PURPOSE:To form silent and comfortable electric stove by employing an alloy spring, provided with all direction shape memory, as the power of oscillating motion. CONSTITUTION:A leg 9 is provided with a slit 12, in which a protuberance 11 at the lower part of a main body moves, and the oscillating angle of the stove is determined by the slit 12. Another protuberance of the leg 9 and the protuberance 11 are connected by the alloy spring 15 having all direction shape memory. The lower part 8 of the main body is made of an insulating material. A thermostat 14, being put OFF at high temperature side and put ON at a low temperature side, is connected to the alloy spring 15 and an electric source and is equipped adjacent to the alloy spring 15 so as to receive Joule heat generated in the alloy spring 15. The protuberance 11 at the lower part 8 of main body is slid by the expansion and contraction of the alloy spring 15 to drive the oscillating motion of the main body 6 about a supporting pillar 10 while a motor or the like is not driven in this case, therefore, sound will never be generated and the silent and comfortable electric stove may be obtained. |
