The association operation between the user tag 160 and the second wireless communication unit 62, and the connection operation between the portable information terminal 100 and the second wireless communication unit 62 performed by the user, will be described later.

[0049] The toilet device 20 is located on the upper part of the toilet bowl 10. The toilet device 20 can be installed integrally with the toilet bowl 10 or can be installed detachably with respect to the toilet bowl 10.

[0050] The toilet unit 20 includes a main body 22, a toilet seat 24, and a toilet lid 26. The main body 22 has a housing 23 and multiple functional parts disposed within the housing 23. The toilet seat 24 is a part for a user to sit on and has an opening that exposes the basin 12. The user can defecate into the basin 12 while sitting on the toilet seat 24. The toilet lid 26 is provided in the toilet unit 20 as needed and can be omitted. The toilet seat 24 and the toilet lid 26 are axially supported on the main body 22 in a manner that allows them to rotate relative to the main body 22. It should be noted that in the description of this application, each of "up," "down," "front," "back," "left," and "right" refers to the direction of view from the user sitting on the toilet seat 24 with the toilet lid 26 open behind them.

[0051] The remote control 28 has, for example, multiple switches or sensors, and receives operation instructions from the user. Furthermore, the remote control 28 is connected to the main unit 22 via wired or wireless means, and transmits the operation instructions input by the user to the main unit 22. The main unit 22 (functional unit) executes the prescribed actions according to the operation instructions input from the remote control 28. It should be noted that the input of operation instructions to the main unit 22 can be performed, for example, via an operation panel provided on the main unit 22. Moreover, in this embodiment, the functional units of the toilet appliance 20 can be operated via the portable information terminal 100; therefore, the remote control 28 can be provided as needed.

[0052] The nozzle 30 is disposed within the housing 23. The nozzle 30 moves back and forth between a position retracted within the housing 23 and a position protruding forward from the housing 23 and entering the basin 12. It should be noted that... Figure 2 This indicates that the nozzle 30 has entered the basin 12.

[0053] The toilet unit 20 has a hygienic washing function section. When the nozzle 30 is inserted into the basin 12, the hygienic washing function section washes the user's area by spraying clean water from the nozzle 30 onto the user's buttocks or other areas.

[0054] For example, the portable information terminal 100 can be a smartphone or tablet computer owned by the administrator or user. However, the portable information terminal 100 is not limited to this and can be any portable terminal owned by the administrator or user.

[0055] The portable information terminal 100 is equipped with a program 200 (application software) for remotely operating the functional units of the toilet unit 20. Based on this program 200, the portable information terminal 100 executes a remote operation mode for the functional units.

The seating detection sensor 53 uses, for example, a mechanical switch or an electrostatic sensor. The seating detection sensor 53 is connected to the control unit 40. The seating detection sensor 53 outputs the human body detection result to the control unit 40.

[0062] The first wireless communication unit 61 performs wireless communication with the remote control 28. For example, the first wireless communication unit 61 is an infrared light receiving device that receives infrared signals transmitted from the remote control 28. The first wireless communication unit 61 is connected to the control unit 40. The first wireless communication unit 61 outputs command signals transmitted from the remote control 28 to the control unit 40. It should be noted that the remote control 28 and the first wireless communication unit 61 can communicate wirelessly via radio wave signals. Furthermore, if the remote control 28 is not installed in the toilet TR, the first wireless communication unit 61 may not be required.

[0063] The second wireless communication unit 62 performs wireless communication with the portable information terminal 100. For example, the second wireless communication unit 62 performs bidirectional wireless communication with the portable information terminal 100. The second wireless communication unit 62 uses a wireless communication device that conforms to communication standards, such as Bluetooth, ZigBee, Thread, or WiFi. Hereinafter, the case of using BLE (Bluetooth Low Energy) for wireless communication between the second wireless communication unit 62 and the portable information terminal 100 will be described as an example. It should be noted that the wireless communication between the second wireless communication unit 62 and the portable information terminal 100 can use conventional Bluetooth (Bluetooth Classic).

[0064] The second wireless communication unit 62 is connected to the control unit 40. The second wireless communication unit 62 outputs command signals sent from the portable information terminal 100 to the control unit 40, and sends the command signals to the portable information terminal 100 based on the instructions of the control unit 40. It should be noted that the first wireless communication unit 61 and the second wireless communication unit 62 can be configured as independent units, or as an integrated unit, such as a structure in which the first wireless communication unit 61 and the second wireless communication unit 62 are mounted on the same substrate or within the same unit.

[0065] The second wireless communication unit 62 constitutes the wireless communication unit of the present invention. The second wireless communication unit 62 outputs inherent first identification information and modifiable second identification information. The first identification information is individually set in each second wireless communication unit 62 and cannot be changed (overwritten). The first identification information is pre-stored in the storage unit 42. It should be noted that the first identification information can be stored in other storage units. Furthermore, the first identification information is pre-stored in the setting tag 150. The first identification information is used to wirelessly connect the administrator's portable information terminal 100 to the second wireless communication unit 62 when the administrator performs initial setup (setting) of the remote operation mode. That is, the first identification information is the setting ID used by the administrator.

[0066] The second identification information is modifiable (overwriteable) identification information. The second identification information is initially set and stored in storage unit 42 by the administrator. It should be noted that the second identification information can be pre-stored in storage unit 42. Furthermore, the second identification information can be stored in other storage units. The second identification information is pre-stored in the user tag 160. The second identification information is used by the user entering the toilet TR to wirelessly connect the toilet device 20 to their portable information terminal 100. That is, the second identification information is the user's user ID. Control unit 40 compares the identification information sent from portable information terminal 100 with the first and second identification information stored in storage unit 42, and determines whether a wireless connection exists. The initial setting performed by the administrator and the wireless connection operation performed by the user will be described later.

