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, there is one that uses a Western-style toilet and measures biological information such as the amount of urine by measuring a change in the stored water level due to excretion excreted in the ball. In such a biological information measuring toilet, since it is necessary to store in the ball the increased amount of accumulated water due to excreted excrement, the water level in the ball is determined in advance by the toilet used. The measurement is started after being lowered to a water level at which measurement starts below the water level (hereinafter referred to as measurement start water level) (see, for example, Patent Documents 1, 2, and 3).

  That is, in the case of the urine volume measuring device described in Patent Literatures 1 and 2, the measurement start water level is formed by discharging the stored water stored in the ball to the outside of the ball through a specially provided drainage port.

  On the other hand, in the case of the urine volume measuring device described in Patent Document 3, the stored water stored in the ball is discharged into the sewage pipe using the siphon phenomenon, and then supplied to the ball to adjust the level of the stored water. The measurement start water level is set.

Japanese Patent Laid-Open No. 10-94537 Japanese Patent Laid-Open No. 10-82783 International Publication No. 2004/13630 Pamphlet

  In the case of a biometric measuring toilet that measures the water level change due to excrement after forming the water level in the bowl of the western toilet bowl at the measurement start water level, the water level used to measure the water level change is measured. The range must be within the water level range (hereinafter referred to as the “reserved water level setting allowable range”) that ensures the function and operation of the toilet as a normal toilet. However, the allowable range for setting the stored water level is determined in relation to the type of toilet used as described below.

  First, the upper limit of the allowable water level setting range (hereinafter referred to as the “maximum set water level”) is the water level during defecation standby (hereinafter referred to as “defecation standby water level”), excluding the temporary high water level during toilet flushing. It is said.) This defecation standby water level is determined in consideration of the mutually contradictory phenomena related to the accumulated water level, such as the bouncing of the accumulated water due to defecation and the stool adhering to the ball surface, so the optimum setting position is the type of toilet bowl from the top of the toilet rim It is limited to the position of the fixed distance corresponding to.

  However, in the case of a normal Western-style toilet, the height at which a user with a general physique can easily sit or stand up is limited to a certain range, so the floor surface to the upper surface of the toilet rim There is an upper limit to the height. Therefore, the maximum set water level that is limited to the optimum distance from the upper surface of the toilet rim has an upper limit on the position from the installation floor surface in relation to the toilet used.

  On the other hand, the minimum set water level also has a lower limit position associated with the toilet used. That is, since it is necessary to provide a structure such as a drainage channel for excrement to pass under the bottom of the ball bottom of a normal Western-style toilet, there is a lower limit on the distance from the installation floor of the ball bottom. For this reason, when the measurement is started in a state where the ball is empty, the position of the bottom surface of the ball becomes the minimum set water level. In consideration of the possibility of excretion of stool at the time of biometric information measurement, in the case of a device configuration in which measurement is started from a state in which the stored water is stored in the ball, the optimal stored water from the bottom of the ball The position above by the depth of is the minimum set water level.

  As described above, since the maximum set water level and the minimum set water level are associated with the toilet and their positions are limited, the allowable level of the stored water level setting is determined according to the type of toilet actually used. Become. And depending on the combination of the type of toilet bowl to be used and the type of excrement to be measured, the amount of accumulated water corresponding to the above-described allowable range of the accumulated water level setting may not have much room for the maximum amount of excretion of the user. . In such a case, in order to maximize the measurement range actually used for the measurement for the toilet used, the water level range used for the measurement may be made to coincide with the above-mentioned allowable water level setting allowable range. However, the water level at the end of measurement, which is the upper limit of the water level during measurement, is determined by the amount of excretion of the subject and cannot be controlled on the device side. For this reason, it is necessary to set the water level at which the measurement that becomes the lower limit of the water level at the time of measurement (hereinafter referred to as “measurement start water level”) is as close as possible to the minimum set water level.

