As shown in FIG. 3, the remote controller 60 includes a control unit 61, a memory 62, an operation unit 63 (operation button 63A and assignment button 63B), a communication unit 64, a display unit 65, a battery 66, and a pulse wave sensor 67. Have. The control unit 61 is configured as a known computer and functions as an information processing apparatus that controls the entire remote controller 60. The control unit 61 is connected to a memory 62, an operation unit 63, a communication unit 64, a display unit 65, a battery 66, a pulse wave sensor 67, and the like. The control unit 61 outputs a control signal for operating the display unit 65, the pulse wave sensor 67, and the like. The memory 62 is a known memory, and stores in advance a system program that can control each functional device such as the pulse wave sensor 67. The operation unit 63 transmits an operation signal to the control unit 61 in accordance with an operation by the user.

As shown in FIG. 3, the control unit 61 includes the functions of an estimation unit 61A, an activation unit 61B, and a stop unit 61C. Each function executed by the control unit 61 may be realized by software processing by a CPU or the like, or may be realized by a hardware circuit. Each function may be realized by separate devices or may be realized by a common device.

The estimation unit 61A is a part having a function of estimating that at least one of defecation and urination has been completed. Specifically, when the supply control unit 51A of the toilet seat device 30 controls the supply operation of the flush water by the toilet bowl cleaning unit 41, the estimation unit 61A estimates that at least one of defecation or urination has been completed. That is, when acquiring the operation signal of the toilet bowl cleaning by operating the operation button 63A, the estimation unit 61A performs the operation of cleaning the stool (stool and urine) by at least one of the defecation and urination being completed by the user. It is estimated that at least one of defecation or urination has been completed.

The activation unit 61B is a portion having a function of activating the pulse wave sensor 67 when it is estimated by the estimation unit 61A that at least one of defecation or urination has been completed. Specifically, when acquiring the operation signal for toilet bowl cleaning by operating the operation button 63A, the activation unit 61B activates the pulse wave sensor 67.

When the remote controller 60 receives information indicating that the user has removed the seat 31 from the toilet seat 31 by the time when the predetermined time period has elapsed, the pulse wave sensor 67 is stopped. The stop portion 61C does not irradiate light from the light emitting element of the pulse wave sensor 67, and makes the light receiving element unable to receive light, thereby stopping the pulse wave sensor 67.

Next, the flow of control executed by the remote controller 60 will be described with reference to FIG. FIG. 4 is a flowchart showing the flow of control executed by the remote controller 60. The remote controller 60 starts the process of FIG. 4 as the user performs the toilet flush operation in a state where the user is seated on the toilet seat 31 (step (step) S11). In step S11, the toilet bowl cleaning operation is performed by the user pressing the operation button 63A. After step S11, the remote controller 60 transmits a toilet bowl cleaning signal instructing toilet bowl cleaning to the toilet seat device 30 (step S12). The toilet seat device 30 receives the toilet flush signal and performs the toilet flush process. Specifically, the toilet seat device 30 supplies wash water to the toilet bowl 21 by the toilet bowl cleaning unit 41, and the wash water in which stool (stool and urine) in the toilet bowl 21 is retained in the reservoir water unit And drain into drainage.

After step S12, the remote controller 60 activates the pulse wave sensor 67 (step S13). That is, when the toilet cleaning operation is performed in step S11, the remote controller 60 activates the pulse wave sensor 67 on the assumption that at least one of defecation or urination has been completed. The remote controller 60 emits light from the light emitting element of the pulse wave sensor 67, makes the light receiving element capable of receiving light, and brings the pulse wave sensor 67 into an activated state. After step S13, the remote controller 60 performs notification to prompt pulse wave measurement using the pulse wave sensor 67 (step S14). Specifically, the remote controller 60 causes the display unit 65 to display a message prompting measurement of the pulse wave (for example, display of a comment such as "Please put your finger on the pulse wave sensor").

