Abstract

PURPOSE:To make a controller of an electric foot warmer compact by providing a plurality of electric circuits composed of specific electrical instruments and connecting a series circuit of a variable resistor and a capacitor and a semiconductor element in parallel. CONSTITUTION:A heater unit consists of a heater 5 connected to an alternating power source 29, a series circuit of a semiconductor control element 6 and a gate circuit 12 composed of a capacitor C and a switching element 15. The element 15 is connected between a control electrode of the element 6 and the capacitor C. A remote controller is provided with a variable resistor 25 connected to the capacitor C in series. The series circuit of the variable resistor 25 and the capacitor C is connected to the element 6 in parallel to form a circuit. The variable resistor 25 is thus made compact, since the charging/ discharging current from the gate circuit 12 are reduced and rated in low. The remote controller installing the variable resistor 25 is therefore made compact.

I:I) Prior art] Many devices have been published in which the amount of heat generated by a heater unit attached to the cod body can be varied using a remote controller. So warm! A rectifier with control pole (4
8 conduction, non-conduction Kr! Since the AC power supply voltage is constantly applied regardless of JA, the series circuit repeatedly charges and discharges continuously, causing a large current (discharge current) to flow through the temperature regulator (variable resistor), causing the temperature regulator to burn out. There was danger. Also,
If a temperature regulator with a large allowable current is used to prevent burnout, the temperature regulator becomes large and the remote controller is thick, making it difficult to use. In addition, in this prior art, many circuit components such as the aforementioned temperature regulator, adjustment circuit, ignition circuit, and rectifier with control poles are installed in the remote controller, so the outer diameter of the controller is large. Since the remote controller, which is frequently operated, is equipped with the above-mentioned electrical parts that are susceptible to shocks, there is a drawback that failures such as connection failures may occur, resulting in decreased performance and malfunctions.
