As a feature of the management device 50 of an embodiment, first, a technology of detecting an abnormality occurring in the toilet bowl device 30, the toilet room 21, or the like and notifying information on the detected abnormality will be described. The abnormality detector 62 detects an abnormality of the toilet bowl device 30 or a facility or equipment installed inside or around the toilet room 21 when the use situation information acquired by the use situation information acquirer 61 matches predetermined conditions stored in the abnormality detection condition holder 75.
The notifier 63 determines a notification destination according to the contents of the abnormality detected by the abnormality detector 62 by referring to the notification condition holder 76, and notifies the determined notification destination of the information on the detected abnormality. The notifier 63 notifies the information necessary for the notification destination to examine necessary measures, in addition to an error code indicating the type of occurring abnormalities. For example, the notifier 63 may notify the information indicating the state of the toilet bowl device 30 or the toilet room 21, the captured image of the toilet bowl device 30 or the toilet room 21, and the like. The notifier 63 may directly notify the information on the detected abnormality to the terminal of the subject to be notified, may send the information on the detected abnormality to a representative telephone or a direct telephone of a company, an office, or the like, may transmit an email to a mail address, or may notify the information on the detected abnormality to a mobile phone or a mail address of a person in charge. The notifier 63 records information, such as the notification date and time, the notification destination, and the notification contents, in the notification history holder 74. When receiving the response from the notification destination, the notifier 63 displays the received response on the display device 52. The notifier 63 records the information, such as the presence/absence of response, the response date and time, and the response contents, in the notification history holder 74.
Details of the abnormality to be detected and a specific example of the notification destination will be described below.
The abnormality detector 62 may determine that the abnormality occurs when the use situation information indicating the use situation of the toilet bowl device 30 matches the conditions held in the abnormality detection condition holder 75. For example, the abnormality detector 62 may determine that the abnormality occurs when acquiring the information indicating that the amount of water inside the bowl of the toilet bowl device 30 exceeds a predetermined value. If sewage overflows from the bowl due to clogging of a drainage pipe, the sewage may have a great influence not only on the inside of the toilet room 21 but also on the surroundings thereof, so it is very important to organize a system that promptly detects the overflow of the sewage and notifies an appropriate subject that can take necessary measures for operating facilities and the like.
The amount of water in the bowl of the toilet bowl device 30 may be detected by the water level sensor installed on an inner surface or an outer surface of the bowl of the toilet bowl device 30. When the water level sensor is installed on the outer surface of the bowl, a contactless water level sensor such as a capacitance type may be installed. In addition, the contactless water level sensor such as the capacitance type may be installed on an outer surface of a trap provided between a drainage port at a lower portion of the bowl and the drainage pipe. After the toilet bowl device 30 is used and then the bowl is washed with washing water and the sewage is drained, pooled water remains in the bowl at a portion below an upper end of the trap, but even after a predetermined time elapses from drainage, when the water level sensor installed on the outer surface of the trap detects that water remains at the upper end of the trap, it is estimated that the sewage in the bowl is not drained from the drainage pipe due to the clogging of the drainage pipe, and as a result, it may be determined that an abnormality occurs.
When the sewage actually overflows from the bowl, since it is necessary to clean the toilet room 21 and perform a measure or the like that temporarily limit an access of a user to the toilet room 21 and the surroundings thereof, the notifier 63 notifies a subject in charge of cleaning the toilet room 21 in which the toilet bowl device 30 in which the abnormality occurs is installed and a subject managing the toilet room 21 of the occurrence of the abnormality. In addition, when it is estimated from other information or the like that the cause of the occurrence of the abnormality is due to a malfunction of the equipment such as the toilet bowl device 30, a subject that manufactures the toilet bowl device 30 in which the abnormality occurs may also be notified of the occurrence of the abnormality, may be requested to provide information on equipment or facilities in which the malfunction occurs, or may take orders for parts. In addition, when it is estimated from other information or the like that the cause of the occurrence of the abnormality is due to a malfunction of equipment or facilities such as a drainage pipe or a pump, a subject in charge of maintenance of equipment or facilities of the drainage pipe or the pump may also be notified of the occurrence of the abnormality and may be requested to repair or replace the equipment or facilities.
When the abnormality that sewage overflows from the bowl is detected in the toilet bowl device 30 installed in the toilet room 21 installed on an upper floor of a building having a plurality of floors, the notifier 63 may notify a subject managing floors below a floor on which toilet room 21 is installed or a subject managing stores around a floor on which the toilet room 21 is installed of the information on the abnormality, in addition to a subject managing the floor on which the toilet room 21 is installed. When sewage actually overflows, since there is a risk that the sewage spreads to the floor of the toilet room 21 and is infiltrated into a ceiling below the floor, or water is leaked from a ceiling of a downstairs, a subject managing the downstairs or the surroundings thereof may be notified of the abnormality, so it is possible to takes promptly necessary measures and to suppress the influence to the minimum.
