Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to surface treatment of a vaporizing chamber of a steam iron, and particularly to improving vaporizing efficiency.

Generally, it is desirable for a steam iron to have a quick vaporization time after dropping water into the vaporizing chamber and a large vapor sealing ability. However, the water falling on the surface K11i of the vaporization chamber becomes spherical with a large contact angle and is gradually vaporized, so the vaporization time is long.
It has a low air-sealing ability, making it unsuitable for professional irons that require generating a large amount of steam in a short period of time. For this reason, we attempted to improve wettability in areas where water would come into contact with water over a wide range by applying epoxy resin or modified silicone resin paint to the surface of the vaporization chamber, but this was not necessary. Sufficient wettability was not obtained, and the contact angle 0) became large as shown in the abandoned line in Figure 2.

The present invention has been made in view of the above points, and will be explained below based on the drawings. fl+ is a sheathed electric heater (21
It is made of aluminum alloy with an additional vaporization chamber (31 and # vaporization chamber) on the top and a recessed chamber (4). 1 Part of the inner wall of the vaporization chamber (3) An enamel skin containing heat-resistant silicone F!FI paint as the main component and at least 10 to 30 x 1 of manganese dioxide as a binder and 2 to 3 x of crushed stone powder, oxidized!gnesicum, and aluminum oxide is formed. . +fi

The installation is done using a nine-drop shaft, a mounting screw and a mounting bracket that fixes the 0l-Fi tank (-) to the pace lid (6).

Next K[! To explain the method for forming the enamel (i), first, the inner wall surface of the vaporizing chamber (1 m) was degreased, and the above-mentioned heat-resistant silicone resin paint was used as the main component, and man dioxide,
After drying, an enamel containing silica powder, magnesium oxide and aluminum oxide is applied to form a film.
Fire at a high temperature of 00°C. Therefore, a film containing minute pores is formed on the inner bottom wall of the vaporization chamber 11).

Then, the drip shaft 04 is raised, and the hot water in the tank (6) is dripped onto the inner bottom wall of the vaporization chamber (11) through the nozzle part (1), improving the wettability and greatly increasing the vaporization ability. In the present invention #4, the enamel was provided on the inner bottom of the vaporization chamber, but it is clear that the vaporization ability would be further improved if the enamel was provided on the entire inner wall surface.

As described above, the present invention allows the vaporization chamber K11iTF-
In a device that generates steam by vaporizing water, a part or all of the inner wall of the vaporizing chamber is degreased, and a heat-resistant silicone resin paint is applied to the surface thereof, containing at least manganese dioxide and silica powder. Because it is made by applying enamel and drying it to form a film with pores,
Water dripping into the vaporization chamber from inside the tank has a contact angle of approximately 0 degrees due to the enamel film made of the above-mentioned material, and is instantly vaporized. The aforementioned enamel also provides corrosion protection for the inner walls of the vaporization chamber.
