Description

  The present invention relates to a urine volume measuring toilet apparatus having a flush toilet and a cabinet for storing a water level measuring means and a urine volume information calculating means.

  The urine volume measuring toilet device is mainly used in a hospital or the like to grasp the health condition of a patient. For this reason, the urine lid is generally not attached to the urine volume measuring toilet device for the purpose of reducing the burden caused by the operation of opening the stool lid or preventing the patient from falling. (For example, Patent Document 1)

JP 2008-248556 A

However, recently, a toilet lid may be required even in a urine volume measuring toilet device in order to prevent scattering of filth during washing. When a urine volume measuring toilet device is provided with a stool lid, the stool lid can be opened only upright or forward tilted by a cabinet containing urine volume information calculation means installed behind the toilet bowl. Since the lid cannot be made stable and independent, the stool lid may fall during use.
In order to prevent the toilet lid from falling down, it is conceivable that the toilet lid is tilted backward when the toilet lid is opened by setting the pivot point of the toilet lid to the front (position away from the cabinet). . However, for that purpose, it is necessary to install the toilet that supports the toilet lid with respect to the cabinet to the front, and the length of the urine volume measuring toilet device in the front-rear direction becomes long. Then, the front space of the urine volume measurement toilet device in the toilet room is compressed, which may hinder a user using a wheelchair or the like from using the urine volume measurement toilet device.

  Therefore, the present invention has been made to solve the above-described problem, and the urine volume measuring toilet device is opened when the toilet lid is opened without changing the length of the urine volume measuring toilet device in the front-rear direction. The purpose is to prevent the lid from falling down.

  In this urine volume measurement toilet device, the toilet lid can be tilted backward because the front side of the cabinet is positioned rearward of the lower side, so that the pivot axis support point of the toilet lid with respect to the cabinet is not pulled forward Even the stool lid can be made independent. Therefore, a self-supporting state can be maintained when the toilet lid is opened without changing the length of the urine volume measuring toilet device in the front-rear direction.

In the urine volume measuring toilet apparatus according to the present invention, preferably, the front surface of the cabinet is inclined upward from below so as to come into contact with the toilet lid when the toilet lid is opened.
Accordingly, when the user leans over the toilet lid while facing up, the toilet lid and the front of the cabinet come into wide contact with each other along the inclination, so that the force acting on the pivot point of the toilet lid can be reduced. It is possible to prevent the stool lid from being damaged or detached.

In the urine volume measuring toilet apparatus according to the present invention, preferably, the toilet seat box has a built-in drive motor that opens and closes the toilet lid as a functional unit, and the drive motor is operated when the flush toilet is washed with water. Operate and rotate so that the stool lid is closed.
Therefore, when the flush toilet is washed with water, the toilet lid is automatically closed, and it is possible to prevent scattering of filth during washing due to forgetting to close the toilet lid.

  According to the present invention, it is possible to maintain a self-supporting state when the toilet lid is opened without changing the length of the urine volume measuring toilet device in the front-rear direction.

It is a side view which shows the whole urine volume measuring toilet apparatus in embodiment of this invention. It is a side view which shows the whole urine volume measurement toilet apparatus in the modification of embodiment of this invention.

  The urine volume measuring toilet apparatus according to the embodiment of the present invention will be described below. FIG. 1 is a perspective view showing the entire urine volume measuring toilet apparatus according to an embodiment of the present invention. First, the overall configuration of the urine volume measuring toilet apparatus 1 will be described with reference to FIG.

  As shown in FIG. 1, a urine volume measuring toilet device 1 according to this embodiment includes a flush toilet 2 capable of washing excrement and the like with wash water supplied from the outside, and a rear upper surface (bowl portion) of the flush toilet 2. The toilet seat box 3 placed and fixed on the rear upper surface of 21 and the flush toilet 2 are installed so as to cover the rear of the flush toilet 2 and the rear of the toilet seat box 3. It consists of a cabinet 4.

