In addition, the signal regarding the operation state of the sanitary washing device 3 is information indicating whether the sanitary washing device 3 is performing local cleaning (for example, information indicating an open / closed state of an electromagnetic valve that controls the supply of cleaning water to the nozzles). Etc.). The signal relating to the operation state of the toilet bowl cleaning means 61 is information indicating whether the toilet bowl cleaning means 61 is performing toilet flushing (for example, information indicating the open / closed state of the toilet flushing valve that controls the supply of flush water to the bowl 22) Etc.).

  When the urination information is measured, if the sanitary washing device 3 and the toilet bowl cleaning means 61 are operated, the measurement accuracy may be lowered. For example, when the urine information measuring device 5 measures the amount of urine by changing the water level in the bowl 22, when the cleaning water is supplied into the bowl 22 by the sanitary washing device 3 or the toilet bowl cleaning means 61, the water level in the bowl 22 is measured. Changes depending on the washing water.

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

  By the way, in general sanitary washing apparatuses, a plurality of models having different functions have been developed. For example, if there is a concern about an infectious disease, a function of spraying hypochlorous water may be required, or a function emphasizing local cleaning may be required at a women's clinic. Therefore, it is desirable that various types of sanitary washing apparatuses can be installed also in the biological information measuring apparatus. On the other hand, in the conventional biological information measuring device, the sanitary washing device is integrated with the toilet bowl, and the function corresponding to the information link unit 52 is built in the sanitary washing device. Many sanitary washing apparatuses do not have a function corresponding to the information linkage unit 52, and are not configured so that the operation of the sanitary washing apparatus and the measurement of urination information can be linked in advance. Therefore, it has been difficult to install various types of sanitary washing devices in the biological information measuring device.

  On the other hand, the biological information measuring apparatus 1 according to the embodiment includes an information link unit 52 provided as a separate body from the sanitary washing apparatus 3 outside the outer shell (cover 3c) of the sanitary washing apparatus 3. Thereby, if the information cooperation part 52 and the washing | cleaning means control part 405 of the sanitary washing apparatus 3 are connected by a cable etc., operation | movement of a sanitary washing apparatus and measurement of urination information can be linked. For example, even a sanitary washing device that is not configured in advance so that the operation of the sanitary washing device and the measurement of urination information can be linked can be installed in the biological information measuring device. Therefore, various types of sanitary washing devices can be installed. Moreover, when the information cooperation part 52 fails, only the information cooperation part 52 should be replaced | exchanged and it is not necessary to replace the sanitary washing apparatus 3. FIG.

  Further, for example, the measurement means control unit 54 stops measuring the urination information when the local cleaning is started and when the toilet cleaning is started. Thus, in the biological information measuring apparatus 1 according to the embodiment, priority can be given to the function (toilet bowl washing or local washing) as a normal toilet. Thereby, usability can be improved. For example, even when the user forgets to press the measurement end switch of the remote controller 12 when measuring urination information, the measurement of urination information can be ended by operating the toilet flushing switch 13a. In addition, by stopping the measurement of urination information, it is possible to prevent water from being washed in the toilet bowl from flowing into a water level measuring tube 36, which will be described later with reference to FIG. 9, so that it is possible to prevent failure of precision instruments such as the water level sensor 38. . In this case, the measurement means control unit 54 does not have to transmit the operation state of the urination information measurement device 5 to the information cooperation unit 52.

  Moreover, the information cooperation part 52 and the washing | cleaning means control part 405 are connected with the cable by the cable C1. The information linkage unit 52 and the measurement means control unit 54 are connected by cable with a cable C3. The toilet bowl cleaning control unit 53 and the toilet bowl cleaning means 61 are connected to each other by a cable C2. Thus, communication can be performed more reliably by connecting the sanitary washing device 3 or the urination information measuring device 5 and the information link unit 52 by wire. However, in the embodiment, wireless communication may be used.

  In this example, the radio wave reception unit 51, the information cooperation unit 52, and the toilet bowl cleaning control unit 53 are circuits provided separately on different substrates, and are configured as one unit as the substrate unit 50. Moreover, the board | substrate part 50 is a different body from the sanitary washing apparatus 3 and the urination information measuring apparatus 5, and can be attached or detached. However, at least a part of the radio wave reception unit 51, the information linkage 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. In addition, the radio wave reception unit 51, the information cooperation unit 52, and the toilet bowl cleaning control unit 53 may be provided separately instead of as one unit. For example, the toilet unit 60 may include the toilet cleaning control unit 53.

When water is discharged from the jet water discharge hole 26, the trap portion 25 is filled with water. When the trap unit 25 is filled with water, a siphon phenomenon occurs in the trap unit 25. Due to this siphon phenomenon, a negative pressure is generated on the drain pipe 23 side. As a result, the accumulated water 21 in the bowl 22 is discharged to the drain pipe 23.

