Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an iron used for press-finishing clothes and the like.

[0002]

A conventional iron of this type includes a base and a heating means for heating the base, and the heating means heats the base and presses the hanging surface of the lower surface of the heated base against the cloth. Ironing is done while sliding. Generally, the base is made of aluminum or an aluminum alloy, and the bottom surface of the base has a tetrafluoroethylene resin (PTFE) or tetrafluoride resin for the purpose of obtaining corrosion resistance of this hanging surface and non-adhesiveness to glue. A surface treatment coating of a mixture of ethylene resin and polyether sulfone (PES) resin (polyether sulfone) is applied.

However, the conventional surface-treated coating film with a tetrafluoroethylene resin has a problem that the powder of the tetrafluoroethylene resin easily floats on the surface and the powder adheres to the cloth when ironed. Since this fluororesin powder looks whitish, this problem was remarkable especially when ironed on a black cloth.

In order to solve this problem, in recent years, there has been provided a composite plating film in which fine particles of a fluororesin are dispersed and contained in the plating, which is applied to the hanging surface. in this case,
The surface of the hanging surface is hard and smooth, and the fluororesin powder does not easily float on the surface, but lacks non-adhesiveness to the glue, so there is a problem that glue sticks easily when sticking and the maintenance of the hanging surface is troublesome. It was

Further, in the case where such a composite plating film is applied, the bottom member of the base and the base body are respectively formed at the time of manufacture, and the bottom member of the base is subjected to the composite plating, and then the bottom member is used as the base. The process of attaching to the main body is required. As described above, since the base is composed of two members, there is a problem that the manufacturing cost becomes extremely high due to factors such as a large number of steps and a large number of manufacturing facilities required.

The present invention is intended to solve such problems, and the hanging surface has non-adhesiveness with respect to the adhesive, and the fluororesin powder is not generated from the surface of the hanging surface at all. It is an object of the present invention to provide an iron that can be manufactured inexpensively without increasing the number.

[0007]

According to the iron of the present invention, a coating film of tetrafluoroethylene resin is formed to form a hanging portion, and the tetrafluoroethylene resin has a molecular weight of 1,000,000 or more. As a result, the straight chain of the tetrafluoroethylene resin molecule becomes longer and the bonds between the molecules of the tetrafluoroethylene resin become stronger, so the tetrafluoroethylene resin powder floats on the surface of the surface treatment film on the hanging surface. Hateful.

In the iron according to the second aspect of the present invention, the surface area per unit volume of the tetrafluoroethylene resin powder is increased by setting the particle size of the tetrafluoroethylene resin to 5 μm or less, and the surface-treated coating is formed. Since it can be strongly bound to other components, the tetrafluoroethylene resin powder does not easily float on the surface of the surface-treated coating on the hanging surface.

In the iron of the third aspect of the present invention, the base is made of a material selected from aluminum, aluminum alloys, iron and iron alloys, and these materials are excellent in thermal conductivity and relatively inexpensive. Therefore, it is possible to provide an inexpensive iron having excellent heat conductivity of the base.

In the iron according to the invention of claim 4, the coating contains the tetrafluoroethylene in polyether sulfone, so that the coating is hard, the sliding on the fabric is good, and the adhesive is non-adhesive. Since it can be formed to a high height, it is possible to provide an excellent iron that has good slipperiness with respect to cloth and high non-adhesiveness with respect to glue. Further, since the polyether sulfone resin has high adhesion to a metal material such as aluminum, it is possible to firmly adhere the surface-treated coating containing the powder of the tetrafluoroethylene resin dispersed therein to the base formed of the metal material. .

As shown in FIGS. 1 and 2, the lower surface of the base 22 is uniformly coated with a surface-treated coating 101 as a coating. The surface-treated coating 101 further includes a first layer 101a which is a base on the base 22 side and a second layer 10 which is a surface layer.
It has a two-layer structure with 1b. A hanging surface 102, which is a hanging portion, is formed on the surface of the second layer 101b. The surface-treated coating 101 is formed by dispersing powder of tetrafluoroethylene resin in polyether sulfone resin. The tetrafluoroethylene resin lacks adhesion to the metal material forming the base 22, but by powdering this into a polyethersulfone resin that has excellent adhesion to the metal material, and containing it, it becomes a metal material. The surface treatment film 101 containing a tetrafluoroethylene resin is firmly adhered to the formed base 22. That is,
The polyether sulfone resin plays the role of a primer and fixes the tetrafluoroethylene resin on the lower surface of the base 22.

