A method of producing a thin film heating element is provided which can be used in manufacturing a transparent thin film heating element of desired shape with an increased heat emission property and an excellent durability.
On the contrary of known household appliances, the driving motor (2) is thus more strongly cooled when its heat emission increases and is less strongly cooled when its heat emission abates.
This makes the source cooled by its own heat emission.
Therefore, a considerably improved heat emission can be reached.
The present invention relates to a hairdryer, and the invention aims to maintain balanced heat emission by disposing, in conical form, a heat-emitting body employing a ceramic heater.
According to the inventive method, a vaporous phase of the substance condenses, emitting heat to the liquid phase of the substance, which is then partially or fully evaporated.