  The urination information measuring device 5 includes a refill tank 28, a first float switch 29, a second float switch 31, a refill water pump 30, a drain trap 32, an atmospheric pressure sensor 34, a water level measuring pipe 36, and a water level sensor 38. A calibration pump 40, an on-off valve 42, and a manual ball valve 44. The on-off valve 42 includes 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. 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. If the 1st on-off valve 42a is made into an open state, water can be replenished to the supplementary water tank 28 from a water pipe. 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 stored 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 (water head pressure) of the water in the water level measuring pipe 36, converts the pressure into a voltage value corresponding to the magnitude of the pressure, and outputs the voltage value to the measuring means control unit 54.

  The supplementary water tank 28 is installed above the drain trap 32. When a certain amount of water is supplied into the replenishing 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 downstream from 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 water tank 28 and at the upper end of the refill water 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 operator of the biological information measuring device 1 can release the connection between the toilet 2 and the urination information measuring device 5 by operating the manual ball valve 44 to the closed state.

Next, a method for measuring urination information by the biological information measuring apparatus 1 will be described.
Note that the manual ball valve 44 is always open.
In a state where the human body detecting means provided in the sanitary washing device does not detect a person entering the toilet room TR (standby state), the water level in the water level measuring pipe 36 is the water level of the stored water 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 water level measuring pipe 36 is substantially full. The measurement start water level A is higher than the breaking water level L and lower than the overflow water level H.

  The measurement means control unit 54 opens the second on-off valve 42b and the third on-off valve 42c before receiving a measurement start signal described in detail later. For example, when the human body detecting means detects a person entering 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 stored 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 measurement means controller 54 closes the second on-off valve 42b and the third on-off valve 42c.

  The bar code reader 10 transmits a measurement start signal of urination information when the room occupant puts, for example, a bar code tag held by the room occupant on the bar code reader 10. For example, the bar code tag includes a bar code that can read the personal data of the occupant. When the measurement means control unit 54 receives the measurement start signal, for example, for 10 minutes after the human body detection means detects the occupant, the second opening / closing valve 42b and the third opening / closing valve 42c are opened again. If, for example, the measurement means control unit 54 does not receive a measurement start signal for 10 minutes after the human body detection means detects a room occupant, the urination information measurement device 5 returns to the standby state.

  After the measurement start signal is received, when the urination information measuring device 5 becomes ready for measurement, “Please urinate” is displayed on the liquid crystal screen provided in 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 stored water 21 in the bowl 22 rises from the measurement start water level A to the post-urine water level C. That is, the water level of the stored water 21 in the bowl 22 and the water level in the water level measuring tube 36 become the post-urine water level C. The subject can instruct the measurement means control unit 54 to end the measurement by pressing a 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 placing the barcode on the barcode reader 10. Alternatively, the user can instruct the measurement means control unit 54 to end the measurement by pressing the toilet cleaning switch 13a.

  When the measurement 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 measurement pipe 36 to the measurement means control unit 54 according to an instruction from the measurement 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 urine volume of the subject by applying the input voltage value to the relational expression of the water amount with respect to the water level of the bowl 22 that has been calculated in advance.

  The measurement means control unit 54 not only determines the urine volume of the subject, but also includes, for example, urination time (seconds), maximum urine flow rate (mL / second), average urine flow rate (mL / second), and maximum urine flow rate arrival time ( Urination information such as seconds), hesitation time (seconds), and the like are calculated. The urination time is the time from the start of urine discharge into the bowl 22 to the end of the urine discharge into the bowl 22. The maximum urine flow rate is a value when the amount of urine per unit time, that is, the urine flow rate, which is a urination rate, is maximum. The average urine flow rate is an average value of the urine flow rate. The maximum urinary flow rate arrival time is the time from the start of urination until the urinary flow rate reaches the maximum urine flow rate. The hesitation time is the time from when “please urinate” is displayed on the LCD screen until urination starts.

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

  When the discharge operation in the bowl 22 is finished, the water supply means (not shown) of the toilet bowl 2 supplies the water for rough adjustment to the water level between the broken water level L and the measurement start water level A by water supply from the rim water discharge hole 24. carry out. Next, the measuring means controller 54 opens the first on-off valve 42a, the second on-off valve 42b, and the fifth on-off valve 42e. Further, the measurement means control unit 54 drives the water replenishment pump 30. The water level of the stored water 21 in the bowl 22 is set to the measurement start water level A by the water in the water replenishing tank 28 supplied by driving the water replenishing 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 water replenishing tank 28 that is fed by driving the water replenishing pump 30. Further, the water level measuring pipe 36 is substantially filled with water in the water replenishing tank 28 which is fed by driving the water replenishing pump 30. When the inside of the water level measuring pipe 36 is almost full, the measuring means control unit 54 stops the driving of the water replenishment pump 30. Further, the measurement means control unit 54 closes the first on-off valve 42a, the third on-off valve 42c, and the fifth on-off valve 42e. Thereafter, the urination information measuring device 5 returns to the standby state.
