Description

[Technical Field]

[0001] The present invention relates to a flush toilet apparatus, and more particularly to a flush toilet apparatus that measures biological information from a user's excrement. [Background technology]

[0002] Conventionally, flush toilet devices that measure biometric information from a user's excrement are known, as described in Patent Document 1. In such flush toilet devices, personal authentication is performed after the user sits on the toilet seat, and preparations for measuring biometric information begin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-168952 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the flush toilet device described in Patent Document 1 has the problem that personal authentication is performed and preparation for measuring biometric information begins after the user sits on the toilet seat, so the user must remain seated while waiting for measurement preparation to be completed. On the other hand, it is possible to perform personal authentication and start preparations for biometric information measurement simultaneously when a user enters the restroom. This has the advantage that measurement preparations are complete when the user sits on the toilet seat, allowing biometric information measurement to begin immediately. However, to perform personal authentication simultaneously with a user's entry, the detection range for personal authentication must be expanded to the entire restroom. If the detection range for personal authentication is set to the entire restroom, there is a risk that a user using an adjacent restroom may be erroneously authenticated. Furthermore, because metal frames are used in the partition walls of restrooms, expanding the detection range for personal authentication to the entire restroom could result in the metal frames functioning as antennas and potentially causing false positives in personal authentication. Furthermore, when a user wearing a cardiac pacemaker uses the restroom, there is a risk of noise interference to the cardiac pacemaker.

[0005] Therefore, the present invention was made to solve the above-mentioned conventional problems, and aims to provide a flush toilet device that prevents personal authentication from being performed erroneously, reduces the risk of noise to cardiac pacemakers, etc., and can begin measuring biometric information immediately when the user sits on the toilet seat. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention provides a flush toilet apparatus that measures biometric information from a user's excrement, comprising: a bowl portion that receives the user's excrement; a drain trap pipe that is connected below the bowl portion and forms pooled water within the bowl portion; a biometric information measuring device that measures biometric information from excrement excreted in the bowl portion; a personal authentication device that performs personal authentication of the user; a first detection unit that detects whether a user is present within a first detection range; a second detection unit that detects personal information of a user who is present within a second detection range; and a control unit that controls the biometric information measuring device and the personal authentication device based on the detection results of the first detection unit and the second detection unit, wherein the first detection range is set to be wider than the second detection range, and the control unit operates the biometric information measuring device to prepare for measurement when the first detection unit detects a user within the first detection range, and operates the personal authentication device to perform personal authentication when the second detection unit detects personal information of a user within the second detection range.

[0007] In the present invention configured as described above, the first detection range is set to a range wider than the second detection range, and the control unit activates the biometric information measurement device to perform measurement preparation when the first detection unit detects a user within the first detection range, thereby completing measurement preparation when the user sits on the toilet seat. Furthermore, the second detection range is set to a range narrower than the first detection range, and the control unit activates the personal authentication device to perform personal authentication when the second detection unit detects personal information of a user within the second detection range, thereby preventing erroneous personal authentication of a user using an adjacent toilet room. Furthermore, because the second detection range is set to a relatively narrow range, the risk of noise to cardiac pacemakers and the like can be reduced. Therefore, erroneous personal authentication is prevented, the risk of noise to cardiac pacemakers and the like is reduced, and measurement of biometric information can be started immediately when the user sits on the toilet seat.

[0008] In the present invention, preferably, the first detection range is set to extend from the flush toilet device to the entrance of the toilet room, and the second detection range is set in the vicinity of the flush toilet device. With the present invention configured in this way, the first detection range is set to extend from the flush toilet device to the entrance of the toilet room, so measurement preparation can be carried out as soon as the user enters, and the second detection range is set near the flush toilet device, so it is possible to reliably prevent personal authentication from being performed erroneously. It is also possible to reliably reduce the risk of noise to cardiac pacemakers and the like.

[0009] Furthermore, in the present invention, it is preferable that the device further comprises a third detection unit for detecting that a user is seated on the toilet seat of the flush toilet device, and when the third detection unit detects that the user is seated, the control unit activates the personal authentication device to perform personal authentication. The present invention configured in this manner further includes a third detection unit for detecting that a user is seated on the toilet seat of the flush toilet device, and when the third detection unit detects that a user is seated, the control unit activates the personal authentication device to perform personal authentication, thereby reliably preventing personal authentication from being performed erroneously.

