Description

[Technical field]

[0001] The disclosed embodiments relate to a toilet unit and a vital information measuring device. [Background technology]

[0002] Conventionally, toilet units have been disclosed that measure the amount of urine excreted by the user and the urinary flow rate, which is the instantaneous urine volume, by changes in the water level in the bowl of the toilet body (see, for example, Patent Document 1 and Patent Document 2). In Patent Document 1, the water level in the bowl is measured by a pressure sensor, flush water is supplied to the bowl, and the water level of the water in the bowl is adjusted. Also, in Patent Document 2, flush water is supplied to the bowl from a water replenishment tank, and the water level of the water in the bowl is adjusted. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3814827 [Patent Document 2] Patent No. 6839409 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the water level in the bowl is measured by a pressure sensor, the response of the change in the water level measured by the pressure sensor to the change in the actual water level in the bowl is slow, making it difficult to fine-tune the water level in the bowl. Also, when water is supplied to the bowl from a refill tank, the toilet unit becomes larger because the refill tank must be placed there. In addition, the presence of the refill tank means that it is unavoidable to remove the refill tank every time the toilet body is removed. In medical institutions, it is unavoidable for foreign objects such as incontinence pads and pessaries attached inside the vagina to fall out, which leads to a large increase in the maintenance burden when removing foreign objects.

[0005] An object of one aspect of the embodiment is to provide a toilet unit and a vital information measuring device that can finely adjust the water level in the bowl, reduce the maintenance burden, and enable miniaturization. [Means for solving the problem]

[0006] A toilet unit according to one aspect of the embodiment includes a toilet having a bowl for receiving waste from a user, and a biometric information measuring device for measuring the amount of urine excreted by the user. The biometric information measuring device includes an excretion information measuring unit for measuring the amount of urine excreted by the user by measuring the water level of water in the bowl, a water level adjusting unit for refilling water after the bowl has been flushed with flush water and adjusting the water level of the water in the bowl, and a water discharge volume measuring unit for measuring the amount of water discharged by the refilling. The water level adjusting unit adjusts the water level of the water in the bowl based on the amount of water discharged by the refilling measured by the water discharge volume measuring unit.

[0007] As a result, the toilet unit can accurately measure the amount of water discharged by water replenishment, for example, without providing a water replenishment tank that stores flush water for water replenishment. Therefore, the toilet unit can be made smaller. Specifically, the height of the toilet unit can be reduced. Furthermore, the toilet unit can increase the degree of freedom in installing a vital information measuring device that does not have a water replenishment tank, and for example, the vital information measuring device can be installed in a location where maintenance is easy. The toilet unit can improve the maintainability of the vital information measuring device. Furthermore, when removing a foreign object that has fallen, since there is no water replenishment tank, for example, an operator can easily remove the foreign object. In other words, the toilet unit can improve the maintainability of the toilet unit by making it easy to remove a foreign object that has been dropped. Furthermore, the toilet unit can fine-tune the water level in the bowl by adjusting the water level in the bowl based on the amount of water discharged by water replenishment measured by the water discharge amount measurement unit, and can accurately adjust the water level in the bowl.

[0008] Moreover, replenishment of water is performed by using wash water supplied directly from a wash water supply source.

[0009] This allows the toilet unit to accurately measure the amount of water discharged due to water replenishment, for example, without the need for a water replenishment tank to store flush water for replenishment. This allows the toilet unit to be made smaller. The toilet unit also allows for greater freedom in the installation of a vital information measuring device that does not have a water replenishment tank, and for example, the vital information measuring device can be installed in a location where maintenance is easy. In other words, the toilet unit can improve the maintainability of the vital information measuring device.

[0010] The toilet also has a water outlet that discharges flush water supplied directly from the flush water supply source into the bowl. The water level adjustment unit predicts the water level in the bowl after flushing based on the amount of water discharged due to water replenishment measured by the water discharge amount measurement unit.

[0011] As a result, the toilet unit can adjust the stored water level with high precision, even if the flush water volume setting is changed, without having to measure the stored water level using a pressure sensor or the like.

[0012] The toilet unit also comprises a first supply path through which flush water to be discharged into the bowl flows, and a second supply path through which flush water to be replenished flows. The discharged water volume measuring unit is provided in the second supply path.

[0013] As a result, when performing maintenance on the water discharge volume measurement unit, for example, the toilet unit can prevent the first supply path from interfering with the maintenance of the water discharge volume measurement unit. Therefore, the toilet unit can improve the ease of maintenance of the water discharge volume measurement unit.

[0014] The toilet unit also includes a water level changer that changes the water level according to the water level of the water in the bowl. A third supply passage that is connected to the water level changer is connected to the second supply passage. The discharge water volume measurement unit is provided upstream of the connection point of the third supply passage.

[0015] This allows the toilet unit to measure the amount of water discharged by refilling based on the flow rate measured by a water discharge rate measuring unit located upstream of the third supply passage branching off from the second supply passage. This allows the toilet unit to accurately adjust the water level in the bowl by refilling water.

[0016] The discharge water volume measuring unit is a flow meter.

[0017] This allows the toilet unit to accurately adjust the water level in the bowl with a simple configuration by adjusting the amount of water discharged by refilling using a flow meter to adjust the amount of water supplied.

[0018] Furthermore, the water discharge amount measuring unit is detachable.

[0019] This allows the toilet unit to improve the ease of maintenance of the water discharge volume measuring section.

[0020] The water level adjustment unit also calculates the amount of water to be replenished based on the level of water in the bowl after washing, and replenishes water so that the amount of water discharged by the replenishment measured by the water discharge amount measurement unit is the amount of water to be replenished.

[0021] This allows the toilet unit to accurately adjust the water level in the bowl after refilling with water.

