Description

  The present invention relates to a biological information measuring toilet capable of measuring various biological information such as urination volume and urine volume rate of a subject using a Western-style toilet.

  As a conventional biological information measuring toilet, urine excreted in a bowl of a Western-style toilet is sucked into a predetermined container provided in a measurement unit, and its volume is measured and converted into various biological information such as urine volume. (For example, refer to Patent Document 1).

  On the other hand, the urine excreted in the Western-style toilet is not sucked into the measurement system, the fluctuation of the water level over time in the bowl of the toilet bowl is measured, and the urine volume and Some measure various biological information such as the urine volume rate (see, for example, Patent Document 2).

Japanese Patent Laid-Open No. 10-82783 International Publication No. 2004/113630 Pamphlet

  Both of the urine volume measuring device described in Patent Document 1 and the toilet unit described in Patent Document 2 increase the amount of accumulated water in the ball by the urine discharged in the ball and become the overflow water level of the toilet trap or more. Since the urine mixed water flows out to the sewage pipe connected to the trap and the measurement itself becomes impossible, the water level in the ball when starting the measurement (hereinafter this water level) Is called “measurement start water level”) at least for the measurement range from the overflow water level.

  However, since the urine volume measuring device described in Patent Document 1 is a method of forming the measurement start water level by discharging the stored water in the ball stored by the stored water supply after the previous use through the drain pipe, it is waiting for use. If the operation of discharging the stored water immediately from the state is performed, the stored water is discharged as it is even if foreign matter such as toilet paper is put into the stored water during cleaning work or the like. For this reason, if the foreign matter is caught in the middle of the discharge pipe, the pipe may be clogged and the measurement preparation operation cannot be performed, which may make measurement impossible.

  On the other hand, in the case of the toilet unit described in Patent Document 2, the formation of the measurement start water level is performed using a siphon phenomenon with a normal trap provided in the toilet as a discharge pipe, so that the foreign matter of the degree described above is clogged with piping, etc. The problem does not occur. However, advanced control for controlling the siphon phenomenon is required in order to form the measurement start water level at an accurate position only by the siphon phenomenon. In addition, a separate water supply system is required when forming the measurement start water level by supplying water after discharging due to siphon phenomenon.

  Furthermore, in the case of the urine volume measuring device described in Patent Document 1, it is included in the urine because the urine mixed water is moved to the measurement unit and the change in the water volume due to urination is measured when measuring. In order to avoid corrosion due to the electrolyte, it is necessary to provide corrosion resistance to the pipes, containers, on-off valves, pumps, etc. constituting the measurement pipe. In addition, when stool is excreted during measurement, the piping system may be clogged with solid matter mixed in the stored water.

  A problem to be solved by the present invention is a biological information measuring toilet that does not suck solid matter that causes clogging of a pipe line into a measurement system and can perform highly accurate biological information measurement with a simple structure. Is to provide.

The biological information measuring toilet of the present invention,
A ball that receives a user's urine, a discharge pipe that communicates the ball with the sewage pipe and discharges the contents of the ball to the sewage pipe, and configures the discharge pipe and seals the communication with the sewage pipe. A trap for storing water, a water supply means for forming the water in the ball, and discharging the water to form the water level at a predetermined level lower than the overflow water level of the trap. In a biological information measuring toilet comprising: a water level forming means; and a biological information measuring means for measuring biological information by measuring an increase in the amount of the accumulated water due to excretion performed by a subject from the predetermined water level,
The water level forming means includes a reservoir drainage pipe having one end as an inlet opening at a position below the predetermined water level of the ball and the other end communicating with the outside of the ball, and via the reservoir drainage pipe. Water storage means for moving the water storage out of the ball,
The operation of forming the predetermined water level is performed by performing a stored water supply operation by the stored water supply unit after cleaning the ball and discharging the contents, and operating the stored water moving unit after the stored water supply operation is completed. It is characterized by performing.

