Description

  The present invention relates to a urine temperature measuring device, a sanitary washing device, and a sanitary device that measure the temperature of urine excreted by a user.

  Conventionally, body temperature, which is the temperature of the body, has been used as one of the indices for grasping the health state of the body. As this body temperature measuring method, there has been a method of measuring the body temperature of the body surface part by bringing a thermometer or the like into contact with the skin. And the necessity of this body temperature measurement is increasing as the health management orientation in individuals increases. However, in this measurement method using a thermometer, variations due to measurement are likely to occur, and it is difficult for anyone to easily measure an accurate body temperature. Further, when an actual measurement thermometer was used to accurately measure the body temperature, it took about 10 minutes for the armpit temperature measurement and about 6 minutes for the sublingual temperature measurement, and the measurement took time.

  On the other hand, since urine produced in the body accumulates in the body, it is also called deep body temperature, and has a temperature reflecting the body temperature inside the body. It has been known that this deep body temperature more accurately represents the health of the body as compared to the body temperature which is the temperature of the body surface described above. Therefore, it is possible to estimate this deep body temperature by measuring the temperature of urine immediately after being excreted outside the body by excretion (hereinafter, the temperature of urine during excretion is also referred to as “urine temperature”). Compared with typical body temperature, more accurate physical health information can be obtained. For this purpose, there is a demand for a method of easily measuring with accuracy higher than the conventional temperature measurement accuracy.

  Therefore, various urine temperature measuring devices for measuring the urine temperature during excretion of the user without contact with urine have been proposed.

  As a temperature measuring means provided in such a urine temperature measuring device, for example, using an electrical element that receives an infrared ray radiated from the object surface according to its temperature and obtains an electrical output proportional to the amount of received light, There is a radiation infrared detection type temperature measurement means (hereinafter, this radiation infrared detection type temperature measurement means is also referred to as “radiation temperature measurement means”) that can measure the temperature of an object in a non-contact manner. According to the urine temperature measuring device using this radiation temperature measuring means, the time required for measuring the urine temperature is the urine excretion time, that is, about 30 seconds, which is compared with the body temperature measuring time by a general actual measurement thermometer. ,short.

  As a urine temperature measuring device using such a radiation temperature measuring means, for example, this radiation temperature measuring means is provided on the ceiling surface of a urinal, and infrared rays emitted from urine passing through the measurement region are received and the temperature of the urine is measured. A non-contact type urine temperature measurement device that performs measurement is known (Patent Document 1).

  In this prior art urine temperature measuring device, in order to accurately measure the urine temperature, a urinal temperature setting sensor for calibration is provided at a position where the urine does not come into contact with the urinal, and the measured value of the radiation temperature measuring means and the calibration It is possible to correct the deviation of the measured value generated between the measured value of the toilet temperature setting sensor.

(Regarding the generation of the relational expression between the voltage value output by the light receiving unit and the water temperature)
FIG. 3 is a plan view of the sanitary washing apparatus of FIG. 1, and FIG. 4 is a schematic diagram showing an operation of detecting infrared rays from water discharged from the washing nozzle in the light receiving unit of FIG.

  As shown in FIG. 3, for example, the washing nozzle 12 is located on the center line O of the western-style toilet 4 when viewed from the front of the western-style toilet 4, and the light receiving unit 16 is located on the right side of the washing nozzle 12. The detection unit 10 is located on the left side of the cleaning nozzle 12. However, the embodiment mobile phone is not limited to this, and may be provided anywhere in the sanitary washing device 6 of the urine temperature measuring device 1.

  The cleaning nozzle 12 is provided with a toilet water discharge hole 12a and a local water discharge hole 12b. The washing nozzle 12 discharges water from the water supply source 100 toward the bowl 2 of the western-style toilet 4 from the toilet spout 12a (first discharge mode), and then discharges water upward from the local spout 12b. The local area of the user is washed by discharging (second discharge mode). Further, these water discharge holes can be switched by changing the flow path provided inside the cleaning nozzle 12. These switching operations can be performed by operating the remote control device 8a. Further, in the sanitary washing device 6, a heater 13 that is a temperature switching unit is provided in the flow path between the washing nozzle 12 and the water supply source 100, and the temperature of water discharged from the washing nozzle 12 is set to a set temperature. Can be changed. The temperature switching unit is not limited to the heater, and any mechanism that can change the temperature of the water flowing through the flow path in any way, such as a mixing valve that mixes water having different temperatures, may be used.

  A measuring unit 14 is connected to the cleaning nozzle 12, and the temperature of water discharged from the cleaning nozzle 12 can be measured by the measuring unit 14. The measuring unit 14 is composed of a circuit including a thermistor and measures the temperature of water.

