Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric iron used for smoothing out wrinkles in clothing and sheet-like objects, and for shaping.

[Conventional technology]

Electric irons that are currently widely used have a nichrome wire placed on top of a metal iron such as iron or aluminum through an insulator such as mica or asbestos, and the heat produced by passing electricity through the nichrome wire can be used to iron the iron. It is designed to heat the parts.

[Problems with conventional technology]

However, in the electric iron mentioned above, the nichrome wire generates heat slowly, and the iron part has a relatively large heat capacity, so you have to wait about 5 minutes for the iron to reach the specified temperature after turning on the iron before use. Not only could the iron not be ironed immediately, but the heat would not cool down for a long time after use, making it impossible to move or store it. Also, because of its heavy weight, it was not easy to carry it when traveling overseas.

Furthermore, the surface of the iron part that comes into direct contact with the fabric of clothing is susceptible to rust, scratches, and glue, which requires constant maintenance to keep it in a clean state.

[Means to solve problems]

In order to eliminate the drawbacks of conventional irons as mentioned above,
The ironing section was constructed with a ceramic heater having a heating resistor built into a ceramic body.

[Effect]

Since the iron part itself is a ceramic heater, the temperature rises immediately and the iron is ready for use.

〔Example〕

As shown in FIG. 1, which is an overall perspective view of an electric iron according to an embodiment of the present invention, a handle portion 3 having a cord 2 is fixed to an iron portion 1 to constitute an electric iron. As shown in the three-dimensional exploded view in FIG. 2, this electric iron has an ironing part 1.
is made of a ceramic body such as alumina or silicon nitride, and a heating resistor 1a formed of a heating pattern formed by printing using a conductive paste such as tungsten is integrally embedded in this ceramic body.

Incidentally, "integrally embedded" means that the ceramic body and the heating resistor 1a embedded therein are integrated by simultaneous firing. For example, a heating pattern is formed on an unfired ceramic molded body using a printing method using tungsten paste, another ceramic molded body is closely attached to cover this heating pattern, and the whole is simultaneously fired and integrated. Bye. At this time, a bonding layer containing a mixture of both components is generated at the boundary between the heat generating pattern made of tungsten and the ceramic body, and the two are firmly bonded. Therefore, not only the heating speed when energized is fast and the thermal efficiency is high, but also the risk of wire breakage can be reduced.

Further, both ends of the heating resistor 1a are led out by external leads 1b. On the other hand, the handle part 3 is provided with a connector 2a at the lower part through which the cord 2 for energization is inserted, and when the external lead 1b is inserted, the heating resistor 1a is energized, and the iron part 1 The handle portion 3 is detachable.

It is convenient to provide the handle portion 3 with a mechanism for adjusting the current in order to control and set the amount of heat generated by the heating resistor 1a.

[Effect of idea]

According to the present invention, since the iron part itself is composed of a ceramic heater, the iron part can be used within several tens of seconds after being energized, so the temperature rises quickly and the heat efficiency is good. Further, the surface of the ironing part that comes into contact with the fabric does not get rusted or damaged, and moreover, it is possible to always perform good ironing without getting dirty.

Furthermore, since the electric iron cools quickly after use, it is easy to clean up after use, and since the handle part and the iron part can be separated, it is compact, and the iron part is also lightweight, making it possible to provide an electric iron that is easy to carry.
