The urination information measuring device 5 includes a measuring means control unit 54 and a urination information measuring means 55. The urination information measuring means 55 includes, for example, a sensor for measuring the water level in the bowl 22 and a pump for setting the water level. The measuring means control unit 54 is, for example, a circuit including an IC element, and controls the operation of the urination information measuring means 55.

The board unit 50 includes a radio wave receiving unit 51, an information cooperation unit 52 (logic board), and a toilet bowl cleaning control unit 53 (toilet bowl cleaning board). The information cooperation unit 52 and the toilet bowl cleaning control unit 53 are circuits including, for example, IC elements, respectively. The radio wave receiving unit 51 is, for example, an antenna board, and receives radio wave signals from the remote controllers 12 to 14 described above with respect to FIG. The radio wave receiving unit 51 transmits a signal related to an instruction from the remote controller to the information linking unit 52 based on the received radio wave signal.

The information cooperation unit 52 appropriately transmits a signal related to an instruction from the remote controller to the cleaning means control unit 405, the toilet bowl cleaning control unit 53, and the measuring means control unit 54.
The cleaning means control unit 405 controls the operation of the sanitary cleaning means 406 based on the signal acquired from the information cooperation unit 52. Further, the measuring means control unit 54 controls the operation of the urination information measuring means 55 based on the signal acquired from the information cooperation unit 52. Further, the toilet bowl cleaning control unit 53 controls the operation of the toilet bowl cleaning means 61 based on the signal acquired from the information cooperation unit 52 to perform toilet bowl cleaning.

Further, the information cooperation unit 52 acquires a signal regarding the operating state of the sanitary cleaning device 3 from the cleaning means control unit 405, and acquires a signal regarding the operating state of the toilet bowl cleaning means 61 from the toilet bowl cleaning control unit 53.
The signal relating to the operating state of the sanitary cleaning device 3 is information indicating whether or not the sanitary cleaning device 3 is performing local cleaning (for example, information indicating the open / closed state of the electromagnetic valve that controls the supply of cleaning water to the nozzle). Etc.) including. The signal regarding the operating state of the toilet bowl cleaning means 61 is information indicating whether or not the toilet bowl cleaning means 61 is cleaning the toilet bowl (for example, information indicating the open / closed state of the toilet bowl cleaning valve that controls the supply of cleaning water to the bowl 22). Etc.) including.

If the sanitary cleaning device 3 or the toilet bowl cleaning means 61 operates when measuring urination information, the measurement accuracy may decrease. For example, when the urine urine information measuring device 5 measures the urine volume by changing the water level in the bowl 22, when the washing water is supplied into the bowl 22 by the sanitary washing device 3 or the toilet bowl washing means 61, the water level in the bowl 22 Also changes with wash water.

On the other hand, the measuring means control unit 54 of the urination information measuring device 5 according to the embodiment acquires information on the operating state of the sanitary cleaning device 3 and information on the operating state of the toilet bowl cleaning means 61 from the information cooperation unit 52. .. The measuring means control unit 54 controls the measurement of urination information based on the information (operation information) acquired from the information cooperation unit 52. As a result, the urination information measuring device 5 can operate in cooperation with the operation of the sanitary cleaning device 3 and the toilet bowl cleaning means 61 in consideration of the operation. For example, the measuring means control unit 54 determines that the urination information is not measured when the local washing is performed and when the toilet bowl washing is performed. As a result, it is possible to prevent a decrease in measurement accuracy.

By the way, in general sanitary cleaning equipment, a plurality of models having different functions have been developed. For example, if there is concern about infectious diseases, the function of spraying hypochlorite water may be required, and in ladies' clinics, the function of emphasizing local cleaning may be requested. Therefore, it is desirable that various types of sanitary cleaning devices can be installed in the biological information measuring device. On the other hand, in the conventional biometric information measuring device, the sanitary cleaning device is integrated with the toilet bowl, and the function corresponding to the information cooperation unit 52 is built in the sanitary cleaning device. Many sanitary cleaning devices do not have a function corresponding to the information linking unit 52, and are not configured so that the operation of the sanitary cleaning device and the measurement of urination information can be linked in advance. Therefore, it has been difficult to install various types of sanitary cleaning devices in the biometric information measuring device.

