The smell in the restroom has first smell for which cleaning is needed and second smell for which cleaning is not needed. In a case where a smell value detected by the smell sensor is caused by the first smell, the control section performs notification of the cleaning guide. In a case where the smell value detected by the smell sensor is caused by the second smell, the notification section does not perform the notification of the cleaning guide.SELECTED DRAWING: Figure 5

Description

[Technical Field]

[0001] FIELD OF THE INVENTION Aspects of the present invention generally relate to cleaning guide systems and cleaning guide methods. [Background technology]

[0002] BACKGROUND ART There is known a management system that acquires the usage status of a toilet device from a sensor such as an odor sensor and determines the timing of cleaning a toilet room (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-166798 Summary of the Invention [Problem to be solved by the invention]

[0004] The management system disclosed in Patent Document 1 may erroneously report that cleaning is necessary even when the odor sensor detects an odor that does not require cleaning, for example.

[0005] The aspects of the present invention have been made based on the recognition of such problems, and have an object to provide a cleaning guide system and a cleaning guide method that can accurately guide cleaning of a restroom. [Means for solving the problem]

[0006] A first invention is a cleaning guide system comprising an odor sensor that detects odors in a restroom, a control unit that determines whether cleaning is necessary based on the detection results of the odor sensor, and an alarm unit that issues a cleaning guide notification when the control unit determines that cleaning is necessary, wherein the odors in the restroom include a first odor that requires cleaning and a second odor that does not require cleaning, and the control unit causes the alarm unit to issue a cleaning guide notification when the odor value detected by the odor sensor is due to the first odor, and does not cause the alarm unit to issue a cleaning guide notification when the odor value detected by the odor sensor is due to the second odor.

[0007] This cleaning guide system can prevent erroneous cleaning instructions from being issued when a second odor that does not require cleaning in the restroom is detected. This allows managers and cleaners to follow the appropriate cleaning instructions and quickly address accumulated or unexpected stains (such as feces, urine, or vomit around the toilet or on the floor, or abandoned diapers).

[0008] The second invention is a cleaning guide system according to the first invention, further comprising a human body detection unit that detects a human body in the restroom, and the second odor is an odor generated when the human body detection unit detects a human body.

[0009] This cleaning guide system can prevent cleaning guidance from being issued for the secondary odors that arise from defecation, urination, and flatulence by users in the restroom, which are temporary and do not require cleaning of the restroom.

[0010] The third invention is a cleaning guide system according to the first invention, further comprising a urinal installed in the restroom, wherein the second odor is an odor generated when an automatic flush is performed in which cleaning water is automatically supplied to the urinal.

[0011] When a urinal is automatically flushed, an odor may rise from the drain pipe. This odor is temporary due to the flush and is a secondary odor that does not require cleaning. This cleaning guide system can prevent cleaning guidance from being performed for this secondary odor that occurs during flushing.

[0012] The fourth invention is a cleaning guide system characterized in that, in the first invention, the odor sensor is capable of detecting the detergent odor of the detergent used for cleaning, and the second odor is the detergent odor.

[0013] After cleaning the restroom, an odor is generated from the detergent. This detergent odor is a second odor that does not require cleaning. This cleaning guide system can detect the detergent odor and prevent cleaning guidance from being given.

[0014] The fifth invention is a cleaning guide system characterized in that, in the fourth invention, the control unit causes the notification unit to notify that cleaning has been performed when the odor sensor detects the detergent odor.

[0015] According to this cleaning guide system, by detecting the odor of detergent and informing the user that cleaning is to be performed, it is possible to know whether the cleaning of the restroom is being performed appropriately.

[0016] A sixth invention is the cleaning guide system according to any one of the first to fifth inventions, characterized in that one odor sensor is provided in the restroom.

[0017] According to this cleaning guide system, it is possible to efficiently detect whether or not cleaning is required in a restroom using a single odor sensor.

[0018] A seventh invention is a cleaning guide method comprising an odor sensor that detects odors in a restroom, a control unit that determines whether cleaning is necessary based on the detection results of the odor sensor, and an alarm unit that issues a cleaning guide alert when the control unit determines that cleaning is necessary, wherein the control unit causes the alarm unit to issue a cleaning guide alert when the odor value detected by the odor sensor is due to a first odor that requires cleaning, and does not cause the alarm unit to issue a cleaning guide alert when the odor value detected by the odor sensor is due to a second odor that does not require cleaning.