  As shown in FIG. 3, the light receiving unit 16 detects the amount of infrared rays emitted from a certain range of the bowl portion 2 (hereinafter, this fixed range is referred to as “infrared light receiving region A”). A voltage value is output according to the detected amount of infrared rays. As shown in FIG. 3, the infrared light receiving region A is located in a region on the front side of the bowl portion 2 and not in contact with the accumulated water accumulated in the bowl portion 2. More specifically, assuming that the infrared light receiving area A is substantially circular, the center point of the infrared light receiving area A is located on the center line O, for example.

  That is, as shown in FIG. 4, the light receiving unit 16 receives the infrared rays collected by the lens 16 a and the lens 16 a that collects incident infrared rays, and outputs a voltage value according to the amount of received infrared rays. The thermopile element 16b, the lens 16a, and the thermopile element 16b are covered so that the infrared rays collected by the lens 16a are incident on the thermopile element 16b without leakage, and the voltage value output by the thermopile element 16b And an A / D converter 16e that digitally converts the amplified voltage value for each predetermined threshold value.

  FIG. 5 is a flowchart showing an operation of generating a relational expression between the voltage value output by the light receiving unit and the temperature of water in the urine temperature measuring device of FIG.

  When the detection unit 10 detects the user (S100), the generation unit 18 sets the water discharge temperature to a low temperature setting, that is, the first temperature T1 (S101), and the infrared light receiving region from the toilet water discharge hole 12a of the washing nozzle 12 Water is discharged toward A (S102). In the present embodiment, the first temperature T1 is, for example, 37 degrees.

  The generation unit 18 outputs the light receiving unit 16 with the temperature T1 ′ output from the measurement unit 14 by the water discharged from the toilet water spouting hole 12a and the infrared ray radiated from the water discharged from the toilet water discharging hole 12a. The obtained voltage value V1 is acquired (S103) and stored in the storage unit 22. Thereafter, the discharge of water from the cleaning nozzle 12 is stopped (S104).

  Next, the generation unit 18 sets the water discharge temperature to a high temperature, that is, the second temperature T2 (S105), and discharges water from the toilet water discharge hole 12a of the cleaning nozzle 12 toward the infrared light receiving region A (S106). . Here, the second temperature T2 is higher than the first temperature T1, and in the present embodiment, the second temperature T2 is, for example, 42 degrees.

  The light generating unit 18 is configured so that the light receiving unit 16 receives the voltage T2 ′ output from the measuring unit 14 by the water discharged from the toilet water spouting hole 12a and the infrared ray radiated from the water discharged from the toilet water discharging hole 12a. The output voltage value V2 is acquired (S107) and stored in the storage unit 22. Thereafter, the discharge of water from the cleaning nozzle 12 is stopped (S108).

  Thereafter, the generation unit 18 obtains the temperature T1 ′ and the voltage value V1 acquired when the low-temperature water discharge is performed from the toilet water discharge hole 12a, and the temperature T2 ′ and the voltage value V1 acquired when the high-temperature water discharge is performed from the toilet water discharge hole 12a. A voltage-temperature relational expression is generated based on the voltage value V2 (S109). Specifically, as shown in FIG. 6, a linear function expression of the temperature T and the voltage V satisfying the coordinates (T1 ′, V1) and (T2 ′, V2) in the temperature-voltage graph is calculated. In FIG. 6, the vertical axis is the water temperature, and the horizontal axis is the voltage. A linear function expression of the temperature T and the voltage V satisfying the coordinates (T1 ′, V1) and (T2 ′, V2), that is, the voltage-temperature relational expression is as shown below.

  The operation of generating the relational expression between the voltage value output from the light receiving unit 16 and the water temperature is performed every time the detecting unit 10 detects the user. At this time, the storage unit 22 outputs the voltage output from the light receiving unit 16. Store the value. The storage unit 22 stores the voltage values output by the past light receiving unit 16 up to a certain number, and then erases the stored voltage values in order from the oldest one. When the voltage value output from the light receiving unit 16 differs from the voltage value output from the previous light receiving unit 16 stored in the storage unit 22 by, for example, ± 10% or more, the notification unit 24 stains the lens 16a of the light receiving unit 16 or the like. It is determined that is attached, and an electronic sound is generated. As a result, the user can recognize the necessity of cleaning the light receiving unit 16.

(Regarding the urine temperature measurement operation by the urine temperature measurement device in the present embodiment)
FIG. 7 is a flowchart showing a urine temperature measuring operation in the urine temperature measuring apparatus of FIG.

  When the user is excreting urine, by pressing a urine temperature measurement start switch (not shown) provided in the remote control operation portion 8a (S200), the light receiving portion 16 is an infrared ray located in the bowl portion 2. An infrared detection operation in the light receiving area A is started, and an infrared ray emitted from the urine excreted toward the infrared light receiving area A is detected, thereby obtaining a voltage value V3 corresponding to the amount of infrared rays at that time (S201). ).

