The control unit 110 reads various programs and data stored in the storage unit 42 and sequentially processes them, thereby comprehensively controlling the operation of each unit of the portable information terminal 100 .

The wireless communication section 114 performs wireless communication with the second wireless communication section 62 of the toilet seat device 20 . A wireless communication device conforming to the same communication standard as the second wireless communication unit 62 is used for the wireless communication unit 114 . Wireless communication section 114 is connected to control section 110 . Radio communication section 114 inputs a received signal received from second radio communication section 62 of toilet seat device 20 to control section 110 , and transmits a transmission signal received from control section 110 to second radio communication section 62 of toilet seat device 20 . Send to

Operation unit 116 receives an input of an operation instruction from a user or the like. For example, a touch panel is used for the operation unit 116 . The operation unit 116 may be, for example, a mechanical switch or other sensor, or may be configured by combining these. Operation unit 116 is connected to control unit 110 . Operation unit 116 inputs the input operation instruction to control unit 110 . The control unit 110 controls the operation of each unit such as the wireless communication unit 114 according to an operation instruction input from the operation unit 116, for example.

The display unit 118 displays various operation screens and the like. A display device such as a liquid crystal display or an organic EL display is used for the display unit 118, for example. The display unit 118 is connected to the control unit 110 and performs various displays under the control of the control unit 110 . For example, when the operation unit 116 is a touch panel, the operation unit 116 is provided over the display unit 118 .

The speaker 120 outputs various sounds. The speaker 120 is connected to the control unit 110 and outputs various sounds under the control of the control unit 110 .

Microphone 122 converts the input sound into an electrical signal. Microphone 122 is connected to control unit 110 and inputs the converted electric signal to control unit 110 .

The storage unit 112 stores a toilet seat device remote control program 200 for remotely controlling the toilet seat device 20 with the mobile information terminal 100 . In other words, the portable information terminal 100 is installed with the toilet seat apparatus remote control program 200 .

For example, in response to an instruction to activate the toilet seat device remote control program 200 from the operation unit 116, the control unit 110 reads out the toilet seat device remote control program 200 from the storage unit 112, and performs remote control based on the toilet seat device remote control program 200. Remote operation of the toilet seat device 20 is enabled by executing the operation of the mode.

In order to remotely operate the toilet seat device 20 with the mobile information terminal 100, it may be necessary to perform pairing between the mobile information terminal 100 and the toilet seat device 20 in advance. When pairing is not performed, for example, after the toilet seat device remote control program 200 is activated, information on the toilet seat device 20 that can be paired is displayed on the display unit 118 . For example, when there are a plurality of toilet seat devices 20 that can be paired within the communication range of the wireless communication unit 114 , information on the plurality of toilet seat devices 20 is displayed on the display unit 118 .

The user selects the desired toilet seat device 20 to be paired from the information of the toilet seat device 20 displayed on the display unit 118 and inputs the selection result to the control unit 110 via the operation unit 116 . When the selection result is input from the operation unit 116 , the control unit 110 performs pairing with the selected toilet seat device 20 . After pairing with the toilet seat device 20 is completed, the control unit 110 starts communication connection with the toilet seat device 20 . As a result, remote control of the toilet seat device 20 by the mobile information terminal 100 becomes possible.

Once pairing with the toilet seat device 20 is performed, for example, ID information representing the toilet seat device 20 is stored in the storage unit 112, and subsequent pairing becomes unnecessary. Therefore, when the toilet seat device remote control program 200 is started, if the paired toilet seat device 20 exists within the communication range of the wireless communication unit 114, the communication connection with the toilet seat device 20 is started, and the pairing is performed. The toilet seat device 20 can be remotely operated without performing

FIG. 4 is an explanatory diagram schematically showing an example of a display screen displayed on the display unit of the mobile information terminal.
As shown in FIG. 4 , the control unit 110 of the mobile information terminal 100 displays an operation screen OS for operating the toilet seat device 20 on the display unit 118 while being connected for communication with the toilet seat device 20 . The operation screen OS includes, for example, a bottom washing button for instructing execution of bottom washing, a bidet washing button for instructing execution of bidet washing, a setting button for setting hot water temperature, toilet seat temperature, etc., and a toilet seat Various buttons are provided, such as a disconnect button for disconnecting the communication connection with device 20 . The user inputs desired operation instructions to the control unit 110 by operating various buttons via the operation unit 116 .