  However, as in the urine volume measuring device described in Patent Documents 1 and 2, in the urine volume measuring device configured to discharge the accumulated water from the drain port to form the measurement start water level, the amount of the accumulated water discharged from the drain port When the operation to set the measurement start water level to the predetermined water level is controlled, there are various variability factors such as the ball size of the Western-style toilet and the drainage capacity of the pump used. By simply controlling the operation, it is inevitable that a water level formation error, which is a difference between a predetermined predetermined water level and a measurement starting water level that is actually formed, is generated.

  On the other hand, in the case of the toilet unit described in Patent Document 3, there are various variation factors such as the ball size of the Western style toilet, the water supply pressure at the construction site, and the operation speed of the water supply valve, and the occurrence of the same water level formation error is avoided. I can't.

  Therefore, in any of the drainage and feed water type devices described in Patent Documents 1 to 3 described above, when the control condition is set with the target water level of the operation for forming the measurement start water level as the minimum set water level, The actually formed measurement start water level is shifted by at least the water level formation error, but depending on the amount, there is a possibility that the function / operation required for the toilet may be defective due to the above-described reason. Further, when the measurement start water level is shifted upward, there is a further problem that the range that can actually be measured is narrowed by the shift.

  Moreover, when the toilet bowl to be used is a trap type toilet bowl, another problem is added to the control of the measurement start water level forming operation. In other words, in trap-type toilets, the phenomenon of “out of seal” occurs when the stored water surface falls due to movement due to pressure fluctuations that occur in the sewage pipes communicating with the trap, and the trap mouth is exposed from the water surface. May occur. Therefore, in order to prevent the occurrence of this “out of sealed water”, the Building Standard Law requires that the depth of water accumulated from the upper end of the trap opening (hereinafter, (Referred to as “sealing depth”). Therefore, when using a trap-type toilet and waiting for use at the measurement start water level, a position 50 mm above the upper end of the trap opening at a position higher than the bottom of the ball is the lower limit position of the minimum set water level. .

  However, when the toilet bowl is made of earthenware, the actual position is that the position of the upper end of the trap opening in the ball varies in the vertical direction due to variations in the manufacturing process. Therefore, in order to secure the required “sealing depth” while taking into account the variation in the upper and lower positions of the upper end of the trap opening, the measurement start water level must be set at a higher position. There is also a problem that becomes narrower.

  The problem to be solved by the present invention is that a measurement start water level formed for measuring biological information is accurately formed and maintained at a set predetermined water level so that a toilet used can be a toilet. An object of the present invention is to provide a biological information measuring toilet that can secure the maximum measurement function while maintaining the function as the above.

The living body information measuring toilet of the present invention has a predetermined water level set as a measurement start water level that is a water level at the start of measurement based on a predetermined control condition. A measurement start water level forming means for forming, and a stored water level measuring means for measuring the water level of the stored water,
In the biological information measuring toilet for measuring the amount of change in the stored water level from the measurement start water level due to the excrement of the user with the stored water level measuring means, and measuring biological information including at least the amount of urine,
Start water level confirmation means for measuring the water level of the accumulated water formed as the measurement start water level by the measurement start water level formation means;
A control condition for updating the control condition for controlling the operation of the measurement start water level forming means to a new control condition based on the deviation between the measurement value of the measurement start water level measured by the start water level confirmation means and the predetermined water level. And updating means.

  With such a configuration, the measurement start water level set by trial operation is actually measured by the stored water level measurement means for the Western-style toilet installed at the construction site, and the deviation between the actual measurement value and the set value is obtained. Based on this deviation, the control condition updating means updates the control condition of the measurement start water level forming means to a new control condition, so that the control condition in accordance with the Western-style toilet is obtained. Accordingly, the measurement start water level of the stored water can be set accurately.

  Here, the measurement start water level forming means may form the measurement start water level by discharging a part of the accumulated water stored in the ball. With such a configuration, there is a technical effect that it is possible to create a target measurement start water level with high accuracy with a simple apparatus configuration that only provides a configuration for discharging a part of the accumulated water. can get.