[0067] The toilet lid opening and closing device 70 is connected to the control unit 40 and automatically opens and closes the toilet lid 26 based on the control of the control unit 40.

[0069] A toilet seat heater 72 is located inside the toilet seat 24 and heats the seat surface of the toilet seat 24 from the inside. The toilet seat heater 72 is connected to the control unit 40 and heats the seat surface of the toilet seat 24 based on the control of the control unit 40. For example, the control unit 40 controls the drive of the toilet seat heater 72 so that the temperature of the seat surface of the toilet seat 24 reaches the temperature set by the operation of the remote control 28 or the portable information terminal 100.

[0070] A solenoid valve 73 is located between the water supply source and the nozzle 30. Opening the solenoid valve 73 supplies cleaning water to the nozzle 30. Closing the solenoid valve 73 stops the supply of cleaning water to the nozzle 30. The solenoid valve 73 is connected to a control unit 40. Based on the control of the control unit 40, the solenoid valve 73 switches the supply of cleaning water to the nozzle 30 and stops the supply of cleaning water to the nozzle 30. For example, the control unit 40 controls the opening and closing of the solenoid valve 73 according to the operation of the remote control 28 or the portable information terminal 100.

[0071] A warm water heater 74 is located downstream of the solenoid valve 73. The warm water heater 74 is connected to the control unit 40. Based on the control of the control unit 40, the warm water heater 74 heats the washing water supplied by the water source, for example, raising its temperature to a predetermined temperature. The warm water heater 74 converts the washing water supplied by the water source into warm water at the set temperature. For example, the warm water heater 74 can be an instantaneous heating (instantaneous) heat exchanger using a ceramic heater, or a hot water storage heating heat exchanger using a hot water storage tank.

[0072] Furthermore, for example, the control unit 40 can set the warm water temperature based on the operation of the remote control 28 or the portable information terminal 100. The user can set the warm water temperature to the desired temperature by operating the remote control 28 or the portable information terminal 100.

[0073] The nozzle drive device 75 moves the nozzle 30 forward and backward to a position where it is housed within the main body 22, and to a position where it protrudes forward from the main body 22 and enters the basin 12. The nozzle drive device 75 is connected to the control unit 40. The nozzle drive device 75 moves the nozzle 30 forward and backward based on the control of the control unit 40.

[0074] For example, the control unit 40 is configured to allow adjustment of the position of the nozzle 30 when it is inside the basin 12 via operation of the remote control 28 or the portable information terminal 100. With the nozzle 30 inside the basin 12, the user can adjust the position of the nozzle 30 in the forward / backward direction, etc., to the desired position by operating the remote control 28 or the portable information terminal 100. The nozzle 30, the solenoid valve 73, and the nozzle drive device 75 constitute a hygienic cleaning function unit for cleaning the user's local area.

[0075] The deodorizing device 76 draws in air from the basin 12 of the toilet 10, reduces the odor components in the air, and then discharges it to the outside of the main body 22, thereby deodorizing the air inside the basin 12. The deodorizing device 76 is connected to the control unit 40 and deodorizes the air inside the basin 12 based on the control of the control unit 40. For example, when the seating detection sensor 53 detects that the user has left the toilet seat 24, the control unit 40 activates the deodorizing device 76 for a predetermined time. Furthermore, for example, the control unit 40 activates the deodorizing device 76 based on the operation of the remote control 28 or the portable information terminal 100.

[0076] The indoor heating unit 77 heats the toilet TR by blowing warm air to the outside of the main body 22. The indoor heating unit 77 is connected to the control unit 40 and heats the toilet TR based on the control of the control unit 40.

The user can set the desired temperature in the toilet TR by operating the remote control 28 or the portable information terminal 100.

[0077] The lighting device 78 illuminates the basin 12 of the toilet bowl 10. The lighting device 78 is connected to the control unit 40 and illuminates the basin 12 based on the control of the control unit 40. For example, the control unit 40 activates the lighting device 78 by detecting a person using the human body detection sensor 51, making the basin 12 easily visible at night. Furthermore, the user can turn the lighting device 78 on and off using the remote control 28 or the portable information terminal 100.

[0078] The toilet washing device 79 supplies washing water to the toilet 10, thereby washing the toilet 10. For example, the toilet washing device 79 is provided in the water tank or water supply pipe of the toilet 10, and can automatically wash the toilet 10. The toilet washing device 79 is connected to the control unit 40 and performs toilet washing based on the control of the control unit 40. For example, the control unit 40 activates the toilet washing device 79 to wash the toilet 10 when it detects that the user has left the toilet seat 24 through the human body detection sensor 51 or the sitting detection sensor 53. In addition, the user can activate the toilet washing device 79 by operating the remote control 28 or the portable information terminal 100.

[0079] The warm air blower 80 blows warm air to a specific area of ​​the user's body. For example, the warm air blower 80 dries the user's area by blowing warm air onto it that has become wet from spot cleaning. The warm air blower 80 is connected to the control unit 40. Based on the control of the control unit 40, the warm air blower 80 switches between blowing warm air to the user's specific area and stops blowing warm air. The user can operate the warm air blower 80 by operating the remote control 28 or the portable information terminal 100.

[0080] Thus, the toilet unit 20 includes functional components such as a toilet seat opening and closing device 70, a toilet seat opening and closing device 71, a toilet seat heater 72, a solenoid valve 73, a warm water heater 74, a nozzle drive device 75, a deodorizing device 76, an indoor heating device 77, a lighting device 78, a toilet washing device 79, and a warm air blower 80. It should be noted that the functional components are not limited to the above, but can be any functional component that performs prescribed operations related to the use of the toilet unit 20.

