Description

  The present invention relates to a urine temperature measuring device that measures the temperature of urine excreted by a subject in a non-contact manner.

  Conventionally, the 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, and a measurement accuracy of at least 0.1 ° C. or more is required. As a method for measuring the body temperature, there is 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.

  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 this urine immediately after being discharged out of the body due to excretion, and more accurate physical health information can be obtained compared to general body temperature. It will be. 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 that measure the temperature of the urine during excretion of the subject (hereinafter, the temperature of the urine during excretion is also referred to as “urine temperature”) have been proposed.

  As the temperature measuring means provided in such a urine temperature measuring device, for example, the present invention is an electric element that receives infrared rays radiated from the surface of an object according to its temperature and obtains an electrical output proportional to the amount of received light. 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”) which can measure the temperature of an object in a non-contact manner using the temperature measuring element in FIG. is there.

  Since this radiation temperature measuring means is configured to condense infrared rays radiated from an object onto the temperature measuring element surface using an optical system such as a condensing lens, all objects existing in the measurement region are The sum of the radiated infrared rays will be measured. Therefore, in order to accurately measure the temperature of an object, it is necessary to match the measurement region only to the object to be measured.

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

Japanese Patent Laid-Open No. 04-203128

However, in the urine temperature measuring device arranged in the conventional urinal described above, since the subject urinates in a standing position on the urinal, the difference between the position of the subject at the time of measurement and the difference in height is directly reflected. The position of the urethral tip of the subject is greatly different.
Therefore, the route of urination until the urine flow reaches the bowl surface from the urethral tip (hereinafter, this route is also referred to as “urination route”) varies greatly depending on the subject. Is difficult to follow.

  Also shown is a method (FIG. 4) for measuring the surface temperature change due to the urine flow of a member (infrared transmitting plate 3) that forms part of the bowl surface.

  Although this method has a wide range of measurement targets of the radiation temperature measurement means, since it is an indirect measurement using the heat transfer phenomenon due to contact with urination, even if the preheating measures shown in other forms are combined, The measured temperature is affected by other factors such as the heat capacity of the member, and it is difficult to measure temperature quickly and accurately.

  Furthermore, the configuration of using the urinal has a problem that the subject is limited to males as a result of the difficulty of female use.

  The present invention has been made in view of such circumstances, and in measuring the urine temperature of a subject, the urine temperature capable of performing urine temperature measurement as accurately as possible without being affected by differences in gender and height. The object is to provide a measuring device.

In order to solve the above-described conventional problem, the urine temperature measuring device according to claim 1 is a measurement that receives infrared rays emitted from the temperature measurement region having a predetermined area and measures the temperature in the temperature measurement region. In a urine temperature measuring device comprising a urine temperature measuring means having a temperature element and measuring the temperature of urine excreted by a subject in a non-contact manner, a Western-style toilet having a bowl surface for receiving urine excreted by the subject, A urine flow collision position recognition unit that physically detects a position where the urine collides with the bowl surface, and recognizes a position detected by the urine flow collision position detection unit as a urine flow collision position. And a temperature detection region position setting means for setting a position of the temperature detection region, and the temperature detection region position setting means is formed around the urine flow collision position based on the urine flow collision position. A predetermined temperature distribution range And setting the temperature measuring urine flow area having.

  Further, in the urine temperature measuring device according to claim 2, in the urine temperature measuring device according to claim 1, the temperature detection region setting means is a predetermined distance below the urine flow collision position in the temperature detection urine flow region. The temperature measurement region is set at a predetermined position.

In the urine temperature measuring device according to claim 3, the subject has a temperature measuring element that receives infrared rays radiated from a temperature measuring region having a predetermined area and measures the temperature in the temperature measuring region. In a urine temperature measuring device having a urine temperature measuring means for measuring the temperature of urine excreted in a non-contact manner, a Western-style toilet having a bowl surface for receiving urine excreted by a subject, and the urine hits the bowl surface A urine flow collision position recognition means for recognizing the position as a urine flow collision position; and a temperature detection area position setting means for setting the position of the temperature detection area, wherein the temperature detection area position setting means is based on the urine flow collision position. The temperature measurement region is set around the urine flow collision region formed around the urine flow collision position and having a predetermined temperature distribution range, and the temperature measurement region setting means is configured to set the urine flow collision in the temperature measurement urine flow region. Below a certain distance from the position Of setting the temperature detecting area at a predetermined position, a target which is a measure of the urination position when urination has target display means for displaying on said bowl surface, the urine flow collision position recognition means, said target display means The display position is recognized as a urine flow collision position.

  Further, in the urine temperature measuring device according to claim 4, in the urine temperature measuring device according to claim 3, the target display means displays the target on the bowl surface by a projected light image. Features.