[0010] In the present invention, the second detection range is preferably set to an area to the right of the left-right centre of the flush toilet apparatus, as seen by a user seated on the toilet seat. With the present invention configured in this way, the second detection range is set to the right of the center in the left-right direction of the flush toilet device as seen by a user seated on the toilet seat, so when a user sits on the toilet seat, it is possible to detect personal information on a band attached to the user's right wrist. Also, when a user wearing a cardiac pacemaker sits on the toilet seat, the risk of noise to the cardiac pacemaker can be reduced.

[0011] Additionally, in the present invention, the second detection range preferably has a right-side detection range, which is an area to the right of the left-right center of the flush toilet device, and a left-side detection range, which is an area to the left of the left-right center of the flush toilet device, and if the user's personal information is not detected within the right-side detection range, the control unit activates the second detection unit to detect the user's personal information within the left-side detection range. In the present invention configured in this manner, the second detection range comprises a right-side detection range, which is the area to the right of the left-right center of the flush toilet device, and a left-side detection range, which is the area to the left of the left-right center of the flush toilet device; if the user's personal information is not detected within the right-side detection range, the control unit activates the second detection unit to detect the user's personal information within the left-side detection range, so that when the user defecates while standing, the personal information on the band attached to the user's right wrist can be detected. [Effects of the Invention]

[0012] The flush toilet device of the present invention prevents erroneous personal authentication and reduces the risk of noise to cardiac pacemakers and the like, and can begin measuring biometric information immediately when the user sits on the toilet seat. [Brief explanation of the drawings]

[Figure 5] FIG. 2 is a diagram showing the operational flow of a flush toilet apparatus according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] A flush toilet apparatus 1 according to an embodiment of the present invention will now be described with reference to the accompanying drawings. First, the overall structure of a flush toilet apparatus 1 according to an embodiment of the present invention will be explained using Figs. 1 to 3. FIG. 1 is a perspective view of a flush toilet apparatus 1 according to an embodiment of the present invention, FIG. 2 is a side cross-sectional view of a flush toilet apparatus 1 according to an embodiment of the present invention, and FIG. 3 is a block diagram showing the configuration of a flush toilet apparatus 1 according to an embodiment of the present invention. In this specification, the front will be referred to as "front", the rear as "rear", the left as "left", and the right as "right" when viewed from the perspective of a user seated on the toilet seat.

[0015] As shown in Figure 1, a flush toilet apparatus 1 is installed on the floor of a toilet room R. The toilet room R is a private space formed by a partition wall. The flush toilet apparatus 1 comprises a ceramic toilet body 2, a toilet seat apparatus 4 placed on the top surface of the toilet body 2, a biometric information measuring device 6 for measuring the biometric information of the user, and a personal authentication device 8 for personal authentication of the user. In this embodiment, the biometric information measuring device 6 and the personal authentication device 8 are configured separately, but they may also be configured as an integrated unit.

[0016] As shown in Figure 2, the toilet body 2 is formed with a bowl portion 3 for receiving waste, a drain trap pipe 7 provided at the bottom of the bowl portion 3 for discharging waste by siphon action, a rim spout 9 for rim water spouting, a rim water conduit 10 for supplying flushing water to the rim spout 9, a jet spout 12 for jet water spouting, and a jet water conduit 14 for supplying flushing water to the jet spout 12.

[0017] The bowl part 3 comprises a bowl-shaped waste receiving surface 15, a rim part 18 formed along the upper edge of the bowl part 3, and a basin part 20 formed below the waste receiving surface 15 and in which pooled water W is formed.

[0018] The drain trap pipe 7 has an inlet 7a, an ascending pipe 7b extending upward from the inlet 7a, a descending pipe 7c extending downward from the ascending pipe 7b, and a top 7d located between the descending pipe 7c and the ascending pipe 7b and defining an initial water level L0 of the accumulated water. A lower end 7e of the descending pipe of the drain trap pipe 7 is connected to a drain pipe (not shown) via a drain socket 22.

[0019] The rim spout 9 is located at the rear right side in a plan view of the bowl portion 3. The rim spout 9 spouts flush water rearward, and this flush water flows down to the waste receiving surface 15 while swirling along the rim portion 18.

[0020] Jet water outlet 12 is formed below bowl portion 3. Jet water outlet 12 is directed toward inlet portion 7a of drain trap pipe line 7. Jet water outlet 12 ejects flush water toward inlet portion 7a of drain trap pipe line 7, and this flush water flows into drain trap pipe line 7, activating the siphon action.