[0022] The biological information measuring device includes an excretion information measuring unit, a water level adjusting unit, and a water discharge volume measuring unit. The excretion information measuring unit measures the water level of a bowl that receives the user's excrement, thereby measuring the amount of urine excreted by the user. The water level adjusting unit refills water after the bowl has been cleaned with cleaning water, and adjusts the water level of the water stored in the bowl. The water discharge volume measuring unit measures the amount of water discharged by the water refill. The water level adjusting unit adjusts the water level of the water stored in the bowl based on the amount of water discharged by the water refill measured by the water discharge volume measuring unit.

[0023] As a result, the vital information measuring device can accurately measure the amount of water discharged by water replenishment, for example, without providing a water replenishment tank that stores flush water for water replenishment. Therefore, the vital information measuring device can be made smaller, and for example, the toilet unit in which the vital information measuring device is provided can be made smaller. Specifically, the vital information measuring device can reduce the height of the toilet unit in which the vital information measuring device is provided. Furthermore, the vital information measuring device can increase the degree of freedom in installation of a vital information measuring device that does not have a water replenishment tank, and for example, the vital information measuring device can be provided in a location that makes maintenance easy. The vital information measuring device can improve maintainability. Furthermore, when removing a foreign object that has fallen, for example, since there is no water replenishment tank, an operator can easily remove the foreign object. In other words, the vital information measuring device can improve the maintainability of the toilet unit in which the vital information measuring device is provided, by making it easy to remove a foreign object that has fallen. In addition, the bioinformation measuring device can fine-tune the water level in the bowl by adjusting the water level in the bowl based on the amount of water discharged due to water replenishment measured by the water discharge amount measuring unit, thereby enabling the water level in the bowl to be accurately adjusted. Effect of the Invention

[0024] According to one aspect of the embodiment, the water level in the bowl can be finely adjusted and the size can be reduced. [Brief description of the drawings]

[0026] The toilet unit and vital information measuring device disclosed in the present application will be described in detail below with reference to the attached drawings. Note that the present invention is not limited to the embodiments shown below. It should be noted that the drawings are schematic, and the dimensional relationships and ratios of each element may differ from reality. The drawings may also include parts with different dimensional relationships and ratios.

[0027] Fig. 1 is a perspective view illustrating a toilet room in which a toilet unit 1 according to an embodiment is installed. Fig. 2 is a system configuration diagram illustrating the toilet unit 1 according to an embodiment. For ease of explanation, the sanitary washing device 3 and other components have been omitted from Fig. 2.

[0028] The toilet unit 1 is a biological information measuring unit capable of measuring the amount of urine excreted by a user. The toilet unit 1 includes a toilet 2, a sanitary flushing device 3, and a biological information measuring device 4. The toilet 2 is, for example, a wall-hung Western-style toilet. The toilet 2 may also be a floor-standing Western-style toilet.

[0029] The sanitary washing device 3 is provided above the toilet bowl 2. The sanitary washing device 3 has a casing 3a, a toilet seat 3b, and a toilet lid 3c. The sanitary washing device 3 may be configured without the toilet lid 3c, in which the torso is supported by a backrest pad. The backrest may be provided separately.

[0030] The toilet seat 3b is pivotally supported on the casing 3a so as to be freely opened and closed. The casing 3a incorporates a private parts washing function for washing the private parts of a user sitting on the toilet seat 3b.

[0031] As shown in Fig. 1, an operation unit 10 is installed on a wall of the toilet room. The operation unit 10 includes a remote control for measuring biological information and a remote control for the toilet. The remote control for the toilet includes a remote control for the sanitary cleaning device. The remote control for measuring biological information includes a measurement start switch that instructs the start of measuring urination information, a urination end switch that instructs that urination has ended, a monitor, etc.

[0032] The toilet room may be provided with a printer or the like for printing out the measurement results and the like obtained by the vital information measuring device 4. The measurement results and the like obtained by the vital information measuring device 4 may be transmitted to a terminal device such as a smartphone or a clinical electronic medical record system or the like by a communication device or the like.

[0033] The toilet 2 has a bowl 20 and a trap 21. The bowl 20 receives waste from the user. The trap 21 is connected to the lower part of the bowl 20. The toilet 2 is connected to a drainage pipe via a drain socket 28. A pool of water 22 is formed in the bowl 20 by the trap 21. The pool of water 22 acts as a water seal that blocks the gap between the drainage pipe and the bowl 20.

[0034] The toilet bowl 2 is provided with a rim water outlet 23a (water outlet) and a jet water outlet 23b (water outlet). The rim water outlet 23a is provided in the rim of the toilet bowl 2. Flush water (tap water) is supplied directly to the rim water outlet 23a from a water pipe 31, which is a flush water supply source, by a flush water supply pipe 24 (first supply path) and a rim water supply pipe 24a (first supply path). The rim water outlet 23a spouts the supplied flush water into the bowl 20. In other words, the flush water spouted from the rim water outlet 23a flushes the bowl 20.

[0035] Incidentally, "directly" means that flush water is supplied from water pipe 31 without passing through a water tank. The toilet 2 is a direct pressure type toilet in which flush water is discharged, supplied directly from water pipe 31. Also, in this explanation, the tap water supplied from water pipe 31 will be referred to as flush water.

[0036] The Z outlet 23b is provided below the trap 21. Flush water is directly supplied to the Z outlet 23b from the water pipe 31, which is the flush water supply source, by the flush water supply pipe 24 (first supply path) and the Z supply pipe 24b (first supply path). The Z outlet 23b discharges the supplied flush water into the trap 21. The flush water discharged from the Z outlet 23b causes a siphon effect in the trap 21. This siphon effect generates negative pressure in the drain pipe. As a result, the accumulated water 22 in the bowl 20 is discharged into the drain pipe. This causes the user's waste to be discharged into the drain pipe.