The wireless communication unit 114 outputs command signals sent from the second wireless communication unit 62 of the toilet unit 20 to the control unit 110. Furthermore, the wireless communication unit 114 transmits command signals output from the control unit 110 to the second wireless communication unit 62 of the toilet unit 20.

[0086] The operation unit 116 receives operation instructions from users, etc. The operation unit 116 uses, for example, a touch panel. The operation unit 116 can be, for example, a mechanical switch or other sensors, or a combination of these. The operation unit 116 is connected to the control unit 110. The operation unit 116 outputs the input operation instructions to the control unit 110. For example, the control unit 110 controls the operation of various units such as the wireless communication unit 114 in response to the operation instructions input from the operation unit 116.

[0087] Display unit 118 displays various operation screens, etc. Display unit 118 uses a display device such as a liquid crystal display or an organic EL display. Display unit 118 is connected to control unit 110 and performs various displays based on the control of control unit 110. For example, if operation unit 116 is a touch panel, operation unit 116 is stacked on top of display unit 118.

[0088] The speaker 120 outputs various sounds. The speaker 120 is connected to the control unit 110 and outputs various sounds based on the control of the control unit 110.

[0089] Microphone 122 converts the input sound into an electrical signal. Microphone 122 is connected to control unit 110 and outputs the converted electrical signal to control unit 110. It should be noted that the operation of the toilet device 20 on the portable information terminal 100 can be operated by the sound information acquired through microphone 122.

[0090] The acquisition unit 124 acquires the upper portion of the setting tag 150 and the usage tag 160. For example, if the setting tag 150 and the usage tag 160 are OR codes (registered trademarks), the acquisition unit 124 is a camera device (camera). Furthermore, for example, if the setting tag 150 and the usage tag 160 are NFC tags, the acquisition unit 124 is a reader. The acquisition unit 124 outputs the acquired information to the control unit 110.

[0091] The storage unit 112 stores a program 200 for remotely operating the functional units of the toilet device 20 via the portable information terminal 100. In other words, the portable information terminal 100 is equipped with the program 200 (application) for remote operation.

[0092] For example, by instructing the operation unit 116 to start the program 200, the control unit 110 reads the program 200 from the storage unit 112. Furthermore, the control unit 110 performs remote operation mode actions based on the program 200, thereby enabling remote operation of the functional parts of the toilet device 20.

[0093] Next, refer to Figures 5 to 8 This section explains the initial setup procedures performed by the manager.

[0094] Figure 5 This is an explanatory diagram showing the initial setup for establishing a communication connection between the toilet unit and a portable information terminal.

[0095] Figure 6 This is an illustration of how to associate a user ID with a toilet fixture.

[0096] Figure 7 This is an explanatory diagram illustrating the settings for the operation buttons displayed on a portable information terminal.

[0097] Figure 8 This diagram illustrates the trial run after initial setup.

[0098] First, the administrator prepares to use tag 160 and enter toilet TR. Then, the administrator starts the remote operation program 200 (application) stored in storage unit 112. Afterwards, as... Figure 5 As shown, the setting tag 150 is read within the application via the acquisition unit 124. Alternatively, as... Figure 5 As shown, the setting tag 150 is read by the acquisition unit 124. This initiates the remote operation program 200 (application) stored in the storage unit 112. It should be noted that if the portable information terminal 100 does not have an application installed, when the setting tag 150 is read by the portable information terminal 100, the application acquisition (download) step can be accessed via the Internet.

[0099] The application program 200 has a control process that causes the wireless communication unit 114 to automatically send first identification information when the setting tag 150 is acquired. Therefore, the portable information terminal 100 sends the first identification information stored in the setting tag 150 when the setting tag 150 is acquired.

[0100] The control unit 40 of the toilet device 20 compares the first identification information sent from the portable information terminal 100 with the first identification information stored in the storage unit 42. If the two identification information matches, a wireless connection is established between the administrator's portable information terminal 100 and the second wireless communication unit 62. It should be noted that the determination of the wireless connection establishment can be performed by a dedicated control unit for controlling the second wireless communication unit 62.

[0101] And, as Figure 5 As shown, when a wireless connection is established with the second wireless communication unit 62, the portable information terminal 100 displays a setting screen (initial setting screen) on the display unit 118. That is, the program 200 installed on the portable information terminal 100 performs the initial setting step, that is, when the setting tag 150 storing the inherent first identification information of the second wireless communication unit 62 is read, the initial setting step of the toilet device 20 is performed.

[0102] It should be noted that, under this wireless connection, the functional units of the toilet device 20 cannot be operated via the portable information terminal 100. Therefore, for example, even if the user uses their own portable information terminal 100 to read the setting tag 150 and wirelessly connect to the second wireless communication unit 62, the functional units of the toilet device 20 cannot be operated.

[0103] like Figure 5 As shown, the settings screen displays buttons such as combination setting button 116a, display setting button 116b, trial run button 116c, and end button 116d. Combination setting button 116a is used to combine the user tag 160 (second identification information) with the second wireless communication unit 62 to enable remote operation mode. Display setting button 116b is used to set the type (style) of the operation buttons displayed on the user's portable information terminal 100. Trial run button 116c is used by the administrator to test the remote operation mode after the initial settings are completed.

[0104] First, the administrator operates the combination setting button 116a. Thus, as... Figure 6 As shown, the display unit 118 of the portable information terminal 100 displays a screen showing the reading of the usage tag 160. Furthermore, the administrator reads the usage tag 160 from the acquisition unit 124.

