections, and platform flooding sensors may be provided in the same number as the number of platform areas so as to correspond to the respective platform areas, and may be equipped with an audio output device installed in the car, and when only one of the platform flooding sensors detects the occurrence of flooding, the car may land at the platform corresponding to the platform flooding sensor that detected the occurrence of flooding, and the audio output device may output a message indicating that flooding has occurred at the platform where the car has landed.

[0019] When a platform flooding sensor corresponding to each platform is installed around the platform in the elevator shaft, if only one platform flooding sensor detects flooding, there is a high possibility that flooding has occurred at the platform corresponding to that platform flooding sensor due to special circumstances, such as cleaning the platform with water.

[0020] According to this configuration, when only one landing flooding sensor detects flooding, the car lands at the landing corresponding to the landing flooding sensor that detected the flooding, and the audio output device outputs a message indicating that flooding is occurring at the landing where the car has landed. Therefore, by outputting this message, it is possible to notify people at the landing that flooding has occurred at that landing due to the special circumstances, and for example, to notify people who are cleaning the landing with water that flooding has occurred. Therefore, without providing a new audio output device at each landing, it is possible to notify people at that landing of the occurrence of flooding using the existing audio output device installed in the car, and it becomes possible to deal with the flooding at that floor early.

[0021] Furthermore, in the present disclosure, the thresholds, gutters, water storage units, and platform flooding sensors may be provided in the same number as the number of platform so as to correspond to each platform, and may comprise a voice output device installed in a car, and a platform operating panel that is installed at each platform and includes a car call button and a platform display unit, and when only one of the platform flooding sensors detects the occurrence of flooding, one or more of the platform display units, including the platform display unit installed at the platform corresponding to the platform flooding sensor that detected the occurrence of flooding, may display a message indicating that flooding has occurred at the platform corresponding to the platform flooding sensor that detected the occurrence of flooding.

[0022] According to this configuration, flooding at a specific landing can be reported early using a landing control panel including one or more car call buttons and a landing display unit, making it easier for people to identify the landing at the floor where flooding has occurred.

[0023] In addition, in the present disclosure, the thresholds, gutters, water storage sections, and platform flooding sensors may be provided in the same number as the number of platform areas so as to correspond to each platform, and when multiple platform flooding sensors detect the occurrence of flooding, the car may land at the platform on the top floor and enter a paused or standby state.

[0024] When thresholds, gutters, water storage sections, and platform flooding sensors are provided in the same number as the number of platform areas so as to correspond to each platform, if multiple platform flooding sensors detect flooding, there is a high possibility of flooding due to heavy rain.

[0025] According to this configuration, when multiple landing flooding sensors corresponding to multiple landings detect flooding, the car lands at the top floor landing and goes into a dormant or standby state, thereby preventing damage to equipment installed on the car from rainwater coming from the landings during heavy rain.

[0026] Furthermore, in the present disclosure, the one or more water outflow passages may have a first water outflow passage and a second water outflow passage located above the first water outflow passage, and the conditions for the landing flooding sensor to detect the flooding may include an inflow amount of water per unit time flowing into the water storage section being greater than the discharge amount of water per unit time discharged from the first water outflow passage.

[0027] According to this configuration, by adjusting the maximum amount of water discharged per unit time from the first water outflow passage, if the maximum amount of water discharged per unit time is greater than the amount of water flowing into the water storage section per unit time, the water discharged from the first water outflow passage can be absorbed into the water absorption member and then allowed to dry naturally without the landing flooding sensor detecting flooding. Therefore, if the amount of water flowing into the landing is small, the water can be automatically disposed of without any human effort.

[0028] On the other hand, if the amount of water flowing into the water storage section per unit time is greater than the maximum discharge amount, the landing flooding sensor can be made to detect flooding, and the water discharged from the first and second water outflow passages can be absorbed into the water absorption member, then allowed to flow down through the water absorption member and into the pit. Therefore, in this case, it is possible to notify people of the occurrence of flooding, control the flow of water, and prevent water from scattering over a wide area within the elevator shaft, thereby reducing the effort and time required for water drainage, inspection, equipment replacement, etc.

[0029] In addition, the elevator flooding management system according to the present disclosure comprises a plurality of elevators of the above-described different aspect and an information processing device at an information center that manages the operation of the plurality of elevators, wherein the information processing device is included in the one or more information processing devices of each of the elevators, and when the information processing device receives a signal indicating that flooding has occurred from the output unit of the elevator, it outputs a signal indicating that flooding has occurred in the elevator including the output unit to one or more mobile terminals that are linked to the elevator including the output unit that output the signal and that are portable by a person.

