Title:
AUTOMATIC FIRE EXTINGUISHER FOR COOKER
Document Type and Number:
Japanese Patent JPH0634138
Kind Code:
A
Abstract:

PURPOSE: To automatically set a fire extinguishing temperature and to eliminate missetting of a high fire extinguishing temperature even if a pot of heated oil is placed.

CONSTITUTION: Temperature gradient operating means 2 calculates a temperature gradient (a temperature rising speed per unit time) based on a detected temperature of a temperature sensor 35 for detecting a temperature of a cooking implement. Fire extinguishing temperature setting means 4 sets at least two stages of fire extinguishing temperatures responsive to the same temperature gradient when the operated gradient is less than a highest temperature rising speed stored in highest temperature gradient memory means 3 and sets a low fire extinguishing temperature when the gradient is the highest temperature rising speed or more. Heat stopping means 1 stops an operation of heating means 10 if the detected temperature of the sensor 35 exceeds the set fire extinguishing temperature.