  Moreover, the said measurement start water level formation means can also form the said measurement start water level by supplying water in the ball | bowl after toilet bowl washing | cleaning. With such a configuration, when the measurement start water level is formed, the accumulated water staying in the ball is discharged once, so even if foreign matter such as paper is mixed in the staying accumulated water, Does not affect the water level formation at the start of measurement. For this reason, the target measurement start water level can be created with high accuracy by a measuring device with high operational reliability.

  On the other hand, the control condition update means can update the control condition every time a predetermined period elapses. With such a configuration, the control conditions are periodically updated, which is caused by changes over time in the elements constituting the stored water level forming means such as the water supply capacity of the pump and the flow resistance of the piping. It is possible to correct the water level formation error, and the measurement start water level of the stored water can be accurately maintained.

  In this case, it is desirable that the update of the control condition is repeated as many times as necessary until the updated deviation falls within a predetermined range. With such a configuration, it is possible to achieve a precision that requires a control condition by the above-described repetition, so that the predetermined water level can be set accurately.

  Next, it is desirable that the starting water level confirmation means is the stored water level measurement means. With such a configuration, the predetermined water level of the formed stored water is measured by the originally provided stored water level measuring means, so that no special configuration is required to update the control conditions.

Next, a deviation correction input means for manually inputting the deviation correction instruction is provided,
The starting water level confirmation means may be a measuring jig for measuring a deviation between a distance from a top end of the trap opening of the Western-style toilet to a water surface and a specified distance. With such a configuration, in a biological information measuring toilet installed at a construction site, the water level formed in the ball can be directly measured visually by a construction worker, which is different from measurement using a sensor or the like. In addition, it is not necessary to consider the error amount of the measurement system itself, and it is possible to easily obtain the deviation from the specified sealing depth in the formed water level.

  According to the present invention, the measurement start water level of the stored water can be accurately set at the set predetermined position, so that it is possible to perform the measurement using the maximum water level setting range determined by the toilet used, and the measurement range. A wide biological information measuring toilet can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing a biological information measuring toilet according to a 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 a measurement of the biological information measuring toilet shown in FIG. 4 is a partially omitted vertical sectional view before setting the water level, FIG. 4 is a partially omitted vertical sectional view during setting the measurement water level of the biological information measuring toilet shown in FIG. 1, and FIG. 5 is a measurement water level setting of the biological information measuring toilet shown in FIG. It is a partially omitted vertical sectional view later.

  As shown in FIG. 1, the biological information measuring toilet 10 of the present embodiment incorporates a Western-style toilet 11 that receives a user's excrement and discharges it to a sewage pipe, a biological information measuring unit 12, a control unit 13, and the like. A cabinet 14 and an operation / display unit 20 disposed on a side wall surface of the western-style toilet 11 are provided. The western toilet 11 includes a toilet seat 15 for a user to sit on, 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 prints a remote controller 19 for operating the sanitary washing device 23 provided in the western-style toilet 11, a remote controller 21 for causing the biological information measuring means 12 to function, and a urination information measurement result. A printer 22. The urine collection unit 18 and the sanitary washing device 23 are not essential requirements for configuring the biological information measuring toilet 10 according to the present invention.

  As shown in FIG. 2, the western toilet 11 includes a ball 16 that receives a user's urine, a cleaning unit 34 that supplies toilet cleaning water to the water supply nozzle 24 in the ball 16, and a connection chamber 26 that is partitioned from the atmosphere. The ball 16 and the sewage pipe 35 are communicated with each other, and the trap 25 for storing the stored water for blocking the communication with the sewage pipe 35 is provided except when the toilet bowl is washed.