  Moreover, in the urine temperature measuring device according to claim 5, in the urine temperature measuring device according to claim 4, the target position adjustment that enables the subject to move the position where the optical image is displayed to an arbitrary position. Means are provided.

  According to the first aspect of the present invention, the observation area of the urine temperature measuring means is expanded by making the urine in the area of the predetermined temperature distribution range that has spread by colliding with the bowl surface the measurement target of the urine temperature measuring means. In addition, since the temperature of the urine that is not cooled by the urination route is also measured, the urine temperature can be measured with high accuracy and reliability.

  According to the second aspect of the present invention, the region formed more widely and stably under the influence of gravity is set as the measurement target region of the urine temperature measuring means. A state suitable for temperature measurement can be maintained, and the urine temperature can be measured with high accuracy and stability.

  Furthermore, according to the invention described in claim 3, since the urine flow collision position recognition means does not actually detect the urine flow collision position but regards a predetermined position as the position, The configuration of the collision position recognizing means can be simplified, and highly accurate measurement is possible.

  Further, according to the invention of claim 4, since the target is displayed on the bowl surface by an optical image which is an image and is not a substance, the target is not blurred due to dirt or the like. Can be easily displayed on any toilet.

  Furthermore, according to the invention described in claim 5, since the subject can set the target at the urination position suitable for himself, the recognition error of the urine flow collision position is reduced, and as a result, the temperature measurement region is appropriate. Therefore, the urine temperature can be measured with high accuracy.

It is a block diagram which shows the whole structure of the urine temperature measuring apparatus which concerns on this embodiment. It is a figure which shows the structure of an infrared rays light-receiving part. It is explanatory drawing explaining the light-receiving area | region of an infrared rays light-receiving part. It is an external appearance perspective view of a remote control device. It is a partial sectional view of a toilet body. It is a top view which shows the expansion | deployment urine flow area | region formed on a bowl surface. FIG. 8 is an R view in FIG. 7 showing the relationship between the temperature-detected urine flow region and the temperature-detected region in the developed urine flow region. It is a flowchart which shows the operation | movement flow of a urine temperature measurement process. It is a flowchart which shows the procedure of the urine temperature measurement process routine of the operation | movement flow in FIG.

  When measuring the temperature of urine with high accuracy without contact using infrared rays emitted by urine, to accurately measure the temperature without contact with urination trajectory until urination reaches the bowl surface, As described above, the urine temperature measuring means requires a complicated configuration.

Therefore, according to our preliminary experiment, the urine excreted by the subject is around the collision position (hereinafter, the position of the bowl surface where the urine collides is also referred to as the “urine flow collision position”) after colliding with the bowl surface. A urinary flow region spreading in a film shape (hereinafter, this urinary flow region spreading in a film shape is also referred to as a “development urinary flow region”) is formed in a specific region closer to the urine flow collision position in the developed urinary flow region. It was confirmed that the urine maintained a temperature as close as possible to the temperature of the urine at the position immediately after being released from the urination port (hereinafter, this temperature is also referred to as “urine temperature”).

  In this specific area, urine that has not been cooled by the atmosphere in the urine flow path until then appears one after another on the surface due to the collision, and it is immediately after the collision, so it is affected by cooling due to heat conduction to the toilet. This is probably because the surface temperature state with a very narrow temperature distribution is formed as a whole region, and has a sufficiently large area compared to the temperature measurement region of the urine temperature measuring means in the present invention. doing. Hereinafter, this specific region having a temperature distribution range very close to this urine temperature is referred to as “thermometric urine flow region” in the present invention.

  Therefore, in the urine temperature measuring device according to the present invention, the temperature measurement region having a predetermined area is set within the temperature measurement urine flow region having the predetermined temperature distribution range, thereby expanding the observation target region and urine. The reliable temperature measurement of the temperature measuring means can be realized.

  In addition, as for the position and shape on the bowl surface where this thermometric urine flow region is formed, the degree of change due to the difference in the subject when sitting on the toilet bowl was confirmed in another preliminary experiment. The position and shape on the surface differ depending on the subject to a degree that cannot be ignored for the size of the temperature measurement area, but the position and shape of the temperature measurement urine flow area with respect to the urine flow collision position at each position are almost constant. It was found that there was a correspondence.

  That is, it was confirmed that the position and shape of the thermometric urine flow region on the bowl surface can be estimated in advance if the urine flow collision position on the bowl surface during urination of the subject is known. This is because, when sitting on the toilet seat of a Western-style toilet as in the present invention, the position of the urination port of the subject is limited to a relatively narrow range by the toilet seat, and the position of this urination port This is probably because the shape of the bowl surface of the toilet bowl is relatively limited.

  Therefore, the urine temperature measuring device according to the present invention is provided with the urine flow collision position recognition means to obtain the urine flow collision position, and by setting the temperature measurement region of the urine temperature measurement means based on the urine flow collision position, The temperature measurement area of the urine temperature measuring means can be surely positioned within the temperature measurement urine flow area.

