めになされたもので。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temperature control device for electric heating devices such as electric blankets, electric bed blankets, electric lap cushions, electric cushions, and electric carpets. As shown in FIG. 1, the temperature control device is constructed by connecting a signal P wire 6 to a heating wire 4 via a heat-sensitive layer 5, and connecting a heating resistor 10 connected between the signal wire 6 and a power source 1 in series with the heating wire 4. With the circuit configuration provided near the temperature fuse 9 connected to the heating wire 4., the above-mentioned heating wire 4. Heat sensitive layer 5. A heating element 3 consisting of a signal line 6
are arranged in a meandering pattern, and when this heating element 3 causes abnormal heating, the short circuit current flowing between the heating wire 4 of the heating element 3 and the signal 116 causes the heating resistor 10 to generate heat, causing a temperature drop.
It was designed to maintain safety by fusing Use 9 and cutting off power to 9 circuits. However, temperature fuse 9
When the heating element 30 melts, the heat-sensitive layer 5 between the heating wire 4 and the signal wire 6 is also melted, so the heating element 3 cannot be reused. ! This was done to eliminate the above drawbacks.

近傍に設置するものである。The structure of the embodiment is as shown in FIG. 2, and numerals 1 to 10 in FIG. 9 are common parts with the same numbered parts in FIG. 1, and the structure is the same, so the explanation will be omitted. In addition, a switching element 70 connected to the heating wire 4 and a trigger circuit 8 are connected to the trigger terminal.
is connected to the other switching element 014, which is not explained here because it has nothing to do with the effect, another resistance heating element 15, and a trigger circuit 17. 15 and other switching elements 14
are connected in series to the power supply 1, and the trigger terminal 16 of the other switching element 14 is connected to the cathode of the diode 11 and the resistor 12. The anode of the diode 11 is connected to the signal line 6, and the other heating resistor 15 is connected to the temperature fuse 9 together with the heating resistor 10. It is installed near the.

す。その結果。To explain the operation of this embodiment, in normal operation, the impedance between the heating wire 4 of the heating element 3 and the signal line 6 is large, so no current flows through the heating resistor 1o or the diode 11, and therefore the heating wire 4 The trigger circuit 8 works to maintain a constant temperature by squeezing the cyst through which the stain flow has flowed. On the other hand, due to some reason, the heating element 5
When abnormal overheating occurs and the temperature rises, the impedance of the heat-sensitive layer 5 decreases and a short circuit current begins to flow. The current flows to the heating resistor 10 and the diode 11. In this case, the short-circuit current is initially so small that no heat can be generated in the heating resistor 10. But diode 11
The current that flows through the gate current of the other switching element 14 is different from the gate current of the other switching element 14, and the trigger terminal 16 is energized. This gate current turns on the other switching element 14, which conducts with the AC power supply 1 and connects the other heating resistor 15. Flow the current of AC power supply 1. the result.

を未然に防止できる。The other heat generating resistor 15, which is connected to the heat generating resistor 10 at a minus point, generates heat, and the fuse 9 connected to the heat generating resistor 15 is heated to a temperature of P to quickly blow it out, thereby cutting off the current supply to the circuit. In this case, the heating wire 4 of the heating element 3 and the signal wire 6
Since the heat-sensitive layer 5 in between is not completely melted, it is only necessary to replace the temperature fuse 9, and the heating element 3 can be reused. If the switching element 14 does not operate due to some kind of failure, the heating resistor 10 generates heat and melts the temperature fuse 9 to cut off the circuit, thereby preventing accidents such as fire.

用による電気採暖具の、有効利用が計れるものである。According to Kiki M, the heating wire of one heating element and the switching element are connected in series, and the heating resistor is connected to the signal line.
Furthermore, another heating resistor and another switching element are connected in series to both ends of the power supply, and a signal line is connected to the trigger terminal of the other switching element via a trigger circuit, and the other heating resistor is connected to both ends of the power supply. Because it is installed near the temperature fuse, when a short-circuit current starts to flow between the heating wire of the heating element and the signal wire due to some abnormality, this current will drive this attached circuit and disconnect the other heating resistor. By quickly blowing out the temperature fuse, the heating element P can be protected and the heating element can be reused, allowing effective use of electric heating equipment by adopting this circuit.