  As shown in FIG. 3, the trap 25 is formed of a flexible pipe material, and has a rotating portion 25 a that is movably disposed in the connection chamber 26. The end of the rotating portion 25 a is connected to the connection chamber 26. It is a free end 25b opened inside. The free end 25b is moved up and down by the trap rotating means 28 while detecting its position by the position detecting means 37, and excreta in the ball 16 is discharged to the sewage pipe 35, or a measurement start water level is formed. To do. Further, since the connection chamber 26 is connected to a sewage pipe 35, it is integrated with a portion generally called a drain socket, and the connection chamber 26 and the sewage pipe 35 are directly connected as shown in FIG. ing.

  Further, the biological information measuring means 12 housed in the cabinet 14 is provided with a sewage pressure fluctuation measuring means 6, and the control means 13 includes a calibration curve storage means 38, a urination information calculation means 39, an information storage means 40 and a control. Condition update means 43 is provided.

Next, the biological information measurement operation of the present embodiment will be described below with reference to FIGS.
In the biological information measuring toilet 10, the rotating portion 25a is in the position shown in FIG. 3 in the measurement standby state, and the water level of the stored water W1 at that time is the defecation water level W1L. When the user gives a measurement start instruction, as shown in FIG. 4, the trap rotating means 28 lowers the free end 25b, and a part of the stored water W1 above the lowest point 25c of the free end 25b is removed. After discharging and making the stored water W2, as shown in FIG. 5, the measurement start water level W2L which is a predetermined water level lower than the overflow water level H and the measurement range are returned by returning the free end 25b to the original standby state position. The upper overflow water level H is formed. In this case, the lower end point 25c of the free end portion is raised to a position higher than the original standby state position, thereby increasing the overflow water level H of the stored water W1 to ensure a large measurement range. it can.

  In this way, the biological information measuring toilet 10 discharges a part of the stored water W1 stored in the ball 16 of the Western-style toilet 11 via the free end 25b of the trap 25 constituting the discharge path to store the stored water. By setting the stored water level to W2L, which is lower than the overflow water level H, the amount of change in the water level from the measurement starting water level W2L due to the user's urination is measured by the stored water level measuring means 27. To measure biological information including at least urine volume. In this embodiment, the stored water level measuring means 27 uses a pressure sensor capable of measuring the water pressure of the stored water W2. Further, the sewage pressure fluctuation measuring means 6 is connected to the connection chamber 26, and the stored water level measured value by the stored water level measuring means 27 is corrected by the measured value of the sewage pressure fluctuation measuring means 6, and the corrected stored water is corrected. Subsequent urination information is calculated according to the water level.

  When constructing the biological information measuring toilet 10, the trap rotating means 28 is predetermined in order to set the water level of the stored water to a preset measurement start water level by trial operation after the Western-style toilet 11 is installed at the construction site. An operation is performed based on the control conditions, and a part of the stored water W1 is discharged to the sewage pipe 35. Next, the water level formed as the measurement start water level is measured by the stored water level measurement means 27, and the deviation from the set value of the actual measurement value obtained is obtained. Next, the control condition update unit 43 updates the control parameter of the control condition that controls the operation of the trap rotation unit 28 for forming the measurement start water level W2L to a new control condition that is corrected by an amount corresponding to the obtained deviation. To do. In the present embodiment, the control parameter to be corrected is the positional information of the trap rotating means 28, and the deviation from the set value of the position shown in FIG.

  When the control condition is updated, if the water level deviation formed under the updated new control condition does not fall within the target tolerance, a similar update operation is again made within the tolerance. Try to repeat. Therefore, a more accurate measurement start water level can be set efficiently.

  In this way, for the Western-style toilet 11 installed at the construction site, based on the control conditions set in advance by trial operation, the water level formed by actually performing the measurement start water level forming operation is measured. And the measurement start water level W2L is obtained in advance as a predetermined value, and based on this, the control condition update means 43 controls the control condition of the operation for forming the measurement start water level W2L by an amount corresponding to the deviation. Since the parameters are updated to the new control conditions corrected, the control conditions conforming to the Western toilet 11 can be obtained, taking into account variations in the shape of the balls 16 and variations in the operation of the trap rotating means 28. Therefore, the measurement start water level W2L of the stored water W2 can be set accurately.

