Therefore, those skilled in the art will understand that these functional blocks can be implemented in various forms, such as hardware alone or a combination of hardware and software.

[0031] Usage status information acquisition unit 61 acquires usage status information of the toilet device 30 installed in the restroom 21 of facility 20 from communication device 22 and stores it in usage status information storage unit 73. Usage status information acquisition unit 61 acquires the following information as usage status information of the toilet device 30: information indicating the usage status of the toilet device 30; information indicating the operating status of controller 31; information indicating the opening and closing status of the door detected by the opening and closing sensor installed on the door 23 of restroom 21 or the door 25 of stall 24; information indicating the water level inside the toilet bowl detected by the water level sensor installed inside or outside the toilet bowl of toilet device 30 or urinal 32; information indicating the water level inside the washbasin detected by the water level sensor installed inside or outside the washbasin of sink 26; information indicating the water level inside the toilet device 30... Information on water leakage detected by a water leakage sensor installed around the urinal 32 or washbasin 26; information on the usage or status of equipment or machines such as lighting or ventilation fans installed inside or outside the toilet 21; information detected by sensors such as human body sensors, temperature sensors, and odor sensors installed inside or outside the toilet 21; information detected by sensors such as seat sensors, temperature sensors, and water level sensors installed in the toilet unit 30; images captured by a camera installed inside or outside the toilet 21; and sound acquired by a microphone installed inside or outside the toilet 21.

[0032] [Toilet Anomaly Detection Notification]

[0033] As a feature of the management device 50 in this embodiment, the following technology will first be explained: it detects abnormalities occurring in the toilet device 30 or the bathroom 21, and notifies the user of information related to the detected abnormalities. The abnormality detection unit 62 detects abnormalities in the toilet device 30 or in equipment or machines installed inside or around the bathroom 21 when the usage status information acquired by the usage status information acquisition unit 61 meets the specified conditions stored in the abnormality detection condition storage unit 75.

[0034] Figure 3 This represents an example of a condition stored in the anomaly detection condition storage unit 75. The anomaly detection condition storage unit 75 stores the types and contents of usage status information indicating conditions under which an anomaly should be determined to have occurred. Whenever usage status information is acquired by the usage status information acquisition unit 61, or periodically at predetermined times such as predetermined intervals, the anomaly detection unit 62 refers to the usage status information storage unit 73 and the anomaly detection condition storage unit 75 to determine whether usage status information meeting the conditions stored in the anomaly detection condition storage unit 75 has been acquired. If acquired, the unit instructs the notification unit 63 to notify the subject corresponding to the detected anomaly of the occurrence of the anomaly.

[0035] The notification unit 63, referring to the notification condition storage unit 76, determines the notification destination corresponding to the content of the anomaly detected by the anomaly detection unit 62, and notifies the determined notification destination of information related to the detected anomaly. In addition to notifying the error code indicating the type of anomaly, the notification unit 63 also notifies information necessary for studying the measures required for the notification destination. For example, the notification unit 63 may also notify information indicating the status of the toilet device 30 or the bathroom 21, or images of the toilet device 30 or the bathroom 21. The notification unit 63 can directly notify the terminal of the subject to be notified of the information related to the detected anomaly, or send it to the company or office's switchboard or direct line, or send an email to an email address, or notify the responsible person's mobile phone number and email address. The notification unit 63 records the notification date, notification destination, notification content, and other information in the notification history storage unit 74. When a response is received from the notification destination, the notification unit 63 displays it on the display device 52. The notification unit 63 records the presence or absence of a response, the response date, and the response content in the notification history storage unit 74.

[0036] Figure 4This represents an example of the conditions stored in the notification condition storage unit 76. The notification condition storage unit 76 stores the error code indicating the type of anomaly that occurred, the subject of the anomaly that should be notified, and the priority order of notifications accordingly. When an anomaly is detected by the anomaly detection unit 62, the notification unit 63 refers to the notification condition storage unit 76 to obtain the notification destination of the anomaly that should be notified, and refers to the toilet information database 71 and the notification destination information database 72 to obtain the information of the notification destination. The notification unit 63 notifies the earlier notification destinations according to the priority order of notifications. If no response is received from the earlier notification destinations, or if calls are not answered, the notification unit 63 may notify the later notification destinations, or may attempt to notify the earlier notification destinations multiple times, or may perform both in parallel. The notification unit 63 may also notify multiple notification destinations simultaneously.

[0037] The following provides specific examples of the detected anomalies and the destination of the notification.

[0038] The anomaly detection unit 62 can also determine that an anomaly has occurred if the usage status information indicating the usage status of the toilet device 30 meets the conditions stored in the anomaly detection condition storage unit 75. For example, the anomaly detection unit 62 can also determine that an anomaly has occurred when it receives information indicating that the water level inside the toilet bowl of the toilet device 30 exceeds a predetermined value. When sewage overflows from the toilet bowl due to blockage of the drain pipe, it can have a significant impact not only on the interior of the toilet 21 but also on the surrounding area. Therefore, it is very important to have a system in place to notify the appropriate parties in advance so that sewage overflow can be detected quickly and necessary measures can be taken in the operation of facilities.

[0039] The amount of water inside the toilet bowl of the toilet device 30 can also be detected using a water level sensor installed on the inner or outer surface of the bowl. When the water level sensor is installed on the outer surface of the bowl, a non-contact water level sensor, such as an electrostatic capacitive type, can also be used. Alternatively, a non-contact water level sensor, such as an electrostatic capacitive type, can be installed on the outer surface of the trap between the drain outlet and the drain pipe at the lower part of the bowl. Even after using the toilet device 30, if water remains in the bowl below the upper part of the trap after rinsing with flushing water and draining the wastewater, and the water level sensor installed on the outer surface of the trap detects water remaining in the upper part of the trap even after a predetermined time has passed, it can be inferred that the wastewater in the bowl has not been drained from the drain pipe due to blockage or other reasons, and therefore, an abnormality can be determined.