[0037] The flush water supply pipe 24, the rim water supply pipe 24a, and the jet water supply pipe 24b are connected by a three-way valve 25. The three-way valve 25 switches between supplying or stopping (stopping water) flush water to the rim water supply pipe 24a and the jet water supply pipe 24b, respectively.

[0038] When the flush water supply conduit 24 and the rim water supply conduit 24a are placed in communication with each other by the three-way valve 25, flush water is supplied to the rim water supply conduit 24a and flush water is discharged from the rim water outlet 23a. When the flush water supply conduit 24 and the rim water supply conduit 24a are placed in a non-communicating state by the three-way valve 25, flush water is not supplied to the rim water supply conduit 24a and flush water is not discharged from the rim water outlet 23a.

[0039] When the flush water supply pipe 24 and the Z feed pipe 24b are connected by the three-way valve 25, flush water is supplied to the Z feed pipe 24b and flush water is discharged from the Z outlet 23b. When the flush water supply pipe 24 and the Z feed pipe 24b are disconnected by the three-way valve 25, flush water is not supplied to the Z feed pipe 24b and flush water is not discharged from the Z outlet 23b.

[0040] The three-way valve 25 can put the flush water supply line 24 and the rim supply line 24a in a non-communicating state, and can also put the flush water supply line 24 and the jet supply line 24b in a non-communicating state. In this case, flush water is not discharged from the rim spout 23a and the jet spout 23b.

[0041] The three-way valve 25 switches the supply destination of flush water to either the rim water supply line 24a or the jet water supply line 24b, thereby switching between rim spouting and jet water spouting. The three-way valve 25 is controlled by the control device 26 of the toilet 2 (see FIG. 3).

[0042] The flush water supply pipeline 24 is connected to a water pipe 31 via a branch fitting 30. A stop valve 32 is provided on the water pipe 31.

[0043] The vital information measuring device 4 is provided to the side of the toilet 2. The vital information measuring device 4 may also be provided behind the toilet 2. The vital information measuring device 4 comprises a constant flow valve 40, a flowmeter 41 (discharge water volume measuring section), a trap tank 42, a drainage pipe pressure measuring sensor 43, a water level forming pipe 44 (water level fluctuating section), a pressure sensor 45, a plurality of on-off valves 46, 47, 48, and a control device 49 (see FIG. 3).

[0044] Constant flow valve 40 is provided in water replenishment conduit 50 (second supply conduit). Water replenishment conduit 50 is connected to water pipe 31 via branch fitting 30. Flush water for replenishing water to adjust the water level of pooled water 22 in bowl 20 is directly supplied to water replenishment conduit 50 from water pipe 31, which is a flush water supply source. Water replenishment conduit 50 is connected to jet water supply conduit 24b by connecting fitting 51. That is, flush water for replenishing water to adjust the water level of pooled water 22 in bowl 20 is discharged from jet water outlet 23b into trap 21. By providing constant flow valve 40 in water replenishment conduit 50, the flow rate of flush water for replenishing water is stabilized.

[0045] The flow meter 41 is provided in the refill water conduit 50. The flow meter 41 is provided downstream of the constant flow valve 40 in the flow direction of flush water with the branch fitting 30 upstream and the connecting fitting 51 downstream. The flow meter 41 is provided upstream of the attachment position of the connecting fitting 53 that connects the connecting conduit 52 (third supply line) to the refill water conduit 50. In other words, the flow meter 41 is provided upstream of the connection point of the connecting conduit 52. Specifically, the flow meter 41 is provided upstream of the opening / closing valve 46. The connecting conduit 52 is a conduit that connects the refill water conduit 50 and the water level formation pipe 44. The flow meter 41 measures the flow rate of flush water flowing through the refill water conduit 50. Specifically, the flow meter 41 measures the amount of water discharged by refilling.

[0046] The trap tank 42 is a drain tank that stores excess water that overflows from the water level formation pipe 44. The water in the trap tank 42 is discharged to the drain pipe via the drain pipe connecting line 54. The water stored in the trap tank 42 acts as a seal between the drain pipe and the water level formation pipe 44.

[0047] The drain pipe pressure measurement sensor 43 measures the pressure due to the air in the trap tank 42, that is, the pressure due to the air in the drain pipe generated by the air flow through the building's ventilation pipe.

[0048] The water level forming pipe 44 is a standpipe section that extends vertically and has a predetermined height. The water level forming pipe 44 is connected to the trap tank 42 by an overflow pipe 44a. The upper end of the water level forming pipe 44 is open to the atmosphere. The water level of the water level forming pipe 44 fluctuates according to the water level of the stored water 22 in the bowl 20. Specifically, when the water level forming pipe 44 is connected to the bowl 20, the water level of the water level forming pipe 44 fluctuates according to the water level of the stored water 22 in the bowl 20.

[0049] When the on-off valve 47 and the on-off valve 48 are opened, the water level forming pipe 44 communicates with the bowl 20. Specifically, the water level forming pipe 44 communicates with the bowl 20 through a part of the jet water supply pipe 24b, a part of the water replenishment pipe 50, and the connection pipe 52. This forms a U-shaped pipe with both ends open to the atmosphere. Therefore, the water level in the water level forming pipe 44 and the water level of the pooled water 22 in the bowl 20 become the same.

[0050] Pressure sensor 45 is provided in connecting pipe 52. Pressure sensor 45 measures the water pressure (head pressure) in water level formation pipe 44. When on-off valve 47 and on-off valve 48 are open, the water level in water level formation pipe 44 and the water level of pooled water 22 in bowl 20 are the same water level. Therefore, by measuring the water pressure in water level formation pipe 44 with pressure sensor 45, the water level of pooled water 22 in bowl 20 can be measured.

[0051] The on-off valve 46 is provided in the make-up water pipe 50. The on-off valve 46 is provided in the make-up water pipe 50 between the flow meter 41 and the connecting fitting 53.