The notifier 63 may notify the abnormality notification means 27 installed inside or around the toilet room 21 of the occurrence of the abnormality. As a result, a user who is about to enter the toilet room 21 to use the toilet room 21 or a user of the facility 20 around the toilet room 21 can be notified that the abnormality has occurred in the toilet room 21, can be prevented from entering the toilet room 21, or can be urged to move away from an area around the toilet room 21. In addition, it is possible to make a person in charge of stores or the like around the toilet room 21 take appropriate measures such as ventilation and notification. In addition, it is possible to promptly notify a person in charge who goes around the toilet room 21 that the abnormality occurs in the toilet room 21.
According to such a technology, it is possible to significantly shorten the time required to take appropriate measures after the occurrence of the abnormality, so the influence of the abnormality can be minimized. In addition, since the toilet room 21 can be appropriately maintained and managed, the convenience of the user of the facility 20 can be improved, and the comfort and operation conditions of the facility 20 can be improved.
The abnormality detector 62 may determine that the abnormality occurs when the use situation information indicating the operation conditions of the controller 31 for the user of the toilet bowl device 30 to input the operation instruction to the toilet bowl device 30 matches the conditions held in the abnormality detection condition holder 75. For example, the abnormality detector 62 may determine that the abnormality occurs when acquiring the information indicating that the same button of the controller 31 is continuously operated plural times. When a button for performing a function that is not assumed to be continuously performed plural times is continuously operated plural times, since there is a problem in the button or the configuration for performing the function thereof and it is estimated that the user's desired function is not performed, it may be determined that the abnormality occurs in the controller 31 or the toilet bowl device 30 operated by the controller 31. The abnormality detection condition holder 75 may hold, as the conditions, a type of operable buttons, the number of times of operation of the button determined as abnormal, an operation interval of the button in which it is determined that the button is continuously operated in association with each other. In the buttons that are assumed to be continuously operated plural times such as a button for changing a volume of a sound masking device for the toilet, the number of times of operation of the button determined as abnormal may more increase than that of other buttons.
In the state in which the seating sensor of the toilet bowl device 30 does not detect the seating, when the information indicating that a button for performing a private part cleaning function is pressed is acquired, it is estimated that the seating sensor or the button is broken, so it may be determined that the abnormality occurs.
When the information indicating that the button for stopping the private part cleaning function is not pressed for a predetermined time after the private part cleaning function of the toilet bowl device 30 is performed is acquired, it is estimated that the private part cleaning function or the button is broken, so it may be determined that the abnormality occurs.
When the communication is regularly performed between the controller 31 and the toilet bowl device 30, if the information indicating that the controller 31 and the toilet bowl device 30 cannot communicate for a predetermined time or longer is acquired, it is estimated that the communication function of controller 31 or the toilet bowl device 30 is broken, the controller 31 has fallen or has been taken out and thus is out of a communicable coverage with the toilet bowl device 30, or a state of charge of a battery of the controller 31 is insufficient, so it may be determined that the abnormality has occurred.
The notifier 63 notifies the subject managing the toilet room 21 in which the controller 31 or the toilet bowl device 30 in which the abnormality occurs is installed and the subject in charge of maintenance of the controller 31 or the toilet bowl device 30 of the occurrence of the abnormality. In addition, when it is estimated from other information that the controller 31 or the toilet bowl device 30 in which the abnormality occurs needs to be repaired or replaced, the subject that manufactures the controller 31 or the toilet bowl device 30 may also be notified of the occurrence of the abnormality and take orders for necessary parts.
In this way, it is possible to promptly detect and notify the abnormality that is difficult for a person in charge of management to find even after going around the toilet room 21 based on the operation conditions of the controller 31 and take necessary measures, so the convenience of the user of the toilet room 21 can be improved, and the comfort and the operation conditions of the facility 20 can be improved.
When a function to change a temperature of the toilet seat or a temperature of hot water for private part cleaning stops by an administrator, and when the information indicating that a button for changing the temperature is operated a predetermined number of times or more is acquired, the subject managing the toilet room 21 can be notified that it is estimated that many users desire to change the temperature.
In this way, it is possible to estimate the request of the user of the toilet bowl device 30 from the operation conditions of the controller 31 and notify the management subject of the estimated request, so the environment of the toilet room 21 can be improved and the convenience of the user can be improved.
