Electric steam iron is to reduce the effort of spraying water by a separate injector by the worker who performs ironing, the steam generated from the inside or outside of the iron is sprayed on clothes, sewing, etc. It is widely used for ironing work to flatten wrinkled parts such as clothes and sewing by iron base plate heated by.

 Electric steam iron used in sewing factories or laundry where a large amount of steam is required generates a lot of steam in the boiler and supplies the generated steam to each iron mobilized in the ironing operation, and the worker uses the steam for ironing. In this case, since a large amount of steam is generated by using a boiler, it is possible to supply enough steam to each iron continuously, but it is necessary to always generate a larger amount of steam than the steam required for each iron, The boiler must be operated at all times in order to prepare a case, the disadvantage is that the boiler operating cost is high. In addition, the cost of the steam supply equipment for supplying the steam generated from the boiler to each iron and the steam loss cost are large, and sometimes the steam is liquefied and the water is sprayed.

In order to overcome the disadvantage that the cost of using the boiler increases, the electric steam iron is provided with a steam generating chamber in the form of a water tank to fill the iron body and heat the water to generate steam, It is pointed out that the steam generated in the water tank is liable to be liquefied into liquid droplets until it is ejected from the iron, and thus it is difficult to spray steam in a sufficiently vaporized state, and it is difficult to continuously provide steam due to insufficient amount of steam generated. .

In addition, in order to overcome the disadvantage that the cost of using the boiler is increased, the tank having a water tank filled with water to the outside of the iron body and the water supplied from the water tank to heat the water to generate a steam generating chamber The electric steam iron provided inside is supplied, but it is also difficult to prevent water from being injected due to liquefaction until the steam generated in the steam generating chamber is injected, and the amount of steam is not enough to continuously steam Problems that are difficult to provide are pointed out. In addition, since the water supplied to the tank is in a low temperature state, it takes time until it is warmed up from the steam generating chamber to the steam generating temperature, and thus, the disadvantage of generating a time difference as much as the warming time in the steam generation amount is pointed out.

Applicable to both heating methods.

In this case, in order to insulate the heater wire and the heating plate, mica, plastic, or a liquid adhesive, which withstands high temperature, may be used, but in the present invention, a technique of insulating using a liquid adhesive may be employed, which is the subject of the present invention. Because of the distance there is a risk of confusing the core of the present invention will be omitted.

In the accompanying drawings of the present invention, for convenience of description, it is illustrated that a direct heating method in which a heater wire is embedded and heated is described. However, the heating method describes only the parts necessary for describing the steam generating method of the present invention, and the detailed description thereof It will be omitted.