[0052] The on-off valve 47 is provided in the water replenishment pipeline 50. The on-off valve 47 is provided in the water replenishment pipeline 50 between the connecting fitting 51 and the connecting fitting 53. Specifically, the on-off valve 47 is provided in the water replenishment pipeline 50 between the connecting fitting 53 and a ball valve 55. The ball valve 55 is a valve that can release the connection between the toilet 2 and the vital information measuring device 4. The connection between the toilet 2 and the vital information measuring device 4 is released by closing the ball valve 55. The ball valve 55 is normally open.

[0053] The on-off valve 48 is provided in the connecting pipe 52. The on-off valve 48 is provided in the connecting pipe 52 between the pressure sensor 45 and the connecting fitting 53.

[0054] Next, the control device 49 will be described with reference to Fig. 3. Fig. 3 is a block diagram illustrating the control device 49 of the vital information measuring device 4.

[0055] The control device 49 is a computer, and includes a storage unit 60 and a control unit 61. The control device 49 is provided so as to be able to communicate with the operation unit 10. The control device 49 is also provided so as to be able to communicate with the control device 26 of the toilet 2.

[0056] The memory unit 60 stores programs that control various processes executed in the vital information measuring device 4. The memory unit 60 is realized by a storage device such as a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory. The memory unit 60 stores a relational expression between the water level and the water volume of the stored water 22 in the bowl 20. The memory unit 60 stores the output value of the pressure sensor 45 when the water level forming pipe 44 is in a substantially full water level state. The relational expression between the water level and the water volume of the stored water 22 in the bowl 20 and the output value of the pressure sensor 45 when the water level forming pipe 44 is in a substantially full water level state are obtained and stored in advance.

[0057] For example, the relational equation between the water level and water volume of stored water 22 in bowl 20 is calculated by an installer when toilet unit 1 is installed in a toilet room, and stored in memory unit 60. A method for storing the relational equation between the water level and water volume of stored water 22 in bowl 20 will be described with reference to FIG.

[0058] Specifically, first, the installer opens ball valve 55, on-off valve 47, and on-off valve 48. Next, the installer starts water discharge from rim water outlet 23a and jet water outlet 23b, and sets the water level in bowl 20 to overflow water level H. Overflow water level H is the limit water level at which the water in trap 21 overflows from weir portion 21a.

[0059] Next, the installer drains the water 22 in the bowl 20, for example, by 230 milliliters (mL) at a time. That is, the water 22 in the bowl 20 is removed, for example, by 230 mL at a time. Therefore, the water level of the water 22 in the bowl 20 decreases. Then, the installer measures the water pressure in the water level forming pipe 44 by the pressure sensor 45 every time the water 22 in the bowl 20 is drained. Here, the example in which the water is reduced has been described above, but the calibration relationship between the water level and the amount of water can also be obtained by adding a predetermined amount of water from a predetermined water level. Note that since the on-off valve 47 and the on-off valve 48 are open, the water level in the water level forming pipe 44 becomes the same as the water level in the bowl 20.

[0060] In this way, the installer removes a fixed amount of water from bowl 20, and measures the reduced water level at that time with pressure sensor 45. Alternatively, the installer measures the predetermined water level set in the installation and setting work, that is, the water level resulting from adding a fixed amount of water from the measurement start water level, with pressure sensor 45. This allows the installer to calculate the relationship between the output value of pressure sensor 45 and the amount of stored water 22 in bowl 20 of the toilet 2, that is, the relationship between the water level and amount of stored water 22 in bowl 20. The installer stores the calculated relationship in memory unit 60.

[0061] The relation between the water level and the amount of water in the pooled water 22 in the bowl 20 may be calculated by adding a fixed amount of the pooled water 22 from the seal-breaking water level L.

[0062] Returning to Fig. 3, the control unit 61 includes, for example, a computer having a CPU (Central Processing Unit), ROM (Read Only Memory), RAM, a hard disk drive, input / output ports, and various other circuits. At least a part of the control unit 61 can be configured with hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 61 includes an acquisition unit 63, a measurement unit 64 (excretion information measurement unit), and an adjustment unit 65 (water level adjustment unit). The acquisition unit 63, the measurement unit 64, and the adjustment unit 65 may be integrated or further divided into a plurality of units.

[0063] The acquisition unit 63 acquires information relating to the water pressure in the water level formation pipe 44 from the pressure sensor 45. That is, the acquisition unit 63 acquires information relating to the water level of the stored water 22 in the bowl 20. The acquisition unit 63 acquires information relating to the amount of water discharged due to water replenishment from the flow meter 41. The acquisition unit 63 acquires information relating to the pressure due to the air in the trap tank 42 from the drainage piping pressure measurement sensor 43.

[0064] The acquisition unit 63 acquires an operation signal in the operation unit 10. Specifically, the acquisition unit 63 acquires an operation signal of the remote control of the biological information measuring device 4 from the remote control of the biological information measuring device 4.

[0065] The acquisition unit 63 acquires signals related to toilet flushing in the toilet 2 from the control device 26 of the toilet 2. Specifically, the acquisition unit 63 acquires an operation signal from the remote control for the toilet 2, and a signal related to the operating state of the three-way valve 25.

[0066] The measuring unit 64 measures the amount of urine excreted by the user and the urinary flow rate, which is the instantaneous urine volume, based on information related to the water pressure inside the water level forming tube 44. In other words, the measuring unit 64 measures the amount of urine excreted by the user by measuring the water level of the pooled water 22 in the bowl 20.

[0067] Here, the operation of measuring the amount of urine excreted by the user will be described with reference to FIG.

[0068] In this example, the water level of the accumulated water 22 in the bowl 20 during the measurement standby period is set to a predetermined water level Y (hereinafter, sometimes referred to as the measurement start water level Y). The measurement start water level Y is a water level that is a predetermined amount higher than the seal-breaking water level L. The measurement start water level Y is, for example, a water level that is 50 to 55 millimeters (mm) higher than the seal-breaking water level L. Also, the measurement start water level Y is, for example, a water level that is 20 to 30 mm lower than the overflow water level H. Note that the measurement start water level Y is preferably 50 to 100 millimeters (mm) in accordance with the Building Standards Act, with the aim of maintaining a hygienic environment in the drainage pipe and the toilet room.