  Further, if necessary, this operation is performed periodically (for example, every month) to update the control conditions, so that the response speed of the valve constituting the water level forming means, the flow resistance of the water channel, etc. Since the formation error of the measurement start water level due to the change over time of the water level formation operation due to the fluctuating factor is corrected, the formed measurement start water level W2L can always be maintained at an accurate set value.

  Like the Western-style toilet 11 shown in FIGS. 3 to 5, the toilet having a configuration in which the free end portion 25b of the trap 25 is moved up and down at the time of cleaning the toilet is larger in trap structure than a general fixed-trap toilet. Since it does not require energy to overcome the running water level, it has a feature that the sound for discharging the wastewater mixed wastewater into the sewage pipe is small. However, after the user finishes excretion, when the next toilet flushing operation is started when the free end 25b of the trap 25 is at the position where the defecation standby water level is formed, the free end 25b of the trap 25 is connected to the sewage pipe 35. And the discharge of the contents in the ball 16 is started. However, only the accumulated water is discharged first, and excrement having a large specific gravity is left in the flow of the accumulated water W1 in the accumulated water W1. May remain on the ball 16.

  Therefore, in the present embodiment, when the toilet bowl cleaning is started, first, the free end portion 25b of the trap 25 is moved to a position higher than the defecation standby water level, and then the ball 16 for cleaning the inner surface of the ball 16 that is implemented during toilet bowl cleaning. Since the amount of the stored water W1 when the free end portion 25b of the trap 25 starts to descend is increased by supplying water, the amount of discharged matter that can be discharged by discharging the stored water is increased. Accordingly, it is possible to prevent a phenomenon in which excrement having a large specific gravity is left in the flow of the stored water W1 and remains in the ball 16.

  Even in a toilet without a measuring function, it is possible to increase the amount of accumulated water by raising the free end portion 25b of the trap 25, so that the cleaning ability of the western toilet 11 can be improved. Moreover, the timing which raises the free end part 25b of the trap 25 is not only implemented according to the washing | cleaning operation | movement of the ball | bowl 16 inner surface implemented first after receiving the washing | cleaning operation of excrement, but as a structure implemented prior to defecation. Also good.

  Next, based on FIGS. 6-8, 2nd embodiment of this invention is described. 6 is a perspective view showing a biological information measuring toilet according to a second embodiment of the present invention, FIG. 7 is a system block diagram of the biological information measuring toilet shown in FIG. 6, and FIG. 8 is one of the biological information measuring toilets shown in FIG. FIG. 6-8, the part which attached | subjected the code | symbol same as the code | symbol shown in FIGS. 1-5 is a part which has the same structure and function as the component part of the biological information measurement toilet 10, and abbreviate | omits description. To do.

  As shown in FIG. 6, the biological information measuring toilet 90 of the present embodiment has the same basic configuration as the Western toilet 11 of the first embodiment of the present invention described above, and a Western toilet 11x incorporating the sanitary washing device 23. And a cabinet 14 in which the biological information measuring means 12 and the control means 13 are housed, and an operation / display unit 20.

  As shown in FIG. 7, the western-style toilet 11 x has a trap 25 for storing stored water that blocks communication with the sewage pipe, and is connected to the sewage pipe 35 through the drain socket 9. In addition, the water supply path is connected to a stop cock 3 to which city water is supplied via a branch fitting 34, and further to the water supply path 24L to the rim water discharge nozzle 24a and the jet water discharge nozzle 24b by the water path switching means 4. And a water supply path 24J.

  The biological information measuring means 12 is provided with a water replenishing means 45, a stored water level measuring means 47, a calibration curve setting means 8, a calibration means 7 and a sewage pressure fluctuation measuring means 6. The control means 13 is provided with a calibration curve storage means 38, a urination information calculation means 39, an information storage means 40, and a sewage pressure fluctuation correction means 5.