[0040] In cases where sewage overflows from the toilet bowl, measures are needed to temporarily restrict cleaning of the toilet 21 and access to the toilet 21 and its surrounding area. Therefore, the notification unit 63 notifies the entity responsible for cleaning the toilet 21 where the malfunctioning toilet unit 30 is installed and the entity managing the toilet 21 of the occurrence of the malfunction. Furthermore, if, based on other information, it is presumed that the malfunction is caused by a faulty machine such as the toilet unit 30, the entity that manufactured the malfunctioning toilet unit 30 may also be notified of the occurrence of the malfunction, requesting information on the malfunctioning machine or equipment, or ordering spare parts. Additionally, if, based on other information, it is presumed that the malfunction is caused by a faulty machine or equipment such as a drain pipe or pump, the entity responsible for maintaining these machines or equipment may also be notified of the occurrence of the malfunction, requesting repair or replacement of the machines or equipment.

[0041] The notification unit 63 can also notify the main entity managing the floor where the toilet 21 is located, as well as the main entity managing the floor below it, or nearby shops, of the abnormality when the toilet 21 overflows from the toilet bowl, in addition to the main entity managing the floor where the toilet 21 is located. In the event of actual sewage overflow, there is a possibility that the sewage may spread on the floor of the toilet 21 and seep into the back of the ceiling below, or leak from the ceiling below. Therefore, by also notifying the entities managing the floor below or the surrounding area of ​​the abnormality in advance, necessary measures can be taken quickly, minimizing the impact.

[0042] The notification unit 63 can also notify the anomaly reporting device 27 installed inside or around the restroom 21 of the occurrence of an anomaly. This allows users who intend to enter the restroom 21 or those using facilities 20 surrounding the restroom 21 to be notified of the anomaly, preventing them from entering or prompting them to leave the area around the restroom 21. Furthermore, it enables managers of shops or other establishments located around the restroom 21 to take appropriate measures such as ventilation or alarm activation. Additionally, it allows the manager responsible for inspecting the restroom 21 to be promptly notified of the anomaly.

[0043] This technology significantly reduces the time required from the occurrence of an anomaly to the implementation of appropriate measures, thus minimizing the impact of the anomaly. Furthermore, proper maintenance and management of the restroom 21 improves the convenience for users of the facility 20, as well as its comfort and operational status.

[0044] The anomaly detection unit 62 can also determine that an anomaly has occurred if the usage status information indicating the operation status of the controller 31, which represents the user's input of operation instructions to the toilet device 30, meets the conditions stored in the anomaly detection condition storage unit 75. For example, the anomaly detection unit 62 can also determine that an anomaly has occurred when it receives information indicating that the same button on the controller 31 has been operated multiple times consecutively. When a button used to perform a function is operated multiple times consecutively, it is generally not assumed that the function has been performed multiple times consecutively. It is speculated that there is a malfunction in the button or in the configuration used to perform the function, preventing the user from performing the expected function. Therefore, it can also be determined that the controller 31 or the toilet device 30 operated by the controller 31 has malfunctioned. The anomaly detection condition storage unit 75 can also establish and store the types of operable buttons, the number of times the button determined to have malfunctioned has been operated, and the interval between the operation of the buttons determined to have been operated consecutively, as conditions. For buttons that are assumed to have been operated multiple times consecutively, such as the button used to change the volume of the toilet sound effect device, the number of times the button determined to have malfunctioned has been operated may be more than that of other buttons.

[0045] If the seat sensor of the toilet device 30 does not detect that the user is seated, but receives information indicating that the button for performing the local cleaning function has been pressed, it is presumed that the seat sensor or the button has malfunctioned, and therefore it can be determined that an abnormality has occurred.

[0046] If the button indicating that the partial cleaning function of the toilet device 30 has not been pressed for a specified time after receiving information that the partial cleaning function has been activated, it is inferred that the partial cleaning function or the button has malfunctioned, and therefore it can be determined that an abnormality has occurred.

[0047] If, during the periodic communication between the controller 31 and the toilet device 30, information is received indicating that communication between the controller 31 and the toilet device 30 cannot be maintained for a specified period of time, it can be inferred that the communication function of the controller 31 or the toilet device 30 has malfunctioned, or that the controller 31 has fallen or been pulled out of the range where it can communicate with the toilet device 30, or that the battery of the controller 31 is low. Therefore, it can also be determined that an abnormality has occurred.

[0048] The notification unit 63 notifies the main body of the toilet 21 where the controller 31 or toilet device 30 is installed, as well as the main body responsible for the maintenance of the controller 31 or toilet device 30, of the occurrence of the abnormality. Additionally, if it is presumed, based on other information, that the controller 31 or toilet device 30 requires repair or replacement, the unit may also notify the main body that manufactures the controller 31 or toilet device 30 of the occurrence of the abnormality and order the necessary parts.

[0049] In this way, based on the operating status of the controller 31, abnormalities that would be difficult for the management to discover even when inspecting the restroom 21 can be quickly detected and notified, and necessary measures can be taken. Therefore, the convenience of users of the restroom 21 can be improved, and the comfort or operating status of the facility 20 can be improved.

[0050] If the function of changing the temperature of the toilet seat and the temperature of the warm water used for local cleaning is stopped by the administrator, and if information is received indicating that the button for changing the temperature has been operated more than a specified number of times, the main body of the toilet management 21 will be notified that many users want to change the temperature.

[0051] In this way, the user's requirements for the toilet device 30 can be estimated based on the operation status of the controller 31 and notified to the management body, thereby improving the environment of the toilet 21 and increasing the convenience for the user.

[0052] The anomaly detection unit 62 can also determine that an anomaly has occurred if the usage information indicating the status of equipment or machines installed inside or around the restroom 21 meets the conditions stored in the anomaly detection condition storage unit 75. For example, the anomaly detection unit 62 can also determine that an anomaly has occurred when it receives information indicating that the time from when the door 23 of the restroom 21 or the door 25 of the stall 24 is closed to when it is reopened is less than a predetermined value. The anomaly detection unit 62 can also calculate statistical values ​​such as the average dwell time based on the historical dwell time of each stall 24, each restroom 21, or each facility 20, and calculate a predetermined value for determining that an anomaly has occurred.

