Has a function of flowing a constant current through each current applying electrode. The difference circuit 16 has a function of outputting a signal corresponding to a potential difference between the voltage supplied to the plus electrode and the voltage supplied to the minus electrode. At this time, since the constant current generation circuit 13 is used as a current source as described above, the potential difference is determined by the impedance of the human body, and the difference circuit 16 acts to measure the impedance of the human body. It is. An A / D converter 17 is connected to the output of the difference circuit 16, A / D converts a measured value indicating the impedance of a human body, and outputs the converted value to a microcomputer 18.

Table 1 shows the relationship between the impedance of the human body and the amount of body fat examined by the inventors.

[0018]

[Table 1]

The coefficients K1, K shown in Table 1
2, K3, K4 and K5 are determined by gender, age, weight and height. The body fat mass is calculated by the coefficient K
Using 1, K2, K3, K4, and K5, (Equation 1),
It is determined by the equation shown in (Equation 2).

Fat-free mass = K1 + K2 × W + K3 × Z + K4 × L × L / Z + K5 × A W: Weight, L: Height, Z: Impedance, A: Age (Equation 1) Body fat mass = Weight−Heat-free mass (Number) 2) Hereinafter, the operation of this embodiment will be described. The user opens the toilet lid 2, lowers the handrail portion 6, and uses the handrail portion 6 as an aid to sit on the toilet seat 3 and perform an excretory action. Toilet seat 3
When sitting on top, the user's buttocks or thighs will have electrodes 7e,
It contacts the electrode 7f, the electrode 7g, and the electrode 7h. Further, both arms of the user are in contact with the electrodes 7a, 7b, 7c and 7d. When the body fat key 20e provided on the operation means 4 is pressed during this excretion behavior, the microcomputer 18 starts the work of measuring the body fat percentage.

That is, the microcomputer 18 outputs a 50 kHz square wave pulse, and the constant current generating circuit 13 operates to convert the square wave pulse into a sine wave through a filter, thereby generating a constant current of 800 uA and 50 kHz. The signal of the microcomputer 18 is transmitted to the electrode switching unit 12,
The electrode switching unit 12 determines to which of the electrodes 7a to 7h the current flows. The impedance between the electrodes is measured using a four-terminal method in which the contact resistance is negligible. A current is applied to one electrode, and the potential of the other electrode paired with the electrode is measured. The potential between each pair of electrodes is determined by a difference circuit 16.
And the difference circuit 16 obtains the potential difference V between the electrodes. The signal indicating the potential difference V is supplied to the A / D converter 17.
Is converted into a digital signal and transmitted to the microcomputer 18. The microcomputer 18 determines the impedance between the electrodes, that is, the impedance of the human body, based on the digital signal.

The impedance at this time is Z = I / V
(I: constant current, V: potential difference). However, since the constant current I is affected by temperature and the like, in this embodiment, Z is calculated using the equation shown in (Equation 3). I'm asking.

Z = Ki × T + Ko (Ki: constant, Ko: constant) (Equation 3) Ki and Ko are stable reference resistances R1 (14) and R2 (15) whose resistance values are known. Is what you are looking for. Thus, in this embodiment, the impedance Z is obtained by the equation shown in (Equation 4).

Z = ((R1-R2) / (V1-V2)) × (V1 × R2-V2 × R1) / (V1-V2) (Equation 4) Next, the operation of the electrode switching unit 12 will be described. There are six measurement modes for the electrodes 7a to 7h. That is, mode 1 is between the reference resistors R1, mode 2 is between the reference resistors R2, mode 3
Is between right hand and left hand, Mode 4 is between right hand and left hip, Mode 5
Is between the left hand and the right buttocks, and mode 6 is between the right buttocks and the left buttocks. The microcomputer 18 sends a signal to the electrode switching unit 12 to
The impedance between the electrodes is measured by sequentially switching the six types of measurement modes at intervals of 100 ms.

As shown in FIG. 5, the measured impedance in mode 3 is Z3, the measured impedance in mode 4 is Z4, the measured impedance in mode 5 is Z5,
Assuming that the measured impedance in mode 6 is Z6, the impedance Z of the body is obtained by the equation shown in (Equation 5).

Z = (Z4 + Z5-Z3-Z6) / 2 (Equation 5) The impedance Z shown in (Equation 5) is similar to the impedance Z shown in (Equation 1), and is directly related to obesity. It is the impedance of visceral fat that is easily related and change.

In this way, the microcomputer 18 calculates the above (Equation 1),
The body fat mass is calculated based on (Equation 2), and the body fat mass is divided by the body weight to calculate the body fat percentage. At this time, the user inputs data of his / her gender, weight, height, and age using the operation means 4. This data input is performed as follows. First, at the time of initial setting, the personal setting key 20b of the operation means 4 is pressed to set the personal number 1. The display means 5 displays the personal number 1. Next, when the height key 20a of the operation unit 4 is pressed, a default value of the height, for example, 160 is displayed on the display unit 5. This default value is adjusted using the shift key 20c or 20d. Shift key 20c or 20
d can be increased or decreased by one each time the button is pressed. When the adjustment is completed in this way, the registration is performed by pressing the confirmation key 20f. Similarly, the weight, age, and gender are also registered. Each of the registered data is called up only by pressing the personal setting key 20b.

