Fire warning method utilizing temperature sensor in gas range

摘要

PURPOSE: A fire warning method is provided to prevent damage to human life and property due to a fire by automatically operating fire extinguishing equipment installed in house while sending a text message to a customer or a fire related organization. CONSTITUTION: A controller resets a surrounded fire confirming timer and initializes a temperature value of temperature sensors(S1). The surrounded fire confirming timer is operated(S2). Whether each burner is in the use or not is determined(S3). Whether present temperature of the corresponding burner is higher than surrounded fire determination reference temperature or not is determined when a specific burner is not used(S4). Whether surrounded temperature of the corresponding burner is higher than initial temperature which is previously memorized or not is determined when the present temperature of the corresponding burner is higher than the surrounded fire determination reference temperature(S5). A surrounded fire confirming timer determines predetermined time-out when the surrounded temperature of the corresponding burner is higher than the initial temperature(S6). The controller outputs alarm sounds when surrounded temperature of the specific burner maintains the state which is higher than the initial temperature until the predetermined time passes(S7).