On the other hand, the biological information measuring device 1 according to the embodiment has an information cooperation unit 52 provided separately from the sanitary cleaning device 3 on the outside of the outer shell (cover 3c) of the sanitary cleaning device 3. As a result, if the information cooperation unit 52 and the cleaning means control unit 405 of the sanitary cleaning device 3 are connected by a cable or the like, the operation of the sanitary cleaning device and the measurement of urination information can be linked. For example, even a sanitary cleaning device that is not configured in advance so that the operation of the sanitary cleaning device and the measurement of urine information can be linked with each other can be installed in the biological information measuring device. Therefore, various types of sanitary cleaning devices can be installed. Further, in the unlikely event that the information cooperation unit 52 breaks down, only the information cooperation unit 52 needs to be replaced, and the sanitary cleaning device 3 does not need to be replaced.

Further, for example, the measuring means control unit 54 stops the measurement of the urination information when the local washing is started and when the toilet bowl washing is started. As described above, in the biological information measuring device 1 according to the embodiment, the function as a normal toilet (toilet bowl cleaning and local cleaning) can be prioritized. As a result, usability can be improved. For example, even if the user forgets to press the measurement end switch of the remote controller 12 when measuring the urination information, the measurement of the urination information can be ended by operating the toilet bowl cleaning switch 13a. Further, by stopping the measurement of the urination information, it is possible to prevent water from flowing into the water level measuring tube 36, which will be described later with respect to FIG. 9, when the toilet bowl is washed, so that it is possible to prevent the precision instrument such as the water level sensor 38 from breaking down. .. In this case, the measuring means control unit 54 does not have to transmit the operating state of the urination information measuring device 5 to the information linking unit 52.

Further, the information cooperation unit 52 and the cleaning means control unit 405 are connected by a cable C1 by wire. The information cooperation unit 52 and the measuring means control unit 54 are connected by a cable C3 by wire. The toilet bowl cleaning control unit 53 and the toilet bowl cleaning means 61 are connected by a cable C2 by wire. In this way, by connecting the sanitary cleaning device 3 and the urination information measuring device 5 and the information linking unit 52 by wire, communication can be performed more reliably. However, in the embodiment, wireless communication may be used.

Further, in this example, the radio wave receiving unit 51, the information cooperation unit 52, and the toilet bowl cleaning control unit 53 are circuits provided separately on different substrates, and the substrate unit 50 is a single unit. Further, the substrate portion 50 is separate from the sanitary cleaning device 3 and the urination information measuring device 5, and is removable. However, at least a part of the radio wave receiving unit 51, the information cooperation unit 52, and the toilet bowl cleaning control unit 53 may be integrated on one substrate, or may be further divided on a plurality of substrates. Further, the radio wave receiving unit 51, the information cooperation unit 52, and the toilet bowl cleaning control unit 53 may be provided separately instead of being a single unit. For example, the toilet bowl unit 60 may include a toilet bowl cleaning control unit 53.

4 and 5 are perspective views illustrating a part of the biological information measuring device according to the embodiment in an exploded manner.
As shown in FIG. 4, the cabinet 18 has a front plate 18f (front surface). The front plate 18f has an opening 18a and a cover 18b that covers the opening 18a. FIG. 4 shows a state in which the cover 18b of the opening 18a is removed from the cabinet 18.

The cover 61c covers the toilet bowl cleaning means 61 and the recess 2c of the toilet bowl 2 from above. Further, the periphery of the rear portion of the cover 61c and the toilet bowl 2 is covered by the cabinet 18. As a result, even if water is discharged from the outer periphery of the cabinet 18 by the user's excretion or cleaning action, it is possible to prevent the toilet bowl cleaning means 61 from being splashed with water.
The cover 61c has a drain hole 61h that penetrates the cover 61c in the vertical direction. When the cover 61c is splashed with water, the water flows below the toilet bowl 2. Further, no electric component is provided below the drain hole 61h. As a result, high reliability can be maintained even if water should enter the cabinet 18.

As described above, the sanitary cleaning device 3 is removable from the toilet bowl 2. For example, the base plate BP shown in FIG. 6 can be used for attaching / detaching the sanitary cleaning device 3. As shown in FIG. 6, the fixing plate FP and the base plate BP are provided between the recess 2c and the bowl 22 on the upper surface of the toilet bowl 2. The base plate BP is fixed to the toilet bowl 2 by any means such as a bolt via the fixing plate FP. The position of the base plate BP is, for example, in front of the front plate of the cabinet 18.

