Japanese Patent Laid-Open No. 9-119859

  However, since the weight scale for toilets of patent document 1 installs a weight sensor between the upper surface of a toilet bowl main body, and the lower surface of a toilet seat, there exists a possibility that urine, toilet bowl washing water, etc. may start. For this reason, the weight sensor which outputs the signal which converted the pressure into the electric signal needs to have waterproofness. Further, the weight sensor is repeatedly deformed depending on the weight of the user sitting on the toilet seat. For this reason, the weight sensor needs to have durability. Thus, since the weight sensor needs to have waterproofness and durability, it is not easy to reduce the size. When the weight sensor installed between the upper surface of the toilet bowl and the lower surface of the toilet seat becomes larger, the gap between the upper face of the toilet bowl and the lower surface of the toilet seat becomes larger, and urine, toilet flushing water, etc. scatter from the gap to the outside of the toilet bowl. There is a risk of malfunctions such as

  In addition, when the toilet body is made of earthenware, the level of the upper surface of the toilet body varies. For this reason, the weight sensor installed on the upper surface of the toilet body is not necessarily installed horizontally, and the direction in which the weight sensor detects the weight deviates from the direction of the weight of the user on the weight sensor. There is a risk that it will not be performed well. Furthermore, in recent years, the width of the toilet rim has been significantly narrowed in order to improve the design, and when a weight sensor is installed on the narrowed rim, the stability is impaired and detection is still not performed well. There is a fear.

  The present invention has been made in view of the above-described conventional circumstances, and is a toilet scale that can be favorably attached to a toilet and can measure a user's weight well, and a toilet equipped with the toilet scale. Providing is a problem to be solved.

The toilet scale of the first invention is a toilet scale attached to a toilet having a toilet body and a toilet seat, and measuring the weight of a user seated on the toilet seat,
It has a detection port for enclosing fluid and detecting internal pressure, and is installed between the upper surface of the toilet body and the lower surface of the toilet seat, and when the user sits on the toilet seat, it is compressed and deformed and the internal pressure is An increasing bag,
A holding member that holds the bag body by forming a groove part into which the bag body is fitted with a portion of the bag body exposed;
A pressure sensor communicating with the detection port and detecting an internal pressure of the bag;
And an arithmetic device for calculating the weight of the user based on the output of the pressure sensor.

  This toilet scale is calculated by calculating the weight of the user seated on the toilet seat from the internal pressure of the bag installed between the upper surface of the toilet body and the lower surface of the toilet seat, by the pressure sensor. can do. Since the bag body does not contain an electric device, it can be configured with a simple structure and has only to be durable. For this reason, a bag body can be reduced in size. Moreover, since the deformation of the bag body is not limited to one direction, the internal pressure increases according to the weight of the user even if the level of the upper surface of the toilet body varies. For this reason, this toilet scale can detect a user's weight favorably.

  Therefore, the toilet scale of the present invention can be favorably attached to the toilet, and the weight of the user can be measured well.

It is sectional drawing which shows the state which attached the toilet scale of Example 1 to the toilet bowl. It is principal part sectional drawing which shows the state which attached the toilet scale of Example 1 to the toilet bowl. It is a perspective view which shows the toilet scale of Example 1. FIG. It is the schematic which shows the structure of the toilet scale of Example 1. FIG. It is principal part sectional drawing which shows the state which attached the toilet scale of Example 2 to the toilet bowl.

  A preferred embodiment of the present invention will be described.

In the toilet scale of the first invention, the holding member is compressed and deformed when a part of the exposed bag body comes into contact with one of the upper surface of the toilet body or the lower surface of the toilet seat and the user sits on the toilet seat. The bag can be arranged as described above. In this case, the bag can be easily installed between the upper surface of the toilet body and the lower surface of the toilet seat by the holding member. Further, since the bag body is held by the holding member, no positional deviation occurs even if it is compressed and deformed.