  The calculation unit 20 calculates the urine temperature at that time by applying the obtained voltage value V3 to the voltage-temperature relational expression generated by the generation unit (S202). Thereafter, by displaying the calculated urine temperature on the remote control display unit 8b, the user can be notified of the urine temperature (S203).

  In the present embodiment, the light receiving unit 16 of the urine temperature measuring device 1 outputs a voltage value corresponding to the amount of received infrared light by the thermopile element 16b. The thermopile element 16b generates a voltage corresponding to the difference between the temperature of the thermopile element 16b itself and the infrared ray amount of the measurement object, that is, the temperature. If the temperature of the thermopile element 16b changes, the same infrared ray amount is generated. Even if light is received, the output voltage value is different. That is, the output voltage value varies depending on the temperature of the toilet booth in which the urine temperature measuring device 1 is provided. However, in the urine temperature measuring device 1 of the present invention, the voltage-temperature relational expression is not generated before the factory shipment of the urine temperature measuring device 1 and the Western-style toilet 4, but after the factory shipment, that is, after construction on the site. Since the voltage-temperature relational expression can be generated, the voltage-temperature relational expression can be generated according to the season and on-site environment even when the thermopile element 16b is used for the light receiving unit 16, and the urine temperature is accurately measured. can do.

  Further, as described above, the urine temperature measuring device 1 of the present invention can generate a voltage-temperature relational expression after factory shipment of the urine temperature measuring device 1 and the western toilet 4, that is, after construction on the site, There is no need to perform a voltage-temperature relational expression generation operation in the factory, the delivery time of the shipping work can be shortened, and there is no need for a worker to perform the voltage-temperature relational expression generation operation. Can be taken down.

  As described above, in the present invention, when the sanitary washing device 6 provided with the urine temperature measuring device 1 is installed in the bowl portion 2 that is the receiving portion of the Western-style toilet 4, the water is discharged when the water is discharged. Since the first parameter is output by the unit 18 according to the amount of electromagnetic waves of water hitting the bowl unit 2, the calculation unit 20 corresponds to the installation environment such as the shape of the bowl unit 2 in which the sanitary washing device 6 is installed. The urine temperature can be calculated based on the relational expression, and the urine temperature can be accurately calculated regardless of the urine flow shape.

  In the present invention, the urine temperature measuring device 1 does not measure the amount of infrared rays only in the bowl portion 2 that is a receiving portion of the Western-style toilet 4, but is discharged from the washing nozzle 12 that is a discharge portion. It measures the infrared amount of water and generates a voltage-temperature relationship. In order to generate the voltage-temperature relational expression, it is necessary to measure the temperature of the object to be measured at two points. Therefore, the method of measuring the infrared amount of only the bowl part 2 of the Western-style toilet 4 shows the temperature of the bowl part 2 That is, it is necessary to change the temperature of the toilet booth where the Western-style toilet 4 is provided, and this is difficult to execute. However, the method of measuring the infrared amount of water discharged from the cleaning nozzle 12 according to the present invention can easily perform two-point measurement simply by changing the temperature of the discharged water. A voltage-temperature relationship can be generated.

(Modification)
As mentioned above, although embodiment of the technique which this application discloses was described, the technique which this application discloses is not limited above.

  For example, in the present embodiment, the sanitary washing device 6 provided with the urine temperature measuring device 1 is placed on the western toilet 4, but is not limited thereto, and is incorporated into the western toilet 4. Also good. Moreover, you may install not only a western style toilet bowl but other sanitary equipment, such as a urinal.

  In the present embodiment, the infrared light receiving area A, which is the light receiving area of the light receiving section 16 of the urine temperature measuring device 1, is located on the front side of the bowl section 2 and in an area that does not come into contact with the water accumulated in the bowl section 2. However, the present invention is not limited to this, and any inner surface of the bowl portion 2 may be used as long as it is located in a region that does not contact the accumulated water accumulated in the bowl portion 2. However, the urine excreted by the user toward the Western-style toilet 4 is often discharged to the front side of the bowl portion 2 in order to hit the accumulated water accumulated in the bowl portion 2 and suppress the scattering of the urine. Therefore, it is preferable that the infrared light receiving area A is located in an area on the front side of the bowl portion 2 and not in contact with the accumulated water accumulated in the bowl portion 2.

  In this embodiment, the cleaning nozzle 12 is provided with a toilet water discharge hole 12a in addition to the local water discharge hole 12b, and a voltage-temperature relational expression is generated using water discharged from the toilet water discharge hole 12a. However, the voltage-temperature relational expression may be generated using the water discharged from the local water discharge holes 12b. In that case, water is applied to the infrared light receiving region A which is the light receiving region of the light receiving unit 16 by adjusting the flow rate of the water discharged from the local water discharge hole 12b. In this case, the flush nozzle 12a may not be provided in the cleaning nozzle 12.