[0019] This cleaning guide method can prevent erroneous cleaning guides from being issued when a second odor that does not require cleaning in the restroom is detected. This allows managers and cleaners to quickly respond to accumulated dirt and unexpected dirt (such as feces, urine, vomit, and abandoned diapers around the toilet or on the floor) by following the appropriate cleaning guide. [Effects of the Invention]

[0020] According to aspects of the present invention, a cleaning guide system and a cleaning guide method are provided that can accurately guide cleaning of a restroom. [Brief explanation of the drawings]

[0022] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals, and detailed descriptions thereof will be omitted where appropriate. FIG. 1 is an explanatory diagram showing a cleaning guide system according to an embodiment of the present invention. FIG. 2 is a block diagram showing a cleaning guide system including a toilet room, a management device, and a notification unit.

[0023] The cleaning guide system 1 provides guidance as to whether or not cleaning of a restroom 100 is necessary. The restroom 100 may be, for example, a general toilet, a multipurpose toilet, a toilet installed in a public facility or building, or a diaper changing room without a urinal or toilet. In this example, the restroom 100 is a men's toilet installed in a public facility or building.

[0024] As shown in Fig. 1, the restroom 100 has booths 10 to 12, each equipped with a toilet basin 10a to 12a. The restroom 100 is also equipped with a sink 20, a hand dryer (not shown), and other facilities. The restroom 100 is also equipped with urinals 23a to 23c.

[0025] The cleaning guide system 1 includes a management device 40 connected to the restroom 100 via a network 30 , and a notification unit 50 connected to the management device 40 via the network 30 .

[0026] The human body detection unit 15 detects a human body (user) in the restroom 100. In this example, a plurality of human body detection units 15 are provided in the restroom 100. Each human body detection unit 15 detects a user using the booths 10 to 12 and a user using the urinals 23a to 23c, respectively.

[0027] The human body detection unit 15 that detects users in the booths 10-12 is capable of detecting users entering and exiting the booths 10-12, for example, by using an entry / exit sensor such as a door sensor, a seating sensor that detects sitting on the toilet bowls 10a-12a, and an infrared sensor that detects users in the booths 10-12.

[0028] The human body detector 15 detects users who use the urinals 23a to 23c and is configured to detect users positioned in front of the urinals 23a to 23c using, for example, an infrared sensor or a radio wave sensor. The detection result by the human body detector 15 is transmitted to the management device 40 via the network device 25.

[0029] The odor sensor 17 detects odors in the restroom 100. Specifically, the odor sensor 17 detects sulfur components and alcohol components in the restroom 100. The odor sensor 17 detects and quantifies the sulfur reaction caused by putrid odors and the alcohol reaction caused by detergent odors. In this example, multiple odor sensors 17 are provided in the restroom 100.

[0030] An odor sensor 17 is provided in each of the booths 10-12 and each of the urinals 23a-23c. The odor sensor 17 provided in each of the booths 10-12 is located, for example, near the toilets 10a-12a and detects odors in the booths 10-12. The odor sensor 17 provided in each of the urinals 23a-23c is located, for example, above a drain through which urine and flushing water flow and detects odors in the urinals 23a-23c. The detection results by the odor sensor 17 are sent to the management device 40 via the network device 25.

[0031] The network device 25 is installed in the restroom 100. The network device 25 is a gateway that converts protocols. Note that the network device 25 is not limited to a gateway, and may be any communication device that can communicate with the outside.

[0032] The network device 25 transmits a plurality of pieces of device information related to the usage status and maintenance needs of devices such as the toilet bowls 10a-12a and urinals 23a-23c in the restroom 100 to the management device 40 via the network 30. The network device 25 transmits the detection results of the human body detection unit 15 and the odor sensor 17 to the management device 40 via the network 30. The network device 25 also receives various command signals transmitted from the management device 40 and transmits them to the devices in the restroom 100.

