[Table] FIG. 4 is a time chart of the output 49 signal of 23, the R terminal input signal, the output Q signal, and the S terminal input signal. State A is the state when the human body is placed, and 49 signals are present.
High, R terminal input signal Low, Q signal High, and S terminal input signal High. The body temperature is set by the user. In state B, the human body is no longer placed, and the signal 49 becomes low, so it is R.
The terminal input signal becomes High, and the S terminal input signal becomes
Since it remains High, the timer starts from Table 1 and the frequency divider starts counting. Keep the main body temperature low during the counting operation. After that, when the time-up occurs, the Q signal goes low, and the shorted S terminal input signal also goes low.
becomes Low. This state is a state in which the heater is not energized and is called the C state. After that, when the human body is placed again, the signal of 49 is High.
Therefore, the R terminal input signal becomes Low, the Q signal becomes High from Table 1 (which clears the frequency divider), and the S terminal input signal also becomes High. (Status A) After that, when no human body is placed, the signal 49 goes low.
Then, the R terminal input signal becomes High, so the timer starts and the frequency divider starts counting.
(State B) After that, when the human body placement state occurs before time-up, the signal 49 becomes High and the R terminal input signal becomes Low, so as shown in Table 1, the oscillator is stopped and the frequency divider is cleared. Q signal and S terminal input signal are
Remains High. (A state) After that, each signal is similarly generated based on the 49 output signals.
Change. Therefore, states A, B, and C can be determined from the output signal of 49 and the output Q signal of timer circuit 46. A is 49 signal High, Q signal High, B is 49
Signal Low, Q signal High, C is 49 signal Low,
The Q signal is low. Based on this, logic circuit 5
Configure 0. If the 49 signal is High and the Q signal is High (A state), only the output of the AND circuit 43 becomes High, so the transistor 37 turns on and the temperature setting voltage of 32
V 32 is a voltage obtained by dividing the DC voltage V 27 of 27 by resistors 15 and 16 and variable resistor 19. If the 49 signal is low and the Q signal is high (B state), only the output of the AND circuit 44 becomes high, so the transistor 38 turns on and V 32 connects V 27 to resistor 3.
The voltage will be divided by 4 and 35. (V 32 in B state
(Determine the resistance so that it is sufficiently smaller than V 32 in the A state) If the 49 signal is low and the Q signal is low (C state), only the output of the AND circuit 45 becomes High, so the transistor 21 turns on. . By the way, during the negative cycle of the AC power supply V 2 in No. 2, the transistor 6 turns on, and the current flows from the DC power supply V 21 through the parallel circuit of the resistor 14 and the capacitor 20 (the capacitor 20 is charged) to the transistor 6.
The current flows through the path of the temperature sensor 4 and the resistor 3. 2 is in a positive cycle, the charge stored in the capacitor 20 is discharged via the resistor 14. By the way, the temperature signal voltage V 31 of 31 is changed by the temperature sensor 4. As the temperature of the main body increases, the impedance of the capacitor 4 decreases, the current increases, and the charge charged in the capacitor 20 increases, so the voltage of V31 decreases. When the main body temperature decreases, the impedance of capacitor 4 increases, the current decreases, and capacitor 2
Since less charge is charged to 0, the voltage at V 31 increases. Therefore, in states A and B, 31 temperature signal voltages
If the temperature setting voltage V 32 is V 31 ≧ 32, the signal of the output 33 of the comparator 24 becomes High, and the transistor 22 turns on, so the relay 25 turns on.
The heater 26 is energized. If V 31 <V 32 , the heater 26 is not energized. In state C, the transistor 21 is turned on, so the transistor 22 remains off regardless of the magnitude of the input voltage to the comparator 24, and the heater 26 is not energized. Effects of the Invention By providing a new control circuit as described above, the user can control the temperature of the main body according to his/her preference when the device is placed on a human body. When no human body is placed on the device, the main body is controlled at a low temperature, which saves energy, and the main body temperature can be set without depending on the user's settings, so there is no need for human intervention. In addition, the timer is started at the same time as the detection that no human body is placed, and when the timer expires (while the timer is running, the main unit is kept at a low temperature), the power to the heater is stopped, which prevents the user from forgetting to turn it off and also saves energy. Become. If a human body is detected while the timer is operating when no human body is placed, the timer is immediately cleared and the body temperature can be changed to the user's set temperature in a short time. This is because the main unit was left on standby at a low temperature. As described above, the user can always feel more comfortable than the main body.