  As shown in FIG. 8, a measurement pipe 48 is disposed toward the biological information measuring means 12 by branching from a branch fitting 36 provided in the middle of the water supply path 24J to the jet water discharge nozzle 24b. The measurement pipe line 48 communicates from the jet water discharge nozzle 24b to the water replenishing means 45, the stored water level measuring means 47, etc. via the foreign matter removing means 29, the water stop cock 42, and the like. In the present embodiment, the foreign matter removing means 29 is a strainer, and the stored water level measuring means 47 is a pressure sensor that measures the water pressure of the stored water via a measurement pipe line 48 communicating with the stored water in the ball 16. However, the present invention is not limited to these members.

  An outline of a method for measuring biological information in the biological information measuring toilet 90 will be described below. First, in order to form the measurement start water level W3L lower than the overflow water level H, all the accumulated water in the ball 16 is discharged by the toilet cleaning process, and then the water is supplied into the ball 16 in two stages. That is, as the first stage of water supply, high-speed water supply from the rim water spouting nozzle 24a is performed after filth is discharged at the time of cleaning the toilet bowl, and the water level in the ball 16 is slightly lower than the measurement start water level W3L in a short time. To form. Thereafter, as the second stage water supply, water in the water supply tank 46 is supplied into the ball 16 through the jet water discharge nozzle 24b at a relatively low speed by the water replenishing means 45 constituted by the water supply tank 46 and the pump P1. Thus, the measurement start water level W3L is accurately formed at a predetermined water level.

  When the user urinates to the ball 16 in this state, the water level of the stored water W3 rises above the measurement start water level W3L, and the water pressure change at that time is measured by the stored water level measuring means 47. Then, based on the measured value by the stored water level measuring means 47 and the record data stored in the calibration curve storage means 38 in advance, the urination information calculating means 39 calculates various biological information such as urine output and urine volume rate. Then, the information is recorded in the information storage means 40 and the measurement result is displayed on the operation / display unit 20.

  When constructing the biological information measuring toilet 90, a Western-style toilet 11x is installed at the construction site, a trial operation is performed, and an actual value obtained by measuring the formed water level with the stored water level measuring means 47 and a measurement start water level W3L. A deviation from a preset value is obtained. Next, the control condition for the formation operation of the measurement start water level W3L stored in advance is updated to a new control condition in which the control parameter update unit 43 corrects the control parameter corresponding to the deviation.

  In the present embodiment, the control parameter of the control condition to be corrected is the water supply amount when water is supplied into the ball 16 by the pump P1 in the low-speed water supply operation described above. When the control condition is updated, the same update operation is repeated until the deviation of the water level formed under the updated new control condition falls within the target tolerance.

  Thus, for the Western-style toilet 11x installed at the construction site, the deviation between the actually measured value and the set value obtained by actually measuring the water level formed under the control conditions set in advance by trial operation is obtained, and based on the result. Since the control condition of the measurement start water level forming means is updated to a new control condition in which the control parameter corresponding to the deviation is corrected, the control condition conforming to the Western toilet 11x is obtained. Therefore, the measurement start water level W3L of the stored water W3 can be set accurately.

  In the case of this embodiment, as described above, it is a parameter of the control condition of the pump P1 that supplies water at a low speed among the two types of water supply means of the water channel switching means 4 and the water replenishing means 45 constituting the measurement start water level forming means. The amount of water supply is corrected according to the test operation result. That is, the configuration is such that the variation in the amount of water supplied by the water channel switching means 4 is relatively large with respect to the amount of water to be carried out by correcting the operation control conditions of the pump P1 where the variation in operation is relatively small. Therefore, the measurement start water level forming operation is controlled in consideration of not only the shape variation of the ball 16 but also the operation variation of the water channel switching means 4, and the forming operation becomes accurate and quick.

