Abstract

PURPOSE: To reduce the cost with a simplified construction by arranging a member made of a constitution memory alloy with such a shape as to turn back to the original state due to a temperature change, a display body for indicating a change in the shape of thereof and a heat source for heating the member.
CONSTITUTION: A coil spring 5 made of a constitution memory alloy is so thermally treated to change to a state as indicated by the broken line from that as indicated by the solid line in the shape by memory when the temperature is raised to a certain level from the normal level. An indicating member 6 is painted red, for example, and connected to the coil spring 5. This apparatus is provided with a spiral sheathed heater. After the end of cooking, the heater 1 is switched off. Then, immediately a pan is taken off the heater, the spring shifts from the state as indicated by the solid line to the broken line and the indicating member pops up on the surface of the heater 1 to indicate a hot condition. This provides an inexpensive device with a simple construction.