[0053] If a user remains in restroom 21 or stall 24 for an extended period, and there are concerns about the user's health, the notification unit 63 notifies the main entity responsible for managing restroom 21 of the occurrence of the anomaly and promptly proceeds to restroom 21. Additionally, if based on other information, it is determined that door 23 or door 25 is malfunctioning, or that the opening / closing sensor for door 23 or door 25 is malfunctioning, the unit responsible for the maintenance of restroom 21 is notified of the anomaly. Furthermore, if based on other information, it is determined that door 23, door 25, or the opening / closing sensor requires repair or replacement, the unit also notifies the main entity that manufactures door 23, door 25, or the opening / closing sensor of the anomaly and orders the necessary parts.

[0054] Therefore, even if an abnormality occurs in the user of toilet 21, appropriate measures can be quickly detected and taken. As a result, users can use toilet 21 and facility 20 with peace of mind, and the comfort and operation of facility 20 are improved. In addition, not only can abnormalities of toilet device 30 be quickly detected, but also abnormalities of equipment or machines installed inside or around toilet 21 can be quickly detected. Therefore, toilet 21 can be properly maintained and managed.

[0055] The anomaly detection unit 62 can also determine that an anomaly has occurred in the toilet device 30 or any equipment or machine installed inside or around the toilet 21 if any two or more combinations of information stored in the usage status information storage unit 73 meet the prescribed conditions. The notification unit 63 can also notify the entity responsible for the management of the toilet 21 of the occurrence of the anomaly and, if it is suspected that the equipment or machine needs repair or replacement, entrust the entity responsible for the maintenance of the equipment or machine to repair or replace it, and order the necessary parts from the entity that manufactures the equipment or machine.

[0056] If information is received indicating that the door 23 of the toilet 21 or the door 25 of the stall 24 has been closed for a specified period of time and the toilet device 30 installed in the toilet 21 or the stall 24 has not been used for a specified period of time, or if information is received indicating that the door 23 of the toilet 21 or the door 25 of the stall 24 has not been opened even after a specified period of time has passed since the toilet device 30 was used, it is suspected that an abnormality has occurred, and therefore it can be determined that an abnormality has occurred.

[0057] If the toilet device 30 is not used until a specified time has elapsed after the door 23 of the toilet 21 or the door 25 of the stall 24 is closed, it is presumed that the toilet device 30 is malfunctioning, or that the toilet device 30, the stall 24, or the toilet 21 is dirty and cannot be used. Therefore, it can also be determined that an abnormality has occurred.

[0058] If information is received indicating that the door 25 of the single room 24 is open and the toilet device 30 is in use, it is inferred that the door 25 opening / closing sensor or the toilet device 30 is malfunctioning, and therefore, it can be determined that an abnormality has occurred.

[0059] If the toilet device 30 has not been used for a specified period of time, it can also be determined that the toilet device 30 or the toilet 21 on which the toilet device 30 is installed has malfunctioned. The specified period of time can be calculated based on the past usage frequency of the toilet device 30 or the toilet 21.

[0060] In a toilet device 30 equipped with a hot water tank for partial cleaning, if the temperature of the warm water in the hot water tank does not change above a specified value even though the partial cleaning function is performed, it is suspected that the valve of the hot water tank or the partial cleaning nozzle has malfunctioned, and therefore it can be determined that an abnormality has occurred.

[0061] Anomaly detection conditions, as in the example above, can also be automatically obtained through machine learning. For instance, information on the content of anomalies and their usage status at the time of occurrence can be collected from multiple facilities 20, toilets 21, and toilet units 30. This actual data can be used as training data to perform training-based learning, thereby learning the correlation between usage status information and anomaly content. This machine learning can be performed by a server device or by a large number of computers using technologies such as cloud computing. The completed learning conditions can be sent to the management device 50 at any time and stored in the anomaly detection condition storage unit 75. The management device 50 can also have a learning unit that performs machine learning. In this case, the learning unit can obtain information on whether an anomaly has actually occurred from the notification destination of the anomaly notification detected by the anomaly detection unit 62. If an anomaly has occurred, it can obtain information such as the content of the anomaly, the status of the toilet 21 or toilet unit 30, the measures taken, and the results of the measures. This information, along with the usage status information at the time the anomaly was determined to have occurred, can be used as training data to perform training-based learning, thereby further learning the anomaly detection conditions and updating the anomaly detection condition storage unit 75.

[0062] Thus, according to the technology of this embodiment, even if an anomaly occurs in the toilet 21 or the toilet device 30, it can be quickly detected and the appropriate notification destination can be notified, and the necessary measures can be taken, thereby minimizing the impact of the anomaly. Furthermore, since the occurrence of anomalies can be detected based on information collected from the toilet 21 or the toilet device 30, the cost of resetting sensors used for anomaly detection can be reduced.

[0063] Coordinated control of multiple toilet devices

[0064] Next, as a feature of the management device 50 of this embodiment, a technique for uniformly managing multiple toilet devices 30 installed in the restroom 21 and instructing the multiple toilet devices 30 to perform a prescribed action or function will be described. The instruction determination unit 64 determines the timing for instructing the toilet devices 30 to perform a prescribed action or function based on usage information of the multiple toilet devices 30. At the timing determined by the instruction determination unit 64, the instruction sending unit 65 sends an instruction to perform the prescribed action or function to the toilet devices 30.

[0065] Figure 5The configuration of the toilet device according to the embodiment is shown. The toilet device 30 includes a communication device 33 and a control device 34. The communication device 33 controls communication with other devices. The communication device 51 can also communicate via any wired or wireless communication method. The communication device 51 communicates with the communication device 22 via wireless communication, sends usage status information of the toilet device 30 to the management device 50, and sends instructions for the toilet device 30 from the management device 50.