  In addition, even after construction, factors that change with time such as the water supply operation speed by periodically performing such an operation to update the control conditions of the measurement start water level W3L as necessary (for example, every month). Therefore, it is possible to maintain an accurate measurement starting water level forming operation that eliminates the influence of the above.

  Next, based on FIG. 8, FIG. 9, FIG. 10, and FIG. 11, the setting update operation of the measurement start water level after constructing the biological information measuring toilet 90 will be described. FIG. 9 is an operation flowchart when manually setting the measurement start water level after constructing the biological information measurement toilet shown in FIG. 8, and FIG. 10 is the case where the measurement start water level is automatically set after constructing the biological information measurement toilet shown in FIG. FIG. 11 is a perspective view showing an example of a water level confirmation jig used when manually setting the measurement start water level.

When manually setting the measurement start water level W2L, as shown in FIGS. 8 and 9, when the construction of the drain socket 9 is finished (step 50), the western-style toilet 11 is installed (step 51), and the cabinet 14 is installed. (Step 52). Then, the biological information measuring function unit is installed in the cabinet 14 (step 53), and then the water faucet 3 is opened to allow the biological information measuring toilet 10 to pass through the water (step 54). To release the air from the functional part piping (step 55). Thereafter, the calibration curve is set (step 56) and recorded in the calibration curve storage means 38. Next, when the measurement start water level setting operation is performed (step 57), the control parameter T _n of the control condition for controlling the operation of the measurement start water level forming means stored in the control means 13 is read (step 58). .

Next, the measurement start water level is formed under the control condition of the control parameter T _n (step 59), and the stored water level is set to the measurement start water level W3L. Thereafter, the operator attaches the water level confirmation jig 50 of the sealing depth shown in FIG. 11 to the western-style toilet 11x (step 60), and the deviation between the actually measured value and the set value is attached to the water level confirmation jig 50. The scale 54a is visually checked (step 61). Then, it is determined whether or not the deviation is within a predetermined tolerance (step 62).

At this time, if the deviation is outside the predetermined tolerance, it is determined whether or not the deviation is a positive deviation (step 63). If the deviation is + side deviation, by entering the deviation by operating the drawdown switch (step 64), the control parameter T _n by the control condition update unit 43 illustrated in FIG. 7, the water level to be formed deviations Is changed to a new control parameter T _{n + 1} which is a lower water level (step 65). On the other hand, if the deviation is a negative deviation, when the amount of deviation is input by operating the water level rise switch (step 71), the control condition update means 43 causes the water level at which the control parameter _Tn is formed to increase by the deviation. Is changed to a new control parameter T _{n + 1} that becomes the water level (step 72). Thereafter, the above-described measurement start water level formation operation is performed under the new control condition changed to the control parameter T _{n + 1} (step 59), and the measurement start water level formation (step 59) and subsequent steps until the deviation falls within a predetermined tolerance. Is repeated.

  In addition, although the case where the deviation amount from the target value is input in the above-described step 64 and step 71 has been described, the deviation amount to be corrected by one operation is determined in advance, and the deviation amount is within a predetermined tolerance. You may repeat as many times as necessary. In this case, while setting takes time, there is an advantage that the input operation can be simplified.

  If the deviation measured in the above procedure is within the predetermined tolerance, the control condition at that time is updated as the final control condition by the control condition update means 43 (see FIG. 7) (step 73), and the toilet The control conditions of the measurement start water level formation operation taking into account the shape variation are determined.

  Next, a timer for recording the elapsed time since the update of the control condition as an update history is started (step 74), the measurement preparation is completed, and the operation mode of the biological information measuring toilet 90 becomes the operation mode in which the measurement is performed ( Step 75). Thereafter, it is determined whether or not a predetermined time set in advance has passed (step 76). When it is confirmed that the predetermined time has passed, update of the control condition is guided (step 77), and measurement is started. The necessity of confirming the forming operation of the water level forming means is notified. For this reason, the installer of the biological information measuring toilet 90 can accurately know the time of maintenance, and the function of the apparatus can always be kept normal.

