Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments in which the spirit of the present invention is presented, and other embodiments included in the spirit of the present invention or other inventions which are degenerate by addition, modification, or deletion of other components are easily provided. Can suggest.

The film for home appliances according to the present invention may be variously applied to an air conditioner, a washing machine, an oven and the like, but the following description will be given by way of example applied to a refrigerator for convenience of explanation and understanding.

1 is a front view showing the appearance of a refrigerator employing an adhesive film for home appliances having a bubble discharge structure according to the present invention with reference to the drawings, the appearance of the refrigerator 100 is formed in a substantially rectangular parallelepiped shape, forming a storage space The main body is divided into a refrigerator compartment and a freezer compartment.

1 illustrates an example of a side by side type refrigerator (Side by side type) in which a refrigerating compartment and a freezer compartment are divided into left and right sides, and the present invention includes a freezer compartment as well as a side by side type refrigerator. Naturally, it can be applied to various forms such as a top mount type and a freezer type which are provided below.

The front surface of the main body, that is, the front surface of the refrigerating chamber and the freezing chamber is formed to be opened, and the opened front surfaces of the refrigerating chamber and the freezing chamber are configured to be selectively shielded by the door 110 mounted to rotate left and right, respectively.

The exterior of the refrigerator 100 main body and / or the door 110 is formed of a color steel sheet or tempered glass, and has various colors and patterns. In addition, the main body and / or the door 110 is provided with an exterior part 140 composed of a decor member 120 and a handle 130.

The deco member 120 further enhances the appearance of the refrigerator 100, and is mounted around the corner of the main body of the refrigerator 100 and / or around the door 110. The deco member 120 and the handle 130 are formed of a base material by a glass fiber reinforced plastic (FRP) material and, if necessary, a film (eg, aluminum) on a part or the whole of the surface to have a texture of a metal such as aluminum ( 200) is attached. The base material and the film 200 will be described in more detail below.

2 is a cross-sectional view showing a cross-sectional shape of the adhesive film for home appliances having a bubble discharge structure according to the present invention, Figure 3 is a partial cutaway showing a state in which the adhesive film for home appliances having a bubble discharge structure according to the present invention is attached. Perspective view.

Referring to these drawings, the exterior part 140 is composed of a base material forming a shape and a film 200 showing a texture.

The base material is formed of a glass fiber reinforced plastic to form a shape and will have a different configuration depending on the degree of strength is required.

First, the glass fiber reinforced plastic forming the base material of the exterior part 140 such as the decor member 120, which requires relatively low strength, is composed of 20 to 40 wt% glass fiber and 60 to 80 wt% resin. At this time, the weight ratio of the glass fiber affects the strength of the glass fiber reinforced plastic, and when it is 20wt% or less, thermal deformation occurs in the use environment of the home appliance (approximately -30 ° C. to 60 ° C. temperature range) or breakage due to continuous use. This will occur.

In this case, the glass fibers are cut and formed to have a length of about 3 mm, mixed with thermoplastic resins such as ABS (Acrylonitrile butadiene styrene copolymer), SAN (Styrene acrylonitrile copolymers) and nylon (Nylon). Will form. Preferably, the base material is extruded to a thickness of about 1.2 mm or more.

When the film 200 to be described below is attached to the base material, the front surface of the base material to which the film 200 is attached is re-coated by double extrusion to form an attachment surface. The adhesion surface is uniformity of the base material due to the re-coating of the resin, not only makes the attachment of the film 200 more smooth, but also makes the appearance more beautiful.

On the other hand, the glass fiber reinforced plastic forming the base material of the exterior parts 140, such as the handle 130 to form a relatively high strength portion is composed of 50 ~ 70wt% glass fiber and 30 ~ 50wt% resin. At this time, the weight ratio of the glass fiber affects the strength of the glass fiber reinforced plastic, and when it is 50 wt% or less, the strength is lowered than the required strength, which causes breakage due to continuous use.

Glass fibers constituting such a base material is arranged in a unidirectional fibrous structure, is formed in the form of a mesh (Met type) such as cloth and is composed of at least one sheet. When the glass fiber of the base material is composed of a plurality of sheets, each glass fiber is laminated so as to be superimposed on one another, and formed to be more resistant to deformation and shrinkage.

And, the glass fiber is mixed with a thermosetting resin such as polyester (Polyester) to form the base material, it will be desirable to be molded to a thickness of approximately 1.5mm or more.

On the other hand, a portion of the outer surface of the handle 130 and the decor member 120 or the film 200 to show a metal texture is further attached.

