The purpose of this study is to investigate the cause of fire and to investigate the risk of general ignition of the small electric hot air fan using PTC thermistor, which is one kind of electric heater which is used for indoor heating in winter. The general characteristics of the PTC thermistor, which is a heating element in both normal operation and abnormal operation, is that the resistance increases as the temperature rises and the current is lowered while the temperature is lowered. The possibility of ignition due to overheating is low. However, conductive material such as moisture,When the bimetal surface, which is a heater and an overspeed prevention device, is contaminated, leakage current flows on the surface of the insulating material, and it is confirmed that sparks occur and lead to fire. In order to reduce the risk of ignition due to such contamination, it is required to design the product in consideration of the use environment, such as the use of a filter capable of minimizing the water and dust that may enter the electric hot air fan.