[0066] The control device 34 includes an instruction receiving unit 35, a sensor information acquisition unit 36, and a control unit 37. These functional blocks can be implemented in various forms, such as hardware only or a combination of hardware and software.

[0067] The instruction receiving unit 35 receives instructions from the management device 50 to perform a prescribed action or function. The sensor information acquisition unit 36 ​​acquires information detected by various sensors installed on the toilet device 30, such as a seat sensor, temperature sensor, and water level sensor. Based on the information acquired by the sensor information acquisition unit 36 ​​and detected by the various sensors, the control unit 37 controls the drainage, partial cleaning, and other functions of the toilet device 30, and performs the prescribed action or function based on the instructions received by the instruction receiving unit 35.

[0068] The instruction decision unit 64 of the management device 50 refers to the past usage data of the toilet device 30 stored in the usage information storage unit 73 to determine when to instruct the toilet device 30 to perform a prescribed action or function. For example, it may instruct the toilet device 30 to turn on the heated toilet seat function before a predetermined time when the facility 20 opens. Alternatively, it may instruct the toilet device 30 to turn off the heated toilet seat function before or after a predetermined time when the facility 20 closes. It may also instruct the toilet device 30 to change the temperature of the toilet seat based on the day, season, weather, outside temperature, or indoor temperature.

[0069] When multiple toilet units 30 are required to perform a specified action or function that consumes more than a specified amount of electricity, the instruction determination unit 64 determines the timing for instructing the toilet units 30 to perform the specified action or function in such a way that a specified number or more toilet units 30 do not perform the action or function simultaneously. For example, turning on the toilet seat heater requires a large amount of electricity, so the instruction can be given to multiple toilet units 30 at a time difference, in a manner that does not exceed the power supply capacity of the facility 20 and the contracted amperage.

[0070] When multiple toilet devices are instructed to perform a prescribed action or function that accompanies water supply or drainage, the instruction decision unit 64 determines the timing for instructing the toilet device 30 to perform the prescribed action or function in a manner that prevents a predetermined number of toilet devices 30 connected to the same water supply or drainage pipe from performing the same action or function simultaneously. For example, the function of flushing the toilet is accompanied by the drainage of a relatively large amount of flushing water; therefore, the instruction can be given to multiple toilet devices 30 at a time difference, in a manner that does not exceed the capacity of the drainage pipe installed in the toilet 21 and the facility 20.

[0071] The instruction determination unit 64 determines when to instruct the toilet device 30 to perform a prescribed action or function accompanying drainage, based on the frequency, duration, or volume of drainage of the toilet device 30 connected to the upstream side of the drain pipe among the multiple toilet devices 30 connected to the same drain pipe. When the function of periodically cleaning the toilet device 30 is performed to prevent urinary stones from adhering to the toilet device 30 or to prevent blockage of the drain pipe, drainage from the upstream toilet device 30 also flows into the downstream drain pipe. Therefore, even if the cleaning frequency of the downstream toilet device 30 is lower, sufficient drainage flows into the downstream drain pipe, but only drainage from the upstream toilet device 30 flows into the upstream drain pipe. Thus, compared to the toilet device 30 connected to the downstream drain pipe, the cleaning frequency, duration, or volume of the toilet device 30 connected to the upstream drain pipe is increased, thereby suppressing wasteful cleaning water consumption and properly cleaning both the upstream and downstream drain pipes.

[0072] According to this technology, when the management device 50 remotely controls multiple toilet devices 30 at the same time, it can reduce the adverse situations that may occur when multiple toilet devices 30 perform the same function at the same time, and smoothly and appropriately coordinate the remote control of multiple toilet devices 30.

[0073] When the control unit 37 of the toilet device 30 performs a prescribed action or function, it queries the management device 50 to inquire whether other toilet devices 30 performing the same action or function are nearby. After obtaining information related to the currently performed action or function from multiple toilet devices 30 and storing it in the usage status information storage unit 73, when the toilet device 30 queries whether other toilet devices 30 performing the prescribed action or function are nearby, the response unit 66 of the management device 50 confirms and answers whether other toilet devices 30 performing the prescribed action or function are nearby. Based on the response from the management device 50, the control unit 37 of the toilet device 30 determines whether the action or function can be performed or the timing of such execution. For example, when performing a prescribed action or function accompanied by drainage, the control unit 37 queries the management device 50 to inquire whether other toilet devices 30 performing the same action or function are nearby. If the management device 50 answers that they exist, the execution of the action or function is suspended or postponed.

[0074] According to this technology, even when each toilet device 30 operates independently, it is possible to reduce adverse situations that may arise from interference with surrounding toilet devices 30 and to operate in a properly coordinated manner.

[0075] [Control of each toilet device]

[0076] Next, as a feature of the management device 50 in this embodiment, the technique of instructing each toilet device 30 to perform a predetermined action or function will be described. The instruction determination unit 64 determines the content and timing of the action or function to be performed by the toilet device 30 based on usage information of the toilet device 30. The instruction sending unit 65 sends an instruction to perform the determined action or function to the toilet device 30 at the timing determined by the instruction determination unit 64.

[0077] Figure 6 This figure illustrates the configuration of the toilet device 30 according to the embodiment. The toilet device 30 shown in this figure, besides... Figure 5 In addition to the components of the toilet device 30 shown, it also includes a display device 81 and a speaker 82. Furthermore, the control device 34 of the toilet device 30 shown in this figure, besides... Figure 5 In addition to the control device 34, the toilet device 30 shown also includes a prompting unit 83.

[0078] The display device 81 displays the screen generated by the control device 34. The speaker 82 outputs the sound generated by the control device 34. The display device 81 and the speaker 82 can be installed on the main body of the toilet device 30 or the washbasin, or on the inner wall of the cubicle 24, or on the inside or outside of the door 25. The prompting unit 83 prompts the user with the information generated by the various components of the control device 34 via the display device 81 or the speaker 82.