[0105] The storage unit 112 of the portable information terminal 100 stores a program 200 that, upon acquiring the usage tag 160, causes the wireless communication unit 114 to automatically send a write signal for second identification information. Therefore, when the portable information terminal 100 acquires the usage tag 160, it sends the second identification information stored in the usage tag 160. That is, the program 200 installed in the portable information terminal 100 executes a combination step, namely, when the usage tag 160 storing the modifiable second identification information of the second wireless communication unit 62 is read in the initial setting step, a write signal for the second identification information is sent. It should be noted that the write signal for the second identification information is not limited to automatic transmission; it can also be sent based on the administrator's operation.

[0106] The control unit 40 of the toilet device 20 causes the storage unit 42 to store the received second identification information. It should be noted that if the storage unit 42 stores different second identification information, it is rewritten (overwritten) with new second identification information. This forms a combination (association) between the tag 160 and the second wireless communication unit 62.

[0107] If the control unit 40 causes the storage unit 42 to store the second identification information, it causes the second wireless communication unit 62 to send a combination completion signal. If the control unit 110 of the portable information terminal 100 receives the combination completion signal, it then... Figure 6 As shown, the display unit 118 displays a message such as "Toilet installation and user ID combination setting completed." Furthermore, by pressing the confirmation button 116e, the control unit 110 of the portable information terminal 100 returns the display unit 118 to [the previous state]. Figure 5 The settings screen.

[0108] If the second wireless communication unit 62 stores second identification information, it sets both the first identification information and the second identification information as its own identification information. Furthermore, the second wireless communication unit 62 continuously outputs the first identification information and the second identification information stored in the storage unit 42.

[0109] Next, the administrator operates the display setting button 116b. Thus, as... Figure 7 As shown, the display unit 118 of the portable information terminal 100 displays a screen for setting the display of operation buttons used to operate the functions of the toilet unit 20. In this example, the display of the flush button 116g is set (see reference). Figure 8For example, if the toilet unit 20 has an automatic flushing function, that is, it has the function of automatically flushing clean water when the human body detection sensor 51 or the seating detection sensor 53 changes from a human body detection state to a non-detection state, the display of the flush button 116g can be set to "none". It should be noted that the presence or absence of the display setting for the operation button is not limited to the flush button 116g, and can also be other operation buttons.

[0110] After the administrator completes the display settings, they press the send button 116f. This causes the control unit 110 of the portable information terminal 100 to send a display setting signal to the wireless communication unit 114. If the control unit 40 of the toilet device 20 receives the setting signal, it causes the storage unit 42 to store the setting content and causes the second wireless communication unit 62 to send a setting completion signal.

[0111] If the control unit 110 of the portable information terminal 100 receives a setting completion signal, it causes the display unit 118 to display "Setting complete". Furthermore, by operating the confirmation button 116e, the control unit 110 of the portable information terminal 100 returns the display unit 118 to [the previous state]. Figure 5 The settings screen.

[0112] Next, the administrator operates the trial run button 116c. Thus, as... Figure 8 As shown, the display unit 118 of the portable information terminal 100 displays a screen for reading and using the tag 160. It should be noted that in the settings screen, if the end button 116d is pressed without performing a trial run, as... Figure 8 As shown, the display unit 118 can display a screen prompting a trial run.

[0113] Furthermore, the administrator reads the usage tag 160 through the acquisition unit 124. The storage unit 112 of the portable information terminal 100 stores a program 200 for automatically sending second identification information by the wireless communication unit 114 when the usage tag 160 is acquired. Therefore, when the portable information terminal 100 acquires the usage tag 160, it sends a connection request signal containing the second identification information stored in the usage tag 160.

[0114] The control unit 40 of the toilet device 20 compares the second identification information in the connection request signal sent from the portable information terminal 100 with the second identification information stored in the storage unit 42. If the two identification information matches, the control unit 40 executes a wireless connection step to establish a wireless connection between the portable information terminal 100 and the second wireless communication unit 62.

[0115] It should be noted that, in addition to comparing the second identification information, the control unit 40 can also compare the first identification information to determine whether a wireless connection has been established. Specifically, for example, it compares the second identification information in the connection request signal sent from the portable information terminal 100 with the second identification information stored in the storage unit 42. If the two identification information matches, the portable information terminal 100 communicates with the control unit 40. At this time, the control unit 40 sends the first identification information to the portable information terminal 100. The portable information terminal 100 sends the first identification information received from the control unit 40 to the control unit 40. The control unit 40 determines whether the first identification information received from the portable information terminal 100 matches the first identification information stored in the storage unit 42. Furthermore, if the first identification information matches, the control unit 40 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62. In this case, the comparison of the first identification information can be performed by the portable information terminal 100.

[0116] Once a wireless connection is established, the control unit 40 causes the second wireless communication unit 62 to send a connection permission signal. The connection permission signal contains information related to display settings stored in the storage unit 42. For example... Figure 8 As shown, if the control unit 110 of the portable information terminal 100 receives a connection permission signal, it causes the display unit 118 to display a screen (operation screen) of operation buttons based on information related to display settings. The connection request signal can be sent from the second wireless communication unit 62 of the toilet device 20. In this case, for example, when a connection request signal is sent from the toilet device 20, and the portable information terminal 100 obtains the usage tag 160, it compares the second identification information obtained by the portable information terminal 100 with the second identification information stored in the storage unit 42.

[0117] In this example, the display unit 118 displays, in addition to the flush button 116g, a posterior wash button 116h, a feminine wash button 116i, and an onomatopoeia generation button 116j. It should be noted that in the above display settings, when the flush button 116g is set to "none," the "none" signal for the flush button 116g is included in the connection permission signal. In this case, the display unit 118 does not display the flush button 116g.