  With such a configuration, the clean stored water supplied into the trap by the stored water supply operation performed after the cleaning of the ball and the discharge of the contents is immediately discharged through the stored water drain pipe. It is possible to set the measurement start water level, and solid matter that causes clogging of the pipe is not sucked into the measurement system, so clogging with solids in the stored water drain pipe for setting the measurement start water level is not possible. It becomes difficult to occur. In addition, it is possible to accurately set the measurement start water level at a predetermined water level lower than the overflow water level by simply moving the water discharged from the inlet to the outside of the ball via the water drainage pipe. High-precision biological information measurement can be performed with a simple structure.

  Here, the operation of forming the predetermined water level can be performed after the measurement operation is completed. With such a configuration, the water level after the previous user finishes urination and the measurement operation is finished is a predetermined water level necessary for starting measurement. Biological information measurement can be started immediately using the measuring toilet. Since the predetermined time can be appropriately set according to the use conditions, the stored water is discharged continuously after the supply of the flush water for toilet flushing, or after a short time after the supply of the stored water. Water can be discharged.

  Further, the biological information measuring means can perform the measurement in a state where the accumulated water is retained in the ball. With such a configuration, during measurement of biological information, it is possible to measure while retaining in the ball without moving the accumulated water mixed with excrement in the ball in the measurement pipe. No problems such as corrosion in the measurement pipeline or clogging of the pipeline due to movement of components other than the stored water.

  Here, a stored water storage means for storing the stored water moved from within the ball by the stored water moving means is provided, the other end of the stored water drain pipe has an outlet opening in the ball, After the measurement is completed, the stored water stored in the stored water storage means can be allowed to flow out into the toilet bowl from the outlet. With such a configuration, wasteful discharge of water can be suppressed, and a water saving effect can be obtained.

  On the other hand, the other end of the stored water drain pipe has an outlet opening to a discharge pipe communicating from the ball to the sewage pipe, and the stored water flowing out of the ball from the inlet is discharged into the sewage pipe. It can also be discharged. With such a configuration, the stored water is immediately discharged to the sewage pipe without being stored, and the stored water that is highly likely to be contaminated with microorganisms or the like in the excreta may stay in the stored water drain pipe. Therefore, infectious contamination is less likely to occur in the apparatus, and maintenance work can be performed hygienically.

  Here, if the stored water drain pipe and the outlet are arranged at a position lower than the predetermined water level, the stored water discharged from the outlet can be naturally discharged by the action of gravity, so that a measurement start water level is formed. Therefore, it is only necessary to install an on-off valve for opening and closing the pipe. Therefore, a special configuration such as a pump is not required, and the device configuration is simplified, so that the device cost is reduced.

  Further, if the foreign matter removing means for removing the foreign matter in the stored water is provided in the stored water drain pipe, it is possible to prevent the measurement path from being clogged by the foreign matter in the stored water sucked from the inlet.

  Furthermore, the predetermined water level forming operation may be stopped when a person approaching the toilet is detected during the predetermined water level forming operation. With this configuration, while draining the water in the ball from the inlet to the water drainage pipe, not only those related to the user's measurement, but also throwing dust into the water. Even if it receives mischievous treatment or solid matter is excreted into the ball, it is possible to prevent clogging of the inlet and the measurement path to the stored water drainage pipe due to the solid matter.

  The operation of the stored water moving means can be stopped when the turbidity of the stored water in the ball exceeds a threshold value. In such a configuration, while the accumulated water in the ball is being discharged from the inflow port to the accumulated water drain pipe, the solids caused by the foreign matter thrown into the ball or the turbidity of the accumulated water It is possible to prevent clogging of the inlet to the stored water drain pipe and the stored water drain pipe.

  In this case, after the turbidity of the stored water in the ball exceeds a threshold value and the operation of the stored water moving unit is stopped, it is desirable that the stored water supply unit performs toilet cleaning. With such a configuration, after the sewage in the ball is discharged, clean water can be stored again, so that the water discharged to set the measurement start water level is discharged to the water storage drain line. In addition to preventing clogging of the inlet and the stored water drain pipe, it is possible to avoid a decrease in biometric information measurement accuracy due to dirt accumulation in the measurement pipe system and the like.

