1. Occurrence Situation of Accident

A user used a hair drier which has been used for 7 months, for about 5 minutes, turned off the body switch without pulled out the power plug from an outlet, and put it on a netted basket in a wagon. 30 minutes later, smelling something burnt, the user looked at the hair drier to find it thermally deformed and so pulled out the power plug.

2. Origin of Accident

The result of a test for this accident performed by the National Institute of Technology and Evaluation showed that an air blowing fan circuit is stopped due to the loose connection with the power switch (slide type) turned on and the user thought that the switch was turned off and left it as it was, however, only a heater side circuit was energized to cause thermal deformation. In this product, both of an excessive temperature rise prevention device and a temperature fuse were installed near the hot air blowout port so that, when the blowout port of the hair drier was placed with the bottom up and if the heater only was energized and heated, the temperature fuse was not welded and it may cause smoking or ignition.

3. Measures

From the viewpoint of prevention of the accident recurrence, the design of the circuit was changed so as to prevent the heater side circuit from being energized, even if the air blow fan is stopped.
