  As shown in FIGS. 8 and 9, a resin film 27 is attached to the inner surface of the glass plate 25 via an adhesive 26 so as to cope with the peeling caused by the colored layer. For example, a colored layer 28 made of a metallic pattern such as a hairline is formed. As a result, the glass plate 25 becomes a glass plate with a colored layer. In this embodiment, the resin film 27 is made of polyethylene terephthalate having high transparency and high mechanical strength, and the colored layer 28 is formed on the side opposite to the glass plate 25 in the white system and on the glass plate 25 side in the gray system. It is formed. In the drawing, the case where it is formed on the side opposite to the glass plate 25 is shown.

  In addition, when emphasizing the hairline three-dimensionally, a concave and convex groove is provided on the surface of the resin film opposite to the colored layer formed on the glass plate 25 side to form a three-dimensional hairline on the surface. A chromium deposition layer is formed. As a result, the design properties can be improved, and by using chromium as the material of the vapor deposition layer, the rust generation of the vapor deposition layer starting from the end surfaces of the film and the vapor deposition layer can be prevented, and the durability of the pattern is improved. .

  29 is a hard urethane filled and foamed in the space between the inner film 23 and the edge frame 24 on the surface of the glass plate 25 on the resin film 27 side, and the glass plate 25 together with the inner frame 23 and the edge frame 24 by foaming. The glass plate 25 is adhered to and held on the resin film 27 on the inner surface via the resin film 27.

Here, the edge frame 24 of the inner frame 23 does not have the colored glass plate insertion portion as described in the conventional example, and the glass plate 25 has a configuration in which the outer peripheral portion is exposed as it is. Furthermore, the glass plate 25 has a configuration in which the outer peripheral edge is positioned slightly inside the end face 24c of the edge frame 24 as shown in FIG.

  Further, as shown in FIG. 4, the grip portions 10 a and 10 a of the kannon doors 10 and 10 are configured by forming an upward concave portion on the lower end surface of the edge frame 24. Further, the handle portions 11a and 12a of the drawer type doors 11 and 12 directly below the kannon type doors 10 and 10 are configured by forming an upward concave portion on the lower end surface of the edge frame 24 of the drawer type doors 11 and 12. Further, the grip portions 13 a and 14 a of the freezer compartment 8 and the vegetable compartment 9 below are formed by forming downward concave portions on the upper end surfaces of the edge frames 24 of the pull-out doors 13 and 14, respectively. And the edge frame 24 which formed each said handle part 10a, 10a, 11a, 12a, 13a, 14a does not have a colored glass plate insertion part as already stated, but it protrudes from the front surface of the glass plate 25. There is no configuration.

  In this embodiment, the upper ends of the pull-out type doors 11 and 12 located directly below the kannon type doors 10 and 10 are inclined surfaces 11b and 12b that project from the upper side toward the lower side and are inclined. The structure is such that hand insertion into the handle portions 10a, 10a of the kannon door can be easily performed.

  Further, as is apparent from FIG. 5, the lower end a of the inclined surfaces 11b and 12b is higher than the upper end b of the glass plate 25 of the pull-out doors 11 and 12 provided with the inclined surfaces 11b and 12b. The upper end portion C of the inclined surfaces 11b and 12b is located on the far side of the depth of the depth of the doors 10 and 10 located above the inclined surfaces 11b and 12b.

  On the other hand, in this embodiment, a configuration for ensuring the adhesion and holding of the glass plate 25 which is concerned by eliminating the glass plate insertion portion that holds the outer peripheral portion of the glass plate 25 is provided, and the configuration will be described below. .

  First, the urethane foam 29 filled and foamed in the space between the surface of the glass plate 25 on the side of the resin film 27 and the inner frame 23 and the edge frame 24 has a foaming density of the outer peripheral portion from the central portion of the glass plate 25. Is set higher.

  Further, the edge frame 24 of the inner frame 23 and the outer peripheral portion of the glass plate 25 are bonded via a double-sided tape 30.