  According to the present invention, it is possible to provide a biological information measuring toilet capable of performing highly accurate biological information measurement with a simple structure without sucking excrement causing a blockage in a measurement system.

  Hereinafter, a first embodiment of the present invention will be described based on the drawings. FIG. 1 is a perspective view showing a biological information measuring toilet according to the first embodiment of the present invention, FIG. 2 is a system block diagram of the biological information measuring toilet shown in FIG. 1, and FIG. 3 is one of the biological information measuring toilets shown in FIG. FIG.

  As shown in FIG. 1, the biological information measuring toilet 10 of this embodiment includes a Western-style toilet 11 that receives a user's excrement and discharges it to a sewage pipe 35, and urine information measuring means that is one of biological information measuring means. 12, a cabinet 14 in which the control means 13 and the like are built in, and an operation / display unit 20 disposed on a side wall surface of the western-style toilet 11. The western toilet 11 includes a toilet seat 15 on which a user is seated, a toilet lid 17 that covers the ball 16 and the toilet seat 15 so as to be openable and closable, and a urine collection unit 18 having a urine collection device 18a and a urine collection arm 18b. The operation / display unit 20 includes a remote controller 19 for operating a sanitary washing device 23 provided in the western-style toilet 11, a remote controller 21 for causing the urination information measuring means 12 to function, and a printer 22 for printing a biological information measurement result. And.

  As shown in FIG. 2, the urination information measuring means 12 is provided with a water level measuring means 31 and a stored water moving means 32. The control means 13 is provided with a calibration curve storage means 38, a biological information calculation means 39 and an information storage means 40. Note that the urine collection unit 18 for collecting a part of excreted urine for component analysis and the sanitary washing device 23 for washing the local part are not essential requirements for constituting the biological information measuring toilet of the present invention.

  As shown in FIG. 3, the western toilet 11 includes a ball 16 that receives a user's urine, a rim water discharge nozzle 24 a and a jet water discharge nozzle 24 b that supply cleaning water into the ball 16, a ball 16, and a sewage pipe 35. A drain socket 9 that communicates with each other, and a trap 25 that stores the stored water W1 that seals the sewage pipe 35 are provided. In the water channel switching means 4 disposed downstream of the water stop cock 3, the water is branched into a water supply line 24L to the rim water discharge nozzle 24a and a water supply line 24J to the jet water discharge nozzle 24b.

  Further, a connecting line 27 is piped from the branching part 26 provided in the middle of the water supply line 24J to the jet water discharge nozzle 24b toward the urine information measuring means 12. The communication conduit 27 communicates with the stored water moving means 32 and the water level measuring means 31 through the foreign matter removing means 29 from the jet water discharge nozzle 24b. An open / close valve 28 that opens and closes the connecting conduit 27 is disposed between the stored water moving means 32 and the water level measuring means 31. In this embodiment, the foreign matter removing means 29 is a strainer, the water level measuring means 31 is a pressure sensor, and the stored water moving means 32 is a positive displacement pump, but is not limited thereto.

  The stored water moving means 32 is supplied from the jet water discharging nozzle 24b serving as an inlet to the stored water drain pipe after the rim water discharging nozzle 24a serving as the stored water supplying means performed at the time of flushing the toilet bowl. It has a function of setting the water level to a measurement start water level W1L lower than the overflow water level H by sucking a certain amount of the stored water W1 through the connecting pipe 27 as a water drainage pipe. . After setting to the measurement start water level W1L by the stored water moving means 32, the on-off valve 28 is opened, and the communication line 27 between the stored water W1 and the water level measuring means 31 is communicated as a measurement line.