[0079] First, the technology used to solve problems related to the use of the toilet device 30 from the perspective of the user of the toilet device 30 will be explained.

[0080] (1) Stop the cleaning and drainage function

[0081] When the anomaly detection unit 62 detects an anomaly in the toilet device 30, the instruction decision unit 64 instructs the toilet device 30 to stop its flushing and drainage function. When the instruction receiving unit 35 receives the instruction to stop the flushing and drainage function from the management device 50, the control unit 37 of the toilet device 30 stops the flushing and drainage function, and no flushing water will be discharged even if the user operates the toilet flushing control lever or the toilet flushing button.

[0082] As mentioned above, the situation of sewage overflowing from the toilet device 30 is something that should be avoided by both the user of the toilet device 30 and the management, cleaning, and maintenance personnel of the toilet device 30. According to the toilet management system 10 of this embodiment, when certain abnormalities are detected, especially when the water level in the toilet bowl is detected to be above a certain value by a water level sensor or the like, or when an abnormality such as a blockage in the drain pipe that may cause sewage overflow is detected, the flushing and drainage function of the toilet device 30 is forcibly stopped. Therefore, sewage can be prevented from overflowing from the toilet device 30 in the future, and pollution caused by sewage can be suppressed to a minimum.

[0083] As described above, the anomaly detection unit 62 can also detect an anomaly when the value of the water level sensor on the toilet device 30 exceeds a predetermined value. Thus, in the event that sewage is actually overflowing or about to overflow, flushing water can be discharged through the toilet device 30 to prevent sewage from overflowing from the toilet bowl. Furthermore, the anomaly detection unit 62 can also detect anomalies based on the detection results of sensors other than the water level sensor or information about the usage status of the toilet device 30. For example, a sensor for detecting sound or vibration can be installed near the drain pipe, and anomalies can be detected based on the sound or vibration detected after the toilet device 30 performs the flushing and flushing function. In this case, the anomaly detection unit 62 can detect an anomaly even if the flushing and flushing function has been performed but the sound or vibration that should be generated when sewage flows through the drain pipe is not generated. Alternatively, it can pre-store reference data such as the intensity, duration, frequency, and type of sound or vibration that is typically generated when sewage flows through the drain pipe, and compare the sound or vibration actually detected by the sensor with the reference data, detecting an anomaly when the difference from the reference data exceeds a predetermined range. Therefore, regardless of whether the water level in the toilet device 30 is abnormal, abnormalities in the drain pipe and other components can be accurately detected, and cleaning water can be discharged through the toilet device 30, thus preventing sewage from overflowing from the toilet bowl.

[0084] The instruction determination unit 64 can also instruct the toilet device 30 to calculate, based on the value of the water level sensor, the amount of cleaning water that can be added to the toilet bowl without causing sewage to overflow, and perform the cleaning and drainage function by limiting the amount of cleaning water to the calculated amount. This prevents sewage overflow and attempts to determine whether the blockage in the drain pipe can be eliminated by adding cleaning water to the toilet bowl.

[0085] The instruction decision unit 64 can also instruct the toilet device 30 to stop the ongoing cleaning and drainage function if it detects an abnormality in the toilet device 30 or a blockage in the drain pipe during the operation of the cleaning and drainage function. As a result, even during the operation of the cleaning and drainage function, the overflow of sewage can be minimized.

[0086] The instruction decision unit 64 can also instruct all toilet devices 30 that discharge sewage into the drain pipe to stop the drainage function if an abnormality such as a blockage is detected in the drain pipe. Thus, even if there is no abnormality in the toilet device 30 itself, sewage overflow can be prevented by discharging flushing water from the toilet device 30.

[0087] (2) A prompt indicating that the cleaning and drainage function has stopped.

[0088] When the instruction decision unit 64 instructs the toilet device 30 to stop the flushing function, it instructs the prompt unit 83 to notify the toilet device 30 that the flushing and drainage function has been stopped due to an abnormality detected. The prompt unit 83 of the toilet device 30 notifies the user of the stoppage of the flushing and drainage function via the display device 81 or the speaker 82. This prevents the user from using the toilet device 30 even though the flushing and drainage function has been stopped, and prevents sewage overflow or residue from remaining in the toilet bowl. As described above, the prompt unit 83 can also use an abnormality detection device 27 installed inside or around the toilet 21 to notify the user that the flushing and drainage function of the toilet device 30 has been stopped due to an abnormality detected.

[0089] (3) A notification indicating that the anomaly detection has been completed.

[0090] When the notification unit 63 notifies the management terminal 40, cleaning terminal 42, manufacturing terminal 44, or maintenance terminal 46 that an anomaly has been detected, the instruction decision unit 64 instructs the toilet device 30 to notify the prompt unit 83 that the notification of the anomaly detection has been completed. The prompt unit 83 of the toilet device 30 notifies the user via the display device 81 or the speaker 82 that the notification of the anomaly detection has been completed to the appropriate notification destination. Therefore, when the user notices an anomaly in the toilet device 30, the user is informed that there is no need to contact the management unit, etc., thus providing peace of mind, improving user convenience, and preventing repeated contact with the management unit, etc.

[0091] (4) Automatic closing of the lid

[0092] When the anomaly detection unit 62 detects an anomaly in the toilet device 30, the instruction decision unit 64 instructs the toilet device 30 to close its lid. The control unit 37 of the toilet device 30 automatically closes the lid. Then, when it detects that the user has manually opened the lid, the control unit 37 automatically closes the lid again after a predetermined time has elapsed since it was opened. The control unit 37 can also lock the lid without opening it. Thus, in the event of an anomaly in the toilet device 30 and the possibility of waste remaining in the toilet bowl, the spread of foul odors can be minimized by automatically closing the lid.