[0033] The network 30 is, for example, the Internet or a LAN (Local Area Network), and connects the network devices 25 and the notification unit 50 via a management device 40. The network 30 may connect the management device 40 and the notification unit 50, and the management device 40 and the network devices 25, via a wired or wireless connection, or may be a combination of a wired and wireless connection. The network 30 may be any network that enables communication between the network devices 25, the management device 40, and the notification unit 50.

[0034] The management device 40 is installed at a location away from the restroom 100. The management device 40 is, for example, a cloud server, and is connected to the notification unit 50 via the network 30 to manage information about the restroom 100. The management device 40 may be installed in the same building as the restroom 100.

[0035] The management device 40 manages, for example, a plurality of restrooms 100. The management device 40 has a first communication unit 42, a second communication unit 44, and a control unit 46. The management device 40 acquires information about the restrooms 100 and calculates whether or not the restrooms 100 need to be cleaned.

[0036] The first communication unit 42 receives a command signal transmitted from the network device 25 in the restroom 100. The first communication unit 42 also transmits a command signal to the network device 25. That is, the first communication unit 42 and the network device 25 communicate bidirectionally. The first communication unit 42 is controlled by the control unit 46.

[0037] The second communication unit 44 receives a command signal transmitted from the notification unit 50. The second communication unit 44 also transmits a command signal to the notification unit 50. That is, the second communication unit 44 and the notification unit 50 communicate bidirectionally. The second communication unit 44 is controlled by the control unit 46.

[0038] The control unit 46 controls the operation of the first communication unit 42 and the second communication unit 44. The control unit 46 stores, in the memory unit 47, for example, command signals transmitted from the network device 25 (such as the detection result of the human body detection unit 15, the detection result of the odor sensor 17, and device information in the restroom 100) and command signals transmitted from the alarm unit 50. The control unit 46 also causes the first communication unit 42 to transmit a command signal to the network device 25 and the second communication unit 44 to transmit a command signal to the alarm unit 50.

[0039] The control unit 46 acquires the odor in the restroom 100 detected by the odor sensor 17. In this example, the control unit 46 acquires the odor in each of the booths 10-12 and the odor around the urinals 23a-23c. The control unit 46 also acquires the presence or absence of a user from the human body detection unit 15. The control unit 46 is able to recognize the positions of the human body detection units 15 and odor sensors 17 from the unique identification numbers assigned to the multiple human body detection units 15 and multiple odor sensors 17.

[0040] The control unit 46 then associates the acquired information with the date and time and stores it in the memory unit 47. Furthermore, the control unit 46 calculates whether or not cleaning of the restroom 100 is necessary based on the information from the odor sensor 17 and the information from the human body detection unit 15. The control unit 46 determines that there is an odor if the odor value S detected by the odor sensor 17 is equal to or greater than the threshold value Sx. On the other hand, the control unit 46 determines that there is no odor if the odor value S detected by the odor sensor 17 is less than the threshold value Sx. The control unit 46 causes the second communication unit 44 to transmit information on whether or not cleaning of the restroom 100 is necessary to the notification unit 50.

[0041] The notification unit 50 is an administrator terminal, such as a mobile terminal 50a or a PC terminal 50b, owned by an administrator who manages the restroom 100. The notification unit 50 is connected to the management device 40 via the network 30.

[0042] For example, the manager can connect to the management device 40 to obtain (view) various pieces of equipment information about the toilet bowls 10a-12a installed in the restroom 100. The manager can also operate the notification unit 50 to cause the management device 40 to output various command signals to the restroom 100. Note that the mobile terminal 50a is only required to be capable of displaying various pieces of information about the restroom 100, and is not limited to being owned by the manager, but may also be owned by a cleaner. Furthermore, the mobile terminal 50a and the PC terminal 50b may be capable of communicating with each other.

[0043] In this way, the cleaning guide system 1 makes the restroom 100 an IoT (Internet of Things) device, allowing the manager to centrally manage information such as the usage status of the restroom 100, whether maintenance is required, and whether cleaning is required for the restroom 100. This allows the manager to grasp information about the restroom 100 from a location away from the restroom 100.