The film 200 is attached to the surface of the base material so that the exterior parts 140 such as the decor member 120 and the handle 130 have a texture of a metal such as aluminum. Make sure that at least some of them have a metal-like texture. In addition, the film 200 is provided as a lower layer 210 so that a unique texture appears on the exterior part 140 and an upper layer 220 provided on the lower layer 210 to protect the lower layer 210. It is composed.

The lower layer 210 may be an attachment layer 230 to allow the film 200 to be attached to the exterior component 140, and a decoration layer 240 to realize a texture of a metal on the attachment layer 230. It is composed of

Looking at this in more detail, the adhesion layer 230 is formed of PET (Polyethylen therephthalate) or PVC (PVC: Polyvinyl chloride) material, is formed of a thickness of approximately 10 ~ 50㎛ of the surface of the base material It is possible to conceal the uneven side and at the same time to reinforce the strength of the film (200).

That is, the adhesion layer 230 is the surface of the base material, which is the skin adhered to the film 200 is scratched or damaged during processing is uneven surface due to the uneven surface of the film 200 when the film 200 is attached The surface of the substrate may be curved, but the surface of the base material, which is the skin deposit, is completely covered by the adhesion layer 230 formed of the flexible PTI material or FBC material, thereby concealing surface defects of the base material. The film 200 can maintain a smooth surface.

On the other hand, a plurality of guide grooves 232 are formed on the lower surface of the adhesion layer 230. The guide groove 232 is for discharging the foreign matter interposed between the bubble or film 200 and the decorative parts generated during the attachment of the film 200, the detailed configuration will be described again below.

In addition, the adhesion layer 230 and the exterior component 140 are adhered by an adhesive 250. The adhesive 250 is a two-component adhesive 250 is a mixture of polyurethane and epoxy is used, the adhesion of the adhesive layer 230 and the exterior part 140 by the use of such an adhesive 250. It can be done. In addition, as the adhesive 250 is filled in the inside of the guide groove 232, the entire area to which the adhesive 250 is applied may be increased, thereby improving adhesion to the exterior part 140.

On the other hand, the decorative layer 240 is formed on the upper surface of the adhesion layer 230. The decorative layer 240 is to allow the texture of the film 200, in particular, the intrinsic texture of the metal and / or processed texture of the metal to appear, it is composed of an aluminum layer and a resin layer.

The aluminum layer 242 allows the film 200 to exhibit the texture of a metal material, and is formed of an aluminum thin plate having a thickness of approximately 20 to 200 μm. The aluminum layer 242 allows the film 200 to exhibit a texture such as intrinsic color of aluminum, thereby allowing the exterior part 140 to have a metallic texture.

The resin layer 244 is formed on the upper surface of the aluminum layer 242. The resin layer 244 protects the surface of the aluminum layer 242 and makes the auxiliary texture of metal appear so as to improve the texture of the exterior part 140. It is formed to a thickness of approximately 10 ~ 50㎛.

Since the resin layer 244 is made of a relatively flexible material and can be easily processed, various patterns may be formed. In addition, the resin layer 244 may be formed in various colors as needed, or may be formed in a transparent or semi-transparent manner, in addition to the inherent texture of the metal. To help you get it.

Meanwhile, an upper layer 220 is formed on an upper surface of the lower layer 210, that is, an upper surface of the decoration layer 240. The upper layer 220 is to improve the scratch resistance and hardness of the film 200, is formed by a general UV coating (UV) coating or thermosetting coating, and is formed to a thickness of approximately 5 ~ 15㎛.

The upper layer 220 is preferably formed of a transparent material, the upper surface of the lower layer 210 is protected by the upper layer 220. The upper layer 220 is a coating layer that completely shields the upper surface of the lower layer 210.

As the film 200 is completely attached to the base material, the exterior part 140 may not only have strength such as aluminum but also have a texture such as aluminum, thereby realizing various textures that aluminum may have. It can be represented closely.

As such, when the film 200 is attached to the exterior component 140 of the home appliance, the exterior component 140 may be reduced in weight than when the real aluminum is used. This is possible by molding the exterior part 140 from glass fiber reinforced plastic material as well as the use of the film 200.

Compared with aluminum, glass fiber reinforced plastic has a higher specific strength, thereby making it possible to manufacture the exterior part 140 having the same strength lighter, and the handle 130 formed of glass fiber reinforced plastic is made of aluminum. Compared to 130, it is possible to produce lighter while having the same strength, and by attaching the film 200 it is possible to realize the texture of aluminum as it is.

Meanwhile, when the film 200 is attached to the exterior part 140, bubbles may be generated between the film 200 and the exterior part 140 due to immature work or thermal expansion, or fine foreign matters may be interposed. . Such bubbles and foreign matters are discharged through the guide grooves 232 after the film 200 is attached. Hereinafter, the guide groove will be described in more detail with reference to the accompanying drawings.