In the toilet scale according to the first aspect of the present invention, the bag may be arranged to extend from side to side along the central opening of the toilet seat. In this case, since the bag body is arranged in a wide range with respect to the lower surface of the toilet seat, the bag body is compressed and deformed according to the weight of the user even if the seating position of the user on the toilet seat is slightly shifted left and right. And the internal pressure increases. For this reason, this toilet scale can detect a user's weight favorably.

The toilet scale according to the first aspect of the present invention may include a pump that allows fluid to flow into the bag. In this case, when the fluid in the bag body decreases with time, the pump can be driven to cause the fluid to flow into the bag body, whereby the bag body can be set to the set internal pressure.

The toilet scale according to the second invention is a toilet scale attached to a toilet having a toilet body and a toilet seat, and measuring the weight of a user seated on the toilet seat,
It has a detection port for enclosing fluid and detecting internal pressure, and is installed between the upper surface of the toilet body and the lower surface of the toilet seat, and when the user sits on the toilet seat, it is compressed and deformed and the internal pressure is An increasing bag,
A pump for allowing fluid to flow into the bag,
A pressure sensor communicating with the detection port and detecting an internal pressure of the bag;
And an arithmetic device that calculates the weight of the user based on the output of the pressure sensor,
The pump is driven by the rotation of the toilet seat to allow fluid to flow into the bag.
In this toilet scale , the pump is driven in conjunction with the rotation of the toilet seat, and the fluid can flow into the bag. For this reason, this toilet scale need not be provided with a separate handle or the like for driving the pump. In addition, since the pump is driven by the user turning the toilet seat, the fluid flows into the bag body without being conscious of the user, and the decrease of the fluid in the bag body over time can be suppressed.

  The toilet of this invention has a toilet bowl main body and a toilet seat, and was equipped with the said toilet scale. This toilet bowl can measure a user's weight favorably with the toilet scale attached favorably.

Next, Examples 1 and 2 in which the toilet scales of the first invention and the second invention are embodied will be described with reference to the drawings.

<Example 1>
As shown in FIG. 1, the toilet scale 20 according to the first embodiment is attached to the toilet 10 and measures the weight of the user H seated on the toilet seat 12. The toilet 10 includes a toilet main body 11, a toilet seat 12, a toilet lid 13, a toilet seat box 14, a cleaning tank 15, a cleaning moisture pipe 16, and a drainage connection pipe 17. The toilet body 11 includes a toilet bowl portion 11A and a toilet drainage channel communicating with the downstream side of the toilet bowl portion 11A. The toilet seat 12 and the toilet lid 13 are pivotally supported by the toilet seat box 14, and are rotatable between a standing state and a lying state with respect to the toilet body 11. The toilet seat box 14 is mounted on a holding member 22 which will be described later, on the toilet main body 11 behind the toilet bowl 11A and ahead of the washing tank 15. This toilet seat box 14 houses an arithmetic unit 26, a pump 27, and the like which will be described later. The washing tank 15 is placed and fixed on the rear upper surface of the toilet body 11. This washing tank 15 stores washing water for toilet bowl washing. The cleaning water pipe 16 communicates with a discharge port provided on the lower surface of the cleaning tank 15 and has two water discharge ports 16A branched so as to discharge the cleaning water at two places on the upper peripheral edge of the toilet bowl 11A. doing. When the toilet bowl 10 is subjected to toilet cleaning, the cleaning water stored in the cleaning tank 15 is discharged from two places on the upper peripheral edge of the toilet bowl 11A through the cleaning moisture pipe 16. The drainage connection pipe 17 connects the downstream end of the toilet drainage channel 11B and the upstream end of the drainage pipe 1 drawn out from the floor surface F.

  As shown in FIGS. 1 to 4, the toilet scale 20 includes a bag body 21, a holding member 22, a manifold 24, a pressure sensor 25, a calculation device 26, a pump 27, and a relief valve 28. The bag body 21 is made of rubber, and is formed so as to be a cylindrical body having a substantially U-shaped outer shape in a state where both ends are closed and air that is a fluid is sealed. The bag body 21 has a detection port 21A penetrating on the rear side surface of the central portion. The detection port 21A is used to detect the internal pressure of the bag body 21. The detection port 21 </ b> A also serves as an inflow port through which air as a fluid flows into the bag body 21. As will be described later, the bag body 21 is fitted and held in the groove portion 23 of the holding member 22 with the upper side surface exposed from the upper surface of the holding member 22 over the entire length. That is, the holding member 22 holds the bag body 21 with a part of the bag body 21 exposed.