When an operation instruction regarding the operation of the toilet seat device 20 is input from the operation unit 116 by operating the flush button or the like, the control unit 110 transmits a signal from the wireless communication unit 114 to the toilet seat device 20, and performs an operation corresponding to the corresponding operation. to the toilet seat device 20.

Upon receiving a signal from mobile information terminal 100, control unit 40 of toilet seat device 20 performs an operation corresponding to the signal. Upon receiving a signal from the mobile information terminal 100, the control unit 40 responds to the signal by operating the toilet lid opening/closing device 70, the toilet seat opening/closing device 71, the toilet seat heater 72, the solenoid valve 73, the hot water heater 74, the nozzle driving device 75, Any one of the deodorizing device 76, the indoor heating device 77, the lighting device 78, the toilet cleaning device 79, and the hot air blower 80 is operated. Thereby, the toilet seat device 20 can be remotely operated based on the operation of the portable information terminal 100 .

On the other hand, when an operation instruction to disconnect the communication connection is input from the operation unit 116 by operating the disconnection button, the control unit 110 executes processing for disconnecting the communication connection with the toilet seat device 20 . As a result, the control unit 110 of the mobile information terminal 100 and the control unit 40 of the toilet seat device 20 disconnect from each other.

In this way, when the control unit 40 of the toilet seat device 20 receives a signal instructing disconnection of the communication connection from the mobile information terminal 100, the control unit 40 establishes the communication connection with the mobile information terminal 100 in response to the instruction from the mobile information terminal 100. disconnect. The control unit 40 also disconnects the communication connection with the mobile information terminal 100 when the mobile information terminal 100 is out of the communication range of the second wireless communication unit 62 .

FIG. 5 is a flow chart schematically showing an example of the operation of the toilet system according to the first embodiment.
When the control unit 40 of the toilet seat device 20 starts communication connection with the mobile information terminal 100 and executes the operation in the mobile information terminal operation mode, the signal received from the mobile information terminal 100 via the second wireless communication unit 62 is Based on this, the operation of a plurality of operation units is controlled, and a disconnection determination of the communication connection state with the portable information terminal 100 shown in FIG. 5 is started (step S101 in FIG. 5).

When starting the disconnection determination, the control unit 40 determines whether or not the first condition that the non-detection state in which the seating detection sensor 53 does not detect the seating continues for a first predetermined time or longer (step in FIG. 5) is satisfied. S102). When determining that the first condition is not satisfied, the control unit 40 repeats the process of step S102.

On the other hand, if the control unit 40 determines that the first condition is satisfied, then it determines whether the second condition that the mobile information terminal 100 has not been operated for a second predetermined time or longer has been satisfied (see FIG. 5). step S103). In this example, the determination of the second condition is performed after the determination of the first condition, but on the contrary, the determination of the first condition may be performed after the determination of the second condition.

For example, the control unit 40 measures the time from the input of a signal from the portable information terminal 100 to the input of the next signal, and determines that the second condition is satisfied when this time is equal to or longer than the second predetermined time. do.

For example, the control unit 110 of the mobile information terminal 100 is caused to measure the time from the operation of the operation unit 116 to the next operation, and when this time is equal to or longer than the second predetermined time, the mobile information terminal 100 to the toilet seat device 20 A non-operation signal is transmitted to the control unit 40 of the . The control unit 40 of the toilet seat device 20 may determine that the second condition is satisfied according to the input of the non-operation signal from the mobile information terminal 100 .

In this manner, the timing of the second predetermined time may be performed on the toilet seat device 20 side or may be performed on the portable information terminal 100 side. Moreover, the operation/non-operation of the mobile information terminal 100 is not limited to the operation for operating the action unit of the toilet seat device 20 . For example, to prevent the mobile information terminal 100 from going into a sleep state (display off state), an operation of touching a portion of the operation unit 116, which is a touch panel, unrelated to the remote operation of the toilet seat device 20 may be included. In this way, the operation of the mobile information terminal 100 may include not only an operation for operating the action unit of the toilet seat device 20 but also an operation for operating the mobile information terminal 100, for example. The operation/non-operation of the mobile information terminal 100 may be any operation on the operation unit 116, for example.