As described above, when the user sits on the toilet seat 3 and presses the body fat measurement key 20e of the operation means 4, the measurement start state is entered. After about 2 seconds of waiting time,
A pulse of 50 kHz is output from the microcomputer 18, a current starts to flow from the selected current applying electrode to the electrode, and measurement is started. One data capture time is 400 ms. After capturing 10 times, the last 5 data are averaged and displayed. The calculated body fat value is stored in the memory 19.
Is stored. In this embodiment, at this time, it is evaluated whether the user's exercise amount is sufficient. This exercise amount is evaluated by a pedometer. At the time of setting the height, weight, etc., the user presses the step count key 20g of the operation means 4 and the default of the step value displayed on the display means 5, for example, 10
000 steps in the same manner as above
Adjustment is performed using d, and registration is performed by pressing the confirmation key 20f.

When the number-of-steps key 20g and the graph key 20h are simultaneously pressed, the display means 5 displays the four-key as shown in FIG.
A step count graph for zero times is displayed. 1000 in the graph
A dot is displayed on the line of the zero step. Press the reset key (not shown) to reset the graph. Unless the reset key is pressed, the data is updated, and after 40 times, the data is deleted from the leftmost data. If you enter it once a day, you can see the results for about one month in a graph at a glance. When the user presses the calorie key 20i, the latest calorie consumption is displayed. The calorie consumption is
This is determined by a table previously input into the microcomputer 18, and is determined by the weight value and the number of steps. That is, the calorie consumption is about 300 kcal per 10,000 steps of exercise per day, and based on this, the calorie consumption of the user can be determined.

It is also known that a calorie consumption of 700 kcal is required to reduce the body fat amount of the human body by 100 g. Therefore, the microcomputer of the present embodiment can recognize the necessary calorie consumption in returning the body fat mass of the user to the standard value, and determine whether the current exercise amount of the user is sufficient for this. Is also something that can be done.

As described above, according to the present embodiment, a plurality of electrodes 7a to 7h provided on the toilet seat 3 and the handrail portion 6, and a resistance value measuring means for flowing a current between the electrodes and measuring a resistance value between the electrodes. 8, operation means 4 for inputting weight, height, age, gender, and step value of a pedometer, and display means 5 for displaying measurement results
And a calculating means 9 for calculating a body fat value and a calorie consumption from the information of the resistance value measuring means 8 and the operation means 4 and displaying a time course of the calculated value on the display means 5. As a configuration, based on the measured impedance of the visceral fat and the information input to the operation means 4, the time course of the body fat value and the calorie consumption amount, and whether the calorie consumption amount is sufficient for the current body fat value It is an object of the present invention to realize a toilet seat device with a body fat measurement function capable of displaying whether or not the toilet seat device has a body fat measurement function.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 6 is a perspective view showing the configuration of the operating means 4 used in the toilet seat device with body fat measurement function of the present embodiment. In the present embodiment, the operation means 4 includes a reading unit 25 for reading the count value of the pedometer. FIG. 7 is a perspective view showing the configuration of the pedometer used in this embodiment. Pedometer 2 used in this embodiment
1 has a reset button 22 and an electrode 23.

When the user stores the used pedometer 21 in the reading section 25 of the operating means 4, the electrodes provided in the reading section 25 come into contact with the electrodes 23 of the pedometer 21 and the pedometer 21 counts. The value 10258 is read. The operating means 4 stores the read value in the memory 19.
To memorize. When the data reading is completed, the operation means 4
Indicates on the display means 5 that the data reading has been completed.

As described above, according to the present embodiment, the operating means 4 is provided with the reading section 25 for reading the count value of the pedometer, and the data can be displayed by reading the count value of the pedometer simply by inserting the pedometer. As a configuration, an easy-to-use toilet seat device with a body fat measurement function that can automatically read data of a pedometer is realized.

(Embodiment 3) Next, a third embodiment of the present invention will be described. In this embodiment, a charging battery is provided in the reading unit 25 described in the second embodiment. With the above configuration, when the user accommodates the pedometer 21 shown in FIG. 7 in the reading unit 25, the operation unit 4 automatically reads the data of the pedometer 21 in the same manner as in the second embodiment. The microcomputer 18 detects the remaining battery level of the pedometer 21. If the remaining amount at this time is less than the predetermined value,
The battery is charged through the electrode 23 by a built-in charging battery.

As described above, according to the present embodiment, the operating means 4 can automatically read the count value of the pedometer 21 and charge the pedometer 21 to prevent the pedometer from running out of battery. This realizes an easy-to-use toilet seat device with a body fat measurement function. And the power is automatically supplied to the step counting means, so that it is possible to prevent the battery from being forgotten.