  The flush toilet 2 is made of earthenware or resin, and has a bowl portion 21 that receives the excrement of the user in a state in which accumulated water is formed. The toilet seat box 3 has a resin-made casing in which a later-described functional part is incorporated, and is fixed to the upper surface of the rear part of the bowl part 21. A toilet seat 30 and a toilet lid 31 made of resin are rotatably attached to the toilet seat box 3. In the present embodiment, the toilet lid 31 includes a toilet lid main body 311 and an outer peripheral wall 312 that protrudes downward from the outer edge of the toilet lid main body 311.

By providing the toilet lid 31 in the toilet seat box 3 and moving the toilet lid 31 to the closed state at the time of washing, the toilet lid 31 serves as a cover for covering the bowl portion 21 and can prevent scattering of filth. .
In the present specification, the forward direction as viewed from the user sitting on the toilet seat 30 is "front",
The rear side viewed from the user sitting on the toilet seat 30 is referred to as “rear”. Further, the right side as viewed from the user standing in front of the flush toilet 2 facing the rear side is referred to as “right side”, and the left side is referred to as “left side”.

  Next, the internal configuration of the urine volume measuring toilet apparatus 1 according to the embodiment of the present invention will be described. FIG. 2 is a functional block diagram in the embodiment of the present invention. As shown in FIG. 2, the urine volume measuring toilet device 1 functionally includes a toilet unit 20 composed of a flush toilet 2 and a functional part built in the toilet seat box 3, and a flush in the toilet unit 20. The storage unit 23 is formed in the bowl portion 21 of the toilet 2 and is connected to the measurement unit 40 stored in the cabinet 4 through a water conduit 26.

The toilet seat box 3 is provided with a local cleaning device 321 for adding cleaning water to a human body part from a nozzle (not shown) after being added as a predetermined function part. Further, a drive motor 322 for opening and closing the toilet lid 31 and a water supply means 323 for supplying cleaning water to the flush toilet 2 are incorporated. The operations of the local cleaning device 321, the drive motor 322, and the water supply means 323 are controlled by a toilet control unit 32 configured by a microcomputer.

  The toilet-side control unit 32 can receive an operation signal from a remote controller (not shown), and when the user instructs toilet flushing with the remote controller after stool, the water supply means 323 is controlled to wash the flush toilet 2 Water is supplied and the flush toilet 2 is washed. It should be noted that when the flush toilet 2 is washed, the drive motor 322 is actuated prior to the operation of the water supply means 323 so that the toilet lid 31 is closed. In this way, the toilet-side control unit 32 controls the toilet lid 31 to be closed when the water supply means 323 is driven, so that cleaning water mixed with filth is scattered from the bowl portion 21 when the flush toilet 2 is washed. It becomes possible to suppress that.

Next, the structure of the flow path through which water flows as a function of the flush toilet 2 will be described. The flush toilet 2 includes a bowl portion 21 and a trap pipe 22 that communicates with the bottom portion of the bowl portion 21 and forms the accumulated water 23 at the lower portion of the bowl portion 21. The trap pipe 22 is formed of a rising pipe (not shown) that extends obliquely upward from the bottom of the bowl part 21 and a down pipe (not shown) that extends vertically downward from the rising pipe. In the lower part of 21, the accumulated water 23 is formed with the upper limit of the height position (hereinafter referred to as the overflow position) of the weir part that becomes the bottom of the bending point of the ascending pipeline and the descending pipeline. The stored water 23 formed in this way prevents the bad odors and sanitary insects generated inside the drain pipe 11 from entering the bowl portion 21.
In addition, a resin drain socket 10 is attached to the lower end of the descending pipeline, which is the downstream end of the trap pipeline 22, and communicates with the building drain pipe 11 via the drain socket 10.