[0021] As shown in Figure 3, flush water from a water supply source 24, such as a water line, is supplied to the toilet body 2, toilet seat device 4, and vital information measuring device 6 via a stop valve 26 and a branch fitting 28. A toilet flush valve 30 is provided upstream of the rim water conduit 10 and the jet water conduit 14 to supply flush water to the rim water conduit 10 and / or jet water conduit 14. The toilet flush valve 30 is driven by a command from a control unit 32 based on operation by the user, and flush water from the water supply source 24 is supplied to the rim water conduit 10 and / or jet water conduit 14.

[0022] As shown in Figures 1 and 3, the toilet seat device 4 comprises a main body 40, a cleaning nozzle (not shown) that is movable forward and backward from the main body 40, a toilet seat (not shown) that is rotatably attached to the main body 40, a toilet seat cover 42 that is rotatably attached to the main body so as to cover the toilet seat, a human body detection sensor 44 (first detection unit) for detecting whether a user is present in the toilet room R, a seating sensor 46 (third detection unit) for detecting whether a user is seated on the toilet seat, and a functional water discharge device 48 for discharging functional water.

[0023] The flushing nozzle is attached to the main body 40 so as to be movable forward and backward in the front-to-rear direction of the toilet body 2. The flushing nozzle sprays cleaning water from a nozzle provided at the tip, so that the private parts of the user of the toilet seat device 4 are cleaned.

[0024] The toilet seat is rotatably attached to the main body 40, and is placed on the top surface of the toilet so as to surround the bowl 3 for a user to sit on. The toilet seat cover 42 is rotatably attached to the rear of the main body 40. When the toilet seat cover 42 is closed, the main body 40 and the toilet seat are covered by the toilet seat cover 42.

[0025] The human body detection sensor 44 is an infrared sensor that detects infrared rays emitted from a user. The human body detection sensor 44 is provided on the main body 40 so as to face the entrance to the toilet room R in front (see FIG. 1). When the human body detection sensor 44 receives infrared rays reflected from the user, it is determined that the user is in the toilet room R. Note that in this embodiment, an infrared sensor is used as the human body detection sensor, but a microwave sensor or the like may be used instead.

[0026] The seat sensor 46 is a distance measurement sensor that uses infrared rays. The seat sensor 46 is mounted on the main body 40 so as to face forward (see FIG. 1). When the seat sensor 46 receives infrared rays reflected from a user, the output voltage changes depending on the distance, and it is determined that the user is seated on the toilet seat. In this embodiment, a distance measurement sensor is used as the human body detection sensor, but instead, a load sensor that detects the load applied when the user is seated on the toilet seat may be used.

[0027] The functional water discharge device 48 supplies functional water, such as hypochlorous acid water obtained by electrolysis, to the bowl portion 3. The functional water discharge device 48 is built into the main body portion 40 and is configured to discharge the functional water from the nozzle of the cleaning water nozzle. The functional water is discharged from the cleaning water nozzle, thereby sterilizing and cleaning the bowl portion 3 and the cleaning water nozzle.

[0028] As shown in FIGS. 2 and 3 , the biological information measuring device 6 includes a water level measuring conduit 50 communicating with the accumulated water W in the bowl portion 3, and a water level sensor 52 that detects the level of the accumulated water W via the water level measuring conduit 50. The water level measuring conduit 50 communicates with the bowl portion 3 and also communicates with the jet water conduit 14, with a portion of the conduit being shared with the jet water conduit 14. The biological information measuring device 6 is capable of measuring biological information such as the amount of urine excreted by the user (subject) and the urinary flow rate (amount of urine excreted per unit time) based on changes in the water level measured by the water level sensor 52 during urination and pressure measured by a pressure sensor (not shown). The biological information measuring device 6 is also disposed within a cabinet 60. A data output device 54 that outputs measurement results and the like from the biological information measuring device 6 is provided above the cabinet 60. In this embodiment, the biological information measuring device 6 has been described as a device equipped with a water level measurement pipe 50, a water level sensor 52, and a pressure sensor, but this is not limited to this and any form is acceptable as long as it can measure biological information such as urine volume and urinary flow rate.

[0029] As shown in FIG. 1, a flush start switch 34 for starting toilet flushing and a measurement start switch 36 for starting measurement of biological information are provided on the partition wall of the toilet room R.

[0030] As shown in FIGS. 1 and 3 , the personal authentication device 8 includes an RFID reader 56 (second detection unit) that contactlessly reads personal information from an IC tag carried by a user, and a personal information storage device 58 that stores personal information such as past measurement records. The RFID reader 56 transmits and receives radio waves to and from an IC tag (not shown) carried by a user to read the personal information. The RFID reader 56 is disposed inside a cabinet 60 facing forward. The IC tag is embedded in a band (not shown) attached to the user's right wrist. The personal information storage device 58 stores measured biometric information. Note that, although personal authentication is performed using the RFID reader 56 in this embodiment, this is not limiting and any form capable of personal authentication may be used.