  The water level measuring means 31 has a function of measuring the water pressure of the stored water W1 via the connecting conduit 27 communicating with the stored water W1 in the ball 16. When the user urinates to the ball 16, the water level of the stored water W1 rises above the measurement start water level W1L, and the water pressure change at that time is measured by the water level measuring means 31. Based on the measurement value obtained by the water level measurement means 31 and the record data stored in the calibration curve storage means 38 in advance, the biological information calculation means 39 calculates various biological information such as the amount of urination and the urine volume rate. The information is recorded in the information storage means 40 and the measurement result is displayed on the operation / display unit 20.

  Here, the operation of the biological information measuring toilet 10 will be described with reference to FIGS. 3, 4 and 5. FIG. 4 is a timing chart of normal operation of the biological information measuring toilet shown in FIG. 1, and FIG. 5 is a timing chart when entering the room during preparation in the biological information measuring toilet shown in FIG.

  In the biological information measuring toilet 10 in the standby state, the water level of the stored water W1 in the ball 11 has already been set to the measurement start water level W1L lower than the overflow water level H as shown in FIG. This is because the stored water moving means 32 operates after the stored water supply by the stored water supply means performed at the time of toilet cleaning by the previous user's cleaning operation, and the stored water in the balls 16 passes through the jet water discharge nozzle 24b. This is because the water level is lowered to the measurement start water level W1L lower than the overflow water level H by sucking a certain amount from W1.

  When the user enters the toilet in which the biological information measuring toilet 10 is placed and performs a preparation operation on the remote controller 21, a display indicating that preparation is in progress is made and the urination information measuring means 12 is activated. When the measurement preparation is completed, a preparation completion notification is displayed on the remote controller 21, so the user undresses and sits on the toilet seat 15 and urinates toward the ball 16. In this case, the male may urinate in a standing posture. When the user's urine flows into the stored water W1, the water level rises above the measurement start water level W1L, and the water pressure of the stored water W1 changes, so that the amount of change passes through the jet water discharge nozzle 24b and the connecting conduit 27. It is measured by the water level measuring means 31 communicating with the stored water W1 in the ball 16. Then, based on the measurement value obtained by the water level measurement means 31 and the record data stored in the calibration curve storage means 38 in advance, the biological information calculation means 39 calculates various biological information such as urine output and urine volume rate. The information is stored in the information storage means 40.

  When urination is completed and the user performs a predetermined end operation on the remote controller 21, biological information measurement values such as urine volume and urine volume rate are displayed on the display unit of the remote controller 21. Thereafter, when a predetermined output operation is performed on the remote controller 21, a piece of paper on which a biological information measurement value such as urine volume is printed is output from the printer 22. The information storage means 40 is not limited to this embodiment, but uses an ID card, a semiconductor memory, or a server connected via a hospital LAN such as a hospital where the biological information measuring toilet 10 is installed. be able to.

  When the user performs a toilet cleaning operation after urination is finished, water is supplied from the rim water discharge nozzle 24 a and water is supplied from the jet water discharge nozzle 24 b to clean the surface of the ball 16 and to mix urine in the ball 16 and the trap 25. Is discharged to the sewage pipe 35 of the stored water W1. Thereafter, water is supplied again from the rim water spouting nozzle 24a serving as the stored water supply means into the ball 16 for a certain period of time, whereby the stored water W1 up to the overflow water level H is stored in the ball 16.

  When supply of stored water at the time of toilet flushing is finished and the water level of the stored water W1 reaches the overflow water level H, when a predetermined time has elapsed, the positive displacement pump as the stored water moving means 32 operates for a certain period of time, and the jet water discharge nozzle 24b Since a fixed amount is sucked from the stored water W1 in the ball 16 via the connecting line 27 and stored in the closed tank 32a constituting the positive displacement pump, the water level is measured lower than the overflow water level H. The start water level W1L is set, and a normal standby state is set. Since such a series of operations are automatically performed, the user can leave the toilet freely after performing the toilet cleaning operation. At this time, the connecting pipe 27 functions as a stored water drain pipe, and the jet water discharge nozzle 24b functions as an inlet of stored water to the stored water drain pipe.

