Technical Field
The present invention relates to a hot air blower, and more particularly, to a hot air apparatus in which neither an air flow passage nor a heating module contacts metal ions.
Background
There are several ways to heat indoor in winter, among which electric heating is a simple heating way with low equipment cost. Wherein, the heating can be directly heating and wind heating; the direct heating comprises infrared heating, commonly known as little sun, heating quartz tubes and then directionally radiating heat through reflecting surfaces, and further comprises an oil heater, wherein oil is heated to circulate in pipelines and can play a similar heating radiator effect. Wind-heat heating is similar to a fan, but is electrically heated in the path of the wind by various materials, most commonly heating wires. At present, materials used by common air heaters are not limited generally, various materials such as metal, plastic and the like are mostly adopted, and the air heaters cannot meet the requirement of heating equipment which is specially used and does not need to be in contact with metal ion components.