[0118] Furthermore, the administrator operates, for example, the posterior washing button 116h. The control unit 110 of the portable information terminal 100 sends a posterior washing instruction signal to the second wireless communication unit 62. If the control unit 40 of the toilet device 20 receives the posterior washing instruction signal, it activates the nozzle drive device 75, causing the nozzle 30 to enter the basin 12.

[0119] Thus, the administrator can confirm that the user tag 160 and the second wireless communication unit 62 are properly integrated. The administrator disconnects the wireless connection with the second wireless communication unit 62 by operating the cut-off button 116k. Finally, the administrator installs the user tag 160 on the wall or other surface of the toilet TR, thereby completing the initial setup. It should be noted that the initial setup can be performed by the installer or maintenance personnel, not the administrator.

[0120] Next, we will explain the scenario where a user activates the functional parts of the toilet device 20 using their own portable information terminal 100.

[0121] Figure 9 This diagram illustrates how users operate toilet facilities using portable information terminals.

[0122] First, the user entering the toilet TR activates the remote operation program 200 (application) stored in the storage unit 112. Then, as... Figure 9 As shown, tag 160 is read and used within the application via acquisition unit 124. Alternatively, as... Figure 9 As shown, a user entering the toilet TR reads the usage tag 160 via the acquisition unit 124. This activates the remote operation program 200 (application) stored in the storage unit 112. It should be noted that if the application is not installed on the user's portable information terminal 100, the application acquisition (download) step can be accessed via the Internet when reading the usage tag 160 via the portable information terminal 100.

[0123] The application program 200 has a control process that, upon acquiring the user tag 160, causes the wireless communication unit 114 to automatically send second identification information and its own machine identification information. Therefore, when the portable information terminal 100 acquires the user tag 160, it sends a connection request signal containing the second identification information stored in the user tag 160. That is, the program 200 installed on the portable information terminal 100 executes a connection request step, specifically, when reading the user tag 160, it sends a connection request signal containing the second identification information to request a wireless connection.

[0124] The control unit 40 of the toilet device 20 compares the second identification information in the connection request signal sent from the portable information terminal 100 with the second identification information stored in the storage unit 42. If the two identification information matches, the control unit 40 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62.

[0125] It should be noted that, in addition to comparing the second identification information, the control unit 40 can also compare the first identification information to determine whether a wireless connection has been established. Specifically, for example, it compares the second identification information in the connection request signal sent from the portable information terminal 100 with the second identification information stored in the storage unit 42. If the two identification information matches, the control unit 40 communicates with the portable information terminal 100. At this time, the control unit 40 sends the first identification information to the portable information terminal 100. The portable information terminal 100 sends the first identification information received from the control unit 40 to the control unit 40. The control unit 40 determines whether the first identification information received from the portable information terminal 100 matches the first identification information stored in the storage unit 42. Furthermore, if the first identification information matches, the control unit 40 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62. In this case, the comparison of the first identification information can be performed by the portable information terminal 100.

[0126] Once a wireless connection is established, the control unit 40 causes the second wireless communication unit 62 to send a connection permission signal. The connection permission signal contains information related to display settings stored in the storage unit 42. For example... Figure 9 As shown, if the control unit 110 of the portable information terminal 100 receives a connection permission signal, it causes the display unit 118 to display the operation buttons based on information related to the display settings. That is, the program 200 installed on the portable information terminal 100 executes the usage steps, namely, when a connection permission signal sent from the second wireless communication unit 62 is received, the display unit 118 is made to display the operation buttons of the function section of the toilet device 20.

[0127] For example, when the flush button 116g is activated, the control unit 110 of the portable information terminal 100 sends a toilet cleaning command signal. Based on the toilet cleaning command signal, the control unit 40 activates the toilet cleaning device 79, thereby cleaning the toilet 10. In this way, the user can activate various functions of the bathroom device 20 through their portable information terminal 100 by operating various operation buttons displayed on the display unit 118.

[0128] When the user finishes using the toilet device 20, they operate the cut-off button 116k. This disconnects the wireless connection between the user's portable information terminal 100 and the second wireless communication unit 62 (wireless communication cut-off). In this case, if the wireless connection is cut off, the user can report (display) the communication cut-off to the portable information terminal 100.

[0129] It should be noted that the wireless connection between the portable information terminal 100 and the second wireless communication unit 62 can be terminated after a predetermined time has elapsed since the wireless connection was established. In this case, the predetermined time can be timed by the portable information terminal 100 or by the toilet device 20. Alternatively, the wireless connection can be terminated when the user is a predetermined distance from the toilet stall TR, using either the pedometer of the portable information terminal 100 or the radio wave strength between the portable information terminal 100 and the second wireless communication unit 62. This prevents the wireless connection between the portable information terminal 100 and the second wireless communication unit 62 from remaining continuous for extended periods. Therefore, in places such as public restrooms 1, multiple users can use their own portable information terminals 100 to utilize the toilet system 5.

[0130] Next, the control processing performed by the control unit 40 of the toilet device 20 on the setting mode and the portable information terminal usage mode will be explained.

[0131] Figure 10 This is a flowchart illustrating the control of the toilet unit's control over the setup mode and the portable information terminal usage mode. Figure 10 The control processing shown is pre-stored in the storage unit 42. Figure 10 The control process shown is executed repeatedly at a predetermined cycle after the power to the toilet unit 20 is turned on. Figure 10 In this context, "S" represents each step.

[0132] Figure 10 S1 to S3 in the control unit 40 will use the setting mode associated with the tag 160 and the second wireless communication unit 62. Figure 10 S4 and S5 are in the portable information terminal usage mode, that is, after the user's portable information terminal 100 is associated with the second wireless communication unit 62 using the tag 160, the user's portable information terminal 100 is wirelessly connected to the second wireless communication unit 62.