For example, when an operation for operating the portable information terminal 100 is also included, if the toilet seat device 20 attempts to time the second predetermined time, an operation of the portable information terminal 100 unrelated to the remote operation of the toilet seat device 20 is performed. , must also be transmitted to the toilet seat device 20 one by one. Therefore, when an operation for operating the mobile information terminal 100 is included, it is preferable that the mobile information terminal 100 counts the second predetermined time. Thereby, transmission of a signal from the portable information terminal 100 to the toilet seat device 20 can be suppressed. For example, an increase in power consumption in the mobile information terminal 100 can be suppressed.

When determining that the second condition is not satisfied, the control unit 40 of the toilet seat device 20 returns to the process of step S102 and determines again whether or not the first condition is satisfied. On the other hand, when determining that the second condition is satisfied, the control unit 40 executes automatic disconnection processing for automatically disconnecting the communication connection state with the portable information terminal 100 (step S104 in FIG. 5). That is, when the first condition and the second condition are satisfied, the control unit 40 executes the automatic disconnection process and automatically disconnects the communication connection state with the mobile information terminal 100 .

The control unit 40, for example, based on a signal input from an operation unit of the toilet seat device 20 such as the remote controller 28 or an operation panel (not shown) or a signal input from the mobile information terminal 100, controls the first predetermined time and the second time. 2 Change the predetermined time. For example, the control unit 40 causes the storage unit 42 to store the value of the first predetermined time and the value of the second predetermined time, and stores the value stored in the storage unit 42 according to the input from the operation unit or the mobile information terminal 100. By rewriting, the first predetermined time and the second predetermined time are changed. Thereby, the first predetermined time and the second predetermined time can be set to arbitrary values. The second predetermined time can be set to a value different from the first predetermined time.

As described above, in the toilet seat device 20 according to the present embodiment, by executing the automatic disconnection process, even if the previous user forgets to disconnect the communication connection, the next user cannot connect to the communication connection. It is possible to suppress the situation where Further, by executing the automatic disconnection process when both the first condition and the second condition are satisfied, for example, when excretion takes a long time and the portable information terminal 100 is not operated for a predetermined time. Also, it is possible to prevent disconnection of the communication connection before the user has finished using the toilet. Therefore, it is possible to appropriately execute the automatic disconnection process after using the toilet while suppressing unintentional disconnection of the communication connection while using the toilet.

Moreover, in the toilet seat device 20, the first predetermined time and the second predetermined time can be changed. By setting the second predetermined time to be short, the automatic disconnection process can be executed early, and it is possible to more appropriately prevent the next user from being unable to connect to the communication. For example, when the toilet seat device 20 is installed at a public site, the first predetermined time and the second predetermined time are set to approximately 10 seconds (for example, 1 second or more and 20 seconds or less). As a result, it is possible to more appropriately prevent the next user from being unable to connect to the communication.

Then, for example, when the toilet seat device 20 is installed in a residential site where continuous use is unlikely to occur frequently, by setting the first predetermined time and the second predetermined time longer, it is possible to prevent the communication connection state from occurring unintentionally while using the toilet. can be suppressed more appropriately. For example, when the toilet seat device 20 is installed at a residential site, the first predetermined time and the second predetermined time are set to about 90 seconds (for example, 80 seconds or more and 100 seconds or less). As a result, unintentional disconnection of the communication connection while using the toilet can be more appropriately suppressed.

For example, in the case of a user who excretes for a long time, it is preferable that the second predetermined period of non-operation of the mobile information terminal 100 is longer. On the other hand, if the first predetermined time for seating non-detection is also lengthened, the execution of the automatic disconnection process will be delayed, increasing the possibility that the next user will be unable to connect for a while. In this toilet seat device 20, the first predetermined time and the second predetermined time can be set to different values. The automatic disconnection process can be executed early after using the toilet while suppressing the For example, the first predetermined time is set to approximately 30 seconds (eg, 20 seconds to 40 seconds), and the second predetermined time is set to approximately 90 seconds (eg, 80 seconds to 100 seconds). As a result, the automatic disconnection process can be executed early after using the toilet while suppressing unintended disconnection.