When the sanitary cleaning device 3 is installed on the toilet bowl 2, the sanitary cleaning device 3 is placed on the rim 2r on the upper surface of the toilet bowl 2, and the sanitary cleaning device 3 is slid backward as shown by an arrow A1 shown in FIG. As a result, the unevenness provided on the base plate BP and the unevenness (not shown) provided on the lower surface of the sanitary cleaning device 3 are engaged with each other, and the sanitary cleaning device 3 is fixed to the toilet bowl 2. When the sanitary cleaning device 3 is removed from the toilet bowl 2, the sanitary cleaning device 3 is slid forward as shown by the arrow A2 shown in FIG.

As described with respect to FIGS. 4 and 5, the board portion 50 such as the information linking portion 52 is arranged on the back side of the front plate 18f of the cabinet 18. That is, the information cooperation unit 52 and the like are arranged at a position behind the toilet bowl 2 and close to the toilet bowl 2. As a result, even when the information cooperation unit 52 and the sanitary cleaning device 3 are connected by wire, the sanitary cleaning device 3 can be easily moved at the time of attachment / detachment. For example, when the sanitary cleaning device 3 is slid forward during cleaning, the cable is less likely to get in the way. For example, a cable for connecting to the substrate portion 50, a power supply cable, and a water supply cable are connected to the rear portion of the sanitary cleaning device 3.

It has a calibration pump 40, an on-off valve 42, and a manual ball valve 44. The on-off valve 42 is a solenoid valve that has a first on-off valve 42a, a second on-off valve 42b, a third on-off valve 42c, a fourth on-off valve 42d, and a fifth on-off valve 42e, each of which is operated by electric power. is there. The second on-off valve 42b, the third on-off valve 42c, the fourth on-off valve 42d, and the fifth on-off valve 42e are installed in the communication pipe 9 and open and close the flow path in the communication pipe 9. When the first on-off valve 42a is opened, water can be replenished from the water pipe to the refill tank 28. When the manual ball valve 44, the second on-off valve 42b, and the third on-off valve 42c are opened, the water level of the pooled water 21 in the bowl 22 and the water level in the water level measuring pipe 36 become the same. The water level sensor 38 measures the pressure of water (head pressure) in the water level measuring tube 36, converts the pressure into a voltage value according to the magnitude of the pressure, and outputs the pressure to the measuring means control unit 54.

The refill tank 28 is installed above the drain trap 32. When a certain amount of water is supplied into the refill tank 28, the water is discharged to the overflow pipe 32a of the drain trap 32. The water discharged to the overflow pipe 32a passes through the overflow pipe 32a and is supplied into the drain trap 32. The drain trap 32 communicates with the drain pipe 23 of the building provided on the downstream side of the trap portion 25 of the toilet bowl 2. When a certain amount of water is supplied into the drain trap 32, the water is discharged into the drain pipe 23.

The first float switch 29 is installed in the refill tank 28 and at the upper end of the refill tank 28. The second float switch 31 is installed in the refill tank 28 and below the first float switch 29. When the first float switch 29 detects water, the measuring means control unit 54 closes the first on-off valve 42a. When the second float switch 31 stops detecting water, the measuring means control unit 54 opens the first on-off valve 42a.

The installer of the biological information measuring device 1 can disconnect the toilet bowl 2 and the urination information measuring device 5 by operating the manual ball valve 44 in the closed state.

Next, a method of measuring urination information by the biological information measuring device 1 will be described.
It is assumed that the manual ball valve 44 is always in the open state.
In a state (standby state) in which the human body detecting means provided in the sanitary cleaning device does not detect a person entering the toilet room TR, the water level in the water level measuring tube 36 is the water level of the pool 21 in the bowl 22. It is higher than the measurement start water level A, which is the water level. For example, in the standby state, the inside of the water level measuring pipe 36 is substantially full. The measurement start water level A is higher than the rupture water level L and lower than the overflow water level H.

The measuring means control unit 54 opens the second on-off valve 42b and the third on-off valve 42c before receiving the measurement start signal described in detail later. For example, when the human body detecting means detects a person who has entered the toilet room TR, the measuring means control unit 54 opens the second on-off valve 42b and the third on-off valve 42c.

When the second on-off valve 42b and the third on-off valve 42c are opened, the water level in the water level measuring pipe 36 becomes the same as the water level of the pooled water 21 in the bowl 22. For example, one second after the second on-off valve 42b and the third on-off valve 42c are opened, the measuring means control unit 54 closes the second on-off valve 42b and the third on-off valve 42c.

