Description

  The present invention relates to a refrigerator, and more particularly to a configuration of a door using a glass outer surface material.

  In general, a door that opens and closes the opening of a refrigerator for home use is provided on the front of the refrigerator, and the front side of the door greatly affects the design of the entire refrigerator. Will also be affected.

  Therefore, in recent years, glass has been adopted as a decorative plate for the exterior material of the door, which is a design, and the glass is often decorated with a film that has been painted or printed, colored or patterned. . In particular, tempered glass is used as the glass. However, when the tempered glass is damaged by a strong impact, the entire tempered glass is momentarily broken. At this time, the tempered glass has a feature of breaking into pieces.

  Therefore, Patent Document 1 discloses a configuration in which a resin film is attached to glass for the purpose of preventing scattering when the glass is broken.

JP 2014-52157 A (Page 12, FIGS. 5 and 8)

  As shown in Patent Document 1 (see FIG. 8), the outer surface material of a conventional refrigerator door is scattered on glass that has been subjected to print coating, or glass that has been decorated and printed and pasted with an adhesive material. It is constructed by attaching a prevention film.

  The outer surface material is bonded to the frame member to constitute the surface of the door. As for the outer surface material, the anti-scattering film is attached to the entire back surface side of the door, and an adhesive means is attached on the anti-scattering film to bond the outer surface material and the frame member. That is, the outer surface material is fixed to the frame member via the scattering prevention film.

  The adhesive material between the anti-scattering film and the outer surface material is optically uniform and transparent from the viewpoint of ensuring the display capability of the display installed on the refrigerator door and improving the visibility, and does not cause peeling or bubbles. Therefore, OCA tape (highly transparent adhesive tape) and PSA tape (pressure-sensitive adhesive tape) are used. Generally, OCA tape and PSA tape have an adhesive strength of 4 to 6.5 N / cm. Moreover, the adhesion means when adhering the outer surface material to the frame member via the anti-scattering film is such that the use environment of the refrigerator is not peeled off even in a hot and humid environment or a temperature change (for example, −30 ° C. to + 60 ° C.) A strong bonding method is selected. For example, a double-sided tape having an adhesive strength of 8.5 N / cm or more is used. The unit of adhesive strength “N / cm” indicates the adhesive strength per 1 cm length of a 10 mm wide tape.

  When an external force is applied to drop the outer surface material from the door, the adhesive force between the anti-scattering film and the outer surface material is bonded by the bonding means between the anti-scattering film and the frame member attached to the outer surface material. Power is low. Therefore, the anti-scattering film is peeled off from the external material prior to the bonding means between the anti-scattering film attached to the external material and the frame member. At that time, the scattering prevention film remains on the frame member, and only the outer surface material constituting the door surface falls off from the door. In other words, even if the adhesion force of the adhesive means used to fix the outer surface material with the anti-scattering film attached is high, the adhesive force of the adhesive material between the anti-scattering film and the outer surface material is low, so it depends on the adhesive force And the intensity | strength and durability with respect to dropping from the glass door which comprises an outer surface material will become low.

  The present invention has been made to solve the above-described problems, and prevents the scattering of fragments when the glass used as the outer surface material is broken, and the strength against dropping of the glass constituting the outer surface material from the door. And it aims at providing the refrigerator which can make durability stronger than before.

The refrigerator according to the present invention includes a main body having a front opening and a door that opens and closes the front opening, and the door is bonded to the frame member and the frame member. The outer surface material made of glass constituting the inner surface material, the inner surface material fixed to the frame member and constituting the rear surface of the door, the anti-scattering film adhered to the rear surface side of the outer surface material, the outer surface material and the frame member And a heat insulating material filled in a space surrounded by the inner surface material, and the outer surface material includes a first adhesion region to which the anti-scattering film is adhered, and a second material to which the frame member is directly adhered. An adhesive region.