When the use situation information indicating the state of facilities or equipment installed inside or around the toilet room 21 matches the conditions held in the abnormality detection condition holder 75, the abnormality detector 62 may determine that the abnormality has occurred. For example, the abnormality detector 62 may determine that the abnormality has occurred when acquiring the information indicating that the time it takes for the door 23 of the toilet room 21 or the door 25 of the private room 24 to be closed and then reopened is less than a predetermined value. The abnormality detector 62 calculates statistical values such as an average staying time from a staying time history of the private room 24 or the toilet room 21 for each private room 24, each toilet room 21, or each facility 20 to calculate a predetermined value for determining that the abnormality has occurred.
When the user stays in the toilet room 21 or the private room 24 for the predetermined time, since there is a risk that the user may be in a poor physical condition, the notifier 63 notifies a subject managing the toilet room 21 in which the abnormality has occurred of the occurrence of the abnormality and notifies the subject to rush to the toilet room 21. In addition, when it is estimated from another information or the like that the malfunction of the door 23 or the door 25 or the malfunction of the opening/closing sensor of the door 23 or the door 25 occurs, the subject in charge of the maintenance of the toilet room 21 with the malfunction is notified of the occurrence of the abnormality. In addition, when it is estimated from other information or the like that the door 23, the door 25, or the opening/closing sensor in which the abnormality occurs needs to be repaired or replaced, the subject that manufactures the door 23, the door 25, or the opening/closing sensor may also be notified of the occurrence of the abnormality and takes orders for necessary parts.
As a result, since it is possible to promptly detect the case where the abnormality occurs and take appropriate measures even when the abnormality occurs in the user of the toilet room 21, the user can safely use the toilet room 21 and the facility 20 and the comfort and operating conditions of the facility 20 can be improved. Further, the abnormality of the facility or equipment installed inside or around the toilet room 21 as well as the toilet bowl device 30 can be detected promptly, so that the toilet room 21 can be appropriately maintained and managed.
The abnormality detector 62 may determine that the abnormality has occurred in the toilet bowl device 30 or the facility or equipment installed inside or around the toilet room 21 when a combination of any two or more of the pieces of information held in the use situation information holder 73 matches the predetermined conditions. The notifier 63 notifies the subject in charge of managing the toilet room 21 of the occurrence of the abnormality, and when it is estimated that the facility or equipment needs to be repaired, replaced, or the like, the notifier 63 requests the subject in charge of maintenance of the facility or equipment to repair or replace the facility or equipment with the abnormality, and may order the necessary parts to the subject that manufactures the facility or equipment.
When the information indicating that the door 23 of the toilet room 21 or the door 25 of the private room 24 is closed for the predetermined time or longer, and the toilet bowl device 30 installed in the toilet room 21 or the private room 24 is not used for the predetermined time or longer is acquired or when the information indicating that the door 23 of the toilet room 21 or the door 25 of the private room 24 is not opened even when the toilet bowl device 30 is used and then the predetermined time or more elapses is acquired, there is a risk that the abnormality has occurred in the user, so it may be determined that the abnormality has occurred.
When the door 23 of the toilet room 21 or the door 25 of the private room 24 is closed and then the toilet bowl device 30 is not used, and the door 23 or the door 25 is opened before the predetermined time elapses, it is estimated that the toilet bowl device 30 malfunctions or the toilet bowl device 30, the private room 24, or the toilet room 21 is dirty and the toilet bowl device 30 cannot be used, so it may be determined that the abnormality has occurred.
When the door 25 of the private room 24 is open and the information indicating that the toilet bowl device 30 is used is acquired, it is estimated that the opening/closing sensor of the door 25 or the toilet bowl device 30 malfunctions, so it may be determined that the abnormality has occurred.
When the toilet bowl device 30 is not used for a predetermined time or longer, it may be determined that the abnormality has occurred in the toilet bowl device 30 or in the toilet room 21 in which the toilet bowl device 30 is installed. The predetermined time may be calculated from the past usage frequency of the toilet bowl device 30 or the toilet room 21.
In the toilet bowl device 30 equipped with a hot water tank for private part cleaning, if the temperature of the hot water in the hot water tank does not change more than the predetermined value even though the private part cleaning function is executed, it is estimated that a valve for the hot water tank, a private part cleaning nozzle, or the like is broken, so it may be determined that the abnormality has occurred.
The abnormality detection conditions as in the above example may be automatically acquired by machine learning. For example, the contents of the abnormality when the abnormality actually occurs and the use situation information at that time are collected from the plurality of facilities 20, the toilet room 21, and the toilet bowl device 30, and the relationship between the use situation information and the contents of the abnormality may be learned by performing supervised learning using these actual data as teacher data. This machine learning may be executed by a server device or may be executed by a plurality of computers using a technology such as cloud computing. The learned condition may be delivered to the management device 50 at any time and stored in the abnormality detection condition holder 75. The management device 50 may include a learner that executes the machine learning. In this case, the learner acquires, from the notification destination notifying the abnormality detected by the abnormality detector 62, information on whether or not the abnormality actually has occurred or the information such as the contents of the abnormality, the state of the toilet room 21, the toilet bowl device 30, or the like, the taken measures, and the results of the measures when the abnormality has occurred, and may further learn abnormality detection conditions by executing the supervised learning using these pieces of information and the use situation information when it is determined that the abnormality has occurred as the teacher data to update the abnormality detection condition holder 75.
