Also, on a decoration model (D′): it is suitable that the parts irreflection or relief are formed as a trilatral lattice structure is rougher than the parts that reflection or intaglio are formed, and for sure, the opposite structure is possible.
On the surface of a front door frame (72) that a decoration part is formed, a metallic textured a chromium gliding layer (122) is formed.
And, a rounded plate form capable of covering the entire external surface is formed above the chromium gliding layer (122), and a transparent textured protective coating (125) can be worn.
Reference on the manufacturing method of a door of a drum washing machine will now be made in detail to the preferred embodiment No. 6 of the present invention.
Firstly, on the texture forming process, a decoration model (D′) having a lattice structure is formed on an injection mold (124) of a front door frame so as a decoration part (D) to be formed on the front surface of an injection molded front door frame (72). (S11, S12)
That is, a decoration model (D′) is formed by an etching process on a cavity (124A) one of the injection molds (124) of a door frame (72). Usually for a corrision management method, a photo etching technic is used to form a decoration model (D′), on a cavity (124A) of a injection mold (124).
On the injection process, a front door frame (72) is injection molded as using an injection mold formed a decoration model on the texture forming process (S13).
Therefore, a front door frame is injection molded from an injection mold (124) in a condition that a decoration part (D) having a latticed structure on the front surface is completed in one body. The major material of a door frame (70) is a plastic material that the special injection quality is excellent, the weight is low, and which is having a certain level of strength.
On the gliding process, a metallic gliding which inflicts the more of a high classic sense is completed on the external aspect of a door frame which is injected on the injection process. (S14, S15)
As the gliding material, chromium that a fine sense and inner abrasion quality are superior is broadly used. A luster of metallic quality is polished by the chromium gliding layer (122) as the front door frame (72), inflicts a high classic textured sense compared with a plastic surface.
Therefore, a door (60) of a drum washing machine forms a decoration part (D) on the surface of a door frame (70), and a chromium is glided on the decoration part (D), so the external aspect of a door (60) becomes high-classic.
After that, after coating the protection film (125) on a decoration part (D) of a door frame (72) which is manufactured as afore-mentioned, a door (60) is completed as assembling a door glass (90) on a center hole (70A) of a door frame (72). (S16)
For reference, the same reference numbers are given for the same or similar composition elements with the composition of the preferred embodiment NO. 1 and the detailed descriptions are omitted.
As illustrated on

A gliding layer (132) with metallic material like chromium is formed on a front door frame (72), and a decoration part is formed on the gliding layer (132).
A decoration part (D) is formed an intaglio/relief structure by the corrosion management method through the photo etching or a laser processing method on the chromium gliding layer (132), it is suitable for the relief part to have a irreflected surface.
If a door frame (72) is formed on the surface of a decoration part (D), a protection coating (136) is worn to protect a decoration part (D).
A protection film is formed as a transparent texture capable of showing a decoration part (D), the color and polish can be controlled according to a user's taste and trends.
Reference on the manufacturing method of a door of a drum washing machine will now be made in detail to the preferred embodiment No. 7 of the present invention.
Firstly, as injection molded with a metallic texture on a door frame (70) which is injected with a plastic texture on the gliding process, raise the sense of quality of a door. (S21, S22) That is, on the door (60), glide on a front door frame (72) among the door frames (90) with a metallic texture so as no to decrease the fine view by the plastic textured sense of a door frame (70).
For the. gliding material, chromium which gives the consumers the high classic textured sense, and that the abrasion quality is superior, chromium is used typically.
On the texture forming process, as forming a decoration part (D) continued with intaglio and relief structures by etching or I on the front part of a glided front door frame on the gliding process (72) (S23, S24).
By the processed decoration part (D), the front external aspect of a door (60) capable of having a high classic texture and preventing the glaring, so the marketability of a drum washing machine is improved.
On the coating procession, a protecting coating (136) is worn on the front surface of the decoration part (D) of the front door frame (72) on the texture forming process to prevent etching and damages.
The natural gift sense and hardness of the chromium used for gliding of a front door frame (72) are excellent, but the adhesion property on the surface of plastic is low, usually, after gliding copper on the surface of the front door frame (72), glide chromium on the copper gliding layer (134).
That is, as gliding copper which is relatively glided well on the plastic texture of a front door frame (72), after forming a copper gliding layer (134), forming a chromium gliding layer as gliding chromium on the surface of a copper gliding layer (134).
At this time, if process to form a decoration part (D) on the texture forming process, as the chromium layer is worn off, a part of copper gliding layer (134) is bared out of exterior. As copper is different to chromium, a metal which is corroded well, the corrosion which is progressed on the bared copper gliding layer (134), on the contrary, decrease the external aspect of a door (60).
Therefore, to prevent the corrosion condition, the corrosion resistance protecting coating (136) is covered on the front surface of a front door frame (72) a decoration part is formed.
Also, the corrosion resistance protecting coating (136) prevents the situation that a decoration part (D) is injured or damaged by the exterior impact, make the surface of the continued by the intaglio and relief which could be rough smooth.
On the other hand, as a corrosion resistance protecting coating (136) is composed of a transparent texture, the high classic sense of a door (60) in order to the gliding of chromium and form of a decoration part (D) is visually transmitted to the consumers.
As the color and the luster of a corrosion resistance protecting coating (136) can be controlled according to the materials and the coating method, giving the proper texture quality on the front surface of a door frame (70) according to the necessity.
On the other hand, the manufacturing method of a washing machine and a door of a washing machine in accordance with the present invention are explained as referring to the illustrated figures, the present invention isn't limited to the preferred embodiment, the various transformation is surely possible on the extent of the technique abstraction of the invention.