  According to the refrigerator according to the present invention, by providing the second adhesion region that directly adheres the outer surface material and the frame member, an external force that drops the outer surface material from the door is not applied to the anti-scattering film. Thereby, peeling of an outer surface material and a scattering prevention film is lost, and even when an outer surface material is damaged, a safe structure can be obtained without scattering. Moreover, since the glass and the frame member are directly fixed to the second adhesion region, the force for fixing the outer surface material to the frame does not depend on the adhesion force of the anti-scattering film. Thereby, the fixed strength and durability with respect to the external force which drops the outer surface material from the door can be made stronger than those of the prior art.

It is a perspective view of the whole refrigerator which concerns on Embodiment 1 of this invention. It is an exploded view of the door of FIG. It is a figure of the back surface of the outer surface material of the door of FIG. It is sectional drawing of the door of FIG.

Moreover, in the following drawings, the relationship of the size of each component may be different from the actual one. In addition, “upper”, “lower”, “left”, and “right” used below are directions when the refrigerator is viewed from the front.

Embodiment 1 FIG.

As shown in FIG. 1, the refrigerator according to the first embodiment includes a main body 1, the main body 1 has an opening on the front surface, and a door 2 that closes the front opening of the main body 1 so as to be freely opened and closed is provided. It has been.

  As shown in FIG. 2, the door 2 includes an outer surface material 3 including a glass 7 serving as an exterior design surface, an inner surface material 4 on the side of a storage room for storing food and beverages, and a frame member 5. Prepare. The frame member 5 includes an upper frame member 5a and a lower frame member 5b having claw shapes, a right frame member 5c and a left frame member 5d connected to the claw shapes (not shown) of the upper frame member 5a and the lower frame member 5b, And connecting them together to form a frame. The door 2 includes a frame member 5 connected and configured in a frame shape, an outer surface material 3, an inner surface material 4, and a foamed urethane 6 that is a heat insulating material filled in a space surrounded by them.

  In the first embodiment, the upper frame member 5a and the lower frame member 5b are provided with claw portions (not shown), and the right frame member 5c and the left frame member 5d are provided with groove portions (not shown). However, the reverse configuration may be used. Further, the frame member 5 is not limited to the configuration in which the claw portion is engaged with the groove portion to form a frame shape as described above, and may be, for example, an integral frame-shaped frame member.

FIG. 3 is a diagram of the back surface of the outer surface material 3. That is, it is a view of the outer surface material 3 as viewed from the side bonded to the frame member 5.
FIG. 4 is a cross-sectional view of the door 2, and particularly a cross-sectional view showing the periphery of a portion where the outer surface material 3 and the frame member 5 are bonded.
In particular, tempered glass is used for the glass 7 constituting the outer surface material 3. In order to improve the design of the refrigerator, the glass 7 is printed or a decorative film is attached. The outer surface material 3 in the first embodiment is printed. An anti-scattering film 8 (for example, a film made of PVC) is attached to the outer surface material 3 to prevent the fragments from scattering when the glass 7 is broken. The adhesive material 9 of the anti-scattering film 8 to be attached to the printed coating surface of the glass 7 constituting the outer surface material 3 is optical from the viewpoint of ensuring the display capability of the display installed on the refrigerator door and improving the visibility of the display. Use a uniform and transparent material that does not cause peeling or bubbles. For example, an OCA tape (highly transparent adhesive tape) or a PSA tape (pressure-sensitive adhesive tape) having an adhesive strength of 4 to 6.5 N / cm is used. In addition, the case where the display installed in the refrigerator door 2 is a touch panel is also included.

  As shown in FIG. 3, the anti-scattering film 8 attached to the glass 7 is attached outside the range of 30 mm from the outer edge of the glass 7 to form the first adhesive region 13. A double-sided tape 10 is applied to an area where the anti-scattering film 8 is not applied to form a second adhesive region 14 for adhering the glass 7 and the frame member 5, and as shown in FIG. 4, the glass 7 and the frame member 5. Are directly attached with the double-sided tape 10. The second adhesion region 14 usually needs a width of 15 mm to 20 mm, but may take a value larger than that, and can take a range of 15 mm to 30 mm from the outer edge of the outer face material 3. For attaching the outer surface material 3 and the frame member 5, it is preferable to use a double-sided tape (adhesive strength of 8.5 N / cm or more) which does not peel off even in a hot and humid environment (outside temperature 50 ° C., humidity 90%). However, for example, a liquid adhesive having an adhesive strength of 8.5 N / cm or more may be used. The double-sided tape 10 corresponds to the bonding means in the present invention.

