FIELD OF THE INVENTION

The present disclosure relates to a measuring device.

BACKGROUND OF THE INVENTION

A toilet apparatus with a body weight measuring function, in which a pressure sensor is installed on a lower surface of a toilet seat and which can measure the body weight of a user corresponding to a pressure value that is measured by the pressure sensor when the user sits on the toilet seat, has been proposed (refer to Patent Document 1).

Patent Document 1: Japanese Patent No. 3063245

SUMMARY OF THE INVENTION

However, in a case where it is desired to add a body weight measuring function to a toilet apparatus in the related art, there is a problem that it is necessary to replace a toilet seat thereof with a toilet seat (dedicated toilet seat) as described in Patent Document 1 in which a pressure sensor is installed.

In addition, a difference in height such as unevenness is likely to be generated on an upper surface of a pottery toilet bowl. Therefore, in the related art, a lower surface of a toilet seat is provided with a leg portion that is capable of being elastically deformed and the leg portion is installed on an upper surface of a toilet bowl so as to even out a difference in height of the upper surface of the toilet bowl. Accordingly, when installing a pressure sensor on the toilet bowl, the toilet seat, or the like, it is desired to avoid interference between the pressure sensor and the leg portion of the toilet seat.

Embodiments of the present invention have been made in consideration of the above-described circumstances. Provided is a measuring device which is capable of being installed without interfering with a leg portion of a toilet seat installed in a toilet apparatus in the related art and which is capable of measuring a body weight.

In order to achieve the above-described object, embodiments of the present invention adopt the following means.

In some embodiments, there is provided a measuring device which is configured to measure a body weight of a user sitting on a toilet seat, which is installed on a toilet bowl, and on which the toilet seat is installed, the device including a plurality of load measuring units that are configured to measure a load of the user acting on the toilet seat and that are disposed to protrude upward from an upper surface of the measuring device. The toilet seat can include a plurality of leg portions disposed to protrude downward from a lower surface of the toilet seat, a height from the upper surface to upper ends of the load measuring units is greater than a height from the lower surface of the toilet seat to lower ends of the leg portions, and the load measuring units are disposed at different positions from the leg portions as seen in plan view.

The measuring device configured as described above includes the load measuring units that are configured to measure the load of the user acting on the toilet seat and the measuring device is installed on the toilet bowl. In addition, the toilet seat is installed on the measuring device. Accordingly, it is possible to install the measuring device on the toilet bowl and use the toilet seat without replacement of the toilet seat installed in a conventional toilet apparatus.

In some embodiments, since the plurality of load measuring units provided to protrude upward from the upper surface of the measuring device and the plurality of leg portions provided to protrude downward from the lower surface of the toilet seat are disposed at different positions as seen in plan view, the load measuring unit and the leg portions do not interfere with each other as seen in plan view.

Furthermore, since the height from the upper surface of the measuring device to the upper ends of the load measuring units is greater than the height from the lower surface of the toilet seat to the lower ends of the leg portions, the load measuring units are capable of supporting the lower surface of the toilet seat and the lower ends of the leg portions are not supported by the upper surface of the measuring device. Therefore, it is possible to accurately measure the load of the user acting on the toilet seat.

In some embodiments, in the measuring device related to the first aspect, the plurality of load measuring units may be disposed to be separated from each other in a lateral direction. The leg portions may be disposed between the load measuring units on front and rear sides and the leg portions may be disposed behind the load measuring units on the rear side.

In the case of the measuring device configured as described, the leg portions are disposed between the load measuring units on the front and rear sides and the leg portions are disposed behind the load measuring units on the rear side. Accordingly, the load measuring units on the front and rear sides support the toilet seat while being dispersed. Therefore, the toilet seat is not bent downward and it is possible to more accurately measure the load of the user.

In some embodiments, the measuring device related to the first aspect or the second aspect may further include a urine sensor that includes an electrode electrolyzing urine and a control unit that is configured to operate the urine sensor and calculate an amount of a component contained in the urine according to a result of electrolysis performed by the electrode.

The measuring device configured as described has the urine sensor that includes the electrodes electrolyzing urine and the control unit that is configured to operate the urine sensor and calculate the amount of the component contained in urine according to the result of the electrolysis performed by the electrode. Accordingly, it is possible to measure not only the body weight of the user but also the amount of a desired component in urine.

In some embodiments, the measuring device related to any one of the first to third aspects may further include a handle that is configured to measure a body fat percentage and that is configured to be gripped.

