Mode for Carrying Out the Invention

[0019] An embodiment of the toilet system according to the present invention will be described based on the drawings. As shown in FIG. 1, the toilet system 1 is provided in the toilet room 2, and a plurality of toilet booths 4 are provided inside the toilet room 2. Each of the plurality of toilet booths 4 is a private room partitioned by a concrete wall, a partition, or the like. A toilet room entrance / exit 3 for the user U to enter and exit is formed in the toilet room 2.

[0020] As shown in Figure 2, the toilet system 1 comprises a toilet booth 4, a motion sensor 5 capable of detecting the presence or absence of a user U inside the toilet booth 4, and an automatic sterilization means 6 for sterilizing the inside of the toilet booth 4. The motion sensor 5 is composed of an infrared sensor that detects a person entering the toilet booth 4, and can detect the presence of a person inside the toilet booth 4 (user U has entered the toilet booth 4) and the absence of a person inside the toilet booth 4 (user U has left the toilet booth 4). Thus, in addition to detecting when user U enters the toilet booth 4, the motion sensor 5 can also detect when user U leaves the toilet booth 4, and is provided as an exit sensor that detects when user U leaves the toilet booth 4.

[0021] As shown in Figures 7 and 8, the automatic sterilization means 6 is configured to perform an automatic sterilization operation in which, when the motion sensor 5 detects that user U has left the toilet booth 4, the door 7 of the toilet booth 4 is locked in the closed position to sterilize the inside of the toilet booth 4, and the lock on the door 7 is released after the sterilization of the inside of the toilet booth 4 is completed.

[0022] Furthermore, as shown in Figures 1 to 8 and Figure 13, the toilet system 1 includes an automatic flushing means 9 (see Figure 13) for flushing the toilet bowl 8 installed in the toilet booth 4, and a seating sensor 10 capable of detecting whether or not user U is seated on the toilet bowl 8. The seating sensor 10 is composed of a pressure sensor that detects the pressure acting on the toilet seat 20, and can detect when the pressure acting on the toilet seat 20 exceeds a set value (user U is seated on the toilet seat 20 (toilet bowl 8)) or when the pressure acting on the toilet seat 20 falls below a set value (user U has left the toilet seat 20 (toilet bowl 8)). Thus, in addition to detecting when user U is seated on the toilet bowl 8, the seating sensor 10 can also detect when user U has left the toilet bowl 8, and is provided as a seating sensor that detects when user U has left the toilet bowl 8.

[0023] As shown in Figures 5 and 6, the automatic flushing means 9 is configured to close the toilet lid 21 provided on the toilet bowl 8 when the seating sensor 10 detects that the user U has left the toilet bowl 8, and then perform an automatic flushing operation to flush the inside of the toilet bowl 8 with water while the toilet lid 21 is closed.

[0024] Next, we will provide an explanation of toilet booth 4 based on Figures 2 to 8, and also explain how user U uses toilet booth 4. As shown in Figures 1 to 8, the toilet booth 4 includes a door 7 that can be opened and closed between a closed position (a position in which the booth entrance 13 for user U to enter and exit is closed) and an open position (a position in which the booth entrance 13 is open), a door drive unit 14 for opening and closing the door 7, a locking device 15 that can be switched between a state in which the door 7 is locked in the closed position and a state in which it is unlocked, a locking device drive unit 16 (see Figure 13) for operating the locking device 15, and a toilet bowl 8.

[0025] As shown in Figures 2 to 8, the toilet bowl 8 comprises a toilet bowl 19, a toilet seat 20, and a toilet lid 21. Also, as shown in Figure 13, the toilet bowl 8 includes a toilet bowl drive unit 22 that swings the toilet seat 20 and toilet lid 21, a flushing device 23 that flushes the inside of the toilet bowl 19 (inside the toilet bowl 8), a toilet seat sterilization device 24 that sterilizes the toilet seat 20, and a seating sensor 10. The toilet seat 20 is configured to swing between a user position used by the user U and a retracted position (not shown) where it is swung upward from this user position. The toilet lid 21 is configured to swing between a closed toilet bowl 8 position (see Figures 2, 3, 6 to 8) and an open toilet bowl 8 position where it is swung upward from this position (see Figures 4 and 5). As shown in Figure 8, the toilet seat sterilization device 24 is installed on the inner surface of the toilet lid 21 (the surface facing downwards when the lid is closed) so that it can sterilize the inside of the toilet bowl 8, including the toilet seat 20, when the toilet seat 20 is in the usage position and the toilet lid 21 is closed.