  As described above, in the biological information measuring toilet 10, the measurement start water level W1L is set by sucking the clean water W1 stored in the trap 25 after the water supply performed at the time of toilet cleaning, so the measurement start water level It is difficult for the communication pipe 27 for setting W1L to be clogged. Further, the stored water W1 sucked from the jet water discharge nozzle 24b serving as an inlet of the stored water W1 to the stored water drain pipe is simply moved out of the ball 16 via the connecting pipe 27 by the stored water moving means 32. Thus, since the measurement start water level W1L can be set at a position lower than the overflow water level H, the urination information measuring means 12 has a simple configuration. Further, in the present embodiment, the positive displacement pump employed as the stored water moving means 32 can suck an accurate amount of water, so that the position reproducibility of the measurement start water level W1L is high. Information measurement can be performed. In addition, when so high accuracy is not required, it is also possible to use a normal suction pump instead of the positive displacement pump. In that case, it is necessary to separately provide a storage tank in place of the sealed tank 32a in order to store the sucked stored water.

  Further, in the biological information measurement toilet 10, since the suction by the stored water moving means 32 is performed immediately after the toilet cleaning is completed, the next user can quickly use the biological information measurement toilet 10 in the standby state. Information measurement can be started. In this case, after the toilet cleaning is completed, the time until the suction by the stored water moving means 32 is started can be appropriately set according to the use conditions, and therefore the suction is performed continuously after the toilet cleaning. Or, after the toilet bowl is washed, the suction can be performed after some time.

Further, by disposing the foreign matter removing means 29 in the middle of the connecting pipe line 27, the foreign matter in the stored water W1 sucked from the inflow port (jet water discharge nozzle 24b) to the stored water drain pipe line is removed by this foreign matter removing means. Since it is removed at 29, the clogging of the connecting pipe line 27 can be prevented.
Further, as shown in FIG. 3, a positive displacement pump is used as the stored water moving means 32 for discharging a part of the stored water W1 after toilet flushing, and the stored water W1 is sucked into the sealed tank 32a. Therefore, the amount of sucked water is stable, the position reproducibility of the measurement start water level W1L is high, and as a result, highly accurate biological information measurement can be performed.

  Further, the stored water sucked and stored in the sealed tank 32a is discharged into the ball 16 from the jet water discharge nozzle 24b by causing the connecting pipe 27 to flow backward after the measurement is completed. Therefore, at this time, the sealed tank 32a functions as a stored water storage means, and the water discharge nozzle 24b functions as a stored water outlet from the stored water drain pipe. In addition, when returning the water stored in the sealed tank 32a to the ball 16, it is vigorously returned by a positive displacement pump when the toilet bowl is washed, and water is supplied to the trap 25 together with the rim water discharge to promote the occurrence of the siphon phenomenon. Or, water can be discharged immediately before the siphon runs out, and the continuation of the siphon phenomenon can be promoted.

  Next, based on FIG. 5, the operation when entering the room during the preparation operation of the biological information measuring toilet 10 will be described. As shown in FIG. 5, after the previous user leaves the toilet, the toilet cleaning is finished, and when the stored water W1 is sucked by the stored water moving means 32 (under preparation), the next use is performed. When a person enters the toilet, when the human body detecting means (not shown) detects the entry, the stored water moving means 32 (positive displacement pump) stops immediately. Then, after water is supplied from the rim water discharge nozzle 24a and the jet water discharge nozzle 24b and normal toilet flushing is performed, water supply from the rim water discharge nozzle 24a and suction of the stored water W1 by the stored water moving means 32 are performed, and measurement is started. Water level W1L is set. When the user performs a preparatory operation in these processes, since the preparation completion notification is performed after the setting of the measurement start water level W1L is completed, the biological information measurement can be performed through the same process as described above.