[0133] First, in S1, it is determined whether a write signal for the second identification information has been received. That is, after the portable information terminal 100 reads the setting tag 150, the control unit 40 reads the usage tag 160 and determines whether a write signal for the second identification information has been sent. If the result in S1 is "yes," meaning it is determined that a write signal for the second identification information has been received, the process proceeds to S2. On the other hand, if the result in S1 is "no," meaning it is determined that a write signal for the second identification information has not been received, the process proceeds to S4.

[0134] In S2, the second identification information is written. That is, the control unit 40 writes (overwrites) the received second identification information to the storage unit 42. Thus, the identification information of the second wireless communication unit 62 includes the second identification information in addition to the first identification information. In other words, the control unit 40 has a setting mode that stores the second identification information when a write signal for the second identification information is received.

[0135] In the next step S3, the first identification information and the second identification information are output. That is, the control unit 40 causes the second wireless communication unit 62 to output the first identification information and the second identification information. This concludes the setting of the second identification information in the setting mode of the second wireless communication unit 62.

[0136] S4 and S5 represent scenarios where the administrator is conducting a trial run or where a user is using their own portable information terminal 100. In the case of user operation, S1 is set to "No" and the process proceeds to S4. Conversely, in the case of administrator trial run, the process proceeds from S3 to S4.

[0137] In S4, it is determined whether the second identification information in the received connection request signal matches the second identification information stored in the storage unit 42. That is, the control unit 40 monitors the reception of the second identification information written to the storage unit 42 in S2. If the result in S4 is "yes," that is, if the control unit 40 determines that the second identification information in the received connection request signal matches the second identification information stored in the storage unit 42, then proceed to S5. On the other hand, if the result in S4 is "no," that is, if the control unit 40 determines that the second identification information in the received connection request signal does not match the second identification information stored in the storage unit 42, then the process ends. In other words, the control unit 40 has a portable information terminal usage mode that enables the second wireless communication unit 62 to wirelessly connect to the portable information terminal 100 when the stored second identification information is received.

[0138] In step S5, a connection permission signal is sent. That is, after establishing a wireless connection between the portable information terminal 100 and the second wireless communication unit 62, the control unit 40 sends a connection permission signal to the portable information terminal 100 and then terminates the connection. Upon receiving the connection permission signal, the portable information terminal 100 displays an operation screen on the display unit 118. Afterward, based on the command signal sent from the connected portable information terminal 100, the control unit 40 activates the functional units of the toilet device 20.

[0139] The toilet system 5 of this embodiment includes: a toilet device 20 having a second wireless communication unit 62 that can communicate with a portable information terminal 100, and a control unit 40 for controlling the second wireless communication unit 62; a setting tag 150 that stores inherent first identification information of the second wireless communication unit 62 and can be read by the portable information terminal 100; and a usage tag 160 that stores changeable second identification information of the second wireless communication unit 62 and can be read by the portable information terminal 100. Furthermore, when the control unit 40 wirelessly connects the second wireless communication unit 62 to the portable information terminal 100 based on the first identification information, it stores the second identification information when it receives the second identification information sent from the portable information terminal 100.

[0140] The first identification information of the second wireless communication unit 62 is inherent (unchangeable) information. Therefore, for example, if the user's portable information terminal 100 is wirelessly connected to the second wireless communication unit 62 solely through the setting tag 150, and the setting tag 150 is damaged or lost, a corresponding setting tag 150 must be prepared. That is, the portable information terminal 100 cannot be used to operate the functional parts of the toilet device 20 until the setting tag 150 is prepared. As a result, proper management of the second wireless communication unit 62 and the setting tag 150 is necessary. Furthermore, preparing a new setting tag 150 may be time-consuming. Therefore, the ease of use of the toilet system 5 may decrease.

[0141] Therefore, in the second wireless communication unit 62 of this embodiment, the toilet system 5 uses modifiable (overwriteable) second identification information in addition to the first identification information. The toilet system 5 uses a setting tag 150 storing the first identification information for administrators and a usage tag 160 storing the second identification information for users. That is, the usage tag 160 is a highly versatile tag that can be used with multiple second wireless communication units 62. Thus, for example, even if the usage tag 160 is damaged or lost, a new usage tag 160 can be used to access the toilet system 5.

[0142] Furthermore, in the second wireless communication unit 62 of this embodiment, the toilet system 5 uses modifiable (overwriteable) second identification information in addition to the first identification information. Therefore, even if the user tag is intentionally lost for prank purposes (e.g., someone other than the user uses the tag to establish a wireless connection, causing the toilet device to perform actions unrelated to the user's intentions), pranks can be suppressed because a new user tag 160 can use second identification information different from the original (before loss) second identification information.

[0143] Furthermore, upon receiving the stored second identification information, the control unit 40 wirelessly connects the second wireless communication unit 62 to the portable information terminal 100 that sent the second identification information. Thus, the toilet system 5 can use the changeable second identification information to wirelessly connect the second wireless communication unit 62 to the portable information terminal 100. Therefore, even if the currently used usage tag 160 becomes unusable, the toilet system 5 can be utilized as soon as possible by using a new usage tag 160.

[0144] In the above embodiment, the case where the control unit 40 of the toilet device 20 determines the establishment of a wireless connection between the toilet device 20 (second wireless communication unit 62) and the portable information terminal 100 is described as an example. However, as Figure 11 , Figure 12 As shown in the modified example, the determination of the establishment of a wireless connection between the toilet device 20 (second wireless communication unit 62) and the portable information terminal 100 can be made by the portable information terminal 100.