FIG. 6 is a flowchart schematically showing an example of another operation of the toilet system according to the first embodiment.
As shown in FIG. 6, when the control unit 40 of the toilet seat device 20 starts to determine whether the communication connection state with the portable information terminal 100 is disconnected, the non-detection state in which the seating detection sensor 53 does not detect seating is the first state. It is determined whether or not it has continued for a first extension time longer than a predetermined time (steps S201 and S202 in FIG. 6).

When determining that the control unit 40 has not continued for the first extension time or longer, the control unit 40 determines whether or not the non-operation of the mobile information terminal 100 has continued for the second extension time longer than the second predetermined time (FIG. 6). step S203). The order of steps S202 and S203 is random.

When the control unit 40 determines that the non-detection state in which the seating detection sensor 53 does not detect the seating has continued for the first predetermined time or longer when determining that the control unit 40 has not continued for the second extended time or longer, whether or not the first condition is satisfied. is determined (step S204 in FIG. 6). When determining that the first condition is not satisfied, the control unit 40 returns to the process of step S202.

On the other hand, if the control unit 40 determines that the first condition is satisfied, then it determines whether the second condition that the mobile information terminal 100 has not been operated for a second predetermined time or longer has been satisfied (see FIG. 6). step S205).

When determining that the second condition is not satisfied, the control unit 40 returns to the process of step S202. On the other hand, when determining that the second condition is satisfied, the control unit 40 executes automatic disconnection processing for automatically disconnecting the communication connection state with the portable information terminal 100 (step S206 in FIG. 6). That is, when the first condition and the second condition are satisfied, the control unit 40 executes the automatic disconnection process and automatically disconnects the communication connection state with the mobile information terminal 100 .

If the controller 40 determines in step S202 that the connection has continued for the first extension time or longer, and if it determines in step S203 that the connection has continued for the second extension time or longer, the control unit 40 proceeds to the process of step S206 to perform the automatic disconnection process. to run.

In this manner, in the communication connection state in which the second wireless communication unit 62 is connected to the mobile information terminal 100, the control unit 40 determines that the state in which the seating detection sensor 53 has not detected the seating is longer than the first predetermined time. The automatic disconnection process is executed when the non-operation of the portable information terminal 100 continues for a long first extension time or longer, or when the non-operation of the mobile information terminal 100 continues for a second extension time longer than the second predetermined time. As a result, for example, even when the seating detection sensor 53 erroneously detects that a person is seated, the automatic disconnection process can be executed appropriately.

FIG. 7 is a flowchart schematically showing an example of another operation of the toilet system according to the first embodiment;
As shown in FIG. 7 , when the control unit 40 of the toilet seat device 20 starts to determine disconnection of the communication connection state with the portable information terminal 100, the non-detection state in which the seating detection sensor 53 does not detect seating is the first state. It is determined whether or not the first condition continued for a predetermined time or longer is satisfied (steps S301 and 302 in FIG. 7). When determining that the first condition is not satisfied, the control unit 40 repeats the process of step S302.

On the other hand, if the control unit 40 determines that the first condition is satisfied, then it determines whether the second condition that the mobile information terminal 100 has not been operated for a second predetermined time or longer has been satisfied (see FIG. 7). step S303). When determining that the second condition is not satisfied, the control unit 40 returns to the process of step S302.

On the other hand, when the control unit 40 determines that the second condition is satisfied, subsequently, the third condition that the non-detection state in which the first human body detection sensor 51 does not detect a human body continues for a third predetermined time or more is satisfied. (step S304 in FIG. 7). Note that the determination of the first condition, the determination of the second condition, and the determination of the third condition are performed in random order.

When determining that the third condition is not satisfied, the control unit 40 returns to the process of step S302. On the other hand, when determining that the third condition is satisfied, the control unit 40 executes automatic disconnection processing for automatically disconnecting the communication connection state with the portable information terminal 100 (step S305 in FIG. 7). That is, the control unit 40 executes the automatic disconnection process and automatically disconnects the communication connection state with the mobile information terminal 100 when all of the first condition, the second condition, and the third condition are satisfied.

By executing the automatic disconnection process when all three conditions are satisfied in this way, unintended disconnection can be suppressed more appropriately, and the automatic disconnection process can be executed after using the toilet.