[0044] Next, the calculation for determining cleaning performed by the control unit 46 will be described with reference to FIGS. FIG. 3 is a flowchart showing cleaning determination control executed by the control unit of the management device. FIG. 4 is a flowchart showing cleaning determination control executed by the control unit of the management device. FIG. 5 is a time chart showing an example of the relationship between the passage of time and the odor value. FIG. 6 is an explanatory diagram showing an example of cleaning information displayed by the notification unit. FIG. 7 is an explanatory diagram showing an example of a history of cleaning information displayed on the notification unit.

[0045] The restroom 100 has a cleaning guide method using cleaning determination control as shown in Figs. 3 and 4. The control processing program shown in Figs. 3 and 4 is stored in advance in the memory unit 47 of the management device 40. The control unit 46 infers the reason for the acquired odor value and determines the need for cleaning of the restroom 100. The control processing program (cleaning guide method) shown in Figs. 3 and 4 is repeatedly executed at a predetermined interval. Note that in Figs. 3 and 4, each step is indicated by "S", and for example, "step 1" is indicated by "S1".

[0046] FIG. 3 shows a control process for determining whether the odor generated in the restroom 100 is a continuing odor. In S1, the odor value S is acquired. That is, the control unit 46 acquires the odor value S detected by the odor sensor 17 and stores it in the memory unit 47. In this example, the control unit 46 acquires the odor values ​​S in the booths 10-12 and the odor values ​​S of the urinals 23a-23c.

[0047] In S2, it is determined whether the odor value S is equal to or greater than the threshold value Sx (S≧Sx). That is, the control unit 46 determines whether an odor is occurring in the booths 10-12 and around the urinals 23a-23c. The threshold value Sx is pre-stored in the storage unit 47. The threshold value Sx is set to a value that makes a user feel uncomfortable when entering, for example, the restroom 100 or the booths 10-12.

[0048] If S2 returns "YES," meaning that the odor value S is equal to or greater than the threshold value Sx, the process proceeds to S3. On the other hand, if S2 returns "NO," meaning that the odor value S is less than the threshold value Sx, the process ends and odor monitoring continues.

[0049] In S3, it is determined whether or not a human body has been detected. The odors in the restroom 100 are divided into a first odor that requires cleaning and a second odor that does not require cleaning. The first odor is, for example, an unpleasant odor caused by accumulated dirt. In other words, the first odor is an odor that cannot be removed (deodorized) without cleaning. The second odor is, for example, an unpleasant odor that occurs temporarily when a user uses the toilets 10a-12a and urinals 23a-23c. In other words, the second odor is an odor that disappears over time even without cleaning.

[0050] Therefore, the control unit 46 determines whether the odor being generated is the first odor or the second odor based on the detection information from the human body detection unit 15. When the human body detection unit 15 located in the same position as the odor sensor 17 that is detecting the presence of an odor indicates that a human body has been detected, the control unit 46 determines that the odor value S from the odor sensor 17 is due to the excretion of a user. For example, even if the odor sensor 17 installed in booth 10 indicates that an odor is present, if the human body detection unit 15 installed in booth 10 detects a human body, the control unit 46 determines that the odor being generated in booth 10 is due to the excretion of a user.

[0051] If S3 returns "YES," i.e., if the human body detection unit 15 has not detected a human body, the process proceeds to S4. S4 is a step that applies to the urinals 23a-23c. Therefore, if the odor is generated in one of the booths 10-12, the process skips S4 and proceeds to S5. On the other hand, if S3 returns "NO," i.e., if the human body detection unit 15 has detected a human body, the process ends and odor monitoring continues.

[0052] In S4, it is determined whether a predetermined time ts has elapsed since automatic flushing. Automatic flushing is performed on urinals 23a-23c, and flushing water is automatically flushed every predetermined time (for example, every few hours) to protect the equipment (such as to prevent urinary stones from adhering to the drain pipe). When automatic flushing is performed on urinals 23a-23c, an odor temporarily rises from the drain outlets of the urinals 23a-23c. The control unit 46 determines whether the odor occurring around the urinals 23a-23c is a second odor caused by automatic flushing.

