Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a steam iron, and more particularly to a steam iron that utilizes heat and steam produced by a chemical reaction between quicklime and water.

[Conventional technology]

It has been well known that when quicklime and water are combined, heat and steam of nearly 200°C are generated, but a steam iron that utilizes this heat and steam has not yet existed. Conventional steam irons used electric heat.

[Problem that the invention seeks to solve]

Conventional electric steam irons have complicated structures and are expensive to manufacture. In addition, it is bulky, requires an AC power source, and is inconvenient to carry. Furthermore, since we used an AC power source and water at the bottom of the house, we had to take sufficient safety measures to prevent electric shock. Furthermore, there was a risk of a fire due to overheating due to forgetting to turn off the switch.

According to this invention, heat and steam can be generated simply by combining quicklime and water inside the steam iron body, so the structure is simple, manufacturing costs are low, and the size is compact and portable. It is possible to provide a steam iron that is convenient and free from electric shock and fire.

[Means for solving problems]

The steam iron of this invention has the following configuration.

(b) Must have a main body.

(b) The main body must have a storage chamber inside.

(c) The storage chamber of the main unit shall be equipped with a heat generating means for causing a chemical reaction between quicklime and water and transmitting the heat generated by this reaction to the bottom surface having a flat surface.

(d) A discharge hole is formed on the top surface of the main body to discharge the water vapor generated by the reaction, and this discharge hole is provided with a filter that allows only water vapor to pass through.

(E) A guide path is provided at the front of the main body to blow out the water vapor discharged from the discharge hole forward of the bottom of the main body.

[Effect]

When quicklime and water are combined inside the main body, heat and steam are generated. This heat is transferred to the bottom surface of the main body, which has a flat surface. On the other hand, water vapor is discharged from a discharge hole provided at the top of the main body, and guided to the front of the bottom surface of the main body by a guide path. In this way, steam is first sprayed from the guide path onto the piece of cloth to be ironed, and immediately after that, the heated flat surface of the bottom of the main body passes through it, smoothing out the wrinkles in the piece of cloth.

〔Example〕

The main body 1 is made of metal or ceramics and has a box shape. As will be described later, the rear portion 1a is provided so as to be openable and closable. Bottom 1
b is formed into a flat surface.

Quicklime and water can be accommodated inside the main body 1, allowing a chemical reaction to take place. Heat generated inside the main body 1 due to this chemical reaction is transferred to the bottom surface 1b. The upper surface 1c of the front part of the main body 1 is provided with a discharge hole 3 for discharging water vapor generated by the chemical reaction. Two to four small-diameter exhaust holes are installed to prevent water vapor from being exhausted all at once.
It is a good idea to provide at least one. A filter 4 made of high-density fiber such as the product name "Gore-Tex" (Renown Co., Ltd.) or the product name "Nomex" (Toray Co., Ltd.) is attached to the discharge hole 3, so that quicklime and water are discharged from the discharge hole 3. It is designed to prevent this from happening.

A casing 5 that has substantially the same shape as the main body 1 and covers the main body 1 is attached on the main body 1.
The main body 1 and the casing 5 are tightly fitted at the front and both sides to prevent water vapor from leaking. Main body top surface 1c and casing top surface 5
A space 6 is formed between the space 6 and a. In the center of this space 6, a wall 7 is provided integrally with the casing 5 to partition this space 6 into a front part 6a and a rear part 6b. The front part 6
It is arranged so that they gather only in a.

The casing 5 is made of plastic or ceramic, and inside its front wall 5b,
A guide path 8 is formed to guide water vapor discharged from the discharge hole 3 into the front portion 6a to the front of the bottom surface 1b of the main body 1.

The lower surface of the casing 5 is open, and the rear wall 5c is rotatably attached to the upper rear end of the casing 5. The rear part 1a of the main body 1 is integrally provided inside the lower part of the rear wall 5c. The rear portion 1a is fitted into the rear opening 1d of the main body 1 to prevent liquid or gas within the main body 1 from flowing out.

Note that by disposing the polymer absorber 9 above the discharge hole 3, it is possible to prevent the water vapor discharged from the discharge hole 3 from turning into water droplets and flowing out from the guide path 8.

Also, as shown in Figure 2, prepare a Japanese paper bag containing quicklime and a rubber or polyethylene bag containing water, and stack them inside the main body 1 with the water-filled bag facing upward. A means for bursting the bag filled with water may be provided in the main body 1.

That is, a needle body having a push button portion at its upper end is disposed with its tip facing into the main body 1 through the casing upper surface 5a, the space front portion 6a, and the main body upper surface 1a, and this needle body is connected to the casing upper surface 5a. A bursting means 10 may be provided which is always urged upward by a spring 11 interposed between the upper surface 1a of the main body and the upper surface 1a of the main body.

When a Japanese paper bag filled with quicklime is placed inside the main body 1 and an appropriate amount of water is injected, heat and steam are generated by a chemical reaction. The heat is transferred to the bottom surface 1c, and the water vapor flows out to the front part 6a of the space 6 through the exhaust hole 3, and passes through the guide path 8 to the bottom surface 1 of the main body.
It is ejected in front of c. Steam is first sprayed from the guide path 8 onto the piece of cloth to be ironed, and then the heated bottom surface 1c passes through it.

According to the present invention, since the structure is simple, it is easy to operate, the manufacturing cost is low, and it can be made compactly and does not require an AC power source, so it is convenient to carry. Moreover, there is no need to worry about electric shock or fire.

〔effect〕

The steam iron of this invention combines quicklime and water inside the steam iron body and utilizes the heat and steam generated thereby, and has an extremely simple structure and low manufacturing cost. It can also be made compactly,
It is convenient to carry as it does not require AC power. Moreover, since it does not use AC power, there is no risk of electric shock, and there is no need to worry about forgetting to turn it off, so there is no risk of fire.