[0069] As will be described later, the water level when measurement actually starts may differ from the predetermined water level Y (measurement start water level Y).

[0070] During standby for measurement to measure the amount of excreted urine, the water level forming tube 44 is kept almost full, specifically, filled with water up to the upper limit where water does not drain from the overflow tube 44a into the trap tank 42. This is because the patient who is the user may have a disease that makes it difficult to hold in urination. Since the water level forming tube 44 is almost full during standby, it is possible to eliminate the time required to fill the water level forming tube 44 with water in preparation for measurement, and measurement operation can be performed immediately.

[0071] When performing measurement, the measurement unit 64 measures the head pressure of the water level forming pipe 44 in a nearly full water state using the pressure sensor 45 in accordance with the user's operation to start measurement. The measurement unit 64 compares the output value of this pressure sensor 45 with the output value in a nearly full water state that is pre-stored in the memory unit 60. This allows the measurement unit 64 to calibrate the relationship between the water level and the water volume that is stored in the memory unit 60, taking into account environmental variables such as atmospheric pressure and temperature.

[0072] When the user enters the toilet room during measurement standby, the measurement is started by operating a measurement start switch on a remote control for measuring biological information. Note that the measurement may also be started by a personal authentication operation using an ID card, a tag, or the like.

[0073] When the measurement start switch is operated, the measurement unit 64 opens the on-off valve 47 and the on-off valve 48. That is, the measurement unit 64 determines whether or not the measurement start switch is operated, and when the measurement start switch is operated, opens the on-off valve 47 and the on-off valve 48.

[0074] During standby for measurement, on-off valve 47 and on-off valve 48 are closed. By opening on-off valve 47 and on-off valve 48, the water level in water level formation pipe 44 becomes the same as the water level of pooled water 22 in bowl 20. At this time, the water level of pooled water 22 in bowl 20 rises slightly from measurement start water level Y. However, the amount of pooled water 22 is sufficiently large compared to the amount of water fluctuating in water level formation pipe 44. Therefore, the amount of rise is slight, and the water level of pooled water 22 in bowl 20 does not substantially change from measurement start water level Y.

[0075] When the biological information measuring device 4 is in a state where urination information can be measured, for example, a message "Please urinate" is displayed on a monitor provided on a remote control for measuring biological information. For example, when the on-off valve 47 and the on-off valve 48 are in an open state, it is determined that the urination information can be measured. Thereafter, the user urinates into the bowl 20. When the user finishes urination, the water level of the pooled water 22 in the bowl 20 rises from the measurement start water level Y to the post-urination water level C. At the same time, the water level in the water level forming tube 44 becomes the post-urination water level C.

[0076] Thereafter, when the user operates the urination end switch on the remote control for measuring biological information, the measurement unit 64 calculates the amount of urine excreted by the user and measures the amount of urine excreted by the user. That is, the measurement unit 64 determines whether or not the urination end switch has been operated, and measures the amount of urine excreted by the user when the urination end switch has been operated.

[0077] Measurement unit 64 calculates the water level of water level forming tube 44, i.e., the water level of pooled water 22 in bowl 20 (post-urination water level C) based on information on the water pressure in water level forming tube 44 acquired from pressure sensor 45. Measurement unit 64 calculates the rising water volume in bowl 20, i.e., the amount of urine excreted by the user, from the relational equation between the water level and water volume of pooled water 22 in bowl 20 and the measured water level of pooled water 22 in bowl 20.

[0078] When the measurement of the amount of urine excreted by the user is completed, the measurement unit 64 transmits the measurement result to, for example, a printer. As a result, the measurement result of the amount of urine excreted by the user is printed out from the printer. The measurement unit 64 may transmit the measurement result to a terminal device such as a smartphone or a clinical electronic medical record system.

[0079] Furthermore, the measuring unit 64 may calculate not only the amount of urine excreted by the user, but also other urination information such as urination time (seconds), maximum urinary flow rate (mL / second), average urinary flow rate (mL / second), time to reach maximum urinary flow rate (seconds), and hesitation time (seconds). The urination time is the time from when urine starts to be discharged into the bowl 20 until when urine stops being discharged into the bowl 20. The urinary flow rate is the amount of urine per unit time, that is, the urination speed. The maximum urinary flow rate is the maximum value of the urinary flow rate. The average urinary flow rate is the average value of the urinary flow rate. The time to reach maximum urinary flow rate is the time from when urination starts until when the urinary flow rate reaches its maximum value. The hesitation time is the time from when the message "Please urinate" is displayed on the monitor until urination starts.

[0080] In addition, when pre-use water spraying (pre-misting) is performed by the sanitary washing device 3 before the user urinates, the measurement unit 64 measures the amount of urine excreted by the user taking into account the amount of cleaning water sprayed by the pre-use water spraying.

[0081] Note that measurement unit 64 may calibrate the pre-stored relational equation between the water level and the water volume of stored water 22 in bowl 20 based on the measurement results of drain pipe pressure measurement sensor 43. As a result, even if positive or negative pressure occurs in the drain pipe and causes fluctuations in the water level of stored water 22 in bowl 20, measurement unit 64 can measure the amount of urine excreted by the user while correcting the effects of these fluctuations.

[0082] The adjustment unit 65 replenishes water after the bowl 20 has been washed with wash water, and adjusts the water level of the accumulated water 22 in the bowl 20.