In this way, according to the technology of some embodiments, even if an abnormality occurs in the toilet room 21 or the toilet bowl device 30, it is possible to promptly detect the abnormality, notify the appropriate notification destination of the detected abnormality, and take necessary measures, so the influence of abnormality can be suppressed to the minimum. Further, since the occurrence of the abnormality is detected based on the information that can be collected from the toilet room 21 or the toilet bowl device 30, it is possible to suppress the cost of newly installing a sensor or the like for detecting the abnormality.
Next, as a feature of the management device 50 of some embodiments, a technology of comprehensively managing the plurality of toilet bowl devices 30 installed in the toilet room 21 and instructing the plurality of toilet bowl devices 30 to execute a predetermined operation or function will be described. The instruction determiner 64 determines timing to instruct the toilet bowl device 30 to execute predetermined operation or function based on the use situation information of the plurality of toilet bowl devices 30. The instruction transmitter 65 transmits an instruction to the toilet bowl device 30 at the timing determined by the instruction determiner 64 to execute the predetermined operation or function.
The control device 34 includes an instruction receiver 35, a sensor information acquirer 36, and a control unit 37. These functional blocks can be realized in various forms such as only hardware or a combination of hardware and software.
The instruction receiver 35 receives an instruction to execute the predetermined operation or function from the management device 50. The sensor information acquirer 36 acquires the detected information from various sensors such as the seating sensor, the temperature sensor, and the water level sensor that are provided in the toilet bowl device 30. The control unit 37 controls functions such as the drainage and private part cleaning of the toilet bowl device 30 based on the information detected by various sensors acquired by the sensor information acquirer 36, and also executes the predetermined operation or function based on the instruction received by the instruction receiver 35.
The instruction determiner 64 of the management device 50 refers to the past use situation of the toilet bowl device 30 held in the use situation information holder 73 to determine timing to instruct the toilet bowl device 30 to execute the predetermined operation or function. For example, the toilet bowl device 30 may be instructed to turn on a heating function of the toilet seat before a predetermined time when the facility 20 is opened. In addition, the toilet bowl device 30 may be instructed to turn off the heating function of the toilet seat before or after a predetermined time when the facility 20 is closed. The toilet bowl device 30 may be instructed to change the temperature of the toilet seat according to a date and time, a season, weather, outside temperature, room temperature, and the like.
When the instruction determiner 64 causes the plurality of toilet bowl devices 30 to execute a predetermined operation or function that consumes power of a predetermined value or more, the instruction determiner 64 determines timing to instruct the toilet bowl device 30 to execute the predetermined operation or function so that the predetermined number or more of the toilet bowl devices 30 do not execute the operation or function at the same time. For example, since the function of turning on a heater in the toilet seat requires relatively large power, the plurality of toilet bowl devices 30 may be instructed with a time difference so as not to exceed power supply capacity or contract amperage of the facility 20.
When the instruction determiner 64 causes the plurality of toilet bowl devices to execute a predetermined operation or function involving water supply or drainage, the instruction determiner 64 determines timing to instruct the toilet bowl device 30 to execute the predetermined operation or function so that the predetermined number or more of the toilet bowl devices 30 connected to the same water supply pipe or drainage pipe do not execute the operation or function at the same time. For example, since the function of cleaning the toilet bowl involves draining a relatively large amount of washing water, the plurality of toilet bowl devices 30 may be instructed with a time difference so as not to exceed the capacity of the drainage pipes installed in the toilet room 21 and the facility 20.
The instruction determiner 64 determines timing to instruct the toilet bowl device 30 to execute the predetermined operation or function involving the drainage so that among the plurality of toilet bowl devices 30 connected to the same drainage pipe, the toilet bowl device 30 connected to an upstream side of the drainage pipe has a drainage frequency, a time, or a drainage volume more than those of the toilet bowl device 30 connected to a downstream side thereof. In order to prevent a urine stone from adhering to the toilet bowl device 30 and clogging of the drainage pipe, in the case of regularly performing the function of cleaning the toilet bowl device 30, since drainage flows from the toilet bowl device 30 on the upstream side to the drainage pipe on the downstream side, sufficient drainage flows to the drainage pipe on the downstream side even if the cleaning frequency of the toilet bowl device 30 on the downstream side is low, but only drainage flows from the toilet bowl device 30 to the drainage pipe on the upstream side. Therefore, by increasing the cleaning frequency, the time, or the drainage volume of the toilet bowl device 30 connected to the drainage pipe on the upstream side more than those of the toilet bowl device 30 connected to the drainage pipe on the downstream side, it is possible to appropriately clean the drainage pipe on the upstream side and the drainage pipe on the downstream while suppressing washing water from being unnecessarily consumed.