(Embodiment 4) Next, a fourth embodiment of the present invention will be described. FIG. 8 is a perspective view showing the configuration of this embodiment. In this embodiment, a pressure sensor 28 is provided on the toilet seat 3. In this embodiment, four strain gauges are used as the pressure sensor 28. The strain gauge generates a voltage signal that is applied or changes linearly with weight, as shown in FIG. Therefore, the pressure sensor 28
Generates a voltage as shown in FIG. 9 when a user sits on the toilet seat 3.

Therefore, according to the present embodiment, the weight of the user can be automatically measured. In this embodiment, when the pressure sensor 28 is used as a weight scale, the accuracy of the weight measurement is set to ± 200 g, which is 0.2% of the maximum load of 100 kg. FIG. 10 is a block diagram showing the configuration of this embodiment. The signal from the pressure sensor 28 is switched by a weight / body fat switching unit 29, converted into a digital signal by the A / D converter 17, and input to the microcomputer 18 constituting the calculating means 9. The microcomputer 18
The voltage value at the time of zero adjustment, the past weight value, and the like are stored in the memory 19. Further, the microcomputer 18 measures the output when the four pressure sensors 28 lower the toilet seat 3 as necessary, and stores this value as the offset value Cb. The offset value Cb is the magnitude of the voltage output by the pressure sensor 27 when there is no load, and the weight can be accurately measured by reducing this Cb during weight measurement. The microcomputer 18 stores the inclination k shown in FIG.
9 is stored. In the present embodiment, the microcomputer 18 calculates the weight from the voltage signal received from the pressure sensor 27 based on the weight conversion formula shown in (Equation 6) using the slopes k and Cb.

Weight value W = k · (V−Cb) (where V indicates a voltage value) (Equation 6) The arithmetic expression shown in (Equation 6) is for the case where one pressure sensor 27 is provided. The case of four is shown in (Equation 7).

Weight value W = k1 · (V1-Cb1) +... K2 · (V2-Cb2) +... Kn · (Vn−Cbn) (n = 4) (Equation 7) In this embodiment, when the toilet lid 2 is raised with the power on, the zero point adjustment is performed in this state.

The operation of this embodiment will be described below. When the user turns on the toilet lid 2 and lowers the toilet seat 3 while the power is on, the user sits on the toilet seat 3 as shown in FIG. Is done. That is, the four pressure sensors 27 housed in the toilet seat 3 detect a load corresponding to the weight of the user and transmit the load to the calculating means 8. At this time, the user raises both feet so that the entire weight rests on the toilet seat 3. The microcomputer 18 monitors the load value every several hundred ms, and starts the measurement only when a load equal to or more than a predetermined value is applied. In this measurement, the signal of the pressure sensor 27 is converted into a weight value using the above (Equation 7). The slope k at this time is set in the memory 19 at the time of adjustment, and the offset value Cb
Is stored in the memory 6c as a voltage value immediately after the toilet seat 3 is lowered before the load is applied after the power is turned on. The microcomputer 18 calculates the load value every several hundred ms as described above, and calculates the average value and the variation when this measurement reaches a predetermined number of times. Judgment is made and the average value at this time is displayed on the display means 5 as a weight value. In the present embodiment, the body weight is measured three times every 100 ms, and if the variation at this time is within 200 g, it is regarded as stable. The accuracy of one strain gauge constituting the pressure sensor 27 used in the present embodiment is 2.5 g / mV as a value after signal amplification. The body fat calculating means 8 calculates the body fat value by using the weight value and displays it on the display means 5.

As described above, according to this embodiment, the body weight can be automatically measured on the spot, and therefore, an accurate body fat value can be obtained.

(Embodiment 5) Next, a fifth embodiment of the present invention will be described. FIG. 11 is an external view showing the configuration of the operation means 4 used in this embodiment. In this embodiment, a menstruation start date input key 30 for inputting a menstruation start date is provided. Generally, a woman's basal body temperature is low during one cycle (from 28 days to 32 days) from the start of menstruation to the next menstruation.
It depicts two phases during the high temperature period. The difference in body temperature between the low temperature period and the high temperature period is about 0.4 ° C. The transition from the low-temperature period to the high-temperature period corresponds to the time of ovulation, and the metabolism becomes active, so that fat is easily burned and is an optimal period for dieting. Conversely, it is said that during the high temperature period, metabolism deteriorates, fats are difficult to burn, and the effect of dieting is difficult to achieve. In this embodiment, every time the organizing start is confirmed, the microcomputer 18 calculates the ovulation time, that is, the optimal period for dieting by pressing the organizing start date input key 30, and displays the diet mark 3 on the display means 5.
1 is displayed. This optimal time is calculated by adding the average menstrual cycle of the past three months to the latest menstrual start date, subtracting 12 and considering it as the ovulation time, and taking the period from that day to one week before as the optimal time. It is.

It should be noted that if the user performs a diet for a period other than the above-mentioned optimal period, the user may harm the health. Therefore, it is better for the user to perform the diet at a time suitable for the diet.
