PURPOSE:To disolve a problem of wire capacity in case of two space heaters used in parallel by imparting the heaters with an energy saving control function such that power supply is interrupted if a room temperature exceeds a predetermined value and started if the room temperature drops down below the predetermined value, and also by providing a plug-socket permitting the power supply when a power supply circuit of a heater of the space heater such as a carpet or the like. CONSTITUTION:In a room temperature sensing circuit 6, a sensor 7 for detecting the room temperature is provided, in which a relay 10 to turn ON and OFF the power supply at a predetermined temperature. A power supply circuit part 5 is adapted to control a relay 11 turning ON and OFF a heater 8 and the plug-socket 9. With this construction, by supplying power alternately to a carpet body 12 and the plug-socket 15, a power source of an electric stove or the like can be taken from the same plug-socket in view of current, and at the same time, the room temperature can be increased. Regarding the rising of the room temperature, if the detected value of the room temperature sensing circuit 6 reaches the predetermined value, the power supply to the heater 8 and plug-socket 9 is interrupted. After that, if the room temperature drops down, a room temperature control to place the heater 8 and plug-socket 9 in the power supplied state is effected, thereby rendering the both functions of raising the room temperature and saving energy to be effective at the same time. |