  As described above, the urine temperature measuring device according to the present invention includes a temperature measuring element that receives infrared rays radiated from a temperature measurement region having a predetermined area and measures the temperature in the temperature measurement region. A urine temperature measuring means for measuring the temperature of the urine excreted in a non-contact manner, and a Western-style toilet having a bowl surface for receiving the urine excreted by the subject, and a position where the urine hits the bowl surface. Urine flow collision position recognition means for recognizing as a urine flow collision position, and temperature detection area position setting means for setting the position of the temperature detection area, the temperature detection area position setting means based on the urine flow collision position An area is formed around the urine flow collision position, and is set in a thermometric urine flow area having a predetermined temperature distribution range.

  As a result, it has become possible to achieve a high level of measurement, that is, measuring the urine temperature very close to the body temperature with high accuracy.

  Here, since the urine colliding with the bowl surface flows downward more due to the action of gravity, the temperature-detected urine flow region is formed most widely on the lower side than the urine flow collision position. Therefore, it is preferable that the temperature detection region is set to a temperature detection urine flow region at a position below the urine flow collision position.

  In other words, by setting the temperature measurement region at a position below the urine flow collision position, even if the urine flow collision position changes during the measurement and the position of the temperature measurement urine flow region moves slightly, the temperature measurement region does not change. Since the state included in the region can be maintained, stable urine temperature can be measured in addition to high accuracy.

  As an example of the urine flow collision position recognizing means, an image recognition apparatus (not shown) used for detecting the position of an object in other fields can be applied. Then, the image recognition device may be installed to take a picture of the urine flow in the bowl, and the position detected by performing normal processing may be set as the urine flow collision position.

  However, since the above-described image recognition device is an advanced device, the urine temperature measuring device itself is expected to be expensive. Therefore, in the urine temperature measuring device 1 in the present embodiment, the method described below is adopted for setting the urine flow collision position in order to have a simpler configuration.

  That is, as described above, the urine flow collision position differs depending on the subject in a normal urination state even when seated on the toilet of the present invention, so that it cannot be ignored to measure the urine temperature with high accuracy. In view of this, it has been considered that the urine flow collision position can be kept within a certain range by providing a mark on the bowl surface as a guide for the urination position and adjusting the urination position on the subject side.

  Therefore, when a preliminary test was performed on this as well, in the state of sitting on the toilet, it is possible to keep the urine flow collision position within a certain range by adjusting the urination position on the subject side using the target as a guide. I was able to confirm. Furthermore, it was also confirmed that the range of the thermometric urine flow region formed below the urine flow collision position at this time is sufficient to ensure the range of the thermometric region set based on the target position.

  That is, as long as the size of the temperature measurement region is set appropriately, the urine temperature measurement of the present invention based on the urine flow collision position is sufficiently accurate even if the target position is regarded as the collision position instead of the actual collision position. It was confirmed that it was possible.

  Therefore, in the urine temperature measurement device according to the present embodiment described below, to which the present invention is preferably applied, a target serving as a measure of the urination position of the subject is set on the bowl surface, and the urine flow collision position is based on the target position. Is determined.

  Further, when the infrared light receiving unit 44 of the urine temperature measuring device 1 is performing a measurement operation, the toilet function unit 19 invalidates the instruction signal even if the sanitary washing switch 54 or the local drying switch 55 of the remote control device 11 is operated. I try to handle it. This is considered as a preventive measure for these operations to adversely affect the urine temperature measurement.

The measurement control unit 41 includes a microcomputer including a CPU, a ROM, a RAM, and the like. Various programs are stored in the ROM, and various information such as operation control of various means of the urine temperature measurement device 1 and measurement results are stored. The memory etc. are performed.

  Note that the measurement control unit 41 in the present embodiment validates the measurement operation start instruction from the individual switch 51 as the operation start instruction means only while the seating sensor detects the sitting state. That is, when the subject P is not seated on the toilet seat body 15, the urine temperature cannot be measured, and for example, measurement in a male standing position where accurate measurement cannot be performed is prevented.

  Hereinafter, the functions of the measurement control unit 41 are the urine temperature calculation unit 47 constituting the urine temperature calculation unit, the urine flow collision position recognition unit 45 constituting the urine flow collision position recognition unit, and the temperature measurement constituting the temperature measurement region position setting unit. A description will be given separately for each function of the region position setting unit 46 and the target position setting unit 71 constituting the target position adjusting means.

  The target position setting unit 71 controls the target position moving unit 58 to set a target H, which is a measure of the urination position when the subject urinates, to a predetermined position on the bowl surface B.

  In addition, although this predetermined position is set for each subject in the present embodiment, the target position setting unit 71 acquires the position used when the subject P first uses the urine temperature measuring device 1. Is initially set as the target position P-3.