In this example, the first human body detection sensor 51 that detects a human body approaching the toilet seat device 20 is used in determining the third condition. Without being limited to this, for example, the second human body detection sensor 52 that detects a human body standing in front of the toilet seat device 20 (toilet bowl 12) may be used to determine the third condition.

For example, based on a signal input from an operation unit of the toilet seat device 20 such as the remote control 28 or an operation panel (not shown) or a signal input from the mobile information terminal 100, the control unit 40 controls the first predetermined time, the second The second predetermined time and the third predetermined time are changed. For example, the control unit 40 causes the storage unit 42 to store the value of the first predetermined time, the value of the second predetermined time, and the value of the third predetermined time, and stores them according to the input from the operation unit or the mobile information terminal 100. By rewriting the values stored in the unit 42, the first predetermined time, the second predetermined time, and the third predetermined time are changed. Thereby, the first predetermined time, the second predetermined time, and the third predetermined time can be set to different values.

For example, in the case of a user who excretes for a long time, it is preferable that the second predetermined period of non-operation of the mobile information terminal 100 is longer. On the other hand, if the first predetermined time period for non-seating detection and the third predetermined time period for non-detection of a human body are also lengthened, the execution of the automatic disconnection process will be delayed, and there is a possibility that the next user will be unable to connect to the communication for a while. becomes higher.

Further, since there is a replenishment of toilet paper and an operation to wipe the bottom, it is preferable that the first predetermined time during which the seating is not detected is slightly longer. On the other hand, if the third predetermined time period during which the human body is not detected is also lengthened, the execution of the automatic disconnection process will be delayed, increasing the possibility that the next user will be unable to connect for a while.

By enabling the first predetermined time, the second predetermined time, and the third predetermined time to be set to different values, for example, the first predetermined time is medium, the second predetermined time is the longest, and the third predetermined time is the longest. By making the time as short as possible, the automatic disconnection process can be executed early after using the toilet while suppressing unintended disconnection.

For example, the first predetermined time is set to approximately 30 seconds (eg, 20 seconds to 40 seconds), the second predetermined time is set to approximately 90 seconds (eg, 80 seconds to 100 seconds), and the third predetermined time is is set to about 10 seconds (for example, 1 second or more and 20 seconds or less). As a result, the automatic disconnection process can be executed early after using the toilet while suppressing unintended disconnection.

FIG. 8 is a flowchart schematically showing an example of another operation of the toilet system according to the first embodiment;
As shown in FIG. 8 , when the control unit 40 of the toilet seat device 20 starts to determine disconnection of the communication connection state with the portable information terminal 100, the non-detection state in which the seating detection sensor 53 does not detect seating is the first state. It is determined whether or not it has continued for a first extension time longer than a predetermined time (steps S401 and S402 in FIG. 8).

When determining that the control unit 40 has not continued for the first extension time or longer, the control unit 40 determines whether or not the non-operation of the mobile information terminal 100 has continued for the second extension time longer than the second predetermined time (FIG. 8). step S403).

When the control unit 40 determines that the non-detection state in which the first human body detection sensor 51 does not detect a human body continues for a third extension time longer than the third predetermined time, the control unit 40 determines that it has not continued for the second extension time or longer. (Step S404 in FIG. 8). The order of steps S402, S403, and S404 is random.

When the control unit 40 determines that the non-detection state in which the seating detection sensor 53 does not detect the seating has continued for the first predetermined time or longer, if the control unit 40 determines that it has not continued for the third extension time or longer, the first condition is satisfied. is determined (step S405 in FIG. 8). When determining that the first condition is not satisfied, the control unit 40 returns to the process of step S402.

On the other hand, if the control unit 40 determines that the first condition is satisfied, then it determines whether the second condition that the mobile information terminal 100 has not been operated for a second predetermined time or longer has been satisfied (see FIG. 8). step S406). When determining that the second condition is not satisfied, the control unit 40 returns to the process of step S402.

On the other hand, when the control unit 40 determines that the second condition is satisfied, subsequently, the third condition that the non-detection state in which the first human body detection sensor 51 does not detect a human body continues for a third predetermined time or more is satisfied. It is determined whether or not (step S407 in FIG. 8).