Figure 4 is a perspective view showing the back shape of the first embodiment of the adhesive film for home appliances having a bubble discharge structure according to the present invention, referring to the drawing, the guide groove 232 is formed on the lower surface of the lower layer 210 .

The guide grooves 232 are formed in plural at the predetermined intervals, and are formed recessed upward (downward in Figure 4). The guide groove 232 is formed to extend from one side end to the corresponding other end, and thus both ends of the guide groove 232 are formed to be opened. Therefore, when the film 200 is attached, both ends of the guide groove 232 are formed to be opened in the outward direction, and bubbles or foreign matter can be discharged to the outside through the opened portion.

A plurality of such guide grooves 232 are formed at regular intervals, the width of the guide grooves 232 is adjusted according to the viscosity of the adhesive 250. That is, the lower the viscosity of the adhesive 250, the narrower the width of the guide groove 232.

In addition, the number of the guide grooves 232 may be provided in number to facilitate the smooth discharge of bubbles and foreign matter and adhesion, it will be preferable to form an appropriate number in consideration of the deformation of the surface shape at the time of attachment.

On the other hand, the guide groove 232 may be formed in any direction of the horizontal direction or the longitudinal direction on the lower surface of the attachment layer 230.

However, in order to facilitate the discharge of bubbles or foreign matters, it may be preferable to extend in the short axial direction of the film 200 as shown in FIG. 6. This is to facilitate the discharge of bubbles and foreign matter by forming the guide groove 232 in a short length in the horizontal and vertical directions according to the shape of the exterior component 140.

In the drawing, for example, the cross-sectional shape of the guide groove 232 is formed in a substantially rectangular shape, but as necessary, the guide groove 232 may have various shapes such as an upper surface formed in an arch shape, a semicircle shape, or a wedge shape. It will be changeable.

Figure 5 is a perspective view showing the back shape of the second embodiment of the adhesive film for home appliances having a bubble discharge structure according to the present invention, referring to the drawing, the guide groove 232 formed on the lower surface of the attachment layer 230 The plurality is formed in the horizontal or vertical direction, these plurality of guide grooves 232 are formed to cross each other.

That is, the guide grooves 232 are formed to extend toward both ends corresponding to each other, a plurality of guide grooves 232 arranged at regular intervals are formed to cross each other to be orthogonal to each other.

Therefore, the lower surface of the lower layer 210 has a substantially checkered shape, and the application area of the adhesive 250 can be further increased, as well as the bubbles or foreign matters are more easily discharged.

The plurality of guide grooves 232 may be formed to be orthogonal to each other, and may be formed to be inclined by a predetermined angle as necessary.

With reference to the drawings with respect to the action of the adhesive film for home appliances having a bubble discharge structure according to the present invention having the configuration as described above are as follows.

6 is a state diagram showing a bubble discharge state of the adhesive film for home appliances having a bubble discharge structure according to the present invention, referring to the drawing, that is, the lower surface of the lower layer 210 of the film 200, that is, the adhesion layer 230 After applying the adhesive 250 to the lower surface of the) to adhere the film 200 to the surface of the exterior component 140.

At this time, when the heat is applied for the adhesion of the film 200 and the exterior component 140, the film 200 is bonded by the adhesive 250, wherein the coating area of the adhesive 250 is relatively large The film 200 may be in close contact with the surface of the exterior component 140.

In this case, when the exterior part 140 is the handle 130 as shown, the handle 130 has a jaw width is relatively shorter than the upper and lower width, the guide groove 232 of the handle 130 It is molded so as to extend in the width direction, that is, the left and right directions, or cut and attached. Of course, when the guide grooves 232 are formed to intersect with each other, the film 200 may be attached regardless of the direction.

In addition, the film 200 is structurally somewhat flexible by the guide groove 232, and thus, the film 200 may be completely in contact with the surface of the handle 130.

On the other hand, after the film 200 is attached to the film 200 and the outer part 140, after checking whether the bubble or foreign matter has occurred, if there are bubbles or foreign matter, push the hand or bubbles or foreign matter in the guide groove 232, and pushes in the next open direction so that the bubble or foreign matter is discharged to the outside.

If there is a very small foreign matter in the guide groove 232 may be concealed foreign matter inside to allow the foreign matter is accommodated inside the guide groove 232 without discharging to the outside as needed.

On the other hand, in addition to the contents described in the above embodiments, the film 200 may be formed of one or two resin layers, without forming a metal layer such as a separate aluminum layer 242, and in this case, a guide groove ( The shape of 232 will be as described above. As such, the number and material of layers constituting the film 200 may be variously changed.