[0031] The control unit 32 is electrically connected to the toilet flush valve 30, flush start switch 34, measurement start switch 36, toilet seat device 4, biometric information measurement device 6, and personal authentication device 8, and is capable of sending and receiving various signals. When the control unit 32 receives a flush start signal from the flush start switch 34, it executes toilet flushing based on a pre-stored flush sequence. Furthermore, when the control unit 32 receives a detection signal from the human body detection sensor 44 of the toilet seat device 4, it starts preparations for measuring biometric information. Furthermore, when the control unit 32 receives personal information from the RFID reader 56 of the personal authentication device 8, it starts personal authentication. Furthermore, when the control unit 32 receives a measurement start signal from the measurement start switch 36, it starts measuring biometric information.

[0032] Next, the detection ranges of the detection units of a flush toilet apparatus 1 according to an embodiment of the present invention will be explained using FIG. FIG. 4 is a diagram showing the detection ranges of each detection unit in a plan view of a flush toilet apparatus 1 according to an embodiment of the present invention.

[0033] 4, the first detection range A of the human body detection sensor 44 is set to be different from the second detection range B of the personal authentication device 8, and the first detection range A is set to be wider than the second detection range B. When the human body detection sensor 44 detects a user within the first detection range A, preparations for measuring biometric information are executed. Furthermore, when the personal authentication device 8 detects personal information of the user within the second detection range B, personal authentication is executed.

[0034] The length in the front-to-rear direction of the first detection range A of the human body detection sensor 44 is set to extend from the rear side of the flush toilet device 1 to the entrance 62 of the toilet room R. The width in the left-to-right direction of the first detection range A is set to be approximately the same as the left-to-right width of the toilet room R. This makes it possible to carry out preparations for measuring biological information as soon as the user enters the toilet room R.

[0035] The second detection range B of the personal authentication device 8 is set in the vicinity of the flush toilet device 1. The second detection range B is set to follow the outer edge of the toilet body 2 of the flush toilet device 1. The second detection range B is a predetermined distance away from the partition wall of the toilet room R, to prevent erroneous personal authentication of a user using an adjacent toilet room.

[0036] The second detection range B of the personal authentication device 8 comprises a right-side detection range B1, which is the area to the right of the left-right center of the flush toilet apparatus 1, and a left-side detection range B2, which is the area to the left of the left-right center of the flush toilet apparatus 1. The second detection range B is selectively set to the right-side detection range B1 or / and the left-side detection range B2. Specifically, the second detection range B is initially set to the right-side detection range B1, and if the user's personal information is not detected within the right-side detection range B1, it is changed to the left-side detection range B2. This makes it possible to narrow the second detection range B, which, for example, can reduce the risk of noise to the cardiac pacemaker when a user with a cardiac pacemaker sits on the toilet seat.

[0037] Next, the operation of the flush toilet device 1 according to this embodiment of the present invention will be explained. Figure 5 is a diagram showing the operational flow of a flush toilet apparatus 1 according to an embodiment of the present invention. In Figure 5, S represents each step.

[0038] First, in S1, the human body detection sensor 44 of the toilet seat device 4 detects whether or not a user is present within the first detection range A. When a user enters the toilet room R, the human body detection sensor 44 detects that the user is present within the first detection range A (S1; Yes). While there is no user in the toilet room R, the human body detection sensor 44 continues to detect whether or not a user is present within the first detection range A (S1; No).

[0039] In S2, upon receiving a detection signal from the human body detection sensor 44, the control unit 32 activates the toilet flush valve 30 and the biological information measurement device 6 to prepare for measuring biological information. Specifically, the control unit 32 activates the toilet flush valve 30 to perform jet water spouting, thereby discharging the accumulated water W that has accumulated in the bowl unit 3. Next, the control unit 32 activates the toilet flush valve 30 to perform rim water spouting, thereby raising the level of the accumulated water to the measurement start water level L1 (see FIG. 2). This completes preparation for measuring biological information. In this embodiment, the preparation for measurement is started automatically, but it may also be started by the user pressing the measurement start switch 36, for example.

[0040] In S3, the seat sensor 46 of the toilet seat device 4 detects whether or not the user is seated on the toilet seat. When the user sits on the toilet seat, the seat sensor 46 detects that the user is seated (S3; Yes). While the user is not seated on the toilet seat, the seat sensor 46 continues to detect whether or not the user is seated on the toilet seat (S3; No). In this embodiment, the seat sensor 46 of the toilet seat device 4 detects whether or not the user is seated on the toilet seat, but this step can be omitted as necessary.

