せ主電流制御手段（１５ｒＯＮする。In FIG. 4 1, when a voltage from a commercial power source (161) is applied, a current flows through the heat sensitive layer (3) and is converted into a voltage by the temperature detecting means U.Next, a temperature comparator←J detects the temperature. Setter (compares the set voltage created by 1z and the temperature detection means voltage, and the temperature detection means voltage is lower than the set voltage. Temperature comparator 03) output is a HI multiplied signal.The HI multiplied signal is the main current control means drive circuit. The main current control means (15rON) is connected to the α current and generates all zero volt pulses.

理由よりＮ気力−ペットなどの大電流負荷の採暖具に１
線式の採用ができなかった。Up until now, I have tried to apply a one-wire wire to an electric carpet, but controlling the load heater with full waves means that the output of the temperature detection means differs when the heater is energized and when there is a power outage. Since the voltage is different (heater wire is high), it is not possible to extract a constant voltage from the temperature detection means regardless of a power outage when electricity is supplied to the heater.Therefore, the method is the same as the negative wire type blanket. I tried using half-wave control to extract the current flowing to the sensor during the negative half-cycle when the heater was out of power, but because the load was a large current, the balance between the positive and negative sides of the power supply became unbalanced, which adversely affected the power supply. . In addition, a large heat sink is required to dissipate the heat of the SCR, which is a half-wave control element, resulting in an increase in the size of the controller case. For the above reasons, N Ki-ryoku is suitable for heating devices with large current loads such as pets.
It was not possible to adopt the wire system.
それ故に本発明の目的は、一本化ワイヤーを用いて安定

採暖具用温度制御装置を提供することにある。Therefore, an object of the present invention is to provide a temperature control device for an electric heating device that uses a single wire to obtain a stable signal, forms a final safety circuit, and is inexpensive.