  As described above, in the biological information measuring toilet 10, when the stored water W1 is sucked by the stored water moving means 32 (in preparation) and the next user enters the toilet, the toilet paper is mistakenly entered. Such a case is also assumed that the water is poured into the stored water W1. Even in such a case, the stored water moving means 32 (the positive displacement pump) immediately stops so as not to suck the solid matter. Then, after cleaning the ball 16 and discharging the contents again, a stored water supply operation for supplying the stored water is performed to suck the supplied stored water. For this reason, the solid water discharged into the ball 16 while sucking the stored water W1 in the ball 16 causes the jet water discharge nozzle 24b and the connecting conduit 27 to be an inlet to the stored water drainage pipe. Can be prevented from clogging.

  Next, based on FIG. 6 and FIG. 7, the second embodiment of the present invention suitable for a case where a biological information measuring toilet is configured using a Western-style toilet whose method of cleaning the toilet is different from the Western-style toilet 11 described above. The operation will be described. Since the configuration other than the western toilet 11 is the same as that of the first embodiment, the description thereof is omitted, and only the operation thereof will be described here. FIG. 6 is a timing chart of normal operation of the biological information measuring toilet according to the second embodiment, and FIG. 7 is a timing chart when entering the room during preparation in the biological information measuring toilet according to the second embodiment.

  The present embodiment assumes a case where a biological information measuring toilet is configured using a Western-style toilet that uses a swirling flow to discharge cleaning and filth during a toilet cleaning operation. In this method, cleaning water is spouted in a direction substantially tangential to the outer circumference of the ball to increase the cleaning power of the inner surface of the ball. However, if the water discharging time is too long, all excrement tends to gather in the center of the water reservoir. On the other hand, in the biological information measuring toilet of the present invention, the water level at the time of measurement is set lower than the overflow water level, so that the siphon phenomenon in the waste discharging process during the toilet cleaning operation performed after the measurement is stabilized. In order to generate them automatically, a process for raising the level of the stored water must be carried out before that. If this process is incorporated as a pre-process of the toilet bowl cleaning process and the rim water supply time is lengthened, as described above, the excrement that has solidified in the center of the stored water will be splashed in the toilet bowl even after discharge due to the siphon phenomenon. May leave a little. Therefore, this cleaning method takes into consideration the phenomenon that excrement collects in the center of the accumulated water.

  In the case of the present embodiment, as shown in FIG. 6, the process until the user enters the room, urinates, and performs a predetermined end operation on the remote controller 21 is the same as that of the biological information measuring toilet 10 described above. However, in the biological information measuring toilet 10, in order to measure the change in the stored water level accompanying urination, the stored water level that should generally be the overflow water level H is lowered to the measurement start water level W1L. Since the amount of stored water is smaller than that of the general Western-style toilet 11, as shown in FIG. 6, when the user performs a predetermined end operation on the remote controller 21, biological information such as urine volume and urine volume rate In parallel with the display of the measurement value on the display unit of the remote controller 21, water is supplied from the rim water spouting nozzle to the ball, and the accumulated water in the ball is condensed to the overflow water level. Thereafter, when the user performs the toilet cleaning operation, the toilet cleaning and the measurement start water level are set in the same manner as in the biological information measuring toilet 10.

  Further, in this embodiment, when entering the room during preparation, as shown in FIG. 7, it is the same as the above-described biological information measuring toilet 10 until the stored water moving means 32 (the positive displacement pump) immediately stops. However, immediately after the stop, the toilet bowl is washed after the water is supplied from the rim water spouting nozzle until the water accumulated in the ball condenses to the overflow water level. Similarly to the case of FIG. 6, when the user performs a predetermined end operation on the remote controller 21, the biological information measurement values such as the urine volume and the urine volume rate are displayed on the display unit of the remote controller 21. Then, water is supplied from the rim water spouting nozzle to the ball, and the accumulated water in the ball is condensed to the overflow water level.

  As described above, the biological information measuring toilet of the present invention can also be configured using a swirl flow type Western toilet, and obtains the same functions and effects as those configured using the normal Western toilet 11. be able to.