Since the measuring device configured as described above includes the handle that is configured to measure a body fat percentage and that is configured to be gripped, it is possible to measure not only the body weight of the user but also the body fat percentage.

In some embodiments, in the measuring device related to any one of the first to fourth aspects, a first connection port that is electrically connected to a toilet seat box openably and closably supporting the toilet seat may be provided, and a second connection port that is electrically connected to an external power source may be provided.

In the case of the measuring device configured as described above, the first connection port that is electrically connected to the toilet seat box is provided, and the second connection port that is electrically connected to the external power source is provided. Therefore, it is possible to supply power to the measuring device and the toilet seat box by electrically connecting a connection port provided in an existing toilet seat box and the first connection port to each other and electrically connecting the second connection port and the external power source to each other. In an aspect in which no measuring device is installed, a cable connected to the connection port provided in the existing toilet seat box is connected to the external power source. When installing the measuring device, it is possible to supply power to the measuring device and the toilet seat box by removing the cable from the external power source, connecting the cable to the first connection port of the measuring device, and connecting a cable connected to the second connection port to the external power source.

In some embodiments, it is possible to install the measuring device without interfering with leg portions of a toilet seat installed on a conventional toilet apparatus and to measure a body weight.

As shown in FIG. 3, the toilet seat box 6 is installed on the measuring device 2 at a rear portion of the measuring device 2. The toilet seat box 6 includes a casing 61, various functional components (not shown) such as a toilet seat opening and closing mechanism that is disposed inside the casing 61 and opens and closes the toilet seat 8, a toilet lid opening and closing mechanism that opens and closes the toilet lid 9, and a private part cleaning device (cleaning function unit) that cleans private parts of a human body, and a main body control unit (not shown) that controls the various functional components.

As shown in FIG. 1, the cleaning water tank 7 is fixed onto the toilet bowl 1 at a position behind the toilet seat box 6. In the cleaning water tank 7, cleaning water for cleaning the toilet bowl 1 is stored.

The toilet seat 8 is formed to be approximately 0-shaped as seen in plan view. A rear portion thereof is pivotally supported by the toilet seat box 6 and the toilet seat 8 is capable of swinging relative to the toilet bowl 1 between an erected state and a lying state. The toilet seat 8 is installed on the measuring device 2 in the lying state (refer to FIG. 1).

FIG. 8 is a perspective view of the toilet seat 8 as seen from the lower side. FIG. 9 is plan view showing a disposition relationship between the load cell covers 27 of the measuring device 2 and leg portions 8e of the toilet seat 8 in the flush toilet 100.

As shown in FIG. 8, a plurality of the leg portions 8e are provided on a lower surface 8d of the toilet seat 8. In some embodiments, four leg portions 8e are disposed in a bilaterally symmetrical manner and are disposed to be separated from each other in the lateral direction.

As shown in FIG. 9, the load cell covers 27 and the leg portions 8e are disposed at different positions from each other as seen in plan view. In other words, the leg portions 8e on the front side are disposed between the load cell covers 27 on the front side and the load cell covers 27 on the rear side. The leg portions 8e on the rear side are disposed behind the load cell covers 27 on the rear side.

In addition, as seen in a side view shown in FIG. 2, a height from the upper surface 26u of the upper cover 26 of the measuring device 2 to the upper ends of the load cell covers 27 is greater than a height from the lower surface 8d of the toilet seat 8 to lower ends of the leg portions 8e. In other words, a height from the upper surface 26u of the upper cover 26 of the measuring device 2 to the upper ends of the load cell covers 27 in a direction in which the measuring device 2 and the toilet seat 8 are arranged is greater than a height from the lower surface 8d of the toilet seat 8 to lower ends of the leg portions 8e in a direction in which the measuring device 2 and the toilet seat 8 are arranged. Accordingly, the load cell covers 27 is capable of supporting the lower surface 8d of the toilet seat 8 and the lower ends of the leg portions 8e of the toilet seat 8 are not supported by the upper surface 26u of the upper cover 26 of the measuring device 2.

The toilet lid 9 is pivotally supported by the toilet seat box 6 and is capable of swinging relative to the toilet bowl 1 between an erected state and a lying state.

Next, an operation of the measuring device 2 in the flush toilet 100 configured as described above will be described.