[0030] According to the present disclosure, when flooding occurs in any elevator, flood information for the elevator corresponding to one or more mobile devices linked to the flooded elevator can be transmitted via an information processing device. Therefore, it is possible to notify the owners of the one or more mobile devices that flooding has occurred in the elevator corresponding to the owner, and to notify, for example, the on-site manager and the elevator maintenance staff, that flooding has occurred in the elevator. This makes it easier to deal with the inflow of water from the landing into the hoistway early and minimize flood damage to the hoistway. [Effects of the Invention]

[0031] The elevator and elevator flooding management system according to the present disclosure make it easy to deal with water inflow from the landing into the hoistway early on, and to reduce flooding damage to the hoistway. [Brief explanation of the drawings]

[0033] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that, when multiple embodiments or variations are included below, it is anticipated from the beginning that new embodiments can be constructed by appropriately combining their characteristic features. In the following examples, the same components in the drawings are denoted by the same reference numerals, and redundant explanations will be omitted. The multiple drawings include schematic diagrams, and the dimensional ratios of the length, width, height, etc. of each component between different drawings do not necessarily match. In this specification, the requirement of "approximately..." is satisfied if a person appears roughly like... For example, the requirement of "approximately parallel" is satisfied if a person appears roughly parallel.

[0034] FIG. 1 is a diagram illustrating a method of transmitting information in an example of a flood management system 15 for an elevator 50. Note that the flood management system 15 includes multiple elevators 50, but FIG. 1 illustrates only one elevator 50. The multiple elevators 50 have the same configuration. In the following, the structure and operation of the elevator 50 will be described using the elevator 50 illustrated in FIG. 1.

[0035] As shown in FIG. 1, the flooding management system 15 includes multiple elevators 50 as well as an information processing device 24. Each elevator 50 includes a car 2, a hall display unit 20b installed at each floor landing, hall flooding sensors 21 installed in the elevator shaft around each landing to detect whether the landing is flooded, a pit flooding sensor 7 installed in the pit below the elevator shaft to detect whether the pit is flooded, a communication device 22a used to send information about the elevator 50 to the information processing device 24, and a control panel 16 as a control device for controlling each device in the elevator 50. Inside the car 2, there is an in-car interphone 18 which is an audio output device, and an announcement device 19 which generates and outputs automated voices. The announcement device 19 is included in the notification unit, and the communication device 22a is included in the output unit.

[0036] The information processing device 24 is installed in an information center of a maintenance company that manages multiple facilities 37 over a wide area. The multiple facilities may include, for example, one or more of a department store, a hotel, an office building, a university, and an art museum. The information processing device 24 receives information about the elevator 50 via the control panel 16, the elevator-side communication device 22a, the communication line 23a, and the information processing device-side communication device 22b. As will be described in detail later, upon receiving information about flooding from the elevator 50, the information processing device 24 transmits the information about the flooding to one or more mobile terminals 27 linked to the elevator 50 via the communication device 22b and the communication line 23b, thereby notifying the user of the mobile terminal 27 of the information. Each of the communication line 23a and the communication line 23b may include at least one of a dedicated line and the Internet.

[0037] Next, the structure and operation of each device will be explained in more detail. The hall display unit 20b is installed on the hall operating panel 20 provided at each floor hall. The hall operating panel 20 is provided with a car call button 20a. The hall display unit 20b is, for example, arranged at a position higher than the car call button 20a on the hall operating panel 20. The hall display unit 20b is composed of, for example, a liquid crystal panel or an organic EL panel. The hall display unit 20b is controlled by the control panel 16 to be able to display a message that identifies the floor where flooding has occurred, such as "Flooding occurring at the 8th floor hall," and is also able to display a message that simply indicates that flooding has occurred, such as "Flooding occurring." The hall display unit 20b is included in the notification unit.

[0038] The landing flooding sensor 21 and the pit flooding sensor 7 may each be configured with any known water level sensor that can detect when the water level has reached a predetermined level or above. The landing flooding sensor 21 and the pit flooding sensor 7 may each be configured with, for example, a float-type liquid level gauge equipped with an inspection mechanism that pushes a float upward, or may be configured with a liquid level gauge with an inspection mechanism that is provided in a container and includes a float that moves according to the position of the liquid level, and an arm that supports the float so that it can swing freely. The installation location of the landing flooding sensor 21 will be explained in detail later using Figure 4.

[0039] The communication device 22a may include a terminal to which an antenna or a cable is connected, and may further include a VPN (Virtual Private Network) router, and may output a signal to the information processing device 24 via the VPN router. The VPN router checks the destination of the packet, and if the packet is destined for the Internet, it sends it directly to the Internet via an Internet service provider, and if the packet is destined for a private address of the opposing site, it performs VPN processing such as tunneling and encryption.

[0040] For example, in IP security, which encrypts and authenticates IP (International Protection) packets, a VPN can be constructed using a communication mode called "tunnel mode." A VPN router integrates and connects multiple LANs connected via the Internet to form a single network. Therefore, by using a VPN router, multiple specified devices connected via the Internet can belong to the same network.

[0041] The communication device 22b may include a terminal to which an antenna or a cable is connected, and may further include a VPN router and a gateway. Here, the VPN router plays a role similar to that of the VPN router described above, and the gateway is provided to automatically convert data formats and enable data exchange between networks with different protocols. Also, if the mobile terminal 27 is a smartphone, the information processing device 24 outputs a signal to the mobile terminal 27 via, for example, a mobile phone adapter, an adapter router, and the Internet. Here, the mobile phone adapter is a device that allows the information processing device 24 to be connected to a mobile phone.