[0026] Furthermore, as shown in Figures 2 to 8, the toilet booth 4 is equipped with a motion sensor 5, an outer door operating unit 26 for opening and closing the door 7 by operation from outside the toilet booth 4, an inner door operating unit 27 for opening and closing the door 7 by operation from inside the toilet booth 4, and a booth sterilization device 28 for sterilizing the inside of the toilet booth 4 from the ceiling. In addition, as shown in Figure 13, the toilet booth 4 is equipped with a booth transceiver unit 29 capable of transmitting information to a toilet room transceiver unit 31, which will be described later, and a booth control unit 30 that controls the door drive unit 14, the lock device drive unit 16, the toilet bowl drive unit 22, the flushing device 23, and the booth transceiver unit 29.

[0027] Figure 3 shows the state in which user U has opened the door 7 by operating the outer door operating unit 26. The booth control unit 30 detects operation of the outer door operating unit 26 and controls the door drive unit 14 to open the door 7 if the door 7 is not locked by the locking device 15, and to keep the door 7 in the closed position without driving the door drive unit 14 if the door 7 is locked by the locking device 15. The outer door operating unit 26 is made up of a non-contact sensor, and the user U can operate the outer door operating unit 26 without touching it. Therefore, if the door 7 is not locked in the closed position by the locking device 15, the user U can open the door 7 by bringing their hand close to the outer door operating unit 26. On the other hand, if the door 7 is locked in the closed position by the locking device 15, the user U cannot open the door 7 by bringing their hand close to the outer door operating unit 26.

[0028] Figure 4 shows the state in which the toilet lid 21 opens automatically as user U enters the toilet booth 4. Figure 4 also shows the state in which the door 7 closes and locks in the closed position when user U operates the inner door control unit 27 after entering the toilet booth 4. The booth control unit 30 controls the toilet drive unit 22 to open the toilet lid 21 when the motion sensor 5 detects that user U has entered the toilet booth 4. The booth control unit 30 also controls the door drive unit 14 and the locking device drive unit 16 to lock the closed door 7 with the locking device 15 when it detects operation of the inner door operation unit 27. The inner door operation unit 27 is made up of a non-contact sensor, so user U can operate the inner door operation unit 27 without touching it. Therefore, when user U enters the toilet booth 4, the toilet lid 21 can be opened automatically, and by bringing their hand close to the inner door operation unit 27, they can operate the open door 7 to the closed position and lock the closed door 7 with the locking device 15.

[0029] Figure 5 shows the state in which user U is seated on the toilet seat 20. Figure 6 shows the state in which the toilet lid 21 closes automatically as user U leaves the toilet seat 20, and the toilet bowl 8 is flushed. The booth control unit 30 performs an automatic flushing operation using the automatic flushing means 9 when the seating sensor 10 stops detecting that user U is seated on the toilet seat 20. In this automatic flushing operation, when the seating sensor 10 detects that user U has stood up from the toilet seat 20 and left the toilet bowl 8, it closes the toilet lid 21 provided on the toilet bowl 8 and flushes the inside of the toilet bowl 8 with water while the toilet lid 21 is closed. In other words, by standing up from the toilet seat 20 after sitting down, user U can have the inside of the toilet bowl 8 automatically flushed with the toilet lid 21 closed. As shown in Figure 13, the automatic flushing means 9 that performs the automatic flushing operation comprises a flushing device 23 that flushes the inside of the toilet bowl 8, a toilet drive unit 22 that closes the toilet lid 21, and a booth control unit 30 that controls the flushing device 23 and the toilet drive unit 22 in order to perform the automatic flushing operation based on the detection information from the seat sensor 10.

[0030] In this way, when user U leaves the toilet bowl 8 after using it, the automatic flushing mechanism 9 automatically closes the toilet lid 21 and flushes the inside of the toilet bowl 8, thus reliably preventing splashing caused by flushing with the toilet lid 21 open.

[0031] Figure 6 shows the state in which user U has opened the door 7 by operating the inner door control unit 27. Figure 7 also shows the state in which the door 7 is locked after it has automatically closed as user U exits the toilet booth 4. The booth control unit 30 detects operation of the inner door operating unit 27 and controls the door driving unit 14 and the locking device driving unit 16 so as to drive the door driving unit 14 to open the door 7 if the door 7 is not locked by the locking device 15, and drives the locking device driving unit 16 to release the lock by the locking device 15 before driving the door driving unit 14 to open the door 7 if the door 7 is locked by the locking device 15. Therefore, regardless of whether the door 7 is locked by the locking device 15 or not, the user U can open the door 7 from the closed position to the open position by bringing their hand close to the inner door operating unit 27.