[0053] The control unit 46 can determine whether automatic flushing has been performed, for example, based on the operation of a solenoid valve (not shown) that opens when flushing water is flowing into the urinals 23a-23c. That is, when the human body detection unit 15 does not detect a human body, the control unit 46 measures a predetermined time ts from the operation of the solenoid valve. The predetermined time ts is set to about several tens of seconds (for example, 20 to 30 seconds) and is stored in advance in the memory unit 47.

[0054] If S4 returns "YES," that is, if it is determined that the predetermined time ts has passed since the automatic flushing was performed, the process proceeds to S5. On the other hand, if S5 returns "NO," that is, if it is determined that the predetermined time ts has not passed since the automatic flushing was performed, the process ends and odor monitoring continues. In other words, the control unit 46 determines that the odor acquired in S1 was temporarily caused by the automatic flushing of the urinals 23a-23c.

[0055] In S5, the notification unit 50 displays (notifies) that cleaning is necessary. That is, the control unit 46 determines that the odor acquired in S1 is the first odor that cannot be removed without cleaning, and causes the second communication unit 44 to send a cleaning necessary signal to the notification unit 50. This cleaning necessary signal contains information about the position at which the odor sensor 17 is installed that has detected the first odor.

[0056] When the notification unit 50 receives the cleaning required signal, it displays the locations in the restroom 100 that require cleaning. For example, as shown in FIG. 6, the notification unit 50 displays that the booth 10 and the urinal 23b require cleaning. The manager can know from the notification unit 50 whether cleaning is required. The control unit 46 may also transmit a message to the notification unit 50 indicating that cleaning is not required. The notification unit 50 may display, for example, "Cleaning not required."

[0057] FIG. 4 shows a control process for determining whether or not the odor generated in the restroom 100 is caused by a deodorant. In S11 and S12, the same control processes as in S1 and S2 in FIG. 3 are executed. In the next S13, it is determined whether a detergent odor has been detected. The detergent odor is a second odor that does not require cleaning. The odor sensor 17 can distinguish between a sulfur reaction caused by a putrid odor and an alcohol reaction caused by a detergent odor. The control unit 46 determines whether the odor value information transmitted from the restroom 100 includes a sulfur reaction or an alcohol reaction.

[0058] If S13 returns "YES," meaning that it is determined that a detergent odor has been detected, the process ends. On the other hand, if S13 returns "NO," meaning that it is determined that a detergent odor has not been detected, the process proceeds to S14. In S14, the same control process as S5 in FIG. 3 is executed. Note that the control process in FIG. 3 and the control process in FIG. 4 may be executed together. For example, S13 in FIG. 4 may be executed after S2 or S4 in FIG. 3.

[0059] Fig. 5 shows a characteristic line diagram illustrating an example of the transition of odor values. A characteristic line diagram 60 shown by a solid line in Fig. 5 shows the transition of a first odor generated from accumulated dirt in, for example, the restroom 100. A characteristic line 61 shown by a dotted line in Fig. 5 shows the transition of a second odor generated from detergent after cleaning the restroom 100. A characteristic line 62 shown by a two-dot chain line in Fig. 5 shows the transition of a second odor generated by automatic cleaning, user excretion, etc.

[0060] For example, both characteristic line 60 and characteristic line 62 represent an unpleasant odor containing sulfur components. In this case, the second odor represented by characteristic line 62 exceeds threshold Sx at time t1 and falls below threshold Sx at time t2. That is, the second odor represented by characteristic line 62 is an odor that temporarily exceeds threshold Sx due to a user's excretion or equipment protection. The control unit 46 determines that the odor based on characteristic line 62 does not require cleaning even if it exceeds threshold Sx.

[0061] On the other hand, the first odor according to characteristic line 60 gradually increases toward time t3 and exceeds threshold value Sx at time t3. The first odor is caused by dirt accumulated in restroom 100 or inappropriate use by users (for example, vomit on the floor), and is an odor that will not be eliminated unless cleaning is performed. When the odor according to characteristic line 60 exceeds threshold value Sx, control unit 46 determines that cleaning is necessary.

[0062] After that, when the restroom 100 is cleaned at time t4, the first odor represented by characteristic line 60 disappears and the second odor (detergent odor) represented by characteristic line 61 begins to appear. This detergent odor weakens over time. Even if the odor (detergent odor) based on characteristic line 61 is equal to or greater than threshold value Sx, control unit 46 determines that the odor does not require cleaning.