[0042] The in-car interphone 18 is provided to enable communication between people outside the car 2 and people inside the car 2 in emergencies, etc. The announcement device 19 has a voice generation unit (not shown) that generates a synthetic sound under the control of the control panel 16, and a speaker (sound output unit) electrically connected to the voice generation unit. The synthetic sound is synthesized by the voice generation unit based on a signal from the control panel 16, and an automated voice based on the synthesized sound is output from the speaker. The synthesized sound (automated voice) output by the announcement device 19 is a voice that can notify people that flooding has occurred, such as "The car is flooded." The announcement device may be installed outside the car, or may be configured to generate a synthetic sound (automated voice) under the control of the control panel and output the synthesized sound from the speaker of the in-car interphone 18 into the car. Alternatively, the speaker of the in-car interphone 18 may be used as the speaker of the announcement device 19, and the in-car interphone 18 and the announcement device 19 may share a speaker.

[0043] Next, the installation structure of the landing flooding sensor 21 and the operation of the elevator 50 when the landing is flooded will be described. Fig. 2 is a diagram illustrating the structure around the landing in the elevator 50, Fig. 3 is a schematic diagram illustrating the structure of the part viewed from arrow A in Fig. 2, and is a diagram illustrating the structure around the landing in the hoistway. Fig. 4 is a diagram of the area around the landing flooding sensor 21 in the hoistway 8 as seen from one side in the width direction of the hoistway 8, and is a schematic cross-sectional view illustrating the drainage operation within the hoistway in the elevator 50.

[0044] As shown in FIGS. 2 and 3 , the elevator 50 has a gutter 30 below the threshold 28 of each landing 1. The gutter 30 is fixed to the lower end of the threshold 28 by a fixing means, such as a fastening means, a weld, or an adhesive. The gutter 30 extends substantially parallel to the threshold 28 and in the width direction of the hoistway 8. As shown in FIG. 3 , the threshold 28 has a threshold groove 29 extending in the width direction. This threshold groove 29 is provided to guide a shoe (not shown) constituting a groove accommodation portion accommodated in the threshold groove 29 in the landing door 4 (see FIG. 4 ), thereby stably moving the landing door 4. The threshold 28 further has a plurality of threshold passages 33. The plurality of threshold passages 33 are provided at intervals in the width direction and extend vertically. The threshold passages 33 communicate between the threshold groove 29 and the lower surface 28a of the threshold 28.

[0045] When viewed vertically, the inner surface of the gutter 30 overlaps all of the threshold passages 33 and is positioned at a location overlapping the wall surface (end surface) 28b of the threshold 28 on the hoistway side in the depth direction. The end 30a of the gutter 30, which is located at the farthest depth in the opening, is located further back in the depth direction than the farthest depth position on the wall surface 28b. This allows the gutter 30 to catch most of the water, indicated by arrow a, that flows downward through the threshold groove 29 and the threshold passage 33 and drips from the threshold groove 29. It also catches most of the water, indicated by arrow b, that flows downward along the wall surface 28b on the hoistway side of the threshold 28 in the depth direction. To prevent the hall doors 4 from becoming unable to move smoothly, the elevator 50 may have one or more foreign object removal holes in the threshold 28 that allow foreign objects that have entered the threshold groove 29 to fall into the hoistway side. The foreign object removal holes connect the threshold groove and the underside of the threshold. The threshold passage 33 may coincide with such a foreign object removal hole, in which case there is no need to provide a new threshold passage 33.

[0046] As shown in FIG. 4, the elevator 50 further includes a rainwater manhole 31 and a water-absorbing member 35, which constitute a water storage section. Although not shown, the rainwater manhole 31 is fixed to the lower end of the threshold 28 or the wall of the elevator shaft 8 by, for example, a fastening means, a weld, or an adhesive. The rainwater manhole 31 has a water storage chamber 31a that stores water. The gutter 30 has an opening on one side in the extension direction that is sealed, and an opening on the other side in the extension direction that overlaps the upper opening of the water storage chamber 31a when viewed vertically. This allows water that has flowed down the gutter 30 to flow into the water storage chamber 31a. It is preferable that the vertical height of the lowest vertical position at the bottom of the gutter 30 gradually decreases from one end in the extension direction to the other end in the extension direction (the end on the rainwater manhole 31 side in the extension direction), so that the water stored in the gutter 30 can flow smoothly toward the rainwater manhole 31. As long as the water flowing through the gutter 30 can flow into the water storage chamber 31a, the opening on the other side of the gutter 30 does not necessarily have to overlap with the upper opening of the water storage chamber 31a when viewed vertically.

[0047] One or more water outflow passages 32 communicate with the water storage chamber 31a, and each water outflow passage 32 discharges water from the water storage chamber 31a toward one side wall 34 in the width direction of the elevator shaft 8. The one or more water outflow passages 32 include a first water outflow passage 32a and a second water outflow passage 32b located above the first water outflow passage 32a. The water absorbing member 35 is made of a material that has the property of absorbing and retaining water, such as an absorbent sponge.