[0093] (5) Automatic locking of doors and windows

[0094] When the anomaly detection unit 62 detects an anomaly in the toilet device 30, the instruction decision unit 64 instructs the locking and unlocking device of the door / window or stall 24 to lock the entrance / exit doors / windows of the toilet 21 or the door 25 of the stall 24. The locking and unlocking device of the entrance / exit doors / windows or stall 25 can be installed on the door / window or stall 25, on the toilet device 30, or on the toilet 21. When locking is instructed, the locking and unlocking device of the door / window or stall 25 automatically locks the door / window or stall 25. At this time, especially when the entrance / exit doors / windows of the toilet 21 are automatically locked, the toilet device 30 or the anomaly reporting device 27 can also be instructed to provide information about other toilets 21, stalls 24, or toilet devices 30 that can be used, and to guide the user. Therefore, it is possible to prevent users from entering the toilet 21 or stall 24 where the toilet device 30 has been detected as abnormal and using the toilet device 30. Thus, user convenience can be improved, and the efficiency of management, cleaning, and maintenance of the toilet device 30 can be increased.

[0095] (6) Automatic deodorization

[0096] When the anomaly detection unit 62 detects an anomaly in the toilet device 30, the instruction decision unit 64 instructs the toilet device 30 to perform the deodorization function. The control unit 37 of the toilet device 30 then performs the deodorization function. The deodorization function is normally performed during or after use of the toilet device 30 and stops after a predetermined time. However, if the deodorization function is automatically performed upon instruction from the management device 50, it continues until measures to address the anomaly are completed and the toilet device 30 returns to normal operation, and an instruction to stop is received from the management device 50, management main terminal 40, cleaning main terminal 42, manufacturing main terminal 44, or maintenance main terminal 46. This minimizes the spread of foul odors caused by the anomaly.

[0097] (7) Wash again

[0098] When the toilet device 30's flushing and drainage function is stopped due to an detected anomaly, and the prescribed conditions are met, the instruction decision unit 64 instructs the toilet device 30 to perform the flushing and drainage function. The prescribed conditions may be, for example: a predetermined time has elapsed since the anomaly was detected; a predetermined time has elapsed since the flushing and drainage function was stopped; or anomalies such as drainage pipe blockage being reduced or eliminated based on usage information from various sensors or machines. According to the results of the applicant's investigation, most drainage pipe blockages in commercial or public facilities are caused by the large-volume flow of disposable toilet paper. However, toilet paper tends to disperse easily in water, so when flushed again shortly afterward, the blockage may be cleared by the flow of toilet paper. Therefore, when an anomaly is detected, or a predetermined time has elapsed since the toilet device 30 was instructed to stop the flushing and drainage function, the instruction decision unit 64 instructs the toilet device 30 to perform the flushing and drainage function and attempts to eliminate the drainage pipe blockage. When a flushing operation is detected to clear a blockage in the drain pipe, the instruction decision unit 64 instructs the toilet unit 30 to withdraw the stop instruction for the flushing and drainage function and resume normal operation. It also instructs the toilet unit 30 and the fault reporting device 27 to end the operation by indicating that an abnormality is occurring, the flushing and drainage function is stopped, or that the fault detection has been completed. If a flushing operation fails to clear the blockage in the drain pipe, the toilet unit 30 can be instructed to resume the flushing and drainage function after a predetermined time. This allows for the automatic handling and elimination of most drain pipe blockages, significantly reducing the workload of the management, cleaning, and maintenance units. Furthermore, by eliminating faults in the toilet unit 30 as early as possible, the toilet unit 30 becomes usable, thus improving user convenience.

[0099] Regarding the control technology of the toilet device 30 described above, its relationship with issues related to the use of the toilet device 30 from the user's perspective will be explained.

[0100] When users discover an abnormality in the toilet device 30, they may hesitate to contact the management, feeling that they caused the abnormality or worrying about being questioned by the management about the condition of the toilet device 30, thus wasting time. On the other hand, some users may feel uneasy leaving without contacting the management. Such issues can be resolved through the aforementioned toilet abnormality detection and notification technology and the technology in each toilet's control system, such as (3) the technology that indicates that an abnormality has been notified.

[0101] Users want to avoid using toilet fixture 30 that has malfunctioned, or entering bathroom 21 or stall 24 that has malfunctioned. Such problems can be solved by the above-mentioned toilet malfunction detection and notification technology and the technology in each toilet control system, such as (2) the technology that prompts that the flushing and drainage function has stopped.

[0102] In the event of a malfunction in the toilet device 30 and waste remains in the toilet bowl, the user must avoid seeing the waste of others or allowing others to see their own waste. This problem can be solved by the aforementioned toilet malfunction detection and notification technology and various toilet control technologies, such as (4) automatic lid closing technology and (5) automatic door and window locking technology.

[0103] In the event of a malfunction in the toilet device 30, the user wishes to avoid sewage overflow due to their use of the toilet device 30. This problem can be solved by the aforementioned toilet malfunction detection and notification technology and the technology of stopping the flushing and drainage function in the control technology of each toilet.

[0104] In the event of a malfunction in the toilet fixture 30, the user wishes to reduce the odor in the restroom 21 and the individual stall 24. This issue can be addressed through the aforementioned toilet malfunction detection and notification technology and the automatic deodorization technology, among other toilet control technologies, including (6).

[0105] In the event of abnormalities such as blockages in the drain pipe, users want to eliminate the abnormality as soon as possible and make the toilet device 30 usable. Such problems can be solved by the above-mentioned toilet abnormality detection and notification technology and the re-cleaning technology in the control technology of each toilet, such as (7).

[0106] Next, the technology used to solve problems related to the use of the toilet device 30 from the viewpoint of the cleaning body of the toilet device 30 will be explained.