  By adopting such a configuration, even when the glass 7 is broken when the outer surface material 3 is attached to the door 2, the anti-scattering film 8 is attached to the first adhesion region 13, and the second adhesion is performed. Since the double-sided tape 10 is affixed to the region 14, the glass 7 is not scattered. Moreover, since the outer surface material 3 and the frame member 5 are directly bonded to each other in the second bonding region 14, the fixing strength and durability against an external force that causes the outer surface material 3 to drop off from the door 2 can be made higher than those of the related art. Furthermore, since the anti-scattering film 8 does not peel from the outer surface material 3 when the outer surface material 3 is dropped from the door 2, a structure in which the glass 7 is not scattered even if the outer surface material 3 is damaged due to the dropping is obtained.

Embodiment 2. FIG.
In the first embodiment, as shown in FIG. 3, the range of 30 mm from the outer edge of the outer surface material 3 is defined as the second adhesion region 14. However, in the present embodiment, the second adhesion region 14 can be limited to a part. State.

  Compared to the first embodiment, deformation is caused by an external force in particular, only on the side of the door 2 where the handle is disposed, or only on the long side of the door 2 having a longitudinal direction of 600 mm or more, such as a revolving door, or both The second bonding area is provided. The shape of the outer surface material 3 is not limited to a rectangle, and may be, for example, a quadrangle, other polygons, a circle, or an ellipse. Moreover, a hole can be provided in a part of the shape of the outer surface material 3, or a part of the shape of the outer surface material 3 can be cut out in another shape. The second adhesive region is effective for peeling the double-sided tape 10 when it is provided at a location where the deformation amount is large in the shape of the outer surface material 3. However, it is a condition that the adhesive force of the double-sided tape 10 exceeds the force of peeling the double-sided tape 10 caused by the deformation of the outer surface material 3.

  By adopting such a configuration, even if the second bonding region 14 for directly bonding the outer surface material 3 and the frame member is limited to be smaller than that of the first embodiment, the glass 7 is broken as in the first embodiment. However, a structure in which the fragments are not scattered is obtained, and the fixing strength and durability of the outer surface material 3 similar to those of the first embodiment can be obtained.

Embodiment 3 FIG.
In the first embodiment, the double-sided tape 10 is used as a means for adhering the outer surface material 3 and the frame member 5, but in this embodiment, the case where the double-sided tape 10 is made of a stretchable material will be described.

  As a factor that promotes the separation between the outer surface material 3 and the frame member 5 shown in FIG. 2, in addition to the deterioration of the double-sided tape 10 in the high-temperature and high-humidity environment, the door itself is warped, twisted, etc. There is. For example, the door itself is deformed by warpage and deformation of each component of the door 2 and contraction of the urethane foam 6 filled in the door. Assuming a low outside air temperature (about -5 ° C) in winter, etc., if the door 2 is placed in the low outside air temperature environment immediately after filling with urethane foam, the warpage of the door 2 is the maximum immediately after filling with urethane foam. It may occur 2 to 3 mm.