According to such a technology, when the management device 50 collectively controls the plurality of toilet bowl devices 30 remotely, it is possible to reduce the malfunctions that can occur when a plurality of toilet bowl devices 30 perform the same function all at once and smoothly and appropriately cooperate and remotely control the plurality of toilet bowl devices 30.
In executing the predetermined operation or function, the control unit 37 of the toilet bowl device 30 inquires of the management device 50 whether or not other toilet bowl devices 30 executing the operation or function exist around the toilet bowl device 30. The responder 66 of the management device 50 acquires information on the executing operation or function from the plurality of toilet bowl devices 30 and stores the acquired information in the use situation information holder 73, checks whether other toilet bowl devices 30 that are executing the predetermined operation or function exist around the toilet bowl device 30 when the toilet bowl device 30 inquires whether or not other toilet bowl devices 30 that are executing the predetermined operation or function exist around the toilet bowl device 30, and returns a response to the check. The control unit 37 of the toilet bowl device 30 determines whether or not to execute the operation or function or timing to execute the operation or function according to the response from the management device 50. For example, in executing a predetermined operation or function involving drainage, the control unit 37 inquires of the management device 50 whether or not other toilet bowl devices 30 that are executing the operation or function exists around the toilet bowl device 30, and stops or postpones the execution of the operation or function when there is a response from management device 50 that the other toilet bowl devices 30 exist.
According to such a technology, even when each toilet bowl device 30 is operated independently, it is possible to reduce the malfunctions that may occur due to interference with the surrounding toilet bowl devices 30 and operate the toilet bowl devices 30 in appropriate cooperation with each other.
Next, as a feature of the management device 50 of some embodiments, a technology of instructing each toilet bowl device 30 to execute the predetermined operation or function will be described. The instruction determiner 64 determines the contents and timing of the predetermined operation or function executed by the toilet bowl device 30 based on the use situation information of the toilet bowl device 30. The instruction transmitter 65 transmits an instruction to the toilet bowl device 30 at the timing determined by the instruction determiner 64 to execute the operation or function of the determined contents.
The display device 81 displays a display screen generated by the control device 34. The speaker 82 outputs a sound generated by the control device 34. The display device 81 and the speaker 82 may be provided in a main body of the toilet bowl device 30, a washing water tank, or the like, may be provided on an inner wall of the private room 24, and may be provided on an inner side or an outer side of the door 25. The presenter 83 presents the information generated by each component of the control device 34 to a user via the display device 81 or the speaker 82.
First, a technology of solving a problem related to the use of the toilet bowl device 30 from the viewpoint of the user of the toilet bowl device 30 will be described.
The instruction determiner 64 instructs the toilet bowl device 30 to stop a cleaning drainage function of the toilet bowl device 30 when the abnormality detector 62 detects the abnormality of the toilet bowl device 30. When the instruction receiver 35 receives an instruction from the management device 50 to stop the cleaning drainage function, the control unit 37 of the toilet bowl device 30 stops the cleaning drainage function, and does not drain the washing water even when a toilet bowl cleaning lever or a toilet bowl flushing button is operated by a user.
As described above, the situation where a management subject, a cleaning subject, and maintenance subject of the toilet bowl device 30 as well as the user of the toilet bowl device 30 most want to avoid is the situation where sewage overflows from the toilet bowl device 30. According to the toilet management system 10 of some embodiments, when any abnormality is detected, particularly when the water level sensor or the like detects that the water level in the bowl is a predetermined value or greater, or when an abnormality that may be a cause of the overflowing of sewage such as the clogging of the toilet bowl device 30 is detected, the cleaning drainage function of the toilet bowl device 30 forcibly stops, and as a result, it is possible to prevent the sewage from overflowing from the toilet bowl device 30 and suppress the pollution due to the sewage to the minimum.