  That is, the target position setting unit 71 performs urination by the subject P selecting any individual switch 51 and appropriately operating the adjustment switch 57 to set the target position set at the common position to his / her urination position. The position when the target is moved and the series of urine temperature measurement is completed is stored as the optimum target position of the subject P.

  The urine flow collision position recognition unit 45 recognizes the position where the urine excreted by the subject hits the bowl surface B as the urine flow collision position P-2 (see FIG. 1) in the present invention. The recognition of the urine flow collision position may be obtained and recognized by providing the above-described urine flow collision position detection means for physically detecting the position where the urine actually collides with the bowl surface B.

We regard it as P-2 and recognize it.

  Since the target position P-3 is managed by the target position setting unit 71 as described above, setting information of the target position can be easily acquired as internal information of the urine temperature measuring device 1 with such a configuration. . Therefore, in this embodiment, since the urine flow collision position recognition means is simplified, the entire apparatus can be created at low cost.

  The temperature detection region position setting unit 46 is for setting the position of the temperature detection region S that is a light receiving range on the bowl surface B where the infrared light receiving unit 44 receives infrared rays and performs electrical output.

You may make it calculate urine temperature by going.

(Details of the main body measuring unit 40)
Next, details of the above-described infrared light receiving unit 44 forming the main body measurement unit 40 will be described.

FIG. 5 is an explanatory diagram showing the optical relationship between the light receiving element portion 69 and the temperature measuring region S of the present invention.

  As shown in FIG. 4, the infrared light receiving unit 44 includes a plurality of temperature measuring elements 61 that receive infrared rays radiated from the surface of the object according to the temperature of the object and output them as electrical signals vertically and horizontally. The temperature measuring element group 62 to be the light receiving element portion 69 formed in this manner is provided.

  In the present embodiment, as the temperature measuring element group 62, a thermopile element in which a plurality of thermopile elements connected to a large number of thermocouples that output heat generated by receiving infrared rays as electromotive force is collectively packaged and integrated.

  As described above, in the present embodiment, the infrared light flux from the temperature measurement region S is configured to be shared by the temperature measuring elements 61 which are units constituting the temperature measuring element group 62. Therefore, if a region of any one of the plurality of temperature measuring elements 61 in the temperature measurement region S is a unit temperature measurement region Sx, the temperature measurement region S is a combination of the unit temperature measurement regions Sx. Become.

  Accurate temperature measurement is possible as long as the entire unit temperature detection region Sx of at least one of the plurality of temperature measuring elements is within the object to be measured. In this embodiment, the temperature resolution of a single element is reduced. A wider range of temperature measurement can be obtained by maintaining.

  With the configuration as described above, each temperature measuring element 61 generates an output signal corresponding to the infrared energy of the region in charge of the received map, which is sequentially taken out by the scanning means 66, and the temperature of the temperature measuring element group 62 itself. Along with the output signal of the reference temperature element 64 for measuring the value, the signal is input to the measurement control unit 41 through the A / D conversion means 68. Then, in the urine temperature calculation unit 47 that constitutes the measurement control unit 41 to which such a signal is input, after correction by the reference temperature and emissivity, the output signal of each temperature measuring element is converted into temperature information.

  In addition, in this embodiment, since the obtained temperature information employs the temperature measuring element group as the temperature measuring element, a plurality of temperature information for each temperature measuring element is obtained.

  Further, in the present embodiment, the plurality of temperature information is not focused on the infrared light from the temperature measurement region S but is formed as a mapping on these temperature measuring element groups. It becomes two-dimensional temperature information corresponding to the arrangement of each temperature measuring element. Therefore, it is possible to know the temperature distribution state in the temperature measuring region S or to display it visually.

(Details of the target projection unit 50)
Next, a specific configuration of the target projection unit 50 that similarly forms the main body measurement unit 40 will be described.
The urine temperature measuring device 1 according to the present embodiment includes a target projection unit 50 that displays the target H at the target position P-3 on the bowl surface B. Examples of the target projection unit 50 include a unit that projects a light image by irradiating laser light from a predetermined light image irradiation port using a light image generation unit such as a semiconductor laser.

  And the test position P-3 of this target H which is a target position in this invention can make the test subject P move to arbitrary positions. That is, the target projection unit 50 can move the projection position of the target H on the toilet bowl surface by moving the optical unit 63 to change the light projection axis of the target projection unit 50, for example. A position moving unit 58 is provided.

  In addition, although the arrangement | positioning position in the apparatus main body 10 of the target projection part 50 is not limited, in this embodiment, the target projection part 50 is arrange | positioned in the front end side of the casing 14, as shown in FIG.

