This includes. Here, the exterior panel 100 may be a door that selectively shields the body 10.

The main body 10 includes a cavity (not shown) in which a cooking chamber of food is formed. The cooking chamber is a space in which food is cooked by at least one of microwave and heater rows.

In addition, the main body 10 is provided with an operation unit 15 for selecting a cooking or keeping warm mode or a cooking time of the cooking chamber. The manipulation unit 15 may be formed of a knob or a button type.

The exterior panel 100 is provided with a grippable handle 20. The user may grip the handle 20 to open and close the exterior panel 100. The exterior panel 100 may be rotatably coupled to the main body 10 or may be configured to be pulled out toward the front of the main body 10.

The exterior panel 100 is formed with an image 50 for implementing a delicate design. The image 50 may be provided in various shapes according to the pattern to be sketched.

The exterior panel 100 includes a glass member 110 that forms an overall appearance and a pattern forming unit 120 that is processed on an upper side of the glass member 110 to form a pattern for realizing the image. Included.

In addition, in the exterior panel 100, a predetermined color and a pattern are printed on the deposition processing unit 130 and an upper side of the deposition processing unit 130 so that a predetermined film is formed on the pattern forming unit 120. A print processor 140 (see FIG. 4) is included.

Here, the term "upper" is based on the direction shown in FIG. 2 and may be defined as a direction corresponding to the front side (front) of the exterior panel 100. On the contrary, the "lower side" may be defined as corresponding to the rear side (rear) of the exterior panel 100.

The glass member 110 may be made of a transparent material to enable perspective within the body 10. In addition, in order to prevent breakage of the exterior panel 100, the glass member 110 may include tempered glass processed.

The pattern forming unit 120 may be provided by fusion welding ink mixed with glass powder and paint on the glass member 110, and may be configured in various patterns according to the image 50 to be implemented.

The pattern forming part 120 includes a plurality of protrusions 121 and 122 protruding to a predetermined height above the glass member 110. In addition, the plurality of protrusions 121 and 122 include a first protrusion 121 and a second protrusion 122 that protrude to different heights.

Here, the first protrusion 121 has a height of "h1", the second protrusion 122 has a height of "h2". As such, the plurality of protrusions 121 and 122 may protrude to different heights, so that diffuse reflection may occur on the surface of the pattern forming unit 120.

When diffuse reflection occurs, the pattern forming unit 120 may be illuminated with different colors and brightness when viewed from different locations outside by light reflected at different angles. That is, a three-dimensional appearance such as a hologram may be implemented.

The deposition processor 130 forms a thin film on the surface of the glass member 110 provided with the pattern forming unit 120, and the irregular surface formed by the pattern forming unit 120 may be smoothed (flat). And a predetermined color may be implemented.

The print processor 140 is formed above the deposition processor 130 and may be implemented by a silk screen printing technique.

Hereinafter, an exterior panel processing process for implementing the image 50 will be described in detail.

3 is a front view illustrating a glass member in which a pattern forming unit and a deposition processing unit are formed according to a first embodiment of the present invention, and FIG. 4 illustrates a glass member in which a print processing unit according to a first embodiment of the present invention is formed. Front view.

3 and 4, the through-hole 115 to which the operation unit 15 is coupled is formed in the glass member 110 according to the embodiment of the present invention. The through hole 115 may be formed by using a punching method or the like on the glass member 110.

On the front portion 110a of the glass member 110, a pattern forming portion 120 for implementing the image 50 is formed.

The pattern forming unit 120 may be formed by plasticizing a glass material along the sketched shape in a state where a predetermined shape is sketched on the glass member 110.

In detail, the glass material may be formed as a transparent powder, and the glass material may be mixed with a colorless transparent paint.

The paint may include a resin (binder) of a liquid component to easily attach the glass material to the glass member 110 and a solvent for melting the resin to mix the glass material and the binder well.

The mixture of the glass material and the paint is mixed as a liquid such as ink (inked liquid), and the mixture is printed on the upper surface of the glass member 100 to form a predetermined pattern.