[0063] 7 shows an example of cleaning history information for the restroom 100 (men's restroom) displayed on the notification unit 50. The control unit 46 stores odor information, cleaning information, and the like for the restroom 100 transmitted from the restroom 100 in the memory unit 47 in association with the date and time. For example, if the information on the odor value S includes an alcohol reaction, the control unit 46 determines that cleaning was performed at that time.

[0064] The manager can check the status of the restroom 100 by checking the cleaning history displayed on the notification unit 50. As shown in FIG. 7, the manager can confirm that, for example, booth 10 and urinal 23b were notified at 9:00 that they needed cleaning, and that the cleaning was completed at 9:10. The manager can also confirm that, for example, booth 11 was notified at 9:30 that it needed cleaning, and that the cleaning was completed at 11:00. In this way, the manager can grasp the elapsed time from when it was determined that cleaning was necessary until the cleaning was completed. Therefore, the manager can manage the sanitary condition of the restroom 100.

[0065] According to the embodiment, the control unit 46 causes the notification unit 50 to issue a cleaning guide when the odor value S detected by the odor sensor 17 is due to the first odor, and does not cause the notification unit 50 to issue a cleaning guide when the odor value detected by the odor sensor 17 is due to the second odor. This prevents the cleaning guide from being erroneously issued even if an odor equal to or greater than the threshold value Sx is detected when the restroom 100 is not soiled. This allows the manager or cleaner to properly and quickly clean the restroom 100 by following the appropriate cleaning guide.

[0066] The second odor is an odor generated when the human body detector 15 detects a human body. This makes it possible to distinguish odors generated by excretory actions by users of the restroom 100 from odors that require cleaning. This reduces false alarms from the cleaning guide.

[0067] The second odor is the odor generated when automatic flushing is performed, in which flush water is automatically supplied to the urinals 23a to 23c. This makes it possible to distinguish the odor generated when flush water is supplied to protect the urinals 23a to 23c from the odor that requires cleaning. This reduces false alarms from the cleaning guide.

[0068] Additionally, odor sensor 17 is capable of detecting the detergent odor of the detergent used for cleaning. The second odor is the detergent odor. This makes it possible to distinguish the odor generated by the detergent after cleaning from the odor that indicates the need for cleaning. This reduces false alarms by the cleaning guide.

[0069] In the above-described embodiment, an example has been described in which the human body detector 15 is provided in each of the booths 10-12 and the urinals 23a-23c. However, the present invention is not limited to this example, and the human body detector 15 may detect a user who enters the restroom 100. In other words, the controller 46 may determine that an odor generated when a user is present in the restroom 100 is the second odor.

[0070] In the above-described embodiment, an example has been described in which an odor sensor 17 is provided in each of the booths 10-12 and urinals 23a-23c. However, the present invention is not limited to this configuration, and for example, one odor sensor 17 may be provided in the restroom 100. One odor sensor 17 may detect odors corresponding to multiple devices in the restroom 100. Furthermore, the odor sensor 17 is not limited to being installed around the toilet bowls 10a-12a and urinals 23a-23c, but may also be installed around places where stains are likely to occur, such as the sink 20 or a diaper changing table (not shown).

[0071] In the above-described embodiment, an example has been described in which the notification unit 50 displays information indicating that cleaning is required. However, the present invention is not limited to this example, and the notification unit 50 may display information indicating that cleaning of the restroom 100 is being performed when, for example, a detergent odor is detected.

[0072] In the above-described embodiment, the control unit 46 has been described as determining, as a second odor that does not require cleaning, an odor that occurs when the human body detection unit 15 detects a user. However, the present invention is not limited to this. For example, the control unit 46 may determine, as a second odor, an odor that occurs when the toilets 10a-12a and urinals 23a-23c are flushed or when the remote controls for the toilets 10a-12a are operated. In other words, the control unit 46 may indirectly detect a user in the restroom 100 by detecting that a device in the restroom 100 has been used.

[0073] In the above-described embodiment, an example has been described in which the control unit 46 of the management device 40 performs a calculation to determine whether cleaning of the restroom 100 is necessary.