When determining that the third condition is not satisfied, the control unit 40 returns to the process of step S402. On the other hand, when determining that the third condition is satisfied, the control unit 40 executes automatic disconnection processing for automatically disconnecting the communication connection state with the portable information terminal 100 (step S408 in FIG. 8). That is, the control unit 40 executes the automatic disconnection process and automatically disconnects the communication connection state with the portable information terminal 100 when all of the first, second, and third conditions are satisfied.

Further, if the control unit 40 determines that it has continued for the first extension time or more in step S402, if it determines that it has continued for the second extension time or more in step S403, or determines that it has continued for the third extension time or more in step S404. Also when it does, it progresses to the process of step S408 and performs an automatic disconnection process.

As a result, for example, even when the seating detection sensor 53 or the first human body detection sensor 51 erroneously detects a person and detects the presence of a person, the automatic disconnection process can be executed appropriately.

FIG. 9 is a flowchart schematically showing an example of another operation of the toilet system according to the first embodiment;
As shown in FIG. 9 , when the control unit 40 of the toilet seat device 20 starts to determine disconnection of the communication connection state with the mobile information terminal 100, the non-detection state in which the seating detection sensor 53 does not detect seating is the first state. When the non-operation of the portable information terminal 100 continues for a first extension time longer than the predetermined time, when the non-operation of the portable information terminal 100 continues for a second extension time longer than the second predetermined time, and when the first human body detection sensor 51 detects the human body. It is determined whether or not any two conditions are satisfied when the non-detection state continues for a third extension time longer than the third predetermined time (steps S501 and S502 in FIG. 9).

When determining that the control unit 40 does not satisfy the condition, the control unit 40 determines whether or not the first condition in which the non-detection state in which the seating detection sensor 53 does not detect the seating has continued for a first predetermined time or longer has been satisfied (FIG. 9). step S503). When determining that the first condition is not satisfied, the control unit 40 returns to the process of step S502.

On the other hand, when determining that the first condition is satisfied, the control unit 40 subsequently determines whether or not the second condition that the portable information terminal 100 has not been operated for a second predetermined time or longer has been satisfied (see FIG. 9). step S504). When determining that the second condition is not satisfied, the control unit 40 returns to the process of step S502.

On the other hand, when the control unit 40 determines that the second condition is satisfied, subsequently, the third condition that the non-detection state in which the first human body detection sensor 51 does not detect a human body continues for a third predetermined time or more is satisfied. (step S505 in FIG. 9).

When determining that the third condition is not satisfied, the control unit 40 returns to the process of step S502. On the other hand, when determining that the third condition is satisfied, the control unit 40 executes automatic disconnection processing for automatically disconnecting the communication connection state with the portable information terminal 100 (step S506 in FIG. 9). That is, the control unit 40 executes the automatic disconnection process and automatically disconnects the communication connection state with the portable information terminal 100 when all of the first, second, and third conditions are satisfied.

Further, if the control unit 40 determines in step S502 that any two conditions of the first extension time or longer, the second extension time or longer, and the third extension time or longer are satisfied, the process proceeds to step S506. , perform the automatic disconnection process.

As a result, for example, even when the seating detection sensor 53 or the first human body detection sensor 51 erroneously detects a person and detects the presence of a person, the automatic disconnection process can be executed appropriately. Further, by executing the automatic disconnection process when any two conditions are satisfied, unintended disconnection can be suppressed more appropriately.

(Second embodiment)
FIG. 10 is a perspective view schematically showing the toilet system according to the second embodiment.
It should be noted that the same reference numerals are given to the elements that are substantially the same in terms of function and configuration as those of the first embodiment, and detailed description thereof will be omitted.
As shown in FIG. 10, in the toilet system 2a, the toilet seat device 20 and the mobile information terminal 100 perform wireless communication via the communication device 4. As shown in FIG. The communication device 4 is, for example, a router.

In this example, the second wireless communication section 62 of the toilet seat device 20 wirelessly communicates with the communication device 4 . The wireless communication unit 114 of the mobile information terminal 100 performs wireless communication with the communication device 4 . The second wireless communication unit 62 of the toilet seat device 20 and the wireless communication unit 114 of the mobile information terminal 100 perform wireless communication with each other via the communication device 4 .