[0048] The water-absorbing member 35 is fixed to one side wall 34 in the width direction of the elevator shaft 8 by a fixing means such as a fastening member or adhesive. The water-absorbing member 35 is installed continuously in the height direction, for example, from a height approximately equal to that of the uppermost water outflow passage 32 among one or more water outflow passages 32 communicating with the rainwater manhole 31 corresponding to the landing 1 on the highest floor, to the pit 3. The water-absorbing member 35 is preferably configured as a single unit, but may also include multiple parts spaced apart from one another. The water-absorbing member 35 includes water receiving portions installed at positions capable of receiving water discharged from each water outflow passage 32. Here, the number of water receiving portions corresponds to the number of water outflow passages 32 in the elevator 50.

[0049] The landing flooding sensor 21 detects the water level in the water storage chamber 31a. When the water level in the water storage chamber 31a reaches a predetermined level, the landing flooding sensor 21 outputs a signal indicating that the landing 1 is flooded to the control panel 16 via the signal line 21a. As shown in FIG. 4, the water storage chamber 31a may include a first water storage chamber 31b into which water flows from the gutter 30, a second water storage chamber 31c whose water level is detected by the landing flooding sensor 21, and a connecting passage 31d that connects the lower end of the first water storage chamber 31b with the lower end of the second water storage chamber 31c. This prevents water from the gutter 30 from directly impinging on the landing flooding sensor 21, stabilizing the behavior of the landing flooding sensor 21 and reducing the volume of the water storage chamber 31a. Therefore, the landing flooding sensor 21 can detect flooding of the landing early and accurately.

[0050] Next, an example of the operation of the flood management system 15 will be described. Figure 5 is a flowchart that explains an example of the procedure for dealing with flooding in the flood management system 15. Referring to Figure 5, when the elevator 50 is properly installed in the facility and put into operation, the flow starts, and the control panel 16 determines whether the landing flood sensor 21 on each floor is operating, and if at least one landing flood sensor 21 is operating, it checks the operating time (S101).

[0051] For example, elevator 50 is equipped with a timer (not shown). Control panel 16 confirms the operating time by exchanging information with the timer. Next, control panel 16 checks whether pit flooding sensor 7 in pit 3 is operating (S102), and further determines the operation of landing flooding sensor 21 and pit flooding sensor 7 to determine whether neither is operating, both are operating, or only landing flooding sensor 21 is operating (S103).

[0052] When neither the landing flooding sensor 21 nor the pit flooding sensor 7 is operating, the elevator 50 continues normal operation. Normally, when flooding occurs, the landing flooding sensor 21 operates, and then after some time the pit flooding sensor 7 operates, so when both the pit flooding sensor 7 and the landing flooding sensor 21 are operating, the flooding has progressed to the final stage. In this case, the control panel 16 moves the car 2 to the top floor 9 and stops it so that it cannot move (S201), and the flow ends.

[0053] Next, if only the landing flooding sensor 21 is operating, it means that rainwater 10 or the like is seeping in from the elevator hall 5 in front of the landing 1 corresponding to that landing flooding sensor 21, and it is determined whether the intrusion of rainwater 10 is due to heavy rain or cleaning water 14 by the cleaning worker 12 (S104). If the landing flooding sensors 21 on multiple floors are operating, it is considered that the flooding is due to heavy rain, so the car 2 is moved to the top floor 9 and a suspension procedure is performed, and a message indicating that flooding has occurred, such as "Flooded," is displayed on the landing display unit 20b on the floor where the landing flooding sensor 21 is operating.

[0054] Furthermore, data is transmitted from the arithmetic unit 17 of the control panel 16 to the information processing device 24 at the information center via the communication devices 22a and 22b, and flooding information is transmitted from the information processing device 24 to the mobile terminals 27 of the local manager 25 and the on-site staff 26 via the communication device 22b. The local manager 25 who received the information checks the hall display unit 20b of each floor, and installs water stops and sandbags at the hall 1 of the floor where "Flooded" is displayed on the hall display unit 20b, for example, to prevent flooding (S202), after which the flow ends.

[0055] The arithmetic device 17 is preferably configured by a computer, for example, a microcomputer, and includes a control unit and a storage unit. The control unit, i.e., the processor, includes, for example, a CPU (Central Processing Unit). The storage unit is configured by a hard disk drive (HDD), a semiconductor memory, etc., and the semiconductor memory is configured by a non-volatile memory such as a ROM (Read Only Memory) or a volatile memory such as a RAM (Random Access Memory). The storage unit may be configured by only one storage medium, or may be configured by multiple different storage media. The CPU reads and executes programs and the like stored in the storage unit in advance. The non-volatile memory stores control programs, predetermined thresholds, etc. in advance. The volatile memory temporarily stores the read programs and processing data.

[0056] Also, in this case, instead of displaying a message indicating that flooding has occurred only on the hall display unit 20b of the operating floor, information indicating that flooding has occurred on the operating floor along with information that can identify the operating floor of the hall flood sensor 21 may be displayed on the hall display units 20b of all floors, for example, "Flooding has occurred on the 3rd and 8th floors" may be displayed on the hall display units 20b of all floors. According to this modification, a person can identify the hall that is flooded just by checking the display on one hall display unit 20b.