[0083] The flushing of bowl 20 is performed when the user operates the flush switch on the toilet remote control. Specifically, first, bowl 20 is flushed by spouting water from rim spout 23a. Then, water is spouted from jet spout 23b to drain substantially all of stored water 22 into the drain pipe. After that, water is spouted from rim spout 23a to supply stored water 22 to bowl 20 until it exceeds seal-breaking water level L. Water is spouted from rim spout 23a so that the level of stored water 22 in bowl 20 is lower than measurement start water level Y.

[0084] The adjustment unit 65 performs water replenishment when the water level of the water 22 in the bowl 20 is lower than the measurement start water level Y, and adjusts the water level of the water 22 in the bowl 20 to the measurement start water level Y.

[0085] Here, the adjustment of the water level of the water 22 in the bowl 20 by the adjustment unit 65 will be described.

[0086] After cleaning the bowl 20 with cleaning water, the adjustment unit 65 measures the water level of the water level forming pipe 44, i.e., the water level of the accumulated water 22 in the bowl 20, based on information on the water pressure in the water level forming pipe 44 obtained from the pressure sensor 45.

[0087] Specifically, adjustment unit 65 determines whether or not flushing of bowl 20 with flush water has finished. Adjustment unit 65 determines that flushing of bowl 20 with flush water has finished when the flush switch on the toilet remote control is operated and the second discharge of water from rim spout 23a has finished.

[0088] Then, when cleaning of the bowl 20 with cleaning water is completed, the adjustment unit 65 measures the water level of the water level forming pipe 44, i.e., the water level of the stored water 22 in the bowl 20, based on information on the water pressure in the water level forming pipe 44 obtained from the pressure sensor 45.

[0089] Adjustment unit 65 may measure the water level of stored water 22 in bowl 20 a predetermined time after cleaning of bowl 20 with cleaning water is completed. The predetermined time is a time that is set in advance, and is the time it takes for the water level of stored water 22 in bowl 20 to stabilize. Furthermore, when nozzle cleaning or post-use watering (after-misting) is performed by sanitary cleaning device 3, adjustment unit 65 may measure the water level of stored water 22 in bowl 20 a predetermined time after the nozzle cleaning or post-use watering is performed.

[0090] Adjustment unit 65 calculates the amount of water to be replenished based on the measured water level of stored water 22 in bowl 20. Adjustment unit 65 calculates the amount of water to be replenished necessary to bring the measured water level of stored water 22 in bowl 20 to measurement start water level Y. Adjustment unit 65 calculates the amount of water to be replenished necessary to bring the measured water level of stored water 22 in bowl 20 to measurement start water level Y, based on the relational equation between the water level and water volume of stored water 22 in bowl 20 and the measured water level of stored water 22 in bowl 20.

[0091] Next, the adjustment unit 65 closes the on-off valve 48 and opens the on-off valve 46. This causes flush water to flow from the water pipe 31 to the water replenishment pipe 50, and flush water is supplied from the jet water outlet 23b into the trap 21, thereby performing water replenishment.

[0092] Adjustment unit 65 adjusts the water level of stored water 22 in bowl 20 based on the amount of water discharged due to water replenishment measured by flowmeter 41. Specifically, adjustment unit 65 determines whether the amount of water discharged due to water replenishment has reached the calculated amount of water replenishment. When the amount of water discharged measured by flowmeter 41 reaches the calculated amount of water replenishment, adjustment unit 65 closes on-off valve 47. This stops the supply of flush water from jet water outlet 23b into trap 21, and water replenishment ends. As a result of water replenishment, the water level of stored water 22 in bowl 20 reaches measurement start water level Y.

[0093] The adjustment unit 65 opens the on-off valve 48 after setting the water level of the water 22 in the bowl 20 to the measurement start water level Y. This causes flushing water to flow into the water level formation pipe 44, which becomes substantially full. After opening the on-off valve 48, the adjustment unit 65 determines whether the flow rate measured by the flowmeter 41 has reached a predetermined flow rate. The predetermined flow rate is a flow rate that has been set in advance.

[0094] The predetermined flow rate is a flow rate that fills the water level forming pipe 44 with water. The predetermined flow rate may be a flow rate that fills the water level forming pipe 44 with water and allows flushing water to flow into the trap tank 42 through the overflow pipe 44a. For example, the predetermined flow rate may be a flow rate that does not cause the water level in the trap tank 42 to drop below the tip of the overflow pipe 44a. The predetermined flow rate may be a flow rate that fills the water level forming pipe 44 with water and allows water to start draining from the trap tank 42 through the drain pipe connecting pipe 54. The adjustment unit 65 may periodically increase the predetermined flow rate so that the trap tank 42 does not lose its water seal.

[0095] When the flow rate measured by the flowmeter 41 reaches a predetermined flow rate after opening the on-off valve 48, the adjustment unit 65 closes the on-off valve 46 and the on-off valve 48. Since the predetermined flow rate of water flows into the water level formation pipe 44, the water level formation pipe 44 becomes almost full.

[0096] Next, the urinary excretion amount measurement process according to the embodiment will be described with reference to Fig. 4. Fig. 4 is a flow chart for explaining the urinary excretion amount measurement process according to the embodiment. Note that before the urinary excretion amount measurement process is started, specifically, before the measurement start switch of the remote control for measuring biological information is operated, the on-off valve 46, the on-off valve 47, and the on-off valve 48 are in a closed state.

[0097] The control unit 61 determines whether or not a measurement start switch of a remote control for measuring biological information has been operated (S100). If the measurement start switch has not been operated (S100: No), the control unit 61 ends this processing.

[0098] When the measurement start switch is operated (S100: Yes), the control unit 61 opens the on-off valve 47 and the on-off valve 48 (S101).

[0099] The control unit 61 determines whether or not the urination end switch of the biological information measurement remote control has been operated (S102). If the urination end switch has not been operated (S102: No), the control unit 61 repeats the process until the urination end switch is operated (S102).