As described above, the abnormality detector 62 may detect an abnormality when the value of the water level sensor provided in the toilet bowl device 30 exceeds the predetermined value. In this way, it is possible to prevent the sewage from overflowing from the bowl by causing the toilet bowl device 30 to drain the washing water when the sewage actually overflows or is about to overflow. Further, the abnormality detector 62 may detect the abnormality based on the detection result of the sensor other than the water level sensor, the use situation information of the toilet bowl device 30, and the like. For example, the sensor that detects the sound or vibration may be installed near the drainage pipe, and the abnormality may be detected based on the detected sound or vibration after the cleaning drainage function is executed by the toilet bowl device 30. In this case, the abnormality detector 62 may detect the abnormality when the sound or vibration that should be generated when the sewage flows through the drainage pipe even if the cleaning drainage function is executed is not generated, previously hold reference data such as intensity, duration, frequency and pattern of the sound or vibration that normally occurs when the sewage flows through the drainage pipe, compare the sound or vibration actually detected by the sensor with the reference data, and detect the abnormality when the difference from the reference data exceeds the predetermined range. As a result, it is possible to accurately detect the abnormality of the drainage pipe or the like regardless of whether or not the water level of the toilet bowl device 30 is abnormal, and it is possible to prevent the sewage from overflowing from the bowl by causing the toilet bowl device 30 to drain the washing water.
The instruction determiner 64 may calculate the amount of washing water that can be added to the toilet bowl based on the value of the water level sensor without the overflowing of the sewage from the bowl, and limit the amount of washing water to the calculated amount of washing water to instruct the toilet bowl device 30 to execute the cleaning drainage function. As a result, it is possible to attempt to prevent the clogging of the drainage pipe by additionally introducing the washing water into the bowl while preventing the sewage from overflowing.
When the abnormality of the toilet bowl device 30, the clogging of the drainage pipe, or the like is detected while the toilet bowl device 30 is executing the cleaning drainage function, the instruction determiner 64 may instruct the toilet bowl device 30 to stop the executing cleaning drainage function. As a result, it is possible to minimize the overflowing of the sewage even during the execution of the cleaning drainage function.
When the abnormality of the clogging of the drainage pipe or the like is detected, the instruction determiner 64 may instruct all the toilet bowl devices 30 draining the sewage to the drainage pipe to stop the drainage function. As a result, even when the toilet bowl device 30 itself has no abnormality, it is possible to prevent the sewage from overflowing by causing the toilet bowl device 30 to drain the washing water.
(2) Presentation that Cleaning Drainage Function has Stopped
When the instruction determiner 64 instructs the toilet bowl device 30 to stop the drainage function, the instruction determiner 64 instructs the toilet bowl device 30 to cause the presenter 83 to present that the cleaning drainage function stops because the abnormality is detected. The presenter 83 of the toilet bowl device 30 presents the user with that the cleaning drainage function stops because the abnormality is detected via the display device 81 or the speaker 82. In this way, it is possible to prevent the user from using the toilet bowl device 30 even if the cleaning drainage function stops, and prevent the sewage from overflowing or the dirt from remaining in the bowl. As described above, the presenter 83 may present that the cleaning drainage function of the toilet bowl device 30 stops because the abnormality is detected by the abnormality notification means 27 installed inside or around the toilet room 21.
(3) Presentation that Abnormality Detection has been Notified
When the notifier 63 notifies the management subject terminal 40, the cleaning subject terminal 42, the manufacturing subject terminal 44, or the maintenance subject terminal 46 that the abnormality has been detected, the instruction determiner 64 instructs the toilet bowl device 30 to cause the presenter 83 to present that it has been notified that the abnormality has been detected. The presenter 83 of the toilet bowl device 30 presents to the user via the display device 81 or the speaker 82 that the appropriate notification destination has been notified that the abnormality has been detected. In this way, when the user notices the abnormality of the toilet bowl device 30, it is possible to inform the user that there is no need to contact the management subject or the like, the user can feel relieved, so it is possible to improve the convenience of the user and, it is possible to prevent repeated contact with the management subject or the like.
When the abnormality detector 62 detects the abnormality of the toilet bowl device 30 by the abnormality detector 62, the instruction determiner 64 instructs the toilet bowl device 30 to close a lid of the toilet bowl device 30. The control unit 37 of the toilet bowl device 30 automatically closes the lid of the toilet bowl device 30. Thereafter, when it is detected that the user manually opens the lid, the control unit 37 automatically closes the lid again after a predetermined time elapses from the opening of the lid. The control unit 37 may be locked so that the lid is not opened. In this way, when the abnormality occurs in the toilet bowl device 30 and dirt can remain in the bowl, the lid is automatically closed to minimize the spread of odors.
