Description

TECHNICAL FIELD [0001] The present invention relates to a steam iron manufacturing method and steam iron,

The present invention relates to a steam iron manufacturing method and a steam iron, and more particularly, to a steam iron manufacturing method and a steam iron, and more particularly, to a steam iron manufacturing method and a steam iron, The present invention relates to a steam iron having a large area and capable of simultaneously forming a steam chamber inside a steam plate body while forming a steam plate body integrally by die casting, and a steam iron produced thereby.

Steam heated by the heater is supplied to the internal steam chamber of the steam plate body constituting the body of the steam iron, and the steam (steam) The steam is discharged to the bottom surface of the steam plate body through the steam hole communicated from the steam chamber inside the steam plate body to the bottom surface, thereby forming a steam iron. A steam iron having a water supply tank for always supplying water required for steam ironing and a heater for heating the water to supply water by steam is used. In the case of a steam iron performing ironing by this water supply at all times, A water pump for pumping the water is provided to heat the water by the heating heater to generate steam, and the steam is discharged under the ironing plate.

At this time, it is necessary to form a steam chamber to be a line for supplying steam inside the steam plate body. In the conventional steam iron, since the steam chamber line inside the steam plate body is formed to be narrow, There is a problem that the steam can not be supplied properly. There is a problem that the steam supply is not properly performed due to the repeated phenomenon that the steam is discharged through the steam hole at the bottom of the steam valve body.

In addition, since the steam supply port, the condensate discharge port, and the steam supply connection port are formed by drilling the steam plate body in the conventional manner, the number of workpieces increases when the steam plate body is formed, There is a problem that the cost is increased.

On the other hand, in the conventional steam iron, the steam plate body is formed by welding a stainless steel plate to the lower plate. When the stainless steel plate is welded to the lower plate, steam pressure or the like causes the welded portion of the stainless steel plate to burst , There is a problem that it can not be used properly as a steam iron, and in the case of a product obtained by welding stainless steel plate and bottom plate, there is also a problem that the work flow increases and cost increases.

The present invention having the above-described structure is characterized in that the first steam chamber 12 and the second steam chamber 14 are formed in the steam plate body 10 by using the first foundry sand 112 and the second foundry sand 114 The effects of the present invention are as follows.

1. Molding the steam plate body 10 in a state where the first casting mold 112 and the second molding sand 114 are accommodated in the cavity of the inside of the molding die of the steam plate body 10, After the first steam chamber 12 and the second steam chamber 14 are formed in the steam plate body 10, the first foundry sand 112 and the second foundry sand 114 are removed, And the productivity is improved.

2. The steam chamber in which the first steam chamber 12 and the second steam chamber 14 are formed as a line for supplying steam to the inside of the steam plate body 10, Therefore, there is an effect of solving the problem of a large load at the time of supplying steam and solving the problem that the steam is not supplied properly. It is possible to completely solve the problem that the steam supply is not properly performed by repeating the phenomenon that the steam flows out through the steam hole 16 on the bottom surface of the steam plate body 10 and is broken.

3.