[0041] In S4, when the RFID reader 56 of the personal authentication device 8 detects personal information on the IC tag of a user who is within the second detection range B, the control unit 32 activates the personal authentication device 8 to perform personal authentication. In the initial state, the control unit 32 sets the second detection range B to the right detection range B1 and detects the personal information on the user's IC tag. If the user is not detected within the right detection range B1, the control unit 32 changes the second detection range B to the left detection range B2 and detects the personal information on the user's IC tag. In the embodiment of the present invention, the second detection range B is set to the right detection range B1 or the left detection range B2, but it may be set to the right detection range B1 and the left detection range B2.

[0042] In S5, when the user presses the measurement start switch 36 (S5; Yes), the measurement preparation is complete and the measurement of biological information is immediately started.

[0043] In S6, the control unit 32 activates the biological information measurement device 6 to measure biological information. When the user urinates into the water in the bowl 3, the water level rises from the measurement start level L1 to the post-excretion level L2 (see FIG. 2). This change in water level becomes basic data for estimating the amount of urine excreted, and the urine volume is calculated. The measurement results of the biological information measurement device 6 are output by the data output device 54.

[0044] In S7, when the flush start switch 34 is pressed by the user (S7; Yes), toilet flushing is started.

[0045] In S8, the control unit 32 operates the toilet flush valve 30 to flush the toilet. Specifically, the toilet flush is performed in the following order: rim water spouting, jet water spouting and rim water spouting, and rim water spouting. When the toilet flush is completed, the pooled water W reaches the initial water level L0, and this operation flow ends.

[0046] Next, the effects of the flush toilet apparatus 1 according to an embodiment of the present invention will be explained.

[0047] According to the flush toilet apparatus 1 of this embodiment, the first detection range A is set to a range wider than the second detection range B, and the control unit 32 activates the vital information measurement device 6 to perform measurement preparation when the human body detection sensor 44 (first detection unit) detects a user within the first detection range A, so that measurement preparation can be completed by the time the user sits on the toilet seat. Furthermore, the second detection range B is set to a range narrower than the first detection range A, and the control unit 32 activates the personal authentication device 8 to perform personal authentication when the RFID reader 56 (second detection unit) detects personal information of a user within the second detection range B, so that erroneous personal authentication of a user using an adjacent toilet room can be prevented. Furthermore, because the second detection range B is set to a relatively narrow range, the risk of noise to cardiac pacemakers and the like can be reduced. Therefore, erroneous personal authentication is prevented, the risk of noise to cardiac pacemakers and the like is reduced, and measurement of vital information can begin immediately when the user sits on the toilet seat.

[0048] Furthermore, with the flush toilet device 1 of this embodiment, the first detection range A is set to extend from the flush toilet device 1 to the entrance 62 of the toilet room R, so measurement preparation can be carried out as soon as the user enters, and the second detection range B is set in the vicinity of the flush toilet device 1, so it is possible to reliably prevent personal authentication from being carried out erroneously. It is also possible to reliably reduce the risk of noise to cardiac pacemakers and the like.

[0049] The flush toilet device 1 of this embodiment further has a seating sensor 46 (third detection unit) for detecting that a user is seated on the toilet seat of the flush toilet device 1, and when the seating sensor 46 detects that a user is seated, the control unit 32 activates the personal authentication device 8 to perform personal authentication, thereby reliably preventing personal authentication from being performed erroneously.

[0050] Furthermore, with the flush toilet apparatus 1 of this embodiment, the second detection range B is set to the right of the center in the left-right direction of the flush toilet apparatus 1 as seen by a user seated on the toilet seat, so when a user sits on the toilet seat, it is possible to detect personal information on a band attached to the user's right wrist. Also, when a user wearing a cardiac pacemaker sits on the toilet seat, the risk of noise to the cardiac pacemaker can be reduced.

[0051] According to the flush toilet device 1 of this embodiment, the second detection range B has a right-side detection range B1, which is the area to the right of the left-right center of the flush toilet device, and a left-side detection range B2, which is the area to the left of the left-right center of the flush toilet device; if the user's personal information is not detected within the right-side detection range B1, the control unit 32 will operate the RFID reader 56 to detect the user's personal information within the left-side detection range B2, so that when the user defecates while standing, the personal information on the band attached to the user's right wrist can be detected.

[0052] The present invention is not limited to the above-described embodiments, and various changes and modifications are possible within the scope of the technical concept described in the claims. [Explanation of symbols]