[0057] On the other hand, when one landing flooding sensor 21 is operating only on a specific floor, it is determined whether the flooding on the specific floor is due to the cleaning worker 12, or whether the flooding on only the specific floor is due to the building environment, based on the operation time of the landing flooding sensor 21 (S105). When the landing flooding sensor 21 is operating for a period of time shorter than the predetermined period, it is considered that the cleaning worker 12 has poured cleaning water 14 in a bucket 13, for example, a 10-liter bucket 13 of cleaning water 14, into the elevator hall 5, and some of the cleaning water 14 has temporarily seeped into the elevator shaft 8.

[0058] In this case, it is necessary to notify the cleaning worker 12 working at the landing 1 that the car is flooded. In this case, the control panel 16 first moves the car 2 to the floor where the landing flood sensor 21 was activated, and causes the landing display unit 20b of that floor to display, for example, "Flooded," and also causes the announcement device 19 to output a voice message indicating flooding, such as "Flooded." In this way, the cleaning worker 12 is alerted. After this warning operation is completed, the control panel 16 moves the car 2 to the top floor 9 to prevent the on-car equipment 6 from being flooded, and causes the car 2 to wait there (S203), and the flow ends.

[0059] The operation of S203 is illustrated in Fig. 2. As shown in Fig. 2, when cleaning worker 12 sprinkles cleaning water 14 from bucket 13 into elevator hall 5 on a specific floor and some of the water seeps in through hall 1, hall flooding sensor 21 on the specific floor is activated, and flooding management system 15 causes car 2 to move to the operating floor of hall flooding sensor 21, give a voice warning to cleaning worker 12, display a message on hall display unit 20b, and then wait on top floor 9.

[0060] On the other hand, if the landing flooding sensor 21 has been operating for a longer period of time than the predetermined time, it is assumed that a particular floor is flooded due to heavy rain. For example, it is possible that rainwater 10 that has been traveling down the stairs has nowhere to go on the lowest floor and is seeping into the elevator shaft 8 of the elevator 50 from the elevator hall 5. In this case, the above-mentioned S202 is also performed, and the landing display unit 20b of the floor on which the landing flooding sensor 21 is operating displays, for example, "Flooded," and the flooding information is sent to the mobile terminals 27 of the on-site manager 25 and the on-site staff 26, so that water stops and sandbags are installed at the landing 1 of the floor on which, for example, "Flooded" is displayed on the landing display unit 20b, thereby preventing flooding. Then, the flow ends.

[0061] Next, an example of a method for detecting the infiltration of rainwater 10 and the like from the landing 1 will be described in more detail using Figure 4. Referring to Figure 4, rainwater 10 and the like flowing in from the elevator hall 5 in front of the landing 1 infiltrates into the hoistway 8 along the threshold 28 of the landing 1, passes through the wall surface 28b on the far side in the depth direction of the threshold 28 and the threshold groove 29, and flows into a gutter 30 with a certain slope installed below the threshold 28. The rainwater 10 that flows into the gutter 30 is collected in a rainwater manhole 31. This prevents the rainwater 10 and the like that infiltrates from the landing 1 from splashing into the hoistway 8.

[0062] The rainwater manhole 31 has one inlet for rainwater 10. In this embodiment, the maximum amount of water discharged per unit time from the first water outflow passage 32a communicating with the rainwater manhole 31 is smaller than the maximum amount of water discharged per unit time from the second water outflow passage 32b communicating with the rainwater manhole 31. The landing flooding sensor 21 is a float switch that is activated when water accumulates in the rainwater manhole 31 up to a predetermined water level.

[0063] (amount of water flowing into the rainwater catch basin 31 per unit time)<(amount of water discharged from the first water outflow passage 32a per unit time) (1) When this condition is met, the inflowing rainwater 10 is discharged from the first water outflow passage 32a into the hoistway 8 without activating the landing flooding sensor 21. The drained rainwater 10 is then absorbed by the water absorbing member 35 attached to the side wall 34 of the hoistway 8 and allowed to dry naturally.

[0064] On the other hand, when a large amount of rainwater flows into the rainwater manhole 31 or when the cleaning water 14 flows in within a short period of time, the following formula (2) is established, the water level in the rainwater manhole 31 rises without being able to keep up with the drainage, and the landing flooding sensor 21 is activated.

[0065] (Amount of water flowing into the rainwater catch basin 31 per unit time)>(Amount of water discharged from the first water outflow passage 32a per unit time) (2)

[0066] Furthermore, when the water level in the rainwater manhole 31 rises above the position where the landing flooding sensor 21 operates, the water is discharged from the second water outflow passage 32b. The drained water is absorbed by a water absorption member 35 attached to the side wall 34 of the elevator shaft 8 and flows down through the water absorption member 35 to the pit 3. Therefore, water does not scatter over a wide area of ​​the elevator shaft 8, and water that seeps in from the landing 1 does not accumulate on the car or around the threshold 28 of the landing 1. Therefore, most of the water flows down to the pit 3 and accumulates there, shortening the time until the pit flooding sensor 7 operates. The maximum discharge amount of the first water outflow passage 32a can be adjusted by the cross-sectional area of ​​the first water outflow passage 32a and the difference in elevation between the first water outflow passage 32a and the second water outflow passage 32b, and can be adjusted appropriately for each specification.