Note that, in this example, the toilet seat device 20 and the mobile information terminal 100 are connected for communication via one communication device 4 . Without being limited to this, the toilet seat device 20 and the portable information terminal 100 may be communicatively connected via a plurality of communication devices 4 .

As described with regard to the first embodiment, when the toilet seat device 20 and the mobile information terminal 100 are directly connected for communication, the communication connection can be made only within the radio wave range of the toilet seat device 20 and the mobile information terminal 100. cannot be done. On the other hand, as in this toilet system 2a, when one or more communication devices 4 are interposed between the toilet seat device 20 and the mobile information terminal 100, the toilet seat device 20 and the mobile information can be communicated from a farther position. It becomes possible to establish a communication connection with the terminal 100 .

FIG. 11 is a flow chart schematically showing an example of the operation of the toilet system according to the second embodiment.
When the control unit 40 of the toilet seat device 20 starts communication connection with the mobile information terminal 100 and executes the operation in the mobile information terminal operation mode, the signal received from the mobile information terminal 100 via the second wireless communication unit 62 is Based on this, the operation of a plurality of operation units is controlled, and determination of termination of the portable information terminal operation mode shown in FIG. 11 is started (step S601 in FIG. 11).

When starting the end determination, the control unit 40 determines whether or not the first condition that the non-detection state in which the seating detection sensor 53 does not detect the seating has continued for a first predetermined time or longer (step of FIG. 11) is satisfied. S602). When determining that the first condition is not satisfied, the control unit 40 repeats the process of step S602.

On the other hand, if the control unit 40 determines that the first condition is satisfied, then it determines whether the second condition that the mobile information terminal 100 has not been operated for a second predetermined time or longer has been satisfied (see FIG. 11). step S603).

When determining that the second condition is not satisfied, the control unit 40 returns to the process of step S602 and determines again whether or not the first condition is satisfied. On the other hand, when determining that the second condition is satisfied, the control unit 40 executes automatic termination processing for automatically terminating the mobile information terminal operation mode (step S604 in FIG. 11). That is, when the first condition and the second condition are satisfied, the control unit 40 executes the automatic termination process and automatically terminates the portable information terminal operation mode.

When the toilet seat device 20 and the mobile information terminal 100 perform wireless communication via the communication device 4 , communication connection between the toilet seat device 20 and the communication device 4 is performed in order to establish communication connection with the next mobile information terminal 100 . State cannot be disconnected. Therefore, when wirelessly communicating with the mobile information terminal 100 via the communication device 4, the control unit 40 of the toilet seat device 20 does not automatically disconnect the communication connection state as described above, but rather Perform an action that automatically exits terminal operation mode. In other words, the control unit 40 does not physically disconnect the communication connection with the mobile information terminal 100 , but logically disconnects the communication connection with the mobile information terminal 100 . As a result, even when performing wireless communication via the communication device 4 , communication connection can be established with the next mobile information terminal 100 via the communication device 4 .

In other words, the operation of FIG. 11 replaces the automatic disconnection process of the operation of FIG. 5 with an automatic end process. The replacement from the automatic disconnection process to the automatic end process is not limited to the operation in FIG. 5, and may be the operations described with reference to FIGS. 6 to 9. FIG.

(Third embodiment)
FIG. 12 is a flow chart schematically showing an example of the operation of the toilet system according to the third embodiment.
In the above-described first embodiment, an example in which the communication connection state is disconnected on the toilet seat device 20 side has been described. An example of disconnecting the communication connection state on the portable information terminal 100 side will be described below.

When the control unit 110 of the mobile information terminal 100 starts the operation in the remote control mode by activating the toilet seat device remote control program 200, the control unit 110 transmits a signal corresponding to the operation of the operation unit 116 to the toilet seat device 20, thereby operating the toilet seat device 20. While remote-controlling the operations of a plurality of operation units, it starts determining whether the communication connection state with the toilet seat device 20 shown in FIG. 12 is disconnected (step S701 in FIG. 12).

After starting the disconnection determination, the control unit 110 acquires information about the detection result of the seating detection sensor 53 from the toilet seat device 20 (step S702 in FIG. 12).

Based on the information about the detection result of the seating detection sensor 53 acquired from the toilet seat device 20, the control unit 110 determines the first condition that the non-detection state in which the seating detection sensor 53 does not detect the seating has continued for a first predetermined time or longer. is satisfied (step S703 in FIG. 12).