  In this case, a double-sided tape made of a stretchable material is used as the double-sided tape 10 shown in the first embodiment for the deformation of the door 2. For example, when the warp of the door 2 occurs up to 2.5 mm immediately after filling with urethane foam, the double-faced tape 10 has a thickness of 2 mm and the base material of the double-faced tape 10 has a tensile elongation of 50 to 100%. Then, since the base material of the double-sided tape 10 can follow the deformation of the door 2, the peeling load on the adhesive surface can be reduced. Thereby, the fixed strength and durability against an external force that causes the outer surface material 3 to fall off the door 2 can be made higher than in the first embodiment. The base of the double-sided tape 10 is provided on the condition that the adhesive force of the double-sided tape 10 exceeds the force of peeling the double-sided tape 10 caused by the deformation of the outer surface material 3 and the frame member 5 and the elongation of the base material of the double-sided tape 10. An appropriate value can be selected as the tensile elongation value of the material.

Embodiment 4 FIG.
In the present embodiment, a case where the second and third embodiments are combined will be described.

  In contrast to the third embodiment, the double-sided tape 10 on the side where the handle of the door 2 is arranged and the double-sided tape 10 on the long side of the door having a longitudinal direction of 600 mm or more, such as a revolving door, which cause deformation due to external force. The effect of preventing peeling of the adhesive surface that can withstand actual use can also be obtained by substituting it with a double-sided tape having elasticity. In this case, it is possible to obtain a fixing strength and durability against an external force that causes the outer surface material 3 similar to those of Embodiments 2 and 3 to drop off from the door 2 while reducing the area in which the double-sided tape 10 is used and reducing the cost. However, it is a condition that the adhesive force of the double-sided tape 10 exceeds the force of peeling the double-sided tape 10 caused by the deformation of the outer surface material 3 and the frame member 5 and the elongation of the base material of the double-sided tape 10.

  In addition, when a decorative film (not shown) is pasted on the entire surface of the glass 7 as a decoration of the glass 7, the double-sided tape 10 that bonds the outer surface material 3 and the frame member 5 is pasted on the decorative film; Become. The decorative film adhesive (not shown) used when the decorative film is attached to the glass 7 has an adhesive strength comparable to that of the adhesive 9 normally used for attaching the anti-scattering film 8. In this case, by making the tensile elongation of the base material of the double-sided tape 10 bonded to the second bonding region 14 higher than that used in Embodiment 3, the decorative film from the glass 7 The peeling load can be reduced. With such a configuration, it is possible to obtain a fixing strength and durability against an external force that causes the outer surface material 3 to fall off from the door 2. However, the adhesive force of the double-sided tape 10 and the adhesive force of the decorative film adhesive are different from the force of peeling the double-sided tape 10 and the decorative film caused by the deformation of the outer surface material 3 and the frame member 5 and the expansion of the double-sided tape 10. It must be exceeded.

  Moreover, when the scattering prevention film 8 is stuck on the entire surface of the glass 7, the tensile elongation of the base material of the double-sided tape 10 that adheres to the second adhesive region 14 is further increased than that used in the third embodiment. By making it high, the peeling load from the glass 7 of the scattering prevention film 8 can be reduced. With such a configuration, it is possible to obtain a fixing strength and durability against an external force that causes the outer surface material 3 to fall off from the door 2. However, the adhesive force of the double-sided tape 10 and the adhesive material 9 of the anti-scattering film 8 against the force to peel off the double-sided tape 10 and the anti-scattering film 8 caused by the deformation of the outer surface material 3 and the frame member 5 and the elongation of the double-sided tape 10. The condition is that the adhesive strength is higher.

  Further, the warpage of the door 2 itself when left at a low outside temperature immediately after filling the inside of the door 2 with a low outside temperature is 2.5 mm or less, and the force to peel off the double-sided tape 10 due to the deformation of the outer surface material 3 and the frame member 5 is provided. When the adhesive strength is smaller than that of the double-sided tape 10, the anti-scattering film 8 attached to the outer surface material 3 is removed as in the first embodiment to provide the second adhesive region 14. By adopting such a configuration, the glass 7 and the frame member 5 can be directly bonded, so that the bonding strength between the outer surface material 3 and the frame member 5 so as not to drop off from the door 2 can be obtained. Therefore, it is possible to obtain a fixing strength and durability against an external force that causes the outer surface material 3 to fall off from the door 2 without requiring an elastic bonding means.
