DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device incorporating a body fat meter for estimating the 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 provided for preventing disturbance light from entering 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. Therefore, if the body fat percentage is measured with the thighs before sitting on the toilet seat to add extra energy by attaching the detector to the toilet seat, the need to apply the detector to a predetermined measurement point or to shield the light from the light is eliminated, and operability is reduced. Is improved. However, since the toilet seat is provided with a heater wire for keeping heat, noise caused by turning on and off the power supply to the heater wire adversely affects the detector, and the toilet seat itself is a movable body that repeats opening and closing operations. Has a problem that the handling of the data becomes complicated.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a toilet seat device according to the present invention is provided.
Equipped with a body fat meter to measure body fat percentage at the barrel,
Equipped with a heater that maintains the temperature at a predetermined level,
Equipped with a seat sensor, based on a seat detection signal from the seat sensor
Turn off the power to the heater and complete the measurement from the body fat meter.
Characterized by restarting energization of the heater by an end signal.
You. That is, the heater is not energized during measurement by the detector. Also, the signal line of the body fat meter and the power of the heater
Separate from the cable and configure the signal cable with a flat cable.
Was.

[0005]

In accordance with the seating detection signal from the seating sensor,
The power supply to the heater is cut off and the measurement from the body fat meter is performed.
The energization to the heater is restarted by the fixed end signal, so that noise due to ON / OFF of energization to the heater is not mixed into the body fat meter . In addition, the flat cable
So as not to disturb the time of opening and closing the toilet seat by using
To

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 a toilet seat device according to the present invention, and FIG. 2 is an enlarged sectional view taken along line AA of 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.

When both the detection unit 10 and the control unit 16 of the body fat meter are built in the toilet seat 7 or the control unit 16 is
Even if it is arranged inside, the wiring from the detector 10 or the control unit 16 to the operation box 3 is separated from the power line to the heater wire 15 and, as shown in FIGS.
8 and is pulled out from the back surface portion 7b of the toilet seat 7 and connected to the operation box 3. By using the flat cable 18, even if the opening and closing operations of the toilet seat 7 are repeated, the disconnection and the standing of the toilet seat 7 are not hindered.

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. When the user sits on the toilet seat 7, the seating sensor 12 detects the seating state and starts measurement after a predetermined time has elapsed. At this time, the heater wire 15
Is in the energized state, as shown in FIG. 3, when the current 20 is alternating current, the energization is cut off at the zero crossing point immediately after the seating detection signal is output from the seating sensor 12, and after a predetermined time measurement, Then, the energization of the heater wire 15 is started again by the measurement end signal from the control unit 16 of the body fat meter.

According to the present invention, as described above, according to the present invention, flights
Body fat percentage at the position where the thighs hit when sitting
A body fat meter that measures
And a seating sensor for detecting a seating state.