  Next, the third and fourth embodiments of the present invention will be described with reference to FIGS. FIG. 8 is a partially omitted cross-sectional view of a biological information measuring toilet according to the third embodiment of the present invention, FIG. 9 is a system block diagram of the biological information measuring toilet according to the fourth embodiment of the present invention, and FIG. FIG. 11 is a partially omitted cross-sectional view of a biological information measuring toilet according to a fifth embodiment of the present invention. 8 to 11, parts having the same structure and function as the constituent parts of the biological information measuring toilet 10 shown in FIGS. 1 to 3 are denoted by the same reference numerals as those in FIGS.

  In the biological information measuring toilet 50 shown in FIG. 8, a measurement pipe 52 having an upper end opened to the atmosphere is connected to an open / close valve 51 to form a sealed tank 32a that constitutes a stored water moving means 32 (a positive displacement pump). It is communicated to. When the on-off valve 51 is opened, the water level of the stored water W1 in the ball 16 and the water level in the measuring tube 52 become the same. That is, the flushed water W1 after toilet flushing is awaited by waiting in the sealed tank 32a constituting the accumulated water moving means 32 (positive displacement pump), and the pipe to the measurement tube 52 is also opened when measuring biological information. Then, the water level change of the stored water W1 in the ball 16 after urination is measured by measuring the change in the stored water level with the water level measuring means 31 (pressure sensor), and biological information such as urine volume and urine volume rate is measured. Measure.

  In the case where the connecting pipe 27 serving as a measurement path communicating between the stored water W1 and the water level measuring means 31 is configured as a sealed pipe as in the above-described embodiment, the water level of the stored water W1 accompanying urination is Then, it is transmitted to the water level measuring means 31 as a change in the stored water level as it is. However, as in this embodiment, if the connection pipe 27 serving as the measurement path is connected to the measurement pipe 52 that is an open pipe, the water level fluctuation force due to the ripple of the water level of the stored water W1 is released. Since it will be escaped by the measuring tube 52, the pulsation of the measured water level fluctuation will be suppressed. In particular, the ripple of the water level of the stored water W1 after the end of urination has the technical effect of being controlled in a short time.

  Next, based on FIG. 9, FIG. 10, 4th embodiment of this invention is described. The configuration of the biological information measuring toilet 60 of the present embodiment is as shown in FIG. 9, and the other end of the stored water drainage pipe having the inflow port (jet water discharge nozzle 24 b) in the ball 16 is connected to the Western-style toilet through the drain trap 63. 11 is connected to the discharge pipe (drain socket 9), and the water discharged from the ball 16 is immediately discharged to the sewer pipe. The configuration of the stored water drain pipe is different from that of the first and second embodiments described above, and the other configurations are the same.

  In the biological information measuring toilet 60 shown in FIGS. 9 and 10, a drainage path 61 branched from the connecting pipe 27 on the upstream side of the opening / closing valve 28 and communicating with the opening 64 of the drainage socket 9 is provided. A pump P and a drain trap 63 functioning as the stored water moving means 32 are provided in the middle of the process. When the open / close valve 62 is opened, the stored water W1 after the toilet bowl cleaning is sucked by the stored water moving means 32 (pump P) communicating with the communication line 27, and the stored water from the stored water drain line is discharged via the drain path 61. The measurement start water level W1L is set by discharging into the discharge pipe line (in the drainage socket 9) from an opening 64 provided in the drainage socket 9 as an outlet through which water flows out.

  After the measurement start water level W1L is set, the drainage path 61 is closed when the on-off valve 62 is closed. Therefore, by measuring the water pressure change in the communication line 27 due to urination with the water level measuring means (pressure sensor) 31, The water level change of the stored water W1 in the ball 16 is measured, and biological information such as urine volume and urine volume rate is measured. In this way, if the sucked water is directly discharged to the discharge pipe, there is no part where the water that is highly likely to be contaminated by microorganisms in the excrement remains in the measurement path. There is a technical effect that infectious contamination is less likely to occur.