After step S14, the remote controller 60 determines whether the pulse wave has been measured by the pulse wave sensor 67 (step S15). Specifically, the remote controller 60 determines whether or not a fingertip is placed on the finger placement unit 67A. For example, when the light is emitted from the light emitting element and the light is received by the light receiving element, the remote controller 60 reflects the light emitted from the light emitting element by the fingertip on the finger rest portion 67A and received by the light receiving element. In this case, it is determined that the fingertip is placed on the finger placement portion 67A. The pulse wave sensor 67 starts measuring a pulse wave (data of pulse waveform) when the finger is placed on the finger placement portion 67A. Specifically, the pulse wave sensor 67 measures the time change of the amount of light received by the light receiving element as the pulse waveform data. If the remote controller 60 determines that the pulse wave has been measured by the pulse wave sensor 67, the process proceeds to step S19.

On the other hand, when the remote controller 60 determines that the pulse wave is not measured by the pulse wave sensor 67 in step S15, the process proceeds to No, and determines whether the signal regarding the seat departure is received from the toilet seat device 30 ( Step S16). When the user leaves the toilet seat 31, the toilet seat device 30 detects a state in which the user leaves the toilet seat 31 by the seating detection unit 43. The toilet seat device 30 transmits a signal regarding the remote seat to the remote controller 60. In step S16, specifically, after activating the pulse wave sensor 67 (after step S13), the remote controller 60 determines whether or not a signal regarding departure has been received. If the remote controller 60 determines that the signal relating to the departure has been received, the process proceeds to Yes, stops the pulse wave sensor 67 (step S18), and ends the process illustrated in FIG. On the other hand, when it is determined that the remote controller 60 does not receive the signal related to the departure, the process proceeds to No, and a predetermined time (for example, a predetermined time from the time when the notification for prompting pulse wave measurement by the display unit 35 is performed) It is determined whether or not (step S17). If the remote controller 60 determines that the predetermined time has elapsed, the process proceeds to Yes and performs the process of step S18. On the other hand, if it is determined that the predetermined time has not elapsed, the remote controller 60 proceeds to No and performs the process of step S15 again.

In step S19, the remote controller 60 causes the display unit 65 to display the measurement result of the pulse waveform. For example, the remote controller 60 determines the age of the blood vessel, the degree of stress (stress), etc. specified by a known method (for example, the method shown in JP 2012-19926 A, etc.) based on the measured pulse waveform data. The display unit 65 displays information related to pulse wave waveform data. Subsequently, the remote controller 60 stops the pulse wave sensor 67 (step S20). Specifically, the remote controller 60 does not irradiate light from the light emitting element of the pulse wave sensor 67 and does not receive light by the light receiving element.

After step S20, the remote controller 60 determines whether or not a signal relating to departure has been received from the toilet seat device 30 (step S21). When the user leaves the toilet seat 31, the toilet seat device 30 detects a state in which the user leaves the toilet seat 31 by the seating detection unit 43. The toilet seat device 30 transmits a signal regarding the remote seat to the remote controller 60. The toilet seat device 30 detects a state in which the user leaves the toilet seat 31 by the seating detection unit 43. In step S21, specifically, after the measurement result is displayed by the display unit 65 (after step S19), the remote controller 60 determines whether or not the signal regarding the departure has been received. If it is determined that the remote control 60 has received a signal relating to leaving from the toilet seat device 30, the process proceeds to Yes, and the process of step S23 is performed. In step S23, the remote controller 60 ends the display of the measurement result displayed by the display unit 65 in step S20. After the process of step S23, the process illustrated in FIG. 4 ends.

On the other hand, if the remote controller 60 determines in step S21 that the signal relating to the seat departure has not been received from the toilet seat device 30, the process proceeds to No and predetermined time (for example, the time when the pulse wave sensor 67 is stopped (step S20 It is determined whether or not a predetermined period of time from when the process of (1) is performed has elapsed (step S22). For example, the remote controller 60 determines whether 30 seconds have elapsed since the pulse wave sensor 67 was stopped. If the remote controller 60 determines that the predetermined time has elapsed, the process proceeds to Yes, performs the process of step S23, and ends the process illustrated in FIG. On the other hand, when determining that the predetermined time has not elapsed, the remote controller 60 proceeds to No, and performs the process of step S21 again.

Hereinafter, the effects of the present configuration will be illustrated.