[0107] (8) Automatic cleaning corresponding to the amount of toilet paper used

[0108] As mentioned above, the main cause of drain blockage is the excessive use of toilet paper at once. Therefore, to reduce the excessive use of toilet paper at once, the instruction decision unit 64 instructs the toilet device 30 to perform the flushing and draining function when it detects that a prescribed amount of toilet paper has been used. The control unit 37 of the toilet device 30 performs the flushing and draining function and forcibly circulates toilet paper into the drain pipe. For example, a sensor installed on the toilet paper holder can be used to detect that a prescribed amount of toilet paper has been used, or a load sensor installed inside or near the toilet bowl, a sensor, a camera, etc. can be used to detect that a prescribed amount of toilet paper has been used. In the former case, for example, the amount of toilet paper used can be detected by detecting the amount of rotation of the toilet paper roll. In the latter case, the amount of toilet paper used can be detected by the weight of the toilet paper put into the toilet bowl, the amount of toilet paper passing through the sensor, or an image of the toilet paper put into the toilet bowl. The prompt unit 83 can also prompt the user from the display device 81 or the speaker 82 when the flushing and draining function is automatically performed, indicating that the flushing and draining function is temporarily performed due to the excessive use of toilet paper. Furthermore, the prompting unit 83 can also remind the user via the display device 81 or the speaker 82 to prevent the toilet paper from flowing out in large quantities at once. This reduces the likelihood of drain blockages caused by excessive toilet paper flow, thus significantly reducing the occurrence of malfunctions in the toilet system 30. Consequently, it greatly reduces the workload of the management, cleaning, and maintenance units, and improves user convenience.

[0109] (9) Confirm whether the user is in a toilet where an abnormality has occurred.

[0110] When the anomaly detection unit 62 detects an anomaly in the toilet device 30, the notification unit 63, based on information obtained from the usage status information acquisition unit 61, confirms whether the user is in the stall 24 where the toilet device 30 is installed, and notifies the cleaning unit terminal 42 of the confirmation result. Thus, the cleaning unit can know whether it can enter the stall 24 to clean the malfunctioning toilet device 30, thereby improving cleaning efficiency. The instruction decision unit 64 can also instruct the toilet device 30 to leave as soon as possible because the cleaning unit has entered for cleaning.

[0111] Regarding the control technology of the toilet device 30 described above, the relationship between the control technology and the issues related to the use of the toilet device 30 from the perspective of the cleaning unit will be explained.

[0112] Even if a malfunction occurs in the toilet unit 30, the cleaning unit aims to minimize the overflow of sewage. This problem can be solved by the aforementioned toilet malfunction detection and notification technology and the technology of stopping the cleaning and drainage function in the control technology of each toilet.

[0113] In the event of abnormalities such as blockages in the drain pipes, the cleaning unit wants to eliminate the abnormality as soon as possible. Such problems can be solved by the above-mentioned toilet abnormality detection and notification technology and the control technology of each toilet, including (7) re-cleaning technology and (8) automatic cleaning technology corresponding to the amount of toilet paper used.

[0114] Since the cleaning unit also needs to perform daily cleaning operations, it is desirable to reduce the amount of additional cleaning work required when an anomaly occurs. In addition, even if an anomaly does occur, it is desirable to be able to respond within the scheduled routine time period as much as possible. Furthermore, it is desirable to be able to respond without immediately rushing to the toilet where the anomaly has occurred. Such issues can be addressed through the aforementioned toilet anomaly detection and notification technology and the control technologies for each toilet, including (5) automatic door and window locking technology and (7) re-cleaning technology.

[0115] To reduce the situation where the cleaning unit rushes to the stall 24 to clean a toilet that has malfunctioned (30), but cannot clean because the user is already inside, the following issues can be addressed: (2) a notification technology indicating that the cleaning and drainage function has stopped; (3) a notification technology indicating that the malfunction detection has been completed; (5) an automatic door and window locking technology; and (9) a technology to confirm whether the user is in the toilet where the malfunction has occurred.

[0116] When the cleaning unit rushes to the stall 24 to clean the toilet unit 30 that has malfunctioned, it will not encounter the user inside the stall. This is also true from the user's perspective. This problem can be solved by the toilet malfunction detection and notification technology and the technology in each toilet control system, such as (9) technology that confirms whether the user is in the toilet where malfunction has occurred.

[0117] The control technology for each toilet device described above can be implemented in each toilet 21, or each toilet device 30 can implement the control technology for each toilet device described above on its own. In the former case, it is sufficient to install a management device 50 in the toilet 21. In the latter case, a management device 50 can be installed in the toilet device 30, or the function of the management device 50 can be implemented in the control device 34 of the toilet device 30.

[0118] Figure 7 This figure illustrates the configuration of the toilet device 30 according to the embodiment. The toilet device 30 shown in this figure, besides... Figure 6 In addition to the toilet device 30 shown, a water level sensor 80 is also included. Furthermore, the control device 34 of the toilet device 30 shown in this figure, besides... Figure 6 In addition to the control device 34, the toilet device 30 shown also includes an abnormality detection unit 84 and a notification unit 85.

[0119] The water level sensor 80 detects the amount of water inside the toilet bowl of the toilet device 30. As described above, the water level sensor 80 can be a non-contact water level sensor, such as an electrostatic capacitive type, installed on the outer surface of the toilet bowl or on the outer surface of the trap between the drain outlet and the drain pipe at the bottom of the toilet bowl. The sensor information acquisition unit 36 ​​acquires the water level detected by the water level sensor 80.

[0120] The anomaly detection unit 84 detects an anomaly in the water level when the detected water level exceeds a predetermined value. The anomaly detection unit 84 can also detect water level or other anomalies based on detection information from various sensors acquired by the sensor information acquisition unit 36, in addition to or in place of the water level detected by the water level sensor 80. For example, as described above, it can also detect water level or other anomalies based on detection information from a sound sensor or vibration sensor installed near the drain pipe.

[0121] When an anomaly is detected by the anomaly detection unit 84, the notification unit 85 notifies the management device 50, the management main terminal 40, the cleaning main terminal 42, the manufacturing main terminal 44, or the maintenance main terminal 46 of the occurrence of the anomaly.

