Abstract

PURPOSE:To obtain a steam iron with a sufficient vaporization capacity even if steam is increased by providing a film, a mixture of polyphenyl sulfide resin and silica fine particles, on the inside of a vaporization chamber. CONSTITUTION:A vaporization chamber 1 wherein steam is generated, is provided on the top of a base 3 with a built-in sheathed-heater 2. A film 4, a mixture of polyphenyl sulfide and silica fine particles, is formed on the inside of the vaporization chamber 1, in order to improve vaporization efficiency. The film, the mixture of polyphenyl sulfide and silica fine particles, is applied and baked on the inside of the vaporization chamber. The silica fine particles are thus disclosed on the surface of the film and increase the surface area coming into contact with water. Furthermore, since the silica has a very highly hydrophilic property, it can instantaneously vaporize even a lot of water. The title iron is therefore made so that waterdrops are not spouted from a steam hole even if the steam is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention improves a vaporization chamber that generates steam,
This invention relates to a steam iron that has an improved ability to vaporize water dripping from a water storage tank.

Conventional Technology Conventionally, in steam irons, silicone resin, polyphenyl sulfide resin, etc. were applied to the surface of the vaporizing chamber of the base made of aluminum material to increase the vaporizing ability. If the aluminum fabric is used alone, the water droplets will form beads and will not instantly vaporize, so a hydrophilic film is coated on the aluminum fabric to speed up water evaporation.

Problems to be Solved by the Invention However, the coatings made of these materials do not have sufficient ability to vaporize dripping water, and when a large amount of dripping water is vaporized and steam is increased using a larger amount of steam than usual, Sometimes dripping water that cannot be vaporized comes out from the steam outlet.

Therefore, an object of the present invention is to form a film on the inner bottom surface of the vaporizing chamber that is heat resistant and has an excellent vaporizing ability, and to obtain a steam iron that has sufficient vaporizing ability even when increasing the amount of steam.

Means for Solving the Problems In order to achieve the above objects, the present invention uses polyphenyl sulfide (p, p,
s) mixed with silica fine particles.

By mixing silica particles with polyphenyl sulfide (p, p, s), the surface area of the vaporization film is increased, and the hydrophilicity of the glue (Sin2) particles acts to greatly enhance the vaporization ability. I can do it.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, a vaporization chamber 1 for generating steam is provided on the upper surface of a base 3 containing a sheathed heater 2 therein. A coating 4 made of polyphenyl sulfide mixed with fine silica particles is formed on the inner surface of the vaporization chamber 1 in order to increase vaporization efficiency. That is, like fine silica particles, polyphenyl sulfide is also dispersed in water using a surfactant, coated on the inner surface of the vaporization chamber, and then baked to form the film 4. The film thickness of film 4 is 10~
If it is too thin, the thermal buffering effect of the film 4 will be weakened and water droplets will be easily repelled.

Moreover, if it is too thick, the film 4 will peel off due to heat.

A drip nozzle 6 is provided in the water storage tank 6 to guide water to the vaporization chamber 1 that generates steam, and a steam button 7 and an opening/closing rod 8 are installed.
The dripping of water is controlled by the operation of

Reference numeral 9 denotes a steam increase button, which, when operated in the vertical direction, sends a large amount of water into the vaporizing chamber 1 through the horizontal nozzle 10 through a pump action, thereby generating a large amount of steam.

Steam is generated with the above configuration, but if the vaporization ability of the film 4 is not good, press the button 9 to increase the amount of steam.
If a large amount of water is sent into the vaporization chamber using the steamer, some of the water droplets will fly out from the steam hole 11 without being vaporized, making it inconvenient to use. However, if you continue to operate the increasing steam button, water will leak from the steam hole due to the lack of heat in the base itself, but apart from this phenomenon, the initial vaporization ability when performing the increasing steam operation is greatly influenced by the characteristics of the film 4. Ru. As shown in Fig. 2, the coating 4 is made by mixing very hydrophilic silica (SiO□) 13 fine particles in polyphenyl sulfide (p, p, 5) 12 which has melting properties, and the coating surface These fine particles are also exposed. Therefore, the surface area is also much larger than that of the p, p, s films alone.

Effects of the Invention As described above, the present invention exposes the silica particles on the surface of the film by applying and baking a film containing a mixture of P, P, S and silica particles on the inside of the vaporization chamber, thereby allowing the silica to interact with water. By increasing the contact surface area and exhibiting the highly hydrophilic properties of silica, even large amounts of water can be instantly vaporized. It was designed to eliminate it.