  In the present embodiment, the discharge portion of the urine temperature measuring device 1 has been described as the washing nozzle 12, but it may be a spout provided in the western toilet 4 and washing the western toilet 4. In that case, the voltage-temperature relational expression is generated by using the wash water discharged from the water outlet and washing the Western toilet 4.

  In the present embodiment, the generation unit 18 of the urine temperature measuring device 1 sets the first temperature T1 of the water discharged from the washing nozzle 12 to 37 degrees and the second temperature T2 to 42 degrees. The two temperatures T2 may be higher than the first temperature T1. However, since the first temperature T1 and the second temperature T2 can generate a voltage-temperature relational expression more accurately when the value is close to the body temperature, at least one of the first temperature T1 and the second temperature T2 is 35 degrees. It is preferable to set between 42 degrees and 42 degrees, and it is more preferable to set both the first temperature T1 and the second temperature T2 between 35 degrees and 42 degrees. Moreover, in this embodiment, although the water set to 1st temperature T1 was discharged before the water set to 2nd temperature T2, you may set the discharge order reversely. That is, the same voltage-temperature relational expression can be generated even if the water set at the second temperature T2 is discharged before the water set at the first temperature T1. However, since the water set to the second temperature T2, which is higher than the first temperature T1, takes more time to warm up to the set temperature than the water set to the first temperature T1, it is set to the first temperature T1. The discharged water is preferably discharged before the water set at the second temperature T2. By adopting such a configuration, the water set at the second temperature T2 can be warmed up to the set temperature by using the time during which the water set at the first temperature T1 is being discharged. is there.

  Further, the discharge time for discharging water set to the second temperature T2 from the cleaning nozzle 12 may be changed depending on the season. By adopting such a configuration, for example, in the winter (the day when the daily minimum temperature is 0 ° C. or lower, or 10, 11, 12, 1, 2, and March), the cleaning nozzle is used from other seasons. Since it takes time to warm the water discharged from 12 to the set temperature, the water discharge time set at the second temperature T2 is made longer than the water discharge time set in summer, so that the second temperature Time for warming the water set to T2 to the set temperature can be obtained.

  In the present embodiment, the generation unit 18 of the urine temperature measurement device 1 generates a voltage-temperature relational expression that is a linear function, but the voltage-temperature relational expression is defined by other functions such as a quadratic function. May be.

  In the present embodiment, the generation unit 18 of the urine temperature measuring device 1 automatically performs the generation operation of the voltage-temperature relational expression when the detection unit 10 detects the user. A switch for generating a voltage-temperature relational expression may be provided in the operation unit 8a, and the generation operation of the voltage-temperature relational expression may be performed using this switch as a trigger. Further, it may be set such that the operation of generating the voltage-temperature relational expression is automatically performed at a specified time by operating the remote controller operation unit 8a.

  In the present embodiment, the light receiving unit 16 of the urine temperature measuring device 1 starts an infrared detection operation in the infrared light receiving region A located in the bowl unit 2 by pressing a urine temperature measurement start switch provided in the remote control operation unit 8a. However, the present invention is not limited to this, and a seating detection unit for detecting the user's seating on the Western-style toilet 4 is newly provided. When the seating detection unit detects the user's seating, the infrared ray is automatically detected. The detection operation may be started.

  In the present embodiment, the notification unit 24 of the urine temperature measurement device 1 is configured such that the voltage value output by the light receiving unit 16 differs from the voltage value output by the previous light receiving unit 16 stored by the storage unit 22 by ± 10% or more. However, the present invention is not limited to this, and the generation unit 18 calculates the average value of the voltage values stored so far in the storage unit 22, and the voltage value output by the light receiving unit 16 is If the calculated average value is a value that differs by a certain value or more, the notification unit 24 may perform notification. In addition, the notification method of the notification unit 24 is not limited to the generation of an electronic sound, and a cleaning mark or the like is displayed on the remote control display unit 8b of the remote control device 8, or a light emitting unit that emits light is newly provided and blinked. Also good.

  In the present embodiment, the various controls of the sanitary washing device 6 are performed by the generation unit 18 that is the microcomputer 26 of the urine temperature measuring device 1, but the control circuit provided in the sanitary washing device 6 is not limited thereto. That's fine.

  In the present embodiment, it has been described that the light receiving unit 16 of the urine temperature measuring device 1 receives infrared rays emitted from water or urine, but since infrared rays are also emitted from the bowl portion 2 of the western-style toilet 4, The light receiving unit 16 may output a voltage value in consideration of infrared rays emitted from the bowl unit 2.