[0100] When the urination end switch is operated (S102: Yes), the control unit 61 measures the amount of urine excreted by the user (S103). The control unit 61 measures the water level of the stored water 22 in the bowl 20 based on information on the water pressure in the water level forming tube 44 obtained from the pressure sensor 45. The control unit 61 then calculates the rising water volume in the bowl 20, i.e., the amount of urine excreted by the user, from the relational equation between the water level and the water volume of the stored water 22 in the bowl 20 and the measured water level of the stored water 22 in the bowl 20.

[0101] Next, the control unit 61 transmits the measurement result of the amount of urine excreted by the user (S104). As a result, for example, the measurement result is output from a printer.

[0102] Next, the water refilling process according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a flow chart explaining the water refilling process according to the embodiment. When the flush switch on the toilet remote control is operated, the control unit 61 starts the water refilling process described below.

[0103] The control unit 61 determines whether or not cleaning of the bowl 20 is completed (S200). If cleaning of the bowl 20 is not completed (S200: No), the control unit 61 repeats the process (S200) until cleaning of the bowl 20 is completed.

[0104] When cleaning of bowl 20 is completed (S200: Yes), control unit 61 measures the water level of pooled water 22 in bowl 20 (S201). Control unit 61 measures the water level of pooled water 22 in bowl 20 by measuring the water level of water level formation pipe 44 based on information on the water pressure in water level formation pipe 44 acquired from pressure sensor 45.

[0105] The control unit 61 calculates the amount of water to be replenished (S202). The control unit 61 calculates the amount of water to be replenished in order to bring the measured water level of the stored water 22 in the bowl 20 to the measurement start water level Y.

[0106] Next, the control unit 61 starts water replenishment (S203). Specifically, the control unit 61 closes the on-off valve 48 and opens the on-off valve 46. This causes flush water to flow from the water pipe 31 to the water replenishment pipe 50, and flush water is supplied from the jet water outlet 23b into the trap 21, thereby performing water replenishment.

[0107] Next, the control unit 61 determines whether the amount of water discharged due to water replenishment has reached the water replenishment amount (S204). When the flow rate of flush water measured by the flow meter 41 has reached the water replenishment amount, the control unit 61 determines that the amount of water discharged due to water replenishment has reached the water replenishment amount.

[0108] If the amount of water discharged due to water replenishment has not reached the water replenishment amount (S204: No), the control unit 61 repeats the process until the amount of water discharged due to water replenishment reaches the water replenishment amount (S204).

[0109] When the amount of water discharged by the water replenishment reaches the water replenishment amount (S204: Yes), the control unit 61 ends the water replenishment (S205). Specifically, the control unit 61 closes the on-off valve 47. By performing the water replenishment, the water level of the pooled water 22 in the bowl 20 becomes the measurement start water level Y.

[0110] Next, the control unit 61 opens the on-off valve 48 (S206). This causes water to flow into the water level formation pipe 44, and the water level formation pipe 44 becomes substantially full.

[0111] The control unit 61 determines whether the flow rate measured by the flowmeter 41 has reached the predetermined flow rate after opening the on-off valve 48 (S207). If the flow rate has not reached the predetermined flow rate (S207: No), the control unit 61 repeats the process until the flow rate reaches the predetermined flow rate (S207).

[0112] When the flow rate reaches the predetermined flow rate (S207: Yes), the control unit 61 closes the on-off valve 46 and the on-off valve 48 (S208).

[0113] Here, a toilet unit 100 according to a comparative example will be described with reference to Fig. 6. Fig. 6 is a system configuration diagram illustrating the toilet unit 100 according to the comparative example.

[0114] A vital information measuring device 101 of a toilet unit 100 according to a comparative example is equipped with a water replenishment tank device 102. The water replenishment tank device 102 is equipped with a water replenishment tank 103 and a water replenishment pump 104. The vital information measuring device 101 stores flush water for replenishment in the water replenishment tank 103 from the water pipe 31. When performing water replenishment, the vital information measuring device 101 performs water replenishment by causing the flush water stored in the water replenishment tank 103 to flow into a water replenishment pipe 105 by the water replenishment pump 104. The toilet unit 100 performs water replenishment from the water replenishment tank 103 via the water replenishment pipe 105.

[0115] For example, the toilet unit 100 according to the comparative example has a vital information measuring device 101 with a water replenishment tank device 102 provided behind the toilet 2. As a result, the toilet unit 100 according to the comparative example is large. Also, because the toilet unit 100 according to the comparative example has the water replenishment tank device 102, it is necessary to remove the water replenishment tank device 102 when removing the toilet 2. In a toilet unit 100 provided in a toilet room of a medical institution, it is unavoidable for foreign objects such as incontinence pads or pessaries attached inside the vagina to fall, which may increase the maintenance burden when removing the foreign objects.

[0116] As another comparative example, it is also possible to add water in accordance with the water level of stored water 22 in bowl 20 measured by pressure sensor 45. However, the response of the change in the water level of stored water 22 in bowl 20 measured by pressure sensor 45 to the actual change in the water level of stored water 22 in bowl 20 may be slow, making it difficult to fine-tune the water level in bowl 20.

[0117] The toilet unit 1 comprises a toilet 2 and a vital information measuring device 4. The toilet 2 has a bowl 20 that receives the user's waste. The vital information measuring device 4 measures the amount of urine excreted by the user. The vital information measuring device 4 comprises a measurement unit 64, an adjustment unit 65, and a flowmeter 41. The measurement unit 64 measures the amount of urine excreted by the user by measuring the water level of the stored water 22 in the bowl 20. The adjustment unit 65 refills water after the bowl 20 has been flushed with flushing water, and adjusts the water level of the stored water 22 in the bowl 20. The flowmeter 41 measures the amount of water discharged by the refill. The adjustment unit 65 adjusts the water level of the stored water 22 in the bowl 20 based on the amount of water discharged by the refill measured by the flowmeter 41.