The instruction determiner 64 instructs a device for controlling locking/unlocking of a door for an entrance/exit of the toilet room 21 or the door 25 of the private room 24 to lock the door or the door 25 when the abnormality detector 62 detects the abnormality of the toilet bowl device 30. The device for controlling the locking/unlocking of the door of the entrance/exit or the door 25 may be provided in the door or the door 25, may be provided in the toilet bowl device 30, or may be provided in the toilet room 21. When instructed to lock the door or the door 25, the device for controlling the locking or unlocking of the door or the door 25 automatically locks the door or the door 25. At this time, in particular, when automatically locking the door of the entrance/exit of the toilet room 21, the toilet bowl device 30 or the abnormality notification means 27 may be instructed to present the information of another available toilet room 21, private room 24, or toilet bowl device 30 so as to guide the user. In this way, it is possible to prevent the user from entering the toilet room 21 or the private room 24 having the toilet bowl device 30 in which the abnormality is detected and using the toilet bowl device 30, so it is possible to improve the convenience of the user and improve the efficiency of the management, cleaning, and maintenance of the toilet bowl device 30.
The instruction determiner 64 instructs the toilet bowl device 30 to execute a deodorizing function of the toilet bowl device 30 when the abnormality detector 62 detects the abnormality of the toilet bowl device 30. The control unit 37 of the toilet bowl device 30 executes the deodorizing function. The deodorizing function is generally executed during or after the use of the toilet bowl device 30, and stops after a predetermined time elapses from the start of execution, but when the deodorizing function is automatically executed by the instruction from the management device 50, the measures for the abnormality are completed to make the toilet bowl device 30 return to the normal state, and the deodorization function continues until an instruction to stop is received from the management device 50, the management subject terminal 40, the cleaning subject terminal 42, the manufacturing subject terminal 44, or the maintenance subject terminal 46. As a result, it is possible to minimize the spread of odors generated by the occurrence of the abnormality.
The instruction determiner 64 instructs the toilet bowl device 30 to execute the cleaning drainage function when predetermined conditions are satisfied after stopping the cleaning drainage function of the toilet bowl device 30 because of the detection of the abnormality. The predetermined conditions are, for example, that the predetermined time elapses after the abnormality is detected, that the predetermined time elapses after the cleaning drainage function stops, that it is detected that the abnormalities such as the clogging of the drainage pipe are reduced or eliminated based on the use situation information of various sensors or equipment, and the like. As a result of the investigation by the applicant, it is known that most of the causes of the clogging of the drainage pipe in a toilet of a commercial facility, a public facility, or the like are due to the pouring of a large amount of toilet paper into the toilet at a time, but since the toilet paper is formed to be easily released in water, if the cleaning is made again after a while, the clogging due to the pouring of the toilet paper, which is the cause of the clogging of the drainage pipe may be eliminated. Therefore, the instruction determiner 64 instructs the toilet bowl device 30 to execute the cleaning drainage function and tries to clear the clogging of the drainage pipe when the predetermined time elapses after the abnormality is detected or after the toilet bowl device 30 is instructed to stop the cleaning drainage function. When it is detected that the clogging of the drainage pipe is eliminated by the re-cleaning, the instruction determiner 64 instructs the toilet bowl device 30 to withdraw the stop instruction of the cleaning drainage function and resume the normal operation, and instructs the toilet bowl device 30 and the abnormality notification means 27 to end the presentation that the abnormality has occurred, the cleaning drainage function has stopped, and the abnormality detection has been notified. When it is detected that the clogging of the drainage pipe is not eliminated even by the re-cleaning, the toilet bowl device 30 may be instructed to execute the cleaning drainage function after a predetermined time elapses. As a result, it is possible to eliminate the abnormality by automatically coping with most of the cases where the drainage pipe is clogged, so it is possible to significantly reduce the man-hours of the management subject, the cleaning subject, and the maintenance subject. Further, the abnormality of the toilet bowl device 30 can be eliminated early and the toilet bowl device 30 can be used, so it is possible to improve the convenience of the user.
The relationship with the problems between the control technology of the above toilet bowl device 30 and the use of toilet bowl device 30 from the viewpoint of the user will be described.
When the abnormality of the toilet bowl device 30 is found, the user thinks that he/she generates the abnormality while contacting the management subject or the like, or the user may hesitate to contact the management subject because he/she is afraid to lose his/her time due to reception of a question about the situation of the toilet bowl device 30 from the management agent. On the other hand, the user may feel anxious even if he/she leaves without contacting the management subject or the like. Such problems can be solved by the above-described abnormality detection/notification technology of the toilet, or (3) the presentation technology that the occurrence of the abnormality has been notified or the like among the individual toilet control technologies.
The user wants to avoid using the toilet bowl device 30 in which the abnormality has occurred or entering the toilet room 21 or the private room 24 in which the abnormality has occurred. Such problems can be solved by the above-described abnormality detection/notification technology of the toilet, or (2) the presentation technology that the cleaning drainage function has stopped or the like among the individual toilet control technologies.

Next, a technology of solving the problems related to the use of the toilet bowl device 30 from the viewpoint of the cleaning subject of the toilet bowl device 30 will be described.