[0032] Figure 8 shows the state in which the toilet booth 4 is being sterilized by the sterilization device S while the door 7 is locked in the closed position. The booth control unit 30 executes an automatic sterilization operation using the automatic sterilization means 6 when the motion sensor 5 switches from detecting a user U to no longer detecting one. In this automatic sterilization operation, the door drive unit 14 is driven to close the door 7, then the locking device drive unit 16 is driven to lock the closed door 7 with the locking device 15, and then the sterilization device S (booth sterilization device 28 and toilet seat sterilization device 24) is activated to start sterilizing the inside of the toilet booth 4. After a preset time has elapsed since the start of sterilization, the booth control unit 30 finishes sterilization by the sterilization device S, and then drives the locking device drive unit 16 to release the lock on the door 7 by the locking device 15. In other words, when user U leaves the toilet booth 4, the automatic sterilization means 6 automatically executes the automatic sterilization operation. As shown in Figure 13, the automatic sterilization means 6 that performs the automatic sterilization operation comprises a door drive unit 14 that closes the door 7, a locking device 15 that locks the door 7 in the closed position, a locking device drive unit 16 that operates the locking device 15, a sterilization device S that sterilizes the inside of the toilet booth 4, and a booth control unit 30 that controls the door drive unit 14, the locking device drive unit 16, and the sterilization device S based on detection information from the human motion sensor 5. In this embodiment, the booth sterilization device 28 and the toilet seat sterilization device 24 are composed of deep ultraviolet (UV-C) LEDs that emit deep ultraviolet light.

[0033] In this way, after user U uses toilet booth 4, the automatic sterilization means 6 can automatically sterilize the inside of toilet booth 4 while restricting other users U from entering toilet booth 4, so that the next user U can use the sterilized toilet booth 4.

[0034] As shown in Figures 9 and 11, the toilet system 1 is equipped with a booth-front display device 38 and a toilet room-front display device 45 that can display information about the toilet booth 4, and also has a function to transmit information about the toilet booth 4 to the user U's mobile terminal 49.

[0041] The booth control unit 30 controls the booth transceiver 29 to transmit usability information and sterilization information to the toilet room transceiver unit 31 based on the status of the locking device 15 and the status of the sterilization device S. The availability information indicates whether toilet booth 4 is available for use, and includes available information indicating that toilet booth 4 is available for use, and unavailable information indicating that toilet booth 4 is unavailable for use. The booth control unit 30 transmits availability information and unavailable information to the toilet room transceiver unit 31 from the time the user U operates the inner door operation unit 27 to lock the door 7 until the automatic sterilization operation is completed and the door 7 is unlocked. As mentioned above, the door 7 is temporarily unlocked when user U leaves toilet booth 4 between the time user U enters toilet booth 4 and locks the door 7 until the automatic sterilization operation is completed and the door 7 is unlocked, and unavailable information is transmitted during this time as well. Furthermore, the booth control unit 30 transmits available information as availability information from the time the automatic sterilization operation is completed and the door 7 is unlocked until the next user U operates the inner door operation unit 27 to lock the door 7. Furthermore, the sterilization information indicates whether the automatic sterilization operation is in progress or has been completed. This includes sterilization in progress information, indicating that the automatic sterilization operation is in progress, and sterilization completed information, indicating that the automatic sterilization operation has been completed. The booth control unit 30 transmits sterilization in progress information to the toilet room transceiver unit 31 as sterilization information from the start to the completion of the automatic sterilization operation, and transmits sterilization completed information as sterilization information from the completion of the automatic sterilization operation until the next automatic sterilization operation starts.

[0042] The toilet room transceiver unit 31 receives usability information and sterilization information transmitted from the booth transceiver unit 29, as well as cleaning information transmitted from the booth front transceiver unit 39. The toilet room control unit 34 stores the usability information, sterilization information, and cleaning information received by the toilet room transceiver unit 31 in the storage unit 32. Furthermore, the toilet room control unit 34 controls the toilet room transceiver 31 to transmit the availability information and sterilization information for one toilet booth 4 received by the toilet room transceiver 31 to the booth front transceiver 39 of the booth front display device 38 corresponding to the toilet booth 4 that transmitted the availability information and sterilization information.