The glass member 100 may be dried for a predetermined time in a state where the pattern is formed, and then subjected to a process of being fired at a high temperature by being introduced into a firing furnace.

By the firing process, the glass material and the glass member 110 may be partially melted and fused together. In addition, the pattern forming part 120 may be provided in the glass member 110 by the fused glass material.

As described above, a plurality of protrusions 121 and 122 protruding from the upper surface of the glass member 110 at different heights are formed in the pattern forming part 120.

The pattern forming unit 120 has a three-dimensional texture such as a hologram due to the diffuse reflection caused by the protrusions 121 and 122. That is, since the reflection angle of the light transmitted from the outside to the pattern forming unit 120 is formed differently depending on the viewing direction, the light is reflected at the outside with different brightness.

After the pattern forming unit 120 is provided, a deposition process may be performed on the front portion 110a of the glass member 110. By the deposition process, a deposition processing unit 130 is formed on the glass member 110.

The deposition processor 130 may be formed by an “evaporation” process. The evaporation process may be performed by heating, dissolving, and evaporating a metal source using a high temperature heat to deposit a wafer, that is, the glass member 110.

The evaporation process utilizes the principle that when the metal is heated to a high temperature in a short time and evaporated, the evaporated metal sticks out and adheres to the low temperature base material surface to form a thin metal film.

In the evaporation process, an electron beam may be included as the evaporation means. That is, the metal or metal oxide of several layers may be heated, dissolved, and evaporated using an electron beam to form a film on the surface of the base material.

Meanwhile, the evaporation process is performed in a vacuum because the metal is oxidized to a high temperature, and thus may be referred to as vacuum evaporation.

When the deposition processing unit 130 is formed on the glass member 110 by the above process, the irregular surface of the pattern forming unit 120 may be smoothed, thereby improving the appearance of the exterior panel 100. The effect can be obtained.

In addition, the metal or metal oxide may include SiO ₂ or TiO ₂ .

When SiO ₂ is used as the source and deposited on the glass member 110, the color of the glass member 110 may change to approximately blue. On the other hand, when the TiO ₂ is deposited on the glass member 110, the color of the glass member 110 may be changed to silver.

As described above, when depositing on the glass member 110 using SiO ₂ or TiO ₂ as a source, since the color of the exterior panel 100 is realized in various ways, the color of the exterior panel 100 may be enhanced. It can be effective.

And, as the evaporation process is performed, the hardness of the glass member 110 is increased, the corrosion resistance is excellent, and the ability to cope with changes in temperature and humidity can be improved. That is, the glass member 110 may be prevented from being damaged under high temperature and high humidity conditions.

In addition, the exterior panel 100 may be prevented from being discolored or discolored even if it is exposed to air for a long time.

As described above, by performing glass plastic processing on the glass member 110 which is the main member of the exterior panel 100, a high-quality image 122 may be realized, and printing and deposition may be performed on the glass member 110. The treatment has the advantage that the strength of the exterior panel 100 can be reinforced and the influence on external environmental conditions can be minimized.

Another embodiment is proposed.

As a process of depositing the glass member 110, "sputtering" may be performed.

In the sputtering process, plasma is formed by a high voltage generated by a voltage generator, and the plasma ions collide with a target to attach metal atoms to a base material, that is, the surface of the glass member 110 to form a metal film. It is.

In detail, argon (Ar +) gas may be used for the plasma ions, and tin (Sn) may be used for the target. Therefore, the argon gas ionized by the high voltage collides with the tin, and the tin to be separated at this time may be attached to the glass member to form a metal film.

On the other hand, aluminum (Al) may be used for the target. In this case, the argon gas collides with the aluminum, and the separated aluminum may be attached to the glass member to form a metal film.

After the deposition processor 130 is formed, a print processor 140 is formed on the upper side of the deposition processor 130 by a printing process.

The print processing unit 140 may conceal at least a portion of the transparent glass member 110 by implementing a predetermined color, and may implement an auxiliary pattern (pattern) in addition to the pattern formed in the pattern forming unit 120. .