[0067] According to this embodiment, rainwater 10 and the like that seeps in from the landing 1 is prevented from scattering over a wide area onto the car or inside the hoistway 8 by the water-absorbing member 35 fixed to the side wall 34 of the hoistway 8, so that flooding damage can be kept to a minimum. Also, because the fact that the landing flooding sensor 21 has been activated is displayed on the landing display unit 20b, it is easy for the local manager 25, who has been notified of the flooding information via his mobile terminal 27, to understand on which floor flood prevention measures should be taken. Also, if a cleaning worker 12 is present on the floor where the landing flooding sensor 21 has been activated, the cleaning worker 12 can be notified of the flooding, so that the cleaning worker 12 can easily notice the flooding and can stop work or change the direction in which the cleaning water 14 is flowing, thereby preventing water from seeping into the hoistway 8. In other words, according to this embodiment, not only can flooding from hall 1 be detected and dealt with early, but the number of areas in elevator 50 that become flooded can be reduced, and the car itself can also perform evacuation operations, thereby minimizing damage caused by flooding.

[0068] An example of the configuration of the flood management system 15 and elevator 50 according to an embodiment of the present disclosure, and their respective actions and effects, have been described above, but the technology of the present disclosure is not limited to these configurations and their respective actions and effects. Below, essential configurations and their respective actions and effects of the technology of the present disclosure will be described, followed by a description of configurations that are preferable to employ in the technology of the present disclosure, and their respective actions and effects.

[0069] [Configurations essential to the technology disclosed herein and their effects] The elevator 50 is equipped with a threshold 28 having a threshold groove 29 and a threshold passage 33 connecting the threshold groove 29 with the underside, a landing door 4 including an in-groove storage portion housed in the threshold groove 29 and moving as guided by the threshold groove 29, a gutter 30 that receives at least some of the water that flows downward in the threshold passage 33 and drips downward from the threshold groove 29, a water storage portion (rainwater manhole 31) that stores the water that has flowed down the gutter 30, a landing flooding sensor 21 that detects the presence or absence of flooding based on the water stored in the rainwater manhole 31, an alarm unit (announcement device 19 and landing display unit 20b) that can alarm the occurrence of flooding, and a control device (control panel 16) that causes the alarm unit to notify the occurrence of flooding when it determines that flooding has occurred based on a signal from the landing flooding sensor 21.

[0070] According to the present disclosure, water that flows into the landing for some reason can be collected in the rainwater manhole 31 via the threshold groove 29, threshold passage 33, and gutter 30, and the landing flooding sensor 21 detects the presence or absence of flooding based on the water collected in the rainwater manhole 31. Therefore, the volume of the rainwater manhole 31 can be made smaller for each level compared to the volume of the pit 3 at a predetermined depth. This allows flooding to be detected in a shorter time for each level than when flooding is detected using only a pit flooding sensor installed in the pit using conventional methods, and flooding can be detected in its early stages. As a result, the alarm unit can notify the occurrence of flooding at an earlier stage than when flooding is detected using only a flooding sensor installed in the pit, allowing people to be notified of flooding at an earlier stage for each level. This makes it easier to respond early to water inflow from the landing 1 to the elevator shaft 8, minimizing flood damage to the elevator shaft 8 and significantly reducing the labor and time required for water drainage, inspection, equipment replacement, etc.

[0071] In this disclosure, when the control panel 16 determines that flooding has occurred based on a signal from the landing flood sensor 21, it causes the notification unit to notify the occurrence of flooding. However, it is not necessary to notify the occurrence of flooding, and instead of notifying the occurrence of flooding, flood information may be output to one or more information processing devices outside the elevator. That is, the elevator may include both a notification unit and an output unit as in the above-described embodiment, but it may also have only one of the notification unit and the output unit.

[0072] That is, the elevator 50 comprises a threshold 28 having a threshold groove 29 and a threshold passage 33 connecting the threshold groove 29 with the underside, a landing door 4 including an in-groove storage portion housed in the threshold groove 29 and moving as guided by the threshold groove 29, a gutter 30 that receives at least some of the water that flows downward in the threshold passage 33 and drips downward from the threshold groove 29, a water storage portion (rainwater manhole 31) that stores the water that has flowed down the gutter 30, a landing flooding sensor 21 that detects whether or not flooding has occurred based on the water stored in the rainwater manhole 31, and an output unit (communication device 22a) that outputs a signal indicating that flooding has occurred to one or more external information processing devices 24 based on the signal indicating the occurrence of flooding output by the landing flooding sensor 21.