  Next, when the measurement start water level is automatically set, as shown in FIG. 10, the process from the construction of the drain socket 9 (step 50) to the formation of the measurement start water level (step 59) is performed manually as shown in FIG. Same as setting.

As shown in FIGS. 8 and 10, when the operation of forming the measurement start water level W3L is completed (step 59), the water level is measured by the stored water level measurement means 47 (see FIG. 7) as the start water level confirmation means ( Step 80), the deviation between the measured value and the set value predetermined as the measurement start water level is calculated (Step 81). Next, it is determined whether or not the deviation is within a predetermined tolerance (step 82), and when the deviation is outside the predetermined tolerance, a correction amount calculation of a control parameter of the control condition is performed based on the deviation amount. after it has been performed (step 83), updates to the control condition update unit 43 controls the control parameter T _n is corrected by the correcting amount equivalent (see FIG. 7) parameters T _{n + 1} is performed (step 84 ). Thereafter, the above-described measurement start water level formation operation is performed under the new control condition changed to the control parameter T _{n + 1} (step 59), and the above-described measurement start water level formation operation (step) is performed until the deviation falls within a predetermined tolerance. 59) The subsequent operations are repeated.

  If the deviation measured by the procedure as described above falls within the predetermined tolerance, the control condition at that time is updated as the final control condition by the control condition update means 43 (step 85), and the shape variation of the western-style toilet 11x is corrected. The control conditions for the formation operation of the weaving measurement start water level are determined.

  Thereafter, the elapsed time recording timer is started (step 86) and the mode is switched to the operation mode (step 87) in the same procedure as in the manual setting described above, and thereafter, a predetermined time set in advance is set. Is determined (step 88), and the control condition is updated every time a predetermined time has elapsed. In the present embodiment, the configuration using the stored water level measurement unit 47 used for the biological information measurement as the starting water level confirmation unit has been described. However, the configuration using the water level measurement unit provided separately from the stored water level measurement unit 47 is used. Can achieve the same effect.

  As described above, the control condition update method has been described by taking the biological information measuring toilet 90 according to the second embodiment of the present invention as an example. However, the same method is applied to the biological information measuring toilet 10 according to the first embodiment of the present invention. Is possible.

  Next, based on FIG. 8 and FIG. 11, the water level confirmation jig | tool 50 used when setting the measurement start water level shown in FIG. 9 manually is demonstrated. As shown in FIG. 11, the water level confirmation jig 50 includes a flat shoulder 52 that can be locked to the rim surface B of the western-style toilet 11 x shown in FIG. 8, and an approximate shape of one side edge of the shoulder 52. The elastic part 53 and the scale board 54 which were formed in the shape of hanging from the center are provided, and the tongue piece part 51 arrange | positioned in parallel with the shoulder part 52 in the lower edge part of the scale board 54 is provided. The scale plate 54 is marked with a scale 54a and a setting line 54b for confirming the stored water level.

  When the water level confirmation jig 50 is used, the shoulder 52 is placed on the rim surface B of the western toilet 11x, and the tongue piece 51 is hooked on the sealing edge (the upper end of the trap opening) A in the ball 16. At this time, since the elastic part 53 which can be expanded and contracted is provided between the tongue piece part 51 and the shoulder part 52, the water level confirmation jig 50 rattles against the western-style toilet 11x by the contraction force of the elastic part 53. It can be locked without. Since the setting line 54b indicating the position of the predetermined sealing depth is marked on the surface of the scale plate 54 of the water level confirmation jig 50, whether or not the measurement start water level is the predetermined sealing depth indicated by the setting line 54b during the test operation. Can be visually confirmed. Therefore, if the water level confirmation jig 50 is used when manually setting the measurement start water level, it can be easily determined whether or not the deviation between the actually measured value and the set value is within a predetermined tolerance.