  Further, as shown in FIG. 2, the target projection unit 50 is provided at a position that is biased to the right with respect to the discharge port of the sanitary washing water nozzle of the toilet function unit 19. Thereby, discharge of the washing water from the sanitary washing water nozzle is not disturbed.

  In this way, by disposing the target projection unit 50 at a position close to the center line on the front end side in the casing 14, the optical image is directed from the target projection unit 50 toward the region where the urination position is on the front side of the bowl portion 17. Since the projection can be performed at an angle closer to vertical, the target H can be displayed on the bowl surface B on the front side of the bowl portion 17 in an easy-to-view state by a light image with less distortion.

  Further, the light image that becomes the target H on the bowl surface B is merely an image and is not an entity, so it does not become dirty and unclear, and various toilets in which the urine temperature measuring device 1 is assembled. Can be easily marked.

(Details of remote control device)
FIG. 6 shows an external perspective view of the remote control device 11. As shown in the figure, the remote control device 11 includes an individual switch 51 operated by the subject P when starting the urine temperature measurement in the apparatus main body 10 and a subject when the urine temperature measurement is finished in the urine temperature measurement unit 40. A measurement end switch 52 operated by P, a toilet cleaning switch 53 operated by the subject P when cleaning the bowl portion 17 of the toilet main body 12 after defecation, a sanitary cleaning switch 54 instructing the operation of the sanitary cleaning device, A change switch 57 for changing the target position and a remote control display unit 32 for displaying various information such as measurement results and measurement conditions are provided.

  Here, the urine temperature to be measured by the present invention is used not only as temporary physical information but also as health management information such as management of a woman's menstrual cycle. Accumulation in units becomes important. Therefore, in the case of a form used by a plurality of subjects, a function for personally identifying the plurality of subjects is required.

  As an individual identification means for that purpose, an existing method such as an ID card can be adopted. However, in the present embodiment, a plurality of switches are provided, and each switch is assigned to a specific subject. It is configured to perform identification.

  That is, the individual urine temperature measurement switch 51 functions as a measurement start means for starting urine temperature measurement in the present embodiment, but four buttons are assumed for use in an individual home as shown in the figure. For example, it is assigned to each individual constituting the family and can be used as a personal identification means.

  The individual urine temperature measurement switch 51 composed of these four buttons is assigned a dedicated storage area for each button, and the obtained measurement result is the measurement result of the subject assigned to the selected button. Is stored in this dedicated storage area. That is, for example, when the urine temperature is measured by pressing the “1” button, the obtained result is stored in a storage area dedicated to the “1” button.

  Thus, the subject PA presses the assigned “1” button to perform urine temperature measurement, so that the subject PA is placed on the storage area of the storage medium assigned to the “1” button. Only urine temperature measurement results can be accumulated.

  Further, by operating each button of the individual switch 51, the individual urine temperature measurement result stored in this dedicated storage area is read out, and the history is graphed as shown in the figure, and the remote control display unit 32 can be displayed.

  In this embodiment, the personal identification function of the individual switch 51 is used not only to manage measurement results but also to manage other information that needs to be managed on an individual basis.

  That is, in the present embodiment, the optical target H that is the target of the urination position is displayed on the bowl surface to the subject. The display position of the target H is assigned to the individual switch 51 for each subject. When the subject P selects and depresses the individual switch 51 at the start of measurement, the target H is displayed at the target position assigned to the switch.

  Specifically, when the individual urine temperature measurement switch 51 is operated at the start of measurement, the target position setting unit 71 is assigned according to the individual urine temperature measurement switch 51 and stored in the storage medium. The target position P-3 is obtained by selecting the target position of the target, and the target position projection unit 50 is moved by driving an actuator such as an electric motor (not shown), so that the target H projected on the bowl surface B is personalized. The target position P-3 corresponding to the urine temperature measurement switch 51 is set.

  Next, a method for assigning and registering the target position at the time of first use to the individual urine temperature measurement switch 51 will be specifically described.

  When the subject P selects any individual switch 51, the target H is displayed at a predetermined initial position. Thereafter, urination is started and the change switch 57 is operated to make the display position of the target H coincide with the collision position of the urine as much as possible. Thereafter, when the urine temperature measurement is finished, the position at that time is assigned to the selected individual switch 51 and stored as the target position P-3 of the subject P. From the next use, the target is displayed at the registered position.

  In the present embodiment, the change switch 57 has a function as target position adjusting means. That is, this target position is a position set and memorized by the subject himself, and in this embodiment, he / she urinates by sitting on the toilet seat. Although this is relatively simple, it may still occur that the urine flow collision position shifts to a position deviated from the target position depending on the position and posture of sitting on the toilet seat.

  That is, when the urine flow collision position deviates from the target position during measurement, the subject P selects and pushes the button (see FIG. 6) in the direction in which the change switch 57 is to be moved, and sets the target position to the urine. Change to match the flow collision position. At this time, when a series of measurements are completed in this state, the target position setting unit 71 updates the personal data with the position at that time as the target position P-3.