[0122] The above-mentioned anomaly detection and notification can also be achieved through... Figure 7 The toilet device 30 shown is implemented. In this case, the function of the fault detection unit 62 is performed by the fault detection unit 84, and the function of the notification unit 63 is performed by the notification unit 85. Furthermore, the control of each of the aforementioned toilet devices can also be achieved through… Figure 7 The toilet device 30 shown is implemented. In this case, the function of the instruction decision unit 64 is performed by the control unit 37.

[0123] Figure 7 The toilet device 30 shown can achieve coordinated control of the aforementioned multiple toilet devices through communication with the management device 50 or other toilet devices 30. In this case, the function of the instruction decision unit 64 is also performed by the control unit 37.

[0124] [Toilet cleaning and management]

[0125] As another feature of the management device 50 in this embodiment, the technology for managing the timing or content of toilet cleaning will be explained. The cleaning instruction determination unit 67 determines the timing or content of toilet cleaning 21 based on the usage information of the toilet device 30. The cleaning instruction notification unit 68 notifies the entity responsible for cleaning toilet 21 of the timing or content determined by the cleaning instruction determination unit 67.

[0126] The cleaning instruction decision unit 67, referring to the usage information storage unit 73, determines when to clean the toilet 21, based on the principle that the cleaning frequency of toilets 21 equipped with frequently used toilet devices 30 is higher than that of toilets 21 equipped with less frequently used toilet devices 30. The usage frequency of the toilet devices 30 can also be calculated based on information detected by human body sensors stored in the usage information storage unit 73, the opening and closing status of the toilet door 23 and the stall door 25, and the usage status of the controller 31 or drain control lever. When the cleaning supervisor performs cleaning of the toilet 21 at the time indicated by the management device 50, information indicating the cleaning status is sent from the cleaning main terminal 42 to the management device 50. The usage information acquisition unit 61 stores the cleaning status information received from the cleaning main terminal 42 in the usage information storage unit 73. The cleaning instruction decision unit 67, referring to the usage information storage unit 73, acquires the cleaning frequency of the toilet 21.

[0127] The cleaning instruction decision unit 67 can also determine the content of cleaning the toilet 21 in a way that the number of cleaning items or the scope of the toilet 21 with the toilet device 30 that is used more frequently is more than that of the toilet 21 with the toilet device 30 that is used less frequently.

[0128] According to this technology, by increasing the frequency and content of cleaning the toilets 21 that are used more frequently, the toilets 21 that are prone to dirt can be kept clean, while the frequency of cleaning the toilets 21 that are used less frequently can be reduced, thus reducing the workload and burden on the person in charge of cleaning. In addition, the frequency and content of cleaning the toilets 21 can be changed automatically and dynamically, thus also reducing the burden on the person in charge of managing the toilets 21.

[0129] The present invention has been described above based on embodiments, but these embodiments merely illustrate the principles and applications of the invention. Furthermore, many modifications and configuration changes can be made in the embodiments without departing from the spirit of the invention as defined in the claims.

[0130] In this embodiment, an example of managing a toilet device installed in a facility has been described, but the technology of this embodiment can also be applied to managing toilets in ordinary residential buildings and public toilets installed in parks or roads.

[0131] When the invention embodied through the above embodiments and variations is generalized, the following technical ideas are derived.

[0132] A toilet management system according to one aspect of the present invention includes: a toilet device installed in a restroom; a management device for managing the usage status of the toilet device; and a communication device for sending usage status information associated with the usage status of the toilet device to the management device. The management device includes: an acquisition unit that acquires usage status information from the communication device; and an anomaly detection unit that detects an anomaly in the toilet device or equipment or machinery installed inside or around the restroom when the usage status information acquired by the acquisition unit meets predetermined conditions. According to this aspect, anomalies occurring in the restroom can be detected quickly, thus enabling proper maintenance and management of the restroom.

[0133] Usage status information can also be information indicating the usage status of the toilet device. The anomaly detection unit can also determine an anomaly when it receives information indicating that the water level inside the toilet bowl exceeds a predetermined value. The toilet device can also be equipped with a non-contact water level sensor installed on the outer surface of the toilet bowl, or on the outer surface of the trap between the drain outlet and the drain pipe at the bottom of the toilet bowl, for detecting the water level inside the toilet bowl. Based on this, anomalies such as sewage overflow that could cause significant impact can be quickly detected, and appropriate measures can be taken, thus minimizing the impact.

[0134] Usage information can also be information indicating the operational status of the controller, which is used by the user to input operating instructions into the toilet. The anomaly detection unit can also determine that an anomaly has occurred when it receives information indicating that the same button on the controller has been operated multiple times consecutively. Based on this, even anomalies that are difficult to detect through managerial inspections can be detected quickly.

[0135] Usage status information can also refer to the status of equipment or machines installed inside or around the bathroom. The anomaly detection unit can also determine an anomaly has occurred when it receives information indicating that the time from when the bathroom door is closed until it is reopened is less than a predetermined value. In this respect, the cost of sensors and other components required for anomaly detection can be reduced, and anomalies can be detected appropriately.

[0136] Usage information may also include: information indicating the usage status of the toilet device, information indicating the operational status of the controller used by the user to input operating instructions into the toilet device, and information indicating the status of equipment or machines installed inside or around the bathroom. The anomaly detection unit can also detect anomalies in the toilet device or equipment or machines installed inside or around the bathroom when any two or more combinations of this information meet predetermined conditions. The anomaly detection unit can also determine an anomaly has occurred when it receives information indicating that the bathroom door has been closed for a predetermined time and the toilet device installed in that bathroom has not been used for a predetermined time. Based on this aspect, by referring to multiple pieces of information, anomalies can be detected more accurately and quickly.

[0137] Another aspect of the present invention is a management device. This device includes: an acquisition unit that acquires usage status information related to the usage status of a toilet unit installed in the restroom; and an anomaly detection unit that detects an anomaly in the toilet unit or equipment or machinery installed inside or around the restroom when the usage status information acquired by the acquisition unit meets predetermined conditions. Because anomalies occurring in the restroom can be detected quickly, the restroom can be appropriately maintained and managed.

[0138] The present invention also includes the following aspect 1.
