That is, the positive (+) (-) AC power is directly applied to the heating wire of the heat-sensitive wire, and heat is generated. Especially, the AC power of the (-) component applied to the heating wire is a nylon positioned between the heating wire and the temperature detection wire constituting the thermal wire. Since the leakage is induced through the thermistor (Nylon Thermistor) to the temperature detection line (capacitive leakage current), the error of the temperature detection voltage increases and the temperature control becomes unstable.

To judge. If the current time point is the lowest point, as shown in FIG. 5, a temperature detection signal is output to the transistor Q2 to turn on the transistor Q2, and then detected by the sensor winding S2. The sensor voltage is input through the resistors R38 and R7 while the temperature setting voltage output from the second temperature setting unit 111 is received. At this time, the second temperature setting unit 111 forms a closed loop with the microcontroller 117 as shown in FIG. 2 as soon as the transistor Q2 is turned on to form the resistors R20 and R3 ( The temperature setting voltage determined by R22 is input to the microcontroller 117.

Then, the microcontroller 117 compares the sensor voltage with the temperature set voltage and counts a preset time, and then outputs a heat generation driving signal to the heat generating unit 119 as shown in FIG. 5.

If the current time point is the highest point, as shown in FIG. 5, an overheat detection signal is output to the transistor Q2 to turn on the transistor Q2, and then the sensor sensed by the sensor winding S2. It is judged whether it is higher than the preset temperature by receiving the voltage, and if it is low, it is determined to be in normal operation and then goes into a mode for outputting a temperature detection signal, and if it is high, it recognizes that the heating winding H2 is overheated. Power AC1 and AC2 supplied to the heating winding H2 are automatically shut off.

Since the method of detecting the heating temperature of the heating winding H1 is also the same as the method of detecting the temperature, a detailed description thereof will be omitted.

It is inverted again and input to the gate terminal of the thyristor (TH1) (TH2) to turn on the thyristor so that the power source (AC1) (AC2) is supplied to the heating winding (H1) (H2), the heating winding (H1) (H2) Fever.

Thereafter, the microcontroller 117 checks the voltage input from the zero potential detector 131 to determine whether the sinusoidal AC power source AC1 is a falling edge, determines whether it is the lowest point of the falling section, and then the left side. Then, it is determined whether the right heat transfer mat operates normally.

That is, when the current time point is the lowest point, the microcontroller 117 outputs a temperature detection signal to the transistor Q1 and turns on the transistor Q1 as shown in FIG. 5A. The sensor voltage sensed by the sensor winding S1 is input through the resistors R37 and R6 while the temperature setting voltage output from the first temperature setting unit 109 is received.

As described above, the microcontroller 117 checks the heat transfer temperatures of the left heat transfer mat and the right heat transfer mat with a time difference.

On the other hand, the microcontroller 117 checks the output signal of the zero potential detection unit 131 to determine whether it is the leading edge of the sinusoidal AC power source AC1, and determines whether the rising point is the highest point. If the current time point is the highest point, as shown in (a) of FIG. 5, an overheat detection signal is output to the transistors Q1 and Q2 and the transistors Q1 and Q2 are turned on. The sensor voltage sensed by the sensor windings S1 and S2 is input to determine whether the temperature is higher than the preset temperature. If the temperature is low, the sensor voltage is judged to be in normal operation. If it is high, it recognizes that the heating winding (H1) (H2) is overheated, so that the power (AC1) (AC2) supplied to the heating winding (H1) (H2) is automatically cut off.

Since the method of detecting the heating temperature of the heating windings H1 and H2 is also the same as the method of detecting the temperature, a detailed description thereof will be omitted.

(Electric field Detection mode )

As described above, the electric field detection unit 127 operates the left heat mat, and the plug is connected to the outlet so that the negative power terminal of the microcontroller 117 achieves a cold state, or hot (HOT).