The first layer 101a of the surface-treated coating 101 is formed of a resin having a main component of polyethersulfone resin, for example, 90% of polyethersulfone resin and 10% of tetrafluoroethylene resin. The second layer 101b of the surface-treated coating 101 is made of a resin containing tetrafluoroethylene resin as a main component, for example, tetrafluoroethylene resin of 80% and polyethersulfone resin of 20%. The molecular weight of the tetrafluoroethylene resin dispersedly contained in the surface treatment film 101 is 1,000,000 or more, and the particle diameter of the tetrafluoroethylene resin powder is 5 μm or less. If the molecular weight of the tetrafluoroethylene resin is less than 1,000,000 or the particle size of the powder is more than 5 μm, the powder of the tetrafluoroethylene resin is likely to rise on the surface of the hanging surface 102, which is not preferable. Actually, the particle size of the tetrafluoroethylene resin powder is set to 5
When the particle diameter was 10 μm, almost no powder came out, whereas when the particle diameter was 10 μm, whitish powder of tetrafluoroethylene resin came out on the surface of the hanging surface 102. Further, in the conventional iron having less than 1 million tetrafluoroethylene resin, the powder of the tetrafluoroethylene resin easily floats on the surface of the hanging surface 102, whereas when the molecular weight is 1 million or more, the powder almost floats. It didn't come.

In the step of forming the surface treatment coating 101 on the lower surface of the base 22, a solvent is added to the resin material of the first layer 101a to make it liquid, and this is sprayed by, for example, a base.
The lower surface of 22 is coated, and then a solvent is added to the resin material of the second layer 101b to form a liquid, which is coated by, for example, a spraying means, and further heated and baked at about 400 ° C. to obtain a surface-treated coating 101. .

Next, the operation of the above configuration will be described. At the time of ironing, first, the power cord 73 is pulled out from the cord reel device 25, which is a device for winding the power cord 73, and is connected to a commercial AC power outlet. Then, the base 22 is heated by the heater 28, and the base 22 is pressed against clothes, for example, to smooth the wrinkles of the clothes. At that time, the temperature controller 51 controls the energization of the heater 28 according to the setting by the temperature adjusting cam 54, whereby the temperature of the base 22 is adjusted. And the heater 28
When is energized, the pilot lamp 56 is turned on, so that the user can know that the heater 28 is energized. At that time, the light of the pilot lamp 56 can be seen through the transparent handle body 24. Further, when the nozzle portion 63 of the cassette tank 38 is opened, water is supplied from the cassette tank 38 to the vaporization chamber 29 of the base 22 through the water supply passage 61, where the heat of the base 22 evaporates the water. Steam or steam is generated. This steam spouts from the spout 30 to the clothing. After using the iron, the power cord 73 pulled out from the outlet is wound around the cord reel device 25 and stored. For that purpose, the control release button 76 is pushed. When the phases match, the power of the mainspring 73 causes the cord reel 72 to rotate, and the power cord 73 is wound around the cord reel 72. At this time, the winding position of the power cord 73 on the cord reel 72 can be adjusted by holding the wound power cord 73 by hand and adjusting the position.

101 is hard, can be formed on the cloth well, and has high non-adhesiveness with respect to the adhesive, so it has good slippery with respect to the cloth, has high non-adhesiveness against the adhesive, and can reliably prevent the glue from sticking. It is possible to provide an excellent iron having the hanging surface 102 with high corrosion resistance. Further, since the polyether sulfone resin has high adhesion to a metal material such as aluminum, the base 22 formed of a metal material has a surface treatment coating 101 containing a powder of tetrafluoroethylene resin dispersed therein.
Can be firmly adhered to.

Further, as an effect of the embodiment, the main component of the first layer 101a on the base 22 side of the surface treatment coating 101 is polyethersulfone resin, and the main component of the second layer 101b on the hanging surface 102 side is tetrafluoride. By using the ethylene resin, it is possible to firmly adhere the surface-treated coating 101 to the base 22 by utilizing the characteristics of the polyether sulfone resin on the base 22 side, while the characteristics of the tetrafluoroethylene resin on the hanging surface 102 side. It is possible to improve the non-adhesiveness of the hanging surface 102 with respect to the adhesive, the corrosion resistance, and the like.