Next, the flow of water during washing of the flush toilet 2 will be described. When the flush toilet 2 is washed, water supplied from a water supply source (not shown) is supplied to the rim water discharge nozzle 24 and the jet water discharge nozzle 25 that are fixed to the bowl portion 21 via the water supply means 323. . Here, water discharged from the rim water discharge nozzle 24 forms a swirl flow in a substantially horizontal state around the upper edge of the bowl portion 21, and water discharged from the jet water discharge nozzle 25 is stored water formed at the bottom of the bowl portion 21. The water 23 is discharged, and the accumulated water 23 is discharged in a direction toward the ascending pipeline of the trap pipeline 22.
The water supplied from the water supply source is supplied to the bowl portion 21 of the flush toilet 2 via the rim water discharge nozzle 24 or the jet water discharge nozzle 25.
Specifically, the water supply means 323 can independently control the cleaning water directed to the rim water discharge nozzle 24 and the jet water discharge nozzle 25, and discharge water from the rim water discharge nozzle 24 at the initial stage of the cleaning so that the bowl portion 21 The internal waste is dropped into the water storage 23, and then discharged from the jet water discharge nozzle 25 to discharge the waste water 23 mixed with the waste to the drainage pipe 11, and finally water is discharged from the rim water discharge nozzle 24 again (hereinafter referred to as water discharge). This is referred to as “rear rim water discharge”), and the accumulated water is formed in the lower portion of the bowl portion 21. In the flush toilet 2 according to the present embodiment, in order to measure the urine amount of the urine excreted in the bowl portion 21 by the measurement unit 40, the height position of the stored water 23 formed in the bowl portion 21 is used. The amount of cleaning water supplied from the rim water spouting nozzle 24 in the rear rim water spouting is controlled so as to be a measurement starting water level that is lower than the overflow position and the upstream end of the trap pipe 22 is not exposed. The measurement water level is controlled to a position that does not exceed the overflow position even if a general adult excretes urine.

  Next, the measurement unit 40 housed in the cabinet 4 will be described. The measurement unit 40 is connected to the stored water 23 by the water conduit 26, and processes the water level measuring means 41 for measuring the water level change of the stored water 23, the operation control of the water level measuring means 41 and the measurement result. And urine volume information calculating means 42 for calculating measurement information such as urine volume.

The water level measuring means 41 is configured using, for example, a pressure sensor provided in the water conduit 26 that rises vertically inside the cabinet 4. The pressure sensor can measure the pressure (water head pressure) generated by the water level of the stored water 23 as the stored water pressure.
On the other hand, the urine volume information calculation means 42 is configured by a urine volume measurement control unit 43 configured by a microcomputer and a nonvolatile memory (EEPROM), and shows the relationship between the stored water pressure and the stored water volume depending on the shape of the bowl unit 21. And a calibration relationship storage unit 44 storing as a calibration curve.
In the urine volume measurement control unit 43, the following processing is executed by a built-in program. First, the water pressure is measured by the water level measuring means 41 based on the measurement start instruction from the user, and the measured value is applied to the calibration curve stored in the calibration relationship storage unit 44 before the user excretes. It is processed (stored in RAM) as the amount of stored water before urination. Thereafter, the accumulated water pressure after the user completes excretion is measured, and the measured value is applied to the calibration curve stored in the calibration relationship storage unit 44 to obtain the post-urination retained water amount after the user completes urination. Process (store in RAM). Then, the difference between the pre-urination water amount and the post-urination water amount is obtained, and the difference value is calculated as the urination amount by the user.

The urine volume measurement control unit 43 not only measures the urine output by the user as described above, but also measures the accumulated water pressure per unit time after the measurement is started by the water level measuring means 41, and uses the measurement result as a calibration curve. You may have the program which calculates the change of the amount of stored water by applying. Since the change in the amount of accumulated water calculated in this way is a value indicating the amount of urination per unit time by the user, it can be used as data representing the excretion rate by the user.
These calculated values of urination volume and urination speed are displayed on a display unit (not shown) and stored in the urine volume measurement control unit 43. Then, the stored calculated value can be transmitted to a management center or the like using a wired or wireless communication means.

  The calibration curve stored in advance in the calibration relationship storage unit 44 can be used as the calibration curve, but it is preferable that the calibration curve can be individually rewritten. This is because when the flush toilet 2 is made of earthenware, the shape of the bowl portion 21 is different for each flush toilet 2, and the relationship between the stored water level and the amount of stored water also varies. In order to make it possible to rewrite, after the construction of the urine volume measuring toilet apparatus 1, a fixed amount of water is repeatedly put into the bowl portion 21 and the stored water pressure measured by the water level measuring means is repeatedly measured. This can be dealt with by calculating data and obtaining a calibration curve as an approximate expression of this multipoint data and storing it in the calibration relationship storage unit 44. Further, the calibration curve can be periodically rewritten by incorporating a metered water pump inside the measurement unit 40.