For example, when a person entering the room holds a bar code tag held by the person entering the room on the bar code reading device 10, the bar code reading device 10 transmits a measurement start signal of urination information. In addition, for example, the bar code tag has a bar code that can read the personal data of the occupant himself / herself. When the measurement means control unit 54 receives the measurement start signal, for example, 10 minutes after the human body detecting means detects the occupant, the second on-off valve 42b and the third on-off valve 42c are opened again. If the measuring means control unit 54 does not receive the measurement start signal for, for example, 10 minutes after the human body detecting means detects the occupant, the urination information measuring device 5 returns to the standby state.

When the urination information measuring device 5 becomes measurable after receiving the measurement start signal, "Please urinate" is displayed on the liquid crystal screen provided on the remote controller 12. At this time, the occupant, that is, the subject, starts the urination operation by visually recognizing the characters "Please urinate" displayed on the liquid crystal screen.

When the subject's urination operation is completed, the water level of the pool water 21 in the bowl 22 rises from the measurement start water level A to the post-urination water level C. That is, the water level of the pooled water 21 in the bowl 22 and the water level of the water in the water level measuring tube 36 become the water level C after urination. The subject can instruct the measuring means control unit 54 to end the measurement by pressing the measurement end switch provided on the remote controller 12. Alternatively, the subject can instruct the measuring means control unit 54 to end the measurement by holding the barcode over the barcode reading device 10. Alternatively, the user can instruct the measuring means control unit 54 to end the measurement by pressing the toilet bowl cleaning switch 13a.

When the measuring means control unit 54 receives the measurement end signal, the water level sensor 38 outputs the voltage value measured by the water pressure of the water in the water level measuring tube 36 to the measuring means control unit 54 according to the instruction of the measuring means control unit 54. To do. The measuring means control unit 54 calculates the amount of rising water in the bowl 22, that is, the amount of urine of the subject, by applying the input voltage value to the previously calculated relational expression of the amount of water with respect to the water level of the bowl 22.

The measuring means control unit 54 not only determines the urination volume of the subject, but also, for example, the urination time (seconds), the maximum urination flow rate (mL / sec), the average urine flow rate (mL / sec), and the maximum urine flow rate arrival time ( Calculate urination information such as seconds) and hesitation time (seconds). The urination time is the time from the start of urine discharge into the bowl 22 to the end of urine discharge into the bowl 22. The maximum urine flow rate is a value when the urine volume per unit time, that is, the urine flow rate, which is the urination rate, is the maximum. The average urine flow rate is an average value of the urine flow rate. The time to reach the maximum urine flow rate is the time from the start of urination until the value of the urine flow rate reaches the value of the maximum urine flow rate. The hesitation time is the time from when "Please urinate" is displayed on the LCD screen until the start of urination.

When the calculation of the urination information by the measuring means control unit 54 is completed, the measuring means control unit 54 closes the second on-off valve 42b and the third on-off valve 42c. Then, the toilet bowl cleaning control unit 53 discharges water from the water pipe into the toilet bowl 2 through the rim water discharge hole 24 and the jet water discharge hole 26. As a result, the inside of the bowl 22 is washed by the siphon phenomenon described above.

When the discharge operation in the bowl 22 is completed, the water supply means (not shown) of the toilet bowl 2 supplies water for rough adjustment to the water level between the rupture water level L and the measurement start water level A by the water supply from the rim water discharge hole 24. carry out. Next, the measuring means control unit 54 opens the first on-off valve 42a, the second on-off valve 42b, and the fifth on-off valve 42e. Further, the measuring means control unit 54 drives the refill pump 30. The water level in the pool water 21 in the bowl 22 is set to the measurement start water level A by the water in the water replenishment tank 28 sent by the drive of the water replenishment pump 30. Next, the third on-off valve 42c is opened and the second on-off valve 42b is closed. The inside of the water level measuring pipe 36 is washed with the water in the refill tank 28 which is sent by driving the refill pump 30. In addition, the water in the water replenishment tank 28, which is sent by driving the water replenishment pump 30, fills the water level measuring pipe 36 with substantially full water. When the inside of the water level measuring pipe 36 is substantially full, the measuring means control unit 54 stops the drive of the refill pump 30. Further, the measuring means control unit 54 closes the first on-off valve 42a, the third on-off valve 42c, and the fifth on-off valve 42e. After that, the urination information measuring device 5 returns to the standby state.