  Thus, the subject P can set the target H at a position that seems to be optimal for the subject P by using the change switch 57, so that the target position P-3 and the actual urine flow collision position P-2 are set. Since the deviation is reduced and the temperature of the temperature-detected urine flow region U can be reliably measured, the urine temperature (body temperature) can be accurately measured.

  In the present embodiment, as shown in the figure, the change switch 57 is configured such that the position adjustment can be adjusted only in the front-rear direction.

  Further, when the individual switch 51 is pressed, a password may be requested when functioning as an operation start instruction means or when displaying a urine temperature measurement history. With this configuration, it is possible to prevent leakage of personal information and protect privacy. In order to input a password, a separate numeric key switch may be provided, or a touch panel may be provided on the remote control display unit 32.

  In the present embodiment, the display unit 32 not only displays the numerical value of the measurement result and the history graph as described above, but also displays the current target position P-3 relative to the target position changeable range as shown in the figure. Thus, the test subject is informed of the measurement status.

(About the specific setting method of the temperature detection area S)
A method for setting the temperature measurement region S in the urine temperature measurement device 1 according to the present embodiment will be described.

  FIG. 7 is a partial cross-sectional view of the toilet main body 12 constituting the urine temperature measuring device 1 according to the present embodiment. FIG. 8 shows a developed urine flow region formed on the bowl surface B of the toilet main body 12. FIG. 9 is a plan view showing the target H, and FIG. 9 is a view taken in the direction of arrow R in FIG. 7 for showing the temperature-detected urine flow region in the developed urine flow region, and the position of the developed urine flow region formed on the bowl surface The state in which is fluctuated is also shown by a one-dot chain line.

  In the urine temperature measuring apparatus 1, when the subject sits on the toilet seat and urinates while aiming at the target H projected on a predetermined position of the bowl surface B, the urine draws a parabola as shown in FIG. It falls into the vicinity and collides. Then, as shown in FIG. 8, the urine colliding with the bowl surface B spreads toward the stored water W while spreading around the urine flow collision position P-2 with a spread corresponding to the amount of urination. Go. In the figure, T indicates a developed urine flow region formed around the urine flow collision position P-2 on the bowl surface B.

  Here, as shown in FIG. 9, the specific area indicated by U in the developed urine flow area T is uniform at the temperature of urine immediately after urination, that is, at a temperature very close to the urine temperature in the present invention, as described above. It was confirmed that the temperature distribution was shown, and the position and shape thereof had a good correlation with the urine flow collision position P-2 (hereinafter, this specific area is referred to as a thermometric urine flow area U).

  In the present embodiment, as described above, the temperature measuring element unit 44 including the plurality of temperature measuring elements 61 is employed in the infrared light receiving unit, and the temperature measuring region S is connected to the plurality of temperature measuring elements 61. Since the assigned configuration is adopted, if at least one of the plurality of temperature measurement regions is included in the temperature measurement urine flow region U, accurate measurement is possible.

  The size of the temperature-detected urine flow region U is about 50 mm × 70 mm in a certain experimental example when the temperature distribution is within a range of ± 0.1 ° C. necessary for urine temperature measurement, and is adopted in this embodiment. Stable measurement is performed with respect to the size (20/8 mm × 20/8 mm) of the temperature measuring area per element of the temperature measuring area S (20 mm × 20 mm) of the temperature measuring element group 62 (8 × 8 = 64 elements). It was confirmed that the area was large enough.

  Therefore, the urine temperature measuring device 1 in the present embodiment sets the temperature measurement region S for measuring the urine temperature in the temperature measurement urine flow region U on the bowl surface B based on the urine flow collision position P-2. Yes.

  In other words, various urine flow collision positions are set in advance, the position and shape in the thermometric urine flow region U formed therearound are measured, and the relationship is stored in the storage unit of the measurement control unit 41. At the time of measurement, the temperature detection position setting unit 46 recognized by the urine flow collision position recognition unit 45 sets the position of the temperature detection region S to a predetermined position in the temperature detection urine flow region U determined in advance based on the urine flow collision position P-2. Is set.

  Further, in many cases, the thermometric urine flow region U is formed in a wider range on the lower side of the urine flow collision position P-2 as shown in the drawing because of the positional relationship between the urination port P-1 and the bowl surface B. It was also found in preliminary experiments.

  Therefore, in this embodiment, as shown in FIG. 9, the temperature detection region S is set in a predetermined position within the temperature detection urine flow region U and below the urine flow collision position P-2. Since the temperature-detected urine flow region U at this position is sufficiently wide compared to the area of the temperature-detected region S, the urine flow collision position P-2 registered in advance even if the urination position or urination state of the subject P changes during urination. As long as the position of the temperature detection region S is set with reference to, the temperature measurement of the temperature detection urine flow region U can be performed stably.