As described above, since most of the causes of the clogging of the drainage pipe are that a large amount of toilet paper pours into the toilet at a time, the instruction determiner 64 instructs the toilet bowl device 30 to execute the cleaning drainage function when it is detected that a predetermined amount or more of toilet paper is used in order to reduce the pouring of a large amount of toilet paper into the toilet at one time. The control unit 37 of the toilet bowl device 30 executes the cleaning drainage function to forcedly pour the toilet paper into the drainage pipe. The use of the predetermined amount or more of toilet paper may be detected by, for example, the sensor installed in the toilet paper holder, or by a load cell, a passage sensor, a camera, or the like installed inside or near the bowl. In the former case, for example, the amount of the toilet paper used may be detected by detecting a rotation amount of roll-shaped toilet paper. In the latter case, the amount of toilet paper used is detected based on a weight of the toilet paper put into the bowl, the amount of toilet paper that passes through the passage sensor, an image obtained by capturing of the toilet paper put into the toilet bowl, or the like. When the cleaning drainage function is automatically executed, the presenter 83 may present to the user from the display device 81 or the speaker 82 that the cleaning drainage function is executed once because a large amount of toilet paper is used. In addition, the presenter 83 may alert the user from the display device 81 or the speaker 82 so that a large amount of toilet paper is not poured at a time. As a result, it is possible to reduce the situation where the drainage pipe is clogged due to the pouring of a large amount of toilet paper at a time, so it is possible to significantly suppress the occurrence of the abnormality in the toilet bowl device 30. Therefore, the man-hours of the management subject, the cleaning subject, and the maintenance subject can be significantly reduced, and the convenience of the user can be improved.
(9) Check if User is in Toilet in which Abnormality has Occurred
When the abnormality of the toilet bowl device 30 is detected by the abnormality detector 62, the notifier 63 checks whether the user is in the private room 24 in which the toilet bowl device 30 is installed based on the information acquired by the use situation information acquirer 61, and notifies the cleaning subject terminal 42 of the checked result. As a result, the cleaning subject can know whether or not it is possible to enter the private room 24 to clean the toilet bowl device 30 in which the abnormality occurs, so the cleaning efficiency can be improved. The instruction determiner 64 may instruct the toilet bowl device 30 to present the user to leave a room early because the cleaning subject enters the room for cleaning.
The relationship with the problems between the control technology of the above toilet bowl device 30 and the use of toilet bowl device 30 from the viewpoint of the cleaning subject will be described.
Even if the abnormality occurs in the toilet bowl device 30, the cleaning subject wants to suppress the overflow of sewage to the minimum.

As a further feature of the management device 50 of some embodiments, a technology of managing the timing or contents of the cleaning of the toilet room will be described. The cleaning instruction determiner 67 determines the timing or contents of the cleaning of the toilet room 21 based on the use situation information of the toilet bowl device 30. The cleaning instruction notifier 68 notifies the subject in charge of cleaning the toilet room 21 of the timing or contents determined by the cleaning instruction determiner 67.
The cleaning instruction determiner 67 refers to the use situation information holder 73 to determine the timing to clean the toilet room 21 so that the cleaning frequency of the toilet room 21 in which the installed toilet bowl device 30 is used more frequently is higher than that of the toilet room 21 in which the installed toilet bowl device 30 is used less frequently. The use frequency of the toilet bowl device 30 may be calculated from the information detected by the human sensor stored in the use situation information holder 73, the opening/closing state of the door 23 of the toilet room 21 and the door 25 of the private room 24, the use situation of the controller 31 or the drain lever, or the like. When a person in charge of cleaning cleans the toilet room 21 at the timing instructed by the management device 50, the cleaning subject terminal 42 transmits information indicating the cleaning state to the management device 50. The use situation information acquirer 61 stores the information indicating the cleaning state received from the cleaning subject terminal 42 in the use situation information holder 73. The cleaning instruction determiner 67 refers to the use situation information holder 73 to acquire the cleaning frequency of the toilet room 21.
The cleaning instruction determiner 67 may determine the contents of the cleaning of the toilet room 21 so that the number of items or a range of the cleaning of the toilet room 21 in which the installed toilet bowl device 30 is used more frequently is larger than that of the toilet room 21 in which the installed toilet bowl device 30 is used less frequently.
According to such a technology, by fulfilling the frequency and contents of the cleaning of the more frequently used toilet room 21, the cleaning frequency of the less frequently used toilet room 21 is suppressed while clearly maintaining the toilet room 21 where dirt is likely to occur, and as a result, it is possible to reduce the man-hours and burden on the person in charge of cleaning. In addition, since the cleaning frequency and contents of the toilet room 21 can be changed automatically and dynamically, the burden on the subject who manages the toilet room 21 can be reduced.