The print processor 140 includes a print layer 142, a reflective print layer 144, and a protective coating 146.

The print layer 142 may be printed by a silk screen printing method, also called a screen process.

The silk screen printing is made of a screen made of silk or chemical fiber in tension, and a portion of the non-fire line is covered with a paper or a glue material, and then the ink is applied thereon, whereby the ink is printed through the screen only. It is a printing method.

The silk screen printing is a printing method that can be applied to various base materials because the expression of color number is free and can be performed regardless of size or material.

On the other hand, in order to implement a pattern or pattern of a variety of colors to the printed layer 142 to have a plurality of degrees, for this purpose it is to perform a repeated printing operation in order according to the frequency.

The reflective printed layer 144 is provided on the upper side of the printed layer 142, so that the color printed on the printed layer 142 is exposed through the glass member 110 without being distorted. That is, the reflective printed layer 144 is configured to increase the color reflectance of the light passing through the printed layer 142.

In addition, the reflective printed layer 144 may act to cover the transparency of the glass member 110 together with the printed layer 142.

The reflective printed layer 144 is formed to a thickness of approximately 10 ~ 40㎛, so that most of the light passing through the printed layer 142 can be reflected. In addition, since the intensity of light reflected through the printed layer 142 is increased due to the improvement of the reflectance, the color of the printed layer 142 may be made clear.

By the configuration of the reflective printed layer 144, the gradation effect of the exterior panel 100 can be obtained.

The protective coating 146 may be made of an epoxy resin to protect the printed layer 142 and the reflective printed layer 144. The protective coating 146 may be formed on the reflective printing layer 144 by a printing method.

The print processor 140 may be formed at a portion other than the central portion of the front portion 110a. In the central portion of the front portion (110a) is formed an internal perspective portion 113 to the inside of the main body 10 can be seen from the outside.

The internal viewing part 113 may be formed to be transparent, and the print processor 140 may be formed to be opaque according to ink printing.

With reference to FIG. 5, the manufacturing method of the exterior panel which concerns on 1st Embodiment of this invention is demonstrated.

First, a paint is added to a glass material in powder form to form an ink solution, and then printed on an upper side of the glass member 110 to form a predetermined pattern. This pattern may have a shape corresponding to the image 50 formed on the exterior panel 100. This process is called a pattern formation step (S10).

In a state where a predetermined pattern is formed on the glass member 110 by the glass material, the glass member 110 is introduced into a firing furnace of a high temperature environment (about 600 ° C. to 700 ° C.) to be heated. Then, the glass member 110 and the printed pattern may be fused to each other. This process is called a firing step.

By combining the pattern forming step and the firing step, it may be referred to as glass plastic working, and the pattern forming part 120 may be formed by the glass plastic working (S20).

The deposition process is performed on the glass member 110 on which the pattern forming unit 120 is formed. When the source SiO ₂ or TiO ₂ is deposited on the glass member 110, the exterior panel 100 may have various colors. By the deposition treatment process, the deposition processor 130 may be formed (S21).

Thereafter, a printing process by a vitreous printing process is performed on the upper side of the deposition processor 130. By the printing process, the print processing unit 140 is formed.

The exterior panel 100 manufactured by the above method has various three-dimensional appearance, and an elegant appearance can be realized.

In addition, the exterior panel 200 includes a printed layer 242 and a reflective printed layer 244 that are silkscreen printed on the lower side of the glass member 210. The printed layer 242 and the reflective printed layer 244 may be collectively referred to as a "print processor."

The pattern forming part 220 includes a plurality of protrusions protruding upward of the glass member 210. The plurality of protrusions may protrude to different heights h3 and h4, and light passing through the glass member 210 may be diffusely reflected from the protrusions.

Therefore, depending on the position seen from the outside, the pattern forming unit 220 may be seen in a different three-dimensional feeling and color.

In addition, the description of the pattern forming unit 220, the deposition processing unit 230, and the printing processing units 242 and 244 uses the description of the first embodiment.