  The holding member 22 is placed on the upper surface of the toilet body 11 on the front side (the toilet bowl portion 11 </ b> A side) of the cleaning tank 15. When the holding member 22 is placed on the upper surface of the toilet body 11 and viewed from above the toilet body 11, the outer shape is formed to be substantially the same as the outer shape of the upper surface of the toilet body 11. Further, the holding member 22 is opened on the inner side of the upper opening 18 of the toilet bowl 11A in a state of being placed on the upper surface of the toilet body 11, and is similar to the upper opening 18 of the toilet bowl 11A. It has a part 22A. The holding member 22 has a hanging edge 22B that hangs down from the periphery of the opening 22A. When the holding member 22 is placed on the upper surface of the toilet body 11, the hanging edge portion 22 </ b> B is located on the inner side of the upper opening 18 of the toilet bowl 11 </ b> A and extends downward from the upper surface 19 of the toilet body 11.

  The holding member 22 forms a groove portion 23 opened upward on the upper surface side in a state of being placed on the upper surface of the toilet body 11. The groove portion 23 extends rearward from the left and right front portions of the holding member 22 along the periphery of the opening 22A, and is connected to the rear of the opening 22A. The groove 23 is formed in a substantially U shape when viewed from above. The groove part 23 is formed in the cross-sectional shape (circle shape which notched about 1/4 of the upper side notch) according to the side surface of the bag body 21 which enclosed air with the set internal pressure (refer FIG. 2).

  The holding member 22 fits the bag body 21 in the groove 23 and holds the bag body 21 so that the upper side surface of the bag body 21 is exposed from the upper surface of the holding member 22 over the entire length of the bag body 21. Since the opening width of the groove portion 23 is narrower than the diameter of the bag body 21 filled with air at the set internal pressure, the bag body 21 is held so as not to come out of the groove portion 23.

  The manifold 24 has a first port 24A to a fourth port 24D. The first port 24A of the manifold 24 communicates with the detection port 21A of the bag body 21. The pressure sensor 25 communicates with the second port 24B of the manifold 24. For this reason, the pressure sensor 25 communicates with the bag body 21 via the manifold 24 and can detect the internal pressure of the bag body 21. The pressure sensor 25 outputs an electrical signal according to the detected internal pressure.

  The calculation device 26 receives the signal output from the pressure sensor 25 and can convert the force of compressing and deforming the bag body 21 into a weight according to the input signal. That is, the bag body 21 is disposed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12 so that the user H sits on the toilet seat 12 so that the bag body 21 is compressed and deformed to increase the internal pressure. In this case, the pressure sensor 25 detects the pressure of the bag body 21, and the computing device 26 can compute the weight of the user H seated on the toilet seat 12 according to the output of the pressure sensor 25. The computing device 26 is housed in the toilet seat box 14. The computing device 26 outputs the computed result to a display device (not shown) provided in the toilet seat box 14 or the like. The display device displays the weight of the user H seated on the toilet seat 12.

  The pump 27 communicates with the third port 24 </ b> C of the manifold 24 through a connection tube 29. The pump 27 is housed in the toilet seat box 14, and the shaft portion 27 </ b> A is connected to the shaft portions of the toilet seat 12 and the toilet lid 13. For this reason, when the user H or the like of the toilet bowl 10 rotates the toilet seat 12 and / or the toilet lid 13 between the standing state and the lying state, the shaft of the pump 27 connected to the shaft portion of the toilet seat 12 and the toilet lid 13. The portion 27 </ b> A rotates and air is sent out in the direction of the manifold 24 through the connection tube 29. The air sent from the pump 27 toward the manifold 24 flows into the bag body 21 from the first port 24A of the manifold 24 through the detection port 21A of the bag body 21. As described above, the toilet scale 20 does not have to be provided with a handle for driving the pump 27 or the like. In addition, since the pump 27 is driven when the user H rotates the toilet seat 12 and / or the toilet lid 13, air flows into the bag body 21 without being conscious of the user H, and the inside of the bag body 21. A decrease in air over time can be suppressed.

