Problems to be Solved by the Invention However, since the opening c is near the upper part of the burner of the gas range, there is a problem that the smoke or the like sucked in has a high temperature and is not suitable as cooling air for the motor 2. The casing of the motor 2 has an air hole for improving the cooling effect, and has a structure in which the cooling air directly touches the coil and the bearing. Therefore, if used repeatedly, oil, acid, etc. contained in smoke will adhere directly to the coil and bearing,
There are problems such as deterioration of mobility at low temperature and electric shock due to deterioration of insulation performance.