[0145] Figure 11 This is a flowchart illustrating the writing control of the second identification information performed by the control unit of the portable information terminal involved in the modified example.

[0146] Figure 12 This is a flowchart illustrating the control unit of the portable information terminal involved in the modified example performing connection establishment control using a tag.

[0147] Figure 11 , Figure 12 The control processing shown is pre-stored in the storage unit 112 of the portable information terminal 100. Figure 11 , Figure 12 The control process shown is executed repeatedly at a predetermined cycle. Figure 11 , Figure 12 In this context, "S" represents each step.

[0148] First, refer to Figure 11 The following explanation addresses the scenario where the administrator associates the tag 160 (second identification information) with the toilet device 20 (second wireless communication unit 62).

[0149] The administrator prepares to use tag 160 and enters toilet TR. The administrator then launches the remote operation program 200 (application) stored in storage unit 112. The remote operation program 200 (application) stored in storage unit 112 can be launched if the setting tag 150 can be read within the application via acquisition unit 124. It should be noted that if the application is not installed on the portable information terminal 100, the application acquisition (download) step can be accessed via the Internet when reading the setting tag 150 through the portable information terminal 100.

[0150] In S11, the first identification information is acquired. That is, the administrator reads the setting tag 150 containing the first identification information through the acquisition unit 124 of the portable information terminal 100. The control unit 110 of the portable information terminal 100 causes the storage unit 112 to store the acquired first identification information.

[0151] In the next step, S12, it is determined whether the first identification information sent from the second wireless communication unit 62 has been received. The second wireless communication unit 62 continuously outputs (sends) the first identification information from the moment the power to the toilet device 20 is turned on. Therefore, the portable information terminal 100 receives the first identification information as long as it enters the detection range of the second wireless communication unit 62.

[0152] Furthermore, if the condition in S12 is "yes," meaning it is determined that the first identification information has been received, then proceed to S13. On the other hand, if the condition in S12 is "no," meaning it is determined that the first identification information has not been received, then the process ends.

[0153] In the next step, S13, it is determined whether the acquired first identification information is consistent with the received first identification information. That is, the control unit 110 compares the first identification information stored in the storage unit 112 with the received first identification information.

[0154] Furthermore, if S13 is "Yes," meaning it is determined that the acquired first identification information matches the received first identification information, then proceed to S14. Conversely, if S13 is "No," meaning it is determined that the acquired first identification information does not match the received first identification information, then the process ends. Inconsistent first identification information can occur, for example, when first identification information is received from a second wireless communication unit 62 located in another toilet TR. It should be noted that in S12 and S13, for example, the portable information terminal 100 monitors the reception of the first identification information for a predetermined time starting from reading the setting tag 150.

[0155] In S14, a wireless connection is established between the portable information terminal 100 and the second wireless communication unit 62. That is, when the received first identification information matches the first identification information stored in the storage unit 112, the control unit 110 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62.

[0156] When a wireless connection is established with the second wireless communication unit 62, the control unit 110 causes the display unit 118 to display a settings screen (see reference). Figure 5 That is, the program 200 installed on the portable information terminal 100 causes the portable information terminal 100 to perform an initial setting step, that is, when the setting tag 150 storing the inherent first identification information of the second wireless communication unit 62 is read, the initial setting step of the toilet device 20 is performed.

[0157] If the combination setting button 116a is selected in the initial setting step (setting screen), the control unit 110 causes the display unit 118 to display a screen for reading the usage tag 160. In S15, the second identification information is acquired. That is, the administrator reads the usage tag 160 containing the second identification information through the acquisition unit 124 of the portable information terminal 100. The control unit 110 of the portable information terminal 100 causes the storage unit 112 to store the acquired second identification information.

[0158] In the next step, S16, a write signal for the second identification information is sent. The storage unit 112 of the portable information terminal 100 stores a program 200 that causes the wireless communication unit 114 to automatically send a write signal for the second identification information when the user tag 160 is acquired. Therefore, when the portable information terminal 100 acquires the user tag 160, it sends the second identification information stored in the user tag 160.

[0159] That is, the program 200 installed on the portable information terminal 100 performs the following combined steps: when the usage tag 160 storing the modifiable second identification information of the second wireless communication unit 62 is read in the initial setting step, a write signal for the second identification information is sent.

[0160] It should be noted that the write signal for the second identification information is not limited to automatic transmission; it can also be sent based on the administrator's operation. If the control unit 110 sends the write signal for the second identification information, it causes the display unit 118 to return to the setting screen and then ends the process.

[0161] The control unit 40 of the toilet device 20 causes the storage unit 42 to store the received second identification information. It should be noted that if the storage unit 42 stores different second identification information, it rewrites (overwrites) the new second identification information. This forms a combination (association) between the tag 160 and the second wireless communication unit 62. If the second wireless communication unit 62 stores the second identification information, it sets both the first and second identification information as its own identification information. Furthermore, the second wireless communication unit 62 continuously outputs the first and second identification information.

[0162] If the control unit 40 stores the second identification information in the storage unit 42, the second wireless communication unit 62 can send a combination completion signal. If the control unit 110 of the portable information terminal 100 receives the combination completion signal, it can display on the display unit 118 a message such as "Combination setting of toilet device and user ID completed." Furthermore, by operating the confirmation button 116e, the control unit 110 of the portable information terminal 100 can return the display unit 118 to the settings screen.

[0163] Next, refer to Figure 12 The following describes the scenario where users activate the functions of the toilet unit 20 using their own portable information terminal 100. It should be noted that the same control procedures are applied during trial runs conducted by administrators.