  The relief valve 28 communicates with the fourth port 24 </ b> D of the manifold 24. The relief valve 28 is set to open when the air flows into the bag body 21 by the pump 27 and the internal pressure of the bag body 21 becomes higher than the set pressure, and the rest is closed. As a result, the toilet seat 12 and / or the toilet lid 13 rotate to prevent the air from flowing into the bag body 21 and the internal pressure of the bag body 21 from exceeding the set pressure.

  In the toilet scale 20 having such a configuration, the holding member 22 is placed on the upper surface of the toilet body 11 on the front side of the washing tank 15 (toilet bowl 11A side). The toilet seat box 14 is attached to the rear upper surface of the holding member 22. The bag body 21 is held with the upper side surface exposed in a groove 23 formed along the opening 22 </ b> A of the holding member 22. For this reason, when the toilet seat 12 that is pivotally supported by the toilet seat box 14 is positioned on the holding member 22, the lower surface of the toilet seat 12 comes into contact with the upper side surface of the bag body 21. Further, the bag body 21 is arranged to extend from side to side and front and rear along the central opening 12 </ b> A of the toilet seat 12. That is, the bag body 21 is held by the holding member 22 and is installed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12.

  And when the user H seats on the toilet seat 12, the bag body 21 will compress-deform and an internal pressure will increase. Then, the pressure sensor 25 detects the internal pressure of the bag body 21, and outputs an electrical signal corresponding to the internal pressure. Then, the calculation device 26 receives the electrical signal output from the pressure sensor 25 and calculates the weight of the user H seated on the toilet seat 12 according to the input signal. The toilet scale 20 displays the weight of the user H seated on the toilet seat 12 as a calculation result on the display device.

  In this way, the toilet scale 20 is seated on the toilet seat 12 from the internal pressure of the bag body 21 that is installed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12 by the pressure sensor 25 detecting the internal pressure. The weight of the user H can be calculated and measured. Since the bag body 21 does not contain an electric device, it can be configured with a simple structure and has only to be durable. For this reason, the bag body 21 can be reduced in size. Moreover, since the deformation of the bag body 21 is not limited to one direction, the internal pressure increases according to the weight of the user H even if the level of the upper surface of the toilet body 11 varies. For this reason, this toilet scale 20 can detect the weight of the user H satisfactorily.

  Therefore, the toilet scale 20 of the first embodiment can be favorably attached to the toilet 10, and the weight of the user H can be measured well.

  The toilet scale 20 holds the holding member 22 in a state where the upper side surface of the bag body 21 is exposed, the exposed upper side surface of the bag body 21 abuts on the lower surface of the toilet seat 12, and the toilet seat 12 is in contact with the user. The bag body 21 is arranged so as to be compressed and deformed when H is seated. For this reason, the bag 21 can be easily installed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12 by the holding member 22. Further, since the bag body 21 is held by the holding member 22, no positional deviation occurs even if it is compressed and deformed.

  Further, the toilet scale 20 has a bag body 21 extending along the central opening 12 </ b> A of the toilet seat 12 to the left and right and front and rear. For this reason, the bag body 21 is arranged in a wide range with respect to the lower surface of the toilet seat 12, and the bag body according to the weight of the user H even if the seating position of the user H on the toilet seat 12 is slightly shifted left and right. 21 is compressed and deformed, and the internal pressure increases. For this reason, this toilet scale 20 can detect the weight of the user H satisfactorily.

  In addition, when the air in the bag body 21 decreases, the toilet scale 20 drives the pump 27 to rotate the toilet seat 12 and / or the toilet lid 13 so that fluid flows into the bag body 21. Thus, the set internal pressure of the bag body 21 can be set.