  Next, the shape of the cabinet 4 in the urine volume measuring toilet apparatus 1 will be described. FIG. 3 is a side view of a urine volume measuring toilet apparatus to which the present invention is applied.

  In FIG. 3, the toilet seat 30 is in a substantially horizontal state (closed state) placed on the flush toilet 2, and the toilet lid 31 is lifted upward and rotated rearward. . The cabinet 4 has a box shape in which the measurement unit 40 and the like are housed. The front surface 45 of the cabinet 4 faces the toilet lid main body 311 when the toilet lid 31 is open. . That is, the front surface 45 of the cabinet 4 extends in a substantially horizontal direction so that the surface above the lower side is rearward compared to the lower side up to the same height as the upper surface of the toilet seat box 3 on which the toilet lid 31 is pivotally supported. A stepped portion 451 is formed.

  The upper end of the toilet lid 31 in the opened state extends upward from the upper end of the cabinet 4, and the pivot point 313 in the toilet seat box 3 of the toilet lid 31 is located in front of the front surface 45 of the cabinet 4. Therefore, in the opened state of the toilet lid 31, the toilet lid body 311 is closest to the upper end of the front surface 45 of the cabinet 4, but the upper end of the closest front surface 45 is compared with the front surface 45 at the same height as the pivot 313. It is located rearward by the length of the step portion 451 in the front-rear direction. Accordingly, since the toilet lid body 311 of the toilet lid 31 can be tilted rearward with respect to the vertical, the toilet lid 31 can be made independent without pulling the pivot support point 313 of the toilet lid 31 with respect to the cabinet 4 forward. be able to. Therefore, the self-supporting state can be maintained when the toilet lid 31 is opened without increasing the length of the urine volume measuring toilet device 1 in the front-rear direction.

  In FIG. 3, one step portion 451 is formed on the front surface 45 of the cabinet 4, but the number of step portions 451 is not limited to one, and a plurality of step portions can be formed.

Next, a modified example of the urine volume measuring toilet apparatus 1 described in FIG. 3 will be described. FIG. 4 shows a modification of the embodiment of the present invention. The urine volume measuring toilet apparatus 1 shown in FIG. 4 is different from that shown in FIG. 3 in that the front surface 45 of the cabinet 4 does not have a stepped portion 451 and has an inclined surface 452 that is inclined upward from below. .
In FIG. 4, the front surface 45 of the cabinet 4 is flat and upwardly inclined, but may be upwardly inclined to a curved shape.

  Also in the urine volume measuring toilet apparatus 1 described in FIG. 4, the upper end of the toilet lid 31 in the opened state extends upward from the upper end of the cabinet 4, and the pivot point 313 in the toilet seat box 3 of the toilet lid 31. Is located in front of the front face 45 of the cabinet 4. Therefore, in the opened state of the toilet lid 31, the toilet lid body 311 is closest to the upper end of the front surface 45 of the cabinet 4, but the upper end of the closest front surface 45 is compared with the front surface 45 at the same height as the pivot 313. The upper end of the front surface 45 is located rearward by the inclined surface 452. Accordingly, since the toilet lid body 311 of the toilet lid 31 can be tilted rearward with respect to the vertical, the toilet lid 31 can be made independent without pulling the pivot support point 313 of the toilet lid 31 with respect to the cabinet 4 forward. be able to. Therefore, the self-supporting state can be maintained when the toilet lid 31 is opened without increasing the length of the urine volume measuring toilet device 1 in the front-rear direction.

  In particular, in the case of having the inclined surface 452 shown in FIG. 4, when the user turns over and leans on the toilet lid 31, the toilet lid body 311 and the front surface 45 of the cabinet 4 follow the inclined surface 452. Because of the wide contact, the force acting on the pivot fulcrum 313 of the toilet lid 31 can be reduced, and it can be prevented from being damaged or detached due to stress concentration near the pivot 313 of the toilet lid 31. It is.