[0164] First, the user entering the toilet TR activates the remote operation program 200 (application) stored in the storage unit 112. Alternatively, the user can activate the remote operation program 200 (application) stored in the storage unit 112 by reading the user tag 160 through the acquisition unit 124 within the application. It should be noted that if the application is not installed on the user's portable information terminal 100, the application can be acquired (downloaded) via the Internet when the user tag 160 is read through the portable information terminal 100.

[0165] In step S21, second identification information is acquired. That is, the user reads the usage tag 160 installed on the wall or other surface of the toilet TR using the acquisition unit 124 of the portable information terminal 100. The control unit 110 of the portable information terminal 100 causes the storage unit 112 to store the acquired second identification information.

[0166] In step S22, it is determined whether the second identification information transmitted (output) from the second wireless communication unit 62 has been received. When the administrator associates the second identification information with the toilet device 20 (second wireless communication unit 62), the second wireless communication unit 62 continuously outputs (transmits) the first identification information and the second identification information. Therefore, the portable information terminal 100 receives the second identification information as long as it enters the detection range of the second wireless communication unit 62.

[0167] Furthermore, if the condition in S22 is "yes," meaning it is determined that the second identification information has been received, then proceed to S23. On the other hand, if the condition in S22 is "no," meaning it is determined that the second identification information has not been received, then the process ends.

[0168] In the next step, S23, it is determined whether the acquired second identification information is consistent with the received second identification information. That is, the control unit 110 compares the second identification information stored in the storage unit 112 with the received second identification information.

[0169] Furthermore, if S23 is "Yes," meaning it is determined that the acquired second identification information matches the received second identification information, then proceed to S24. Conversely, if S23 is "No," meaning the acquired second identification information does not match the received second identification information, then the process ends. Inconsistent second identification information could occur, for example, receiving second identification information from a second wireless communication unit 62 located in another toilet TR, or receiving second identification information not associated with a toilet TR. It should be noted that in S22 and S23, for example, the portable information terminal 100 monitors the reception of the second identification information for a predetermined time after reading the usage tag 160.

[0170] In S24, a wireless connection is established between the portable information terminal 100 and the second wireless communication unit 62. Specifically, the control unit 110 executes a connection establishment step, which establishes a connection with the second wireless communication unit 62 when a user tag 160 storing modifiable second identification information of the second wireless communication unit 62 is read. More specifically, the control unit 110 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62 when the received second identification information matches the second identification information stored in the storage unit 112.

[0171] It should be noted that, in addition to comparing the second identification information, the control unit 110 can also compare the first identification information to determine whether a wireless connection has been established. Specifically, for example, if the received second identification information matches the second identification information stored in the storage unit 112, the portable information terminal 100 communicates with the control unit 40. At this time, the control unit 40 sends the first identification information and information obtained by encrypting the first identification information to the portable information terminal 100. The control unit 110 encrypts the first identification information received from the control unit 40 in the same way as the control unit 40. Furthermore, the control unit 110 determines whether the encrypted information matches the information obtained by encrypting the first identification information received from the control unit 40. If the first identification information matches, the control unit 110 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62. In this case, the comparison of the first identification information can be performed by the control unit 40.

[0172] When a wireless connection is established with the second wireless communication unit 62, the control unit 110 causes the display unit 118 to display operation buttons for activating the functional units of the toilet device 20 (see reference). Figure 9 That is, the program 200 installed on the portable information terminal 100 performs the usage steps, namely, when a wireless connection is established with the second wireless communication unit 62, the display unit 118 displays the operation buttons of the function unit of the toilet device 20.

[0173] It should be noted that the operation buttons displayed on the display unit 118 show the state set by the administrator during the initial steps via display settings. Therefore, the control unit 110 causes the display unit 118 to display the operation buttons based on the display setting command signal sent from the second wireless communication unit 62.

[0174] In this case, the portable information terminal 100 can receive a command signal containing information related to display settings from the second wireless communication unit 62 during the establishment of a wireless connection with the second wireless communication unit 62 (during S23). Furthermore, by establishing a wireless communication connection between the portable information terminal 100 and the second wireless communication unit 62, a command signal containing information related to display settings can be sent from the second wireless communication unit 62, and the portable information terminal 100 can receive this command signal.

[0175] Thus, the user can operate various functions of the toilet appliance 20 through their portable information terminal 100. For example, when the flush button 116g is pressed, a toilet cleaning command signal is sent from the portable information terminal 100. Based on the toilet cleaning command signal, the control unit 40 activates the toilet cleaning device 79 to clean the toilet 10.

[0176] In the above embodiment, the initial setup was described as the administrator communicating with the second wireless communication unit 62 via the setup tag 150. However, this embodiment is not limited to this. For example, the initial setup can be performed by connecting all of the administrator's portable information terminals to the toilet unit via a wired connection. Furthermore, the initial setup can be performed via the Internet from a location far from the toilet unit (e.g., the management office). In such cases, the setup tag 150, which stores the first identification information, is not required.

[0177] Furthermore, in the above embodiment, the case of writing the second identification information by reading the setting tag 150 was described as an example. However, this embodiment is not limited to this; for example, it can be performed through input operations from portable information terminals owned by the administrator.

[0178] Furthermore, the second identification information may include specific instruction information. For example, the second identification information may include instruction information to prohibit the operation of functional parts of the toilet device 20, or instruction information prohibiting overwriting that can only be overwritten using specific second identification information. Thus, the administrator can, for example, temporarily disable the use of the toilet system 5. And only a specific administrator can restore the toilet system 5.

[0179] Furthermore, for example, the second identification information can include information for switching to an operating screen designed for the elderly. Thus, for example, the user can select the operating screen using their own portable information terminal. Additionally, either the first or second identification information can use encrypted information.