<Example 2>
As shown in FIG. 5, the toilet scale 120 according to the second embodiment is different from the first embodiment in the holding member 122. Other configurations are the same as those in the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  The holding member 122 according to the second embodiment forms a groove portion 123 that opens downward on the lower surface side while being placed on the upper surface of the toilet body 11. The groove portion 123 extends rearward from the left and right front portions of the holding member 122 along the periphery of the opening 22A, and is connected to the rear of the opening 22A. The groove part 123 is formed in a substantially U shape when viewed from below. The groove portion 123 is formed in a cross-sectional shape (a circular shape in which about one-fourth of the lower side is cut out) according to the side surface of the bag body 21 in which air is sealed with a set internal pressure.

  The holding member 122 fits the bag body 21 into the groove portion 123 and holds the bag body 21 so that the lower side surface of the bag body 21 is exposed from the lower surface of the holding member 22 over the entire length of the bag body 21. Since the opening width of the groove portion 123 is narrower than the diameter of the bag body 21 filled with air at the set internal pressure, the bag body 21 is held so as not to come out of the groove portion 123.

  In the toilet scale 120 having such a configuration, the holding member 122 is placed on the upper surface of the toilet body 11 on the front side (the toilet bowl portion 11A side) of the washing tank 15. As a result, the upper surface of the toilet body 11 comes into contact with the lower side surface of the bag body 21. The toilet seat box 14 is attached to the rear upper surface of the holding member 22. Then, the bag body 21 is disposed so as to extend left and right and front and rear along the central opening 12 </ b> A of the toilet seat 12. That is, the bag body 21 is held by the holding member 122 and installed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12.

  And when the user H seats on the toilet seat 12, the bag body 21 will compress-deform and an internal pressure will increase. Then, the pressure sensor 25 detects the internal pressure of the bag body 21, and outputs an electrical signal corresponding to the internal pressure. Then, the calculation device 26 receives the electrical signal output from the pressure sensor 25 and calculates the weight of the user H seated on the toilet seat 12 according to the input signal. The toilet scale 20 displays the weight of the user H seated on the toilet seat 12 as a calculation result on the display device.

  In this way, the toilet scale 120 is seated on the toilet seat 12 from the internal pressure of the bag 21 that is installed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12 by the pressure sensor 25 detecting the internal pressure. The weight of the user H can be calculated and measured. Since the bag body 21 does not contain an electric device, it can be configured with a simple structure and has only to be durable. For this reason, the bag body 21 can be reduced in size. Moreover, since the deformation of the bag body 21 is not limited to one direction, the internal pressure increases according to the weight of the user H even if the level of the upper surface of the toilet body 11 varies. For this reason, this toilet scale 120 can detect the weight of the user H satisfactorily.

  Therefore, the toilet scale 120 of the second embodiment can be favorably attached to the toilet 10, and the weight of the user H can be measured well.

  Further, the toilet scale 120 holds the holding member 122 in a state where the lower side surface of the bag body 21 is exposed, the exposed lower side surface of the bag body 21 abuts on the upper surface of the toilet body 11, and the toilet seat 12. When the user H is seated on the bag body 21, the bag body 21 is arranged so as to be compressed and deformed. For this reason, the bag member 21 can be easily installed between the upper surface of the toilet body 11 and the lower surface of the toilet seat 12 by the holding member 122. Further, since the bag body 21 is held by the holding member 122, no positional deviation occurs even if it is compressed and deformed.

  Further, the toilet scale 120 is arranged such that the bag body 21 extends left and right and front and rear along the central opening 12 </ b> A of the toilet seat 12. For this reason, the bag body 21 is arranged in a wide range with respect to the lower surface of the toilet seat 12, and the bag body according to the weight of the user H even if the seating position of the user H on the toilet seat 12 is slightly shifted left and right. 21 is compressed and deformed, and the internal pressure increases. For this reason, this toilet scale 120 can detect the weight of the user H satisfactorily.