  Thus, by setting the temperature measurement region S below the urine flow collision position P-2, highly accurate urine temperature measurement can be stably performed.

  In addition, even if the subject P is the same, the actual urine flow collision position is considered to often fluctuate back and forth and left and right with respect to the display position of the target H, but the reference urine flow collision position P-2 By setting the temperature measurement region S downward, the actual urine flow collision position is front, rear, left and right as shown by P′-2 with respect to the target H at the target position P-3, as shown by a one-dot chain line in FIG. Even if it is slightly displaced, the possibility that the temperature measurement region S is included in the temperature-measured urine flow region U ′ after movement is significantly increased.

Thus, even if the configuration in which the target H displayed on the subject P is aimed at and urinated and the target position P-3 is regarded as the urine flow collision position P-2 is used as the urine flow collision position recognition means, it is accurate. Urine temperature measurement can be expected.

  Thus, the urine excreted by the subject aiming at the target H spreads thinly around the urine flow collision position P-2 after colliding with the bowl surface B, and forms a thermometric urine flow region U in the developed urine flow region T. By setting the temperature detection region S while regarding the target position P-3 as the urine flow collision position P-2, the urine temperature can be reliably measured with a simple configuration.

(About urine temperature measurement procedure by urine temperature measuring device)
Next, the procedure for measuring the urine temperature of the urine temperature measuring apparatus 1 having the above-described configuration will be described with reference to the operation flowcharts shown in FIGS.
FIG. 10 is a flowchart showing the entire operation, and FIG. 11 is a flowchart showing details of the routine processing of FIG.

  First, when the subject P is seated on the toilet seat body 15 and the individual switch 51 assigned to the remote controller 11 in advance is appropriately selected and pressed, the remote controller controller 31 of the remote controller 11 causes the urine temperature measurement switch to be selected. The ON signal and the selected switch number are detected (step S11).

  The remote controller 31 that has detected the ON signal generates an instruction signal for starting the measurement operation by the urine temperature measurement unit 40, that is, a measurement operation start instruction signal, and the apparatus main body 10 through the remote controller communication unit 34. Is transmitted to the measurement control unit 41 (step S12). The measurement operation start instruction signal also includes a switch number signal as a subject specifying signal (information including this signal for specifying the subject is also referred to as “subject specifying information” below).

  Next, when the target position setting unit 71 of the measurement control unit 41 receives the measurement operation start instruction signal via the main body communication unit 42, the target position setting unit 71 drives the actuator of the target display unit 50 to include the target in the measurement operation start instruction signal. In response to the test subject specifying signal, the individual switch 51 moves to the position registered as the target position P-3 at the first use (step S13).

  The urine flow collision position recognition unit 45 stores the target position P-3 set here as the urine flow collision position P-2, and the temperature detection region position setting unit 46 drives the temperature detection region moving unit to The temperature detection region S is set at a position below a predetermined distance from the urine flow collision position P-2 (step S14).

  Thereafter, the subject P starts to urinate, but the change switch 57 is operated as necessary to finely adjust the target position. Then, a position movement signal is sent from the remote control device 11 to the apparatus main body unit 20, and the target position setting unit 71 (measurement control unit 41) sends a position signal corresponding to the operation amount of the change switch 57 to the target display unit 50 and targets. The position is finely adjusted, and the changed target position is updated and stored as the target position P-3 of the subject P (step S15).

  When the setting of the temperature measurement region S is completed, the measurement control unit 41 starts control of the urine temperature measurement unit 40 and executes a urine temperature measurement process (step S16). The urine temperature measurement process will be described in detail below as a urine temperature measurement process routine with reference to FIG.

  In the urine temperature measurement processing routine, as shown in FIG. 11, first, the urine temperature calculation unit 47 of the measurement control unit 41 acquires the measurement temperature of each element of the thermopile (step S21). That is, a set obtained by scanning the output signals from the temperature measuring elements 61 of the temperature measuring element group 62 having an 8 × 8 configuration based on the infrared rays received from the temperature measuring area S in the infrared light receiving unit 44. The operation of acquiring the two-dimensional measured temperature information as one frame information is repeated until a predetermined number of times.

  Next, when the urine temperature calculation unit 47 determines that the acquired number of frames has reached the preset number of times (step S22: Yes), the urine temperature calculation unit 47 calculates the temperature information for each temperature measuring element 61 in the temperature measuring element group 62. An averaging process is performed to calculate the average measured temperature of each temperature measuring element 61 in a preset number of frames (step S23).

  In the present embodiment, the average measured temperature is calculated for all the temperature measuring elements 61 in the temperature measuring element group 62 based on the acquired data for 50 frames. In this way, by calculating the average measured temperature of each temperature measuring element 61 in a preset number of frames, the amount of influence on the measurement value due to the noise of the detection signal generally generated for each temperature measuring element 61 is reduced. Can do.