[0073] According to the present disclosure, water that flows into the landing for some reason can be collected in the rainwater manhole 31 via the threshold groove 29, threshold passage 33, and gutter 30, and the landing flooding sensor 21 detects the presence or absence of flooding based on the water collected in the rainwater manhole 31. Therefore, the volume of the rainwater manhole 31 can be made smaller for each level compared to the volume of the pit 3 at a predetermined depth. This allows flooding to be detected for each level in a shorter time than when flooding is detected using only a pit flooding sensor installed in the pit using conventional methods, and flooding can be detected in its early stages. As a result, compared to when flooding is detected using a flooding sensor installed in the pit, information on the occurrence of flooding can be output to the outside at an earlier stage for each level. For example, this allows elevator managers 25, 26 to be notified of the occurrence of flooding at an earlier stage for each level. This makes it easier to respond to water inflow from the landing 1 to the hoistway 8 early, minimizing flood damage to the hoistway 8 and significantly reducing the labor and time required for water drainage, inspection, equipment replacement, and other procedures.

[0074] [Configurations that are preferably adopted in the technology of the present disclosure, and their effects] The gutter 30 may be capable of receiving at least a portion of the water flowing downward along the wall surface of the threshold 28 on the hoistway 8 side in the depth direction.

[0075] According to this configuration, most of the water that has flowed over the threshold groove 29 can be contained within the gutter 30. Therefore, water that splashes into the elevator shaft 8 during flooding with a large amount of water, such as during heavy rain, can be suppressed, and the occurrence of flooding can be easily detected in a short time.

[0076] In addition, the present disclosure may also include one or more water outflow passages (first and second water outflow passages 32a, 32b) that are connected to the rainwater manhole 31 and allow the water contained in the rainwater manhole 31 to flow out on the side wall 34 side of the elevator shaft 8, and a water absorption member 35 that is fixed to the side wall 34 and can absorb water from the water outflow passages 32.

[0077] When flooding is detected using only a pit flood sensor installed in the pit using the conventional method, once the pit flood sensor detects flooding, the water that has flooded the hoistway is likely to splash over a wide area within the hoistway, causing widespread damage.

[0078] In contrast, with this configuration, water that has flowed into the landing 1 can be efficiently guided to the water absorbing member 35 via the threshold groove 29, threshold passage 33, gutter 30, rainwater manhole 31, and water outflow passage 32, and the water that has flowed into the landing 1 can be prevented from spreading over a wide area. This makes it easier to further reduce the labor and time required for water drainage treatment, inspection, equipment replacement, etc. Furthermore, when the amount of water that has flowed into the landing 1 is small, the water absorbed by the water absorbing member 35 can be allowed to evaporate naturally in the water absorbing member 35. This makes it possible to omit water drainage treatment, inspection, equipment replacement, etc., and to eliminate the need to take any measures to deal with water flowing from the landing 1 into the hoistway 8.

[0079] Furthermore, in the present disclosure, the thresholds 28, gutters 30, rainwater manholes 31, and platform flooding sensors 21 may be provided in the same number as the number of platform 1 so as to correspond to each platform 1, and an audio output device (announcement device 19) may be installed in the car 2, and when only one platform flooding sensor 21 detects the occurrence of flooding, the car 2 may land at the platform 1 corresponding to the platform flooding sensor 21 that detected the occurrence of flooding, and the announcement device 19 may output a message indicating that flooding has occurred at the platform 1 at which the car 2 has landed.

[0080] When a landing flood sensor 21 corresponding to each landing 1 is installed around the landing in the elevator shaft, if only one landing flood sensor 21 detects flooding, there is a high possibility that flooding has occurred at the landing 1 corresponding to that landing flood sensor 21 due to special circumstances, such as cleaning using water at that landing 1.

[0081] According to this configuration, when only one landing flooding sensor 21 detects the occurrence of flooding, the car 2 lands at the landing 1 corresponding to the landing flooding sensor 21 that detected the occurrence of flooding, and the announcement device 19 outputs a message indicating that flooding has occurred at the landing 1 where the car 2 has landed. Therefore, by outputting this message, it is possible to inform people at that landing 1 that flooding has occurred at that landing 1 due to the special circumstances in question, and for example, it is possible to inform people who are cleaning that landing 1 with water that flooding has occurred. Therefore, it is possible to inform people at that landing 1 of the occurrence of flooding using an existing voice output device (announcement device 19 in the above embodiment) that is normally installed in the car 2, without providing a new voice output device at each landing, and it becomes possible to deal with the flooding at that floor early.

[0082] Furthermore, in the present disclosure, thresholds 28, gutters 30, rainwater manholes 31, and platform flooding sensors 21 are provided in the same number as the number of platform 1 so as to correspond to each platform 1, and the system is equipped with an announcement device 19 installed in the car 2, and a platform operating panel 20 provided at each platform 1 and including a car call button 20a and a platform display unit 20b, and when only one platform flooding sensor 21 detects the occurrence of flooding, one or more platform display units 20b including the platform display unit 20b provided at the platform 1 corresponding to the platform flooding sensor 21 that detected the occurrence of flooding may display a message meaning that flooding has occurred at the platform 1 corresponding to the platform flooding sensor 21 that detected the occurrence of flooding.

[0083] According to this configuration, flooding at a specific hall 1 can be reported early using the hall operating panel 20, which includes one or more car call buttons 20a and a hall display unit 20b, making it easier for people to identify the hall 1 at the floor where flooding has occurred.