[0118] As a result, the toilet unit 1 can accurately measure the amount of water discharged by refilling, for example, without providing a refilling water tank 103 that stores flush water for refilling. As a result, the toilet unit 1 can be made smaller. Specifically, the toilet unit 1 can reduce the height of the toilet unit 1. The toilet unit 1 can also increase the degree of freedom in installing the vital information measuring device 4 that does not have a refilling water tank 103, and for example, the vital information measuring device 4 can be installed in a location where maintenance is easy. The toilet unit 1 can improve the maintainability of the vital information measuring device 4. In addition, when removing a foreign object that has fallen, for example, since there is no refilling water tank device, a worker can easily remove the foreign object. In other words, the toilet unit 1 can improve the maintainability of the toilet unit 1 by making it easy to remove a foreign object that has been dropped. Furthermore, toilet unit 1 can fine-tune the water level in bowl 20 by adjusting the water level of stored water 22 in bowl 20 based on the amount of water discharged due to water replenishment measured by flowmeter 41, making it possible to accurately adjust the water level of stored water 22 in bowl 20. Furthermore, by using flowmeter 41 to adjust the amount of water discharged due to water replenishment, toilet unit 1 can accurately adjust the water level in bowl 20 with a simple configuration.

[0119] Water is replenished by flushing water supplied directly from the water pipe 31.

[0120] As a result, the toilet unit 1 can accurately measure the amount of water discharged due to water replenishment, for example, without providing a water replenishment tank 103 that stores flush water for refilling the water. This allows the toilet unit 1 to be made smaller. The toilet unit 1 also allows for greater freedom in the installation of the vital information measuring device 4, which does not have a water replenishment tank 103, and, for example, the vital information measuring device 4 can be installed in a location where maintenance is easy. In other words, the toilet unit 1 can improve the maintainability of the vital information measuring device 4.

[0121] The toilet unit 1 comprises a flush water supply pipe 24 through which flush water to be discharged into the bowl 20 flows, and a water replenishment pipe 50 through which flush water to be replenished flows. A flow meter 41 is provided in the water replenishment pipe 50.

[0122] As a result, when performing maintenance on the flowmeter 41, the toilet unit 1 can prevent the flush water supply pipe 24 from interfering with the maintenance of the flowmeter 41. Therefore, the toilet unit 1 can improve the ease of maintenance of the flowmeter 41.

[0123] The toilet unit 1 is equipped with a water level forming pipe 44. The water level of the water level forming pipe 44 fluctuates according to the water level of the stored water 22 in the bowl 20. A connecting pipe 52 is connected to the water make-up pipe 50. The flow meter 41 is provided upstream of the point where the connecting pipe 52 is connected.

[0124] This allows the toilet unit 1 to measure the amount of water discharged by refilling water, based on the flow rate measured by flowmeter 41, which is provided upstream of connecting pipe 52 branching off from refilling water pipe 50. Therefore, the toilet unit 1 can accurately adjust the water level in bowl 20 by refilling water.

[0125] The adjustment unit 65 calculates the amount of water to be replenished based on the level of the water 22 in the bowl 20 after washing, and replenishes water so that the amount of water discharged by the replenishment measured by the flowmeter 41 becomes the amount of water to be replenished.

[0126] This allows the toilet unit 1 to accurately adjust the water level in the bowl 20 after water is refilled.

[0127] The flow meter 41 may be detachable. This allows the toilet unit 1 to improve ease of maintenance of the vital information measuring device 4.

[0128] In the toilet unit 1, for example, the vital information measuring device 4 is provided to the side of the toilet 2. This allows workers to access the vital information measuring device 4 from the side of the toilet 2, facilitating maintenance of and updating of the vital information measuring device 4. Also, for example, because the vital information measuring device 4 is provided to the side of the toilet 2, when removing the toilet 2 to perform maintenance on the drain socket 28, the worker can easily access the drain socket 28, improving the maintainability of the drain socket 28.

[0129] The toilet unit 1 may be configured such that the toilet 2 is provided in a toilet room, and the vital information measuring device 4 is added later. In other words, the vital information measuring device 4 may be attached later.

[0130] The toilet unit 1 differs from the toilet unit 100 according to the comparative example in that it is not provided with a refill water tank 103, and by refilling water, it is possible to prevent flush water in the refill water tank 103 from freezing.

[0131] The toilet unit 1 may periodically control the on-off valves 46, 48 so that flush water flows from the water level formation pipe 44 to the trap tank 42. This allows the toilet unit 1 to discharge air bubbles generated in the water replenishment pipe 50, the connecting pipe 52, the water level formation pipe 44, etc., to the trap tank 42, and remove air bubbles generated in the water replenishment pipe 50, etc. The toilet unit 1 can also prevent flush water from freezing in the water replenishment pipe 50, etc.

[0132] The toilet unit 1 may replenish water from the rim water spout 23a. For example, the water replenishment pipe 50 may be connected to the rim water supply pipe 24a. The toilet unit 1 may also replenish water from the sanitary flushing device 3.

[0133] The toilet unit 1 according to the modified example predicts the water level after flushing in the bowl 20 based on the amount of water discharged due to make-up water measured by the flowmeter 41. For example, the control unit 61 calculates the water pressure of the flush water from the water pipe 31 based on the amount of water discharged due to make-up water measured by the flowmeter 41. The control unit 61 predicts the water level after flushing in the bowl 20 based on the calculated water pressure and design information such as the flush water supply pipe 24. Design information such as the flush water supply pipe 24 includes information such as the length from the branch fitting 30 to the rim outlet 23a and the Z outlet 23b, the diameter of the pipes, and pressure loss.

[0134] As a result, the toilet unit 1 can adjust the water level of the pooled water 22 with high precision, without using the pressure sensor 45 to measure the water level of the pooled water 22, even if the flush water volume setting is changed, for example.

[0135] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