When the user sits on the toilet seat 8, a sitting sensor (not shown) detects that the user has sat thereon. The urine measurement control unit 51 transmits a measurement position movement signal to the drive motor. Accordingly, the drive motor causes the urine sugar measuring sensor 30A, the urine salinity measuring sensor 30B, and the urine sensor covers 23 to move to the measurement positions from the accommodation positions. The grip portions 57 of the body fat measuring bodies 55 may be configured to move to the measurement positions from the accommodation positions according to the signal from the urine measurement control unit 51 at this time.

When the user urinates, each of the electrodes of the urine sugar measuring sensor 30A and the urine salinity measuring sensor 30B performs electrolysis. The urine measurement control unit 51 calculates urine sugar and urine salinity according to the result of the electrolysis.

Meanwhile, when the user sits on the toilet seat 8, loads act on the load cells 53. The loads are converted into electric signals by the load cells 53 and are transmitted to the urine measurement control unit 51. The urine measurement control unit 51 adds up the loads indicated by the electric signals to calculate the body weight of the user.

In addition, when the user grips the grip portions 57 of the body fat measuring bodies 55, the urine measurement control unit 51 causes a minute amount of electric current to flow toward the body and measures the resistance by using an impedance method or the like to measure the body fat percentage or the like.

The urine measurement control unit 51 may cause the result of the measurement to be displayed on a display unit (not shown).

In the case of the flush toilet 100 configured as described above, the measuring device 2, which includes the load cells 53 that are configured to measure the loads of the user acting on the toilet seat 8, is installed on the toilet bowl 1. In addition, the toilet seat 8 is installed on the measuring device 2. Accordingly, it is possible to install the measuring device 2 on the toilet bowl 1 and use the toilet seat 8 as it is without replacement of the toilet seat 8 installed on the conventional flush toilet 100.

In addition, since the plurality of load cells 53 provided to protrude upward from the upper surface 26u of the upper cover 26 of the measuring device 2 and the plurality of leg portions 8e provided to protrude downward from the lower surface 8d of the toilet seat 8 are disposed at different positions as seen in plan view (as seen in direction in which measuring device 2 and toilet seat 8 are arranged), the load cells 53 and the leg portions 8e do not interfere with each other as seen in plan view.

Furthermore, since a height from the upper surface 26u of the upper cover 26 of the measuring device 2 to the upper ends of the load cells 53 is greater than a height from the lower surface 8d of the toilet seat 8 to the lower ends of the leg portions 8e, the load cells 53 is capable of supporting the lower surface 8d of the toilet seat 8 and the lower ends of the leg portions 8e of the toilet seat 8 are not supported by the upper surface 26u of the upper cover 26 of the measuring device 2. Therefore, it is possible to accurately measure the loads of the user acting on the toilet seat 8.

In addition, the leg portions 8e are disposed between the load cells 53 on the front and rear sides and behind the load cells 53 on the rear side. Accordingly, the load cells 53 on the front and rear sides support the toilet seat 8 while being dispersed. Therefore, the toilet seat 8 is not bent downward and it is possible to more accurately measure the loads of the user.

In addition, the measuring device 2 includes the urine sensors 30 that include the electrodes capable of electrolyzing urine and the urine measurement control unit 51 that operates the urine sensors 30 and calculates the amount of components contained in urine according to the result of the electrolysis performed by the electrodes. Accordingly, it is possible to measure not only the body weight of the user but also the amount of a desired component in urine.

In addition, since the measuring device 2 includes the body fat measuring bodies 55 that are capable of measuring a body fat percentage and that are capable of being gripped, it is possible to measure not only the body weight of the user but also the body fat percentage.

In addition, the connection port 58a to which the cable H1 connected to the connection port of the toilet seat box 6 is connected and the connection port 58b to which the cable H2 connected to the external power source is connected are provided in the measuring device 2. Therefore, it is possible to supply power to the measuring device 2 and the toilet seat box 6 by electrically connecting a connection port provided in an existing toilet seat box and the connection port 58a to each other and electrically connecting the connection port 58b and the external power source to each other. In an aspect in which no measuring device 2 is installed, the cable H1 connected to the connection port provided in the existing toilet seat box 6 is connected to the external power source. When installing the measuring device 2, it is possible to supply power to the measuring device 2 and the toilet seat box 6 by removing the cable H1 from the external power source, connecting the cable H1 to the connection port 58a of the measuring device 2, and connecting the cable H2 connected to the connection port 58b to the external power source.

In addition, since the load cells 53 are covered by the load cell covers 27, the load cells 53 are not likely to be contaminated.
