Thus, the knob can be held by the knob and pressed Rotate, so that the flow control of the gas is controlled by the #°°°, and the ignition device ignites the gas at the mouth of the furnace, and the gas flow can be adjusted through the knob on the control rod to control the furnace fire! Provide people, x, cooking food. However, the conventional gas flow controller can only control the switch and size of the fire by manual means, and it is not convenient in operation. When the gas furnace is not normally extinguished, it is easy to cause accidents due to the gas being not closed. For the shortcomings of the aforementioned traditional gas furnaces, some people nowadays have designed a variety of fire control devices with control functions, but the fire control devices are designed only when the fire is not normally extinguished, so that the gas flow controller turns off the gas' In order to ensure the safety of the use of the gas furnace, but the size of the furnace fire control! J, it fails to provide a good control mechanism. For this reason, for food that has to be stewed for a long time, it will be heated to a boil after a large fire or medium heat, and then it will be a small 4 ^98781 ' The operation mode of the multi-stage heating mode such as time heating is manually controlled by itself, so an automatic control mechanism cannot be provided. SUMMARY OF THE INVENTION Safety Control and Safety The main object of the present invention is to provide a fire control device for a gas furnace, which is designed to provide a fire safety control device having a good furnace size controllability.
