DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of a body fat meter for estimating a fat percentage of a human body.

[0002]

2. Description of the Related Art Conventionally, when measuring body fat percentage using infrared light, calibration is performed by inserting a detector (probe) into a reflector whose reflectance is known before each measurement. After that, a detector is known in which a detector is applied to the upper arm of the dominant arm, and a light-shielding band is attached to prevent intrusion of disturbance light during measurement.

[0003]

The technique described in the prior art has a problem that the calibration must be performed by inserting a probe into a reflector before each measurement, which is complicated. Was. In addition, it is difficult to make the measurement points constant, and there is a problem that the operability is not good, for example, it is necessary to shield light with a light shielding band.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention , a body fat percentage is calculated for a toilet seat.

The body fat percentage is calculated by a body fat meter provided on the toilet seat.
And the body facing the toilet seat of the toilet lid
That the reflector for the calibration of the fat scale was installed
Features. In claim 2, the body fat percentage is calculated for the toilet seat.
A body fat meter for the user and the size of the user sitting on the toilet seat
The body fat percentage of the thigh is calculated by the body fat meter provided on the toilet seat.
And the calibration of the body fat meter

[0005]

The calibration is automatically performed, and the body fat percentage is calculated at a constant point on the thigh while sitting on the toilet seat. In addition, the body fat percentage can be calculated at the same time as each operation at the time of washing or bathing.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a toilet provided with an arrangement structure of a body fat meter according to claim 1, FIG. 2 is an enlarged sectional view taken along line AA of FIG. 1, and FIG.

The toilet 1 is provided with a box portion 2 on the rear upper surface, which accommodates a low tank and an advance / retreat mechanism of a local cleaning device.
The operation box 3 is arranged on the left side of the figure, and the finger sphygmomanometer 4 and an IC card insertion section (not shown) are arranged on the right side of the toilet 1.
On the upper surface of the operation box 3, operation switches 5 and a display unit 6 are provided.
Are arranged. Further, a toilet seat 7 and a toilet lid 8 are rotatably mounted on the toilet 1, and a gear motor unit 9 in which a rotating shaft is fitted to a connecting portion between the toilet seat 7 and the toilet lid 8 is mounted in the box portion 2.

The toilet seat 7 is provided with a detector (probe) 10 of a body fat meter and a seating sensor 12 at a position where the thigh of the toilet seat 7 contacts when the user sits down.
The seating sensor 12 may be an electrostatic or pressure-sensitive pressure sensor mounted on the toilet seat 7, or may be a transmission or reflection-type photoelectric sensor that detects a seating state. When the toilet seat 7 is raised or the toilet lid 8 is closed, the detector 10
A reflector 11 for calibration is attached to a portion opposite to. Reference numeral 13 denotes a cleaning nozzle mounted on an advance / retreat mechanism of the local cleaning device.

When the seat is not seated, the toilet seat 7 is self-supported by an opening / closing damper (not shown) so as to contact the toilet lid 8 in an open state. At this time, calibration can be performed by the detector 10 attached to the toilet seat 7 and the reflector 11 attached to the toilet lid 8, so that measurement is possible at any time. When sitting down, the gear motor unit 9 is driven to rotate the toilet seat 7 and set on the toilet 1. Note that when the toilet 1 is not used, the toilet lid 8 is closed and calibration can be performed, so that the measurement can be performed at any time. The toilet lid 8 can be driven to open.

As shown in FIG. 2, a heater wire 1 for maintaining the toilet seat 7 at a desired temperature is provided on a surface portion 7a constituting the toilet seat 7.
5 is wired. Further, the control unit 16 of the body fat meter together with the detector 10 can be mounted on the back surface portion 7b constituting the toilet seat 7, but may be arranged in the operation box 3.

In the above, in order to calculate the body fat percentage,
First, when the user presses a predetermined switch of the operation switches 5, the self-standing toilet seat 7 is rotated by the gear motor unit 9 and set on the toilet 1. Then, when the user sits on the toilet seat 7, the seating sensor 12 detects the seating state and starts measurement after a lapse of a predetermined time.

As shown in FIG. 3, the body fat meter emits infrared light 21 from the light emitting element 10a of the detector 10, and a predetermined frequency of the infrared light 21 reflected inside the thigh 20 of the user. In order to measure the light amount in this band, the first light receiving element 10c receives the light through the first filter 10b that allows only the infrared light 21 in this frequency band to pass therethrough. The light is received by the second light receiving element 10e via the second filter 10d that allows only the external light 21 to pass. Further, 10c and 10e may be light emitting elements and 10a may be light receiving elements. Then, each received light amount and the aforementioned I
Data of the user's weight, height, physique, daily exercise, etc., which have been input in advance to the IC card inserted into the C card insertion section
The control unit 16 calculates the body fat percentage from the data by using a predetermined calculation formula. Note that the above data may be directly input by the operation switches 5.

The calculation result is displayed on the display unit 6 by digitally displaying the body fat percentage together with the weight as a percentage, or by displaying the body fat percentage digitally as a percentage and displayed in five stages. After use, when the user stands on the toilet seat 7, the seating sensor 12 detects that the user is not seated, and after a predetermined time elapses, the toilet seat 7 becomes independent by the opening / closing damper.

FIG. 4 is a perspective view of a wash basin provided with the arrangement structure of the body fat scale of the reference example . Detector 1 constituting body fat meter
0 is mounted on the side surface of the storage box 31 of the sink 30, and the control unit 16 is disposed inside the storage box 31. The user can measure the body fat percentage when using the sink.

FIG. 5 is a perspective view of a bath provided with an arrangement structure of a body fat scale according to another reference example . The detector 10 constituting the body fat meter is installed on the bottom of a bath (bathtub) 40,
The user can measure the body fat percentage while taking a bath.

FIGS. 6A and 6B are cross-sectional views of a toilet seat on which a body fat meter arrangement structure according to claim 3 is provided. FIG. 6A shows a state in which calibration is possible, and FIG. 6B shows a state in which measurement is possible. A motor 50 is provided inside the toilet seat 7 and on the back surface 7b constituting the toilet seat 7 together with the detector 10 and the control unit 16 of the body fat meter, and the pinion 52 and the rack are The reflector 53 for calibration is mounted on the tip of the rack 53.

When the user is not seated, the reflector 11 is opposed to the detector 10 as shown in FIG. 6A, so that calibration can be performed at any time. When the user sits on the toilet seat 7, the sitting sensor 12 detects the sitting state, and the body fat meter performs calibration based on the detection signal. Thereafter, the driving circuit (not shown) drives the motor 50 for a predetermined time to retract the reflector 11 from a position facing the detector 10 as shown in FIG. Further, after a predetermined time has elapsed, the same measurement as described above is started.

[0018]

As described above, according to the present invention, the operability of the body fat meter is improved, and an accurate body fat percentage can be known, which is effective as an index for health management.