  When the prescribed number of times has not been reached (step S22: No), the process returns to step S21.

  Next, the measurement control unit 41 extracts the maximum value from the average measured temperatures of the temperature measuring elements 61 in a preset number of frames, and stores this in the storage medium as the urine temperature measured value at that time. (Step S24).

  That is, the measurement control unit 41 calculates an average measurement temperature for each element from the output signals of the plurality of temperature measurement elements 61 that receive infrared rays, and calculates the highest value among the average measurement temperatures as the urine temperature measurement unit 40. The urine temperature measurement value is processed. Since the urine temperature is higher than the ambient temperature in the normal measurement environment, the urine temperature may decrease from the temperature immediately after urination due to the cooling phenomenon, but it will not rise. By using the maximum value among the plurality of temperatures obtained for each element as a measured value of the temperature of the urine in the thermometric urine flow region U, a measured value closer to the urine temperature can be obtained.

  In this embodiment, as described above, since the infrared light receiving unit is composed of a plurality of temperature measuring elements, a method of selecting one of a plurality of obtained temperature data is adopted. If at least one unit temperature detection region Sx is included in the above-described temperature detection urine flow region U, the temperature measurement of urine in the temperature detection urine flow region U is correctly performed.

  Next, the measurement control unit 41 determines whether or not the measurement end switch 52 in the remote control operation unit 33 of the remote control device 11 has been pressed (step S25).

  As a result, when it is determined that the measurement end switch is not pressed (step S25: No), the measurement control unit 41 returns the process to step S22.

  On the other hand, if it is determined that the measurement end switch has been pressed (step S25: Yes), the measurement control unit 41 at each time point from when the urine temperature measurement switch is pressed until the measurement end switch is pressed. The maximum value of the recorded values stored in the storage medium as the urine temperature measurement value is extracted and determined as the urine temperature measurement value in one urination action, and the urine temperature measurement value is stored in the specified subject The information is stored in the storage medium in association with the information (step S26), and the urine temperature measurement process is terminated.

  When the urine temperature measurement process is completed, the measurement control unit 41 displays on the remote control display unit 32 of the remote control device 11 based on the obtained urine temperature measurement result information and the past measurement information of the subject corresponding to the subject specifying information. Measurement result display data to be created is created (step S17).

  Next, the measurement control unit 41 transmits information related to the measurement result including the created measurement result display data (hereinafter, this information is also referred to as “urine temperature measurement result information”) via the main body communication unit 42. 11 to the remote control unit 31 (step S18).

  In addition, as another example of urine temperature measurement result information, for example, in a certain measurement, when the urine flow collision position is significantly shifted or the urine temperature measurement is not performed normally because urination has been completed in a short time There is alarm information indicating that the urine temperature measurement was not performed normally.

  When receiving the urine temperature measurement result information via the remote control communication unit 34, the remote control unit 31 displays the urine temperature measurement result on the remote control display unit 32 (step S19).

  In this case, if information indicating that the urine temperature measurement was not performed is included, for example, “The urine temperature measurement was not performed normally, so there is an error in the measurement results.” Display is performed on the remote control display unit 32 to inform the subject that attention should be paid.

  Thereafter, the measurement control unit 41 of the apparatus main body unit 10 and the remote control unit 31 of the remote control device 11 perform a predetermined measurement preparation operation necessary for the next urine temperature measurement, and end a series of urine temperature measurements.

  In the present embodiment, the remote controller 11 is provided with the remote controller display 32, the remote controller operating unit 33, etc. in order to perform the operation and display related to the urine temperature measurement. Although it is set as the structure which functions as the urine temperature measuring apparatus 1 by communicating with the apparatus main body part 10, it replaces with the remote control display part 32 and the remote control operation part 33 of the remote control apparatus 11, and an operation display part etc. are provided on the apparatus main body 10. It is good also as a structure which provides.

  By the way, the urine temperature measuring apparatus 1 described above is configured such that the urine temperature measuring unit 20 is integrated in advance in a Western-style toilet. However, the urine temperature measuring unit 20 may be provided in a separate housing from the western toilet and can be retrofitted to an existing western toilet.

  In the present embodiment, the temperature measuring element group including a plurality of temperature measuring elements is used as the light receiving element included in the infrared light receiving unit 44. However, at least a signal corresponding to the temperature in the temperature detection region can be output. Therefore, a light receiving element including a single temperature measuring element may be used.

  Moreover, description of each embodiment mentioned above is an example of this invention, and this invention is not limited to the above-mentioned embodiment. For this reason, it is a matter of course that various modifications other than the above-described embodiments can be made according to the design and the like as long as they do not depart from the technical idea according to the present invention.