  Next, a fifth embodiment of the present invention will be described based on FIG. As shown in FIG. 11, the biological information measuring toilet 70 is provided with a drainage path 71 that branches from the connection pipe 27 and communicates with the inside of the drainage socket 9, and a pump as the stored water moving means 32 in the middle of the drainage path 71. The point which comprises P and the drain trap 73 and comprises the stored water drain pipe is the same as the biological information measuring toilet 60 of 4th embodiment mentioned above. However, a difference is that a calibration pipe 75 branched from the connecting pipe 27 on the upstream side of the on-off valve 28 and having an upper end opened to the atmosphere is provided, and an on-off valve 77 is provided in the middle of the calibration pipe 75. .

  In the case of the biological information measuring toilet 70 of the present embodiment, the on-off valve 28, the on-off valve 72, the on-off valve 77, and the on-off valve 76 are closed when the toilet bowl is washed. After cleaning the toilet bowl, after the stored water W1 becomes clean, the on-off valve 76 and the on-off valve 77 are first opened, and the stored water W1 is supplied to the calibration tube 75 to fill up and overflow.

  Next, the on-off valve 77 is closed, the on-off valve 76 and the on-off valve 72 are opened, and then the stored water W1 after toilet flushing is sucked by the pump P communicating with the communication pipe 27 and opened through the drainage path 71. By setting the measurement start water level W1L by discharging from the portion 74 into the drain socket 9, the pump P is stopped and the on-off valve 72 is closed.

  When measuring, the output of the water level measuring means (pressure sensor) 31 is calibrated in advance. Specifically, with the on-off valve 76 and the on-off valve 72 closed, the on-off valve 77 and the on-off valve 28 are opened, and the pressure associated with the water level in the calibration tube 75 is applied to the water level measuring means (pressure sensor) 31. . At this time, since the height of the calibration tube 75 is physically constant, the water level measuring means (pressure sensor) 31 is calibrated in absolute value.

  Next, the opening / closing valve 76 is opened, and the change in the water pressure in the ball 16 from the start of urination to the end of urination is measured by measuring the change in water pressure in the communication line 27 with the water level measuring means (pressure sensor) 31. Measure biometric information such as urine volume and urine volume rate. The overflow water level of the calibration tube 75 is set at a position lower than the overflow water level H of the trap 25 and higher than the measurement start water level W1L, and overflows from the calibration tube 75 due to a change in the water level of the stored water W1 accompanying urination. There is nothing. By adopting such a configuration, it is possible to achieve both the damping effect of the stored water pulsation by the calibration pipe 76 opened to the atmosphere and the improvement of the stored water level measurement accuracy by the absolute calibration of the water level measuring means (pressure sensor) 31. The technical effect that can be achieved.

  In each of the embodiments described above, the rim water discharge nozzle 24a has a function as a stored water supply means, and the stored water supply operation is incorporated into a series of toilet flushing operations during normal toilet flushing. One of the main points of the invention is that clean water supplied after the operation of cleaning the ball and discharging the contents is drained out of the ball to form a measurement start water level. Therefore, the toilet bowl cleaning operation may be configured to perform only the cleaning operation of the ball and the discharge of the contents, and the stored water supply operation may be performed independently after the toilet bowl cleaning operation is completed. Moreover, it is good also as a structure which gave the function as a stored water supply means not to the rim water spouting nozzle 24a but to the water outlet provided separately.

  Furthermore, in each of the embodiments described above, after the measurement of the biological information is completed, a predetermined water level that is the measurement start water level is formed and the standby state is set. The forming operation may not be performed after the measurement, but may be configured such that the overflow water level is set in the standby state and the predetermined water level is formed before the measurement is started. With such a configuration, when the biological information measuring toilet of the present invention is used for measuring biological information, the measurement preparation operation requires some time, but when used as a normal toilet, the overflow water level is maintained. Since the water storage surface in the ball is wide and the water storage depth is deep, the effect that the possibility of feces adhering to the toilet bowl surface is reduced can be expected.

  The biological information measuring toilet of the present invention can be widely used in toilets of hospitals and general households that require measurement of biological information such as urine volume and urine volume rate.