[0084] In addition, in the present disclosure, the thresholds 28, gutters 30, rainwater manholes 31, and platform flooding sensors 21 may be provided in the same number as the number of platform 1 so as to correspond to each platform 1, and when the multiple platform flooding sensors 21 detect the occurrence of flooding, the car 2 may land at the platform 1 on the top floor and enter a paused or standby state.

[0085] When the thresholds, gutters 30, rainwater manholes 31, and landing flooding sensors 21 are provided in the same number as the number of landings 1 so as to correspond to each landing 1, if multiple landing flooding sensors 21 detect flooding, there is a high possibility of flooding due to heavy rain.

[0086] According to this configuration, when multiple landing flooding sensors 21 corresponding to multiple landings 1 detect flooding, the car 2 lands on the top floor landing 1 and goes into a dormant or standby state. Therefore, it is possible to prevent the on-car equipment 6 installed on the car 2 from being damaged by rainwater from the landings 1 during heavy rain.

[0087] Furthermore, in the present disclosure, one or more water outflow passages 32 may have a first water outflow passage 32a and a second water outflow passage 32b located above the first water outflow passage 32a, and the conditions for the landing flooding sensor 21 to detect flooding may include the inflow amount of water per unit time flowing into the rainwater manhole 31 being greater than the discharge amount of water per unit time discharged from the first water outflow passage 32a.

[0088] According to this configuration, by adjusting the maximum discharge amount of water discharged from first water outflow passage 32a per unit time, if the maximum discharge amount is greater than the inflow amount of water per unit time into rainwater manhole 31, the water discharged from first water outflow passage 32a can be absorbed into water absorption member 35 and then allowed to dry naturally, without landing flooding sensor 21 detecting flooding. Therefore, when the amount of water that has flowed into landing 1 is small, the water can be automatically treated without any human effort.

[0089] On the other hand, if the amount of water flowing into the rainwater manhole 31 per unit time is greater than the maximum discharge amount, the landing flooding sensor 21 can be made to detect flooding, and the water discharged from the first and second water outflow passages 32a, 22b can be absorbed into the water absorption member 35, and then allowed to flow down through the water absorption member 35 before flowing into the pit 3. Therefore, in this case, the flow of water can be controlled and water can be prevented from scattering over a wide area within the elevator shaft 8, and as a result, the effort and time required for water drainage treatment, inspection, equipment replacement, etc. can be reduced.

[0090] In addition, the elevator flooding management system 15 comprises a plurality of elevators 50 each having the above-mentioned output unit, and an information processing device 24 at an information center that manages the operation of the plurality of elevators 50, and the information processing device 24 is included in one or more information processing devices that each elevator 50 outputs flooding information, and when the information processing device 24 receives a signal indicating that flooding has occurred from the above-mentioned output unit of the elevator 50, it outputs a signal indicating that flooding has occurred in the elevator 50 including the output unit to one or more mobile terminals 27 that are linked to the elevator 50 including the output unit that output the signal and that are portable by a person.

[0091] According to the present disclosure, when flooding occurs in any of the elevators 50, flooding information for the elevator 50 corresponding to one or more mobile devices 27 linked to the elevator 50 in which the flooding has occurred can be transmitted via the information processing device 24. Therefore, it is possible to notify the owners of the one or more mobile devices 27, etc., that flooding has occurred in the elevator 50 corresponding to the owners, etc., and it is possible to notify, for example, the on-site manager 25 and the on-site maintenance staff 26 of the elevator 50, etc., that flooding has occurred in the elevator 50. Therefore, it is easy to deal with the inflow of water from the hall 1 into the hoistway 8 early on, and it is easy to minimize flooding damage to the hoistway 8.

[0092] It should be noted that the present disclosure is not limited to the embodiments and their modifications described below, and various improvements and modifications are possible within the scope of the claims of the present application and their equivalents. Furthermore, among the components described so far, those components that are not described in the independent claims showing the highest concept are optional components and are not essential components.

[0093] For example, the pit flooding sensor 7 may not be present. Also, as long as the landing flooding sensor can operate, there is no need to provide a water passageway or water supply member for discharging water from the water storage unit. Also, the landing flooding sensor does not have to be installed in the elevator shaft sections corresponding to all floors, but may be installed, for example, only in the elevator shaft sections located around one or more landings where flooding is likely to occur based on experience with each elevator (these one or more landings being less than the number of landings the elevator has).

[0094] Furthermore, when viewed vertically, the wall surface on the hoistway side in the depth direction of the threshold does not have to overlap the inner surface of the gutter, and the gutter does not have to be able to efficiently contain water that flows down the wall surface. In the above embodiment, flood information is transmitted to the mobile terminal 27 of the on-site manager 25 and the mobile terminal 27 of the on-site person in charge 26 via the information processing device 24 at the information center. However, flood information may be transmitted to the mobile terminal of the on-site manager or the mobile terminal of the on-site person in charge without going through the information processing device at the information center. For example, flood information may be transmitted directly from the output unit of the elevator to the information processing device at the information center, the mobile terminal (information processing device) of the on-site manager, and the mobile terminal (information processing device) of the on-site manager. As described above, it is preferable for the elevator to have both an alarm unit and an output unit, but it is sufficient for the elevator to have at least one of the alarm unit and the output unit.