The information about the detection result of the seating detection sensor 53 is, for example, information indicating detection/non-detection of the seating detection sensor 53 . For example, the control unit 110 determines that the first condition is satisfied when a first predetermined time has passed since the seating detection sensor 53 switched from detection to non-detection.

The information about the detection result of the seating detection sensor 53 may be, for example, information indicating that the first predetermined time has passed. For example, the control unit 110 may determine that the first condition is satisfied when information indicating that the first predetermined time has passed has been obtained from the toilet seat device 20 . In this way, the actual timing of the first predetermined period of time may be performed on the mobile information terminal 100 side or may be performed on the toilet seat device 20 side.

If the control unit 110 determines that the first condition is not satisfied, the control unit 110 returns to the process of step S702. On the other hand, when determining that the first condition is satisfied, the control unit 110 subsequently determines whether or not the second condition that the mobile information terminal 100 has not been operated for a second predetermined time period or longer has been satisfied (see FIG. 12). step S704). For example, the control unit 110 determines that the second condition is satisfied when the non-operation time of the operation unit 116 continues for a second predetermined time or longer.

If the control unit 110 determines that the second condition is not satisfied, the control unit 110 returns to the process of step S702 and acquires information about the detection result of the seating detection sensor 53 . On the other hand, when determining that the second condition is satisfied, the control unit 110 executes automatic disconnection processing for automatically disconnecting the communication connection state with the toilet seat device 20 (step S705 in FIG. 12). That is, when the first condition and the second condition are satisfied, the control unit 110 executes the automatic disconnection process and automatically disconnects the communication connection state with the toilet seat device 20 .

In this manner, the automatic disconnection process may be performed on the toilet seat device 20 side, or may be performed on the portable information terminal 100 side. Even if the portable information terminal 100 side performs the automatic disconnection process in the same way as the toilet seat device 20 side, even if the previous user forgets to disconnect the communication connection, the next use can be performed. Therefore, it is possible to prevent a situation in which a person becomes unable to establish a communication connection. Further, by executing the automatic disconnection process when both the first condition and the second condition are satisfied, for example, when excretion takes a long time and the portable information terminal 100 is not operated for a predetermined time. Also, it is possible to prevent disconnection of the communication connection before the user has finished using the toilet. Therefore, it is possible to appropriately execute the automatic disconnection process after using the toilet while suppressing unintentional disconnection of the communication connection while using the toilet.

As described above, the toilet seat device remote control program 200 performs a step of acquiring information about the detection result of the seating detection sensor 53 from the toilet seat device 20 in a communication connection state in which the wireless communication unit 114 is connected to the toilet seat device 20 for communication (for example, , step S702 in FIG. 12), a first condition in which the seating detection sensor 53 has not detected a seating condition in the communication connection state for a first predetermined time or longer, and a second condition in which the portable information terminal 100 is not operated. a step of executing an automatic disconnection process for automatically disconnecting the communication connection state (for example, step S705 in FIG. 12) when both of a second condition that continues for a predetermined time or longer are satisfied, and a portable information terminal; 100 to run.

In FIG. 12, the operation after step S702 for acquiring information about the detection result of the seating detection sensor 53 from the toilet seat device 20 is substantially the same as the operation described with reference to FIG. The operations after step S702 are not limited to this, and may be substantially the same as the operations described with reference to FIGS.

10 and 11, when the portable information terminal 100 wirelessly communicates with the toilet seat device 20 via the communication device 4, the automatic disconnection process in step S705 is automatically switched to the remote operation mode. It may be replaced with an automatic termination process that terminates. However, in the case of the portable information terminal 100, it is not always necessary to continue the communication connection state with the communication device 4 after the use of the toilet device 10 is finished. Therefore, when the mobile information terminal 100 makes a determination, even when wireless communication with the toilet seat device 20 is performed via the communication device 4, automatic disconnection processing for automatically disconnecting the communication connection state is performed. good too.

The automatic disconnection process or the automatic end process may be performed by both the toilet seat device 20 and the mobile information terminal 100, for example. As a result, even if the previous user forgets to disconnect the communication connection, it is possible to more reliably prevent the next user from being unable to connect to the communication.