  Accordingly, the glass plate 25 is bonded and held to the urethane foam 29 and is also bonded and held to the edge frame 24 by the double-sided tape 30.

  As shown in FIG. 10, the double-sided tape 30 includes a horizontal tape portion 30a positioned along the upper and lower horizontal edges of the glass plate 25 and a vertical tape portion 30b positioned along the left and right edges of the glass plate 25. The horizontal tape portion 30a is affixed to the edge frame 24 in such a manner that the horizontal width of the glass plate 25 is located almost full and the short side surface of the vertical tape portion 30b is abutted against the long side surface. The tape bonding surface of the edge frame 24 includes a flat portion 24a located on the outer edge side of the edge frame, and a plurality of grooves 24b located on the inner edge side of the edge frame and opened to the inner edge side of the edge frame. The double-sided tape 30 is attached to the edge frame 24 so as to straddle both the flat portion 24a and the groove 24b.

  Furthermore, in this embodiment, as shown in FIG. 8, the portion located on the lower end surface of the glass plate 25 in the edge frame 24 of the inner frame 23 does not jump forward from the front surface of the glass plate 25. A transparent front plate support piece (hereinafter referred to as a glass plate support piece) 24d that is superposed on the lower end surface of the glass plate with a certain size is provided to support the weight of the glass plate 25.

In the above configuration, each door of the refrigerator has a front surface made of a glass plate 25 with a colored layer. Therefore, a depth is added to the color of the colored layer 28, the texture is increased, and the design is high. Moreover, even if there are a plurality of the doors, the glass plate 25 constituting the front surface of each of the heat insulating doors 10 to 14 has no protrusion due to the glass plate insertion portion or the handle portions 10a to 14a. Since it is a flat surface, the entire door surface is clean and good with a flat feeling.

  Moreover, since the drawer type doors 12 and 13 just under the kannon type doors 10 and 10 of the refrigerator compartment 5 located in the uppermost part in the refrigerator main body are formed with inclined surfaces 11b and 12b at their upper ends, the kannon type Hands can be easily inserted into the handle portions 10a, 10a of the doors 10, 10. In particular, in this embodiment, the upper end portions of the inclined surfaces 11b and 12b are positioned on the back side of the depth of the depth of the doors 10 and 10 positioned above the inclined surfaces 11b and 12b. Hand insertion into the handle portions 10a and 10a recessed in the lower end surfaces of the doors 10 and 10 can be easily performed without any obstacles.

  As a result, in this refrigerator, the gap between the Kannon doors 10 and 10 and the pull-out doors 11 and 12 immediately below the doors can be reduced. The gap between the kannon doors 10 and 10 and the pull-out doors 11 and 12 located immediately below the doors is relatively high and is easily noticeable by the user. However, the gap is narrow. Furthermore, it is possible to maintain a good sense of unity and flatness between the Kannon doors 10 and 10 and the drawer doors 11 and 12.

  In addition, the gap between the left and right doors of the kannon doors 10 and 10 can be narrowed by providing the handle portions 10a and 10a in the lower end surface of the door so that it is not necessary to provide a handle portion between the left and right doors. The sense of unity and flatness of the left and right doors of the kannon doors 10 and 10 can be maintained well.

  In this way, by maintaining the unity feeling and flatness between the doors 10 and 10 and the drawer doors 11 and 12 and the left and right doors of the doors 10 and 10, the design is further improved.

  Further, the end portions of the pull-out doors 11 and 12 below the inclined surfaces 11b and 12b are positioned above the upper edge of the transparent front plate 25 of the pull-out doors 11 and 12 provided with the inclined surfaces 11b and 12b. Therefore, even when the user opens and closes the doors 10 and 10 while holding the pan in his hand, the upper edge of the transparent front plate 25 is formed by the inclined surfaces 11b and 12b located above the upper edge. It is guarded by the lower end and can be prevented from being damaged. That is, even if the glass plate insertion portion for holding the glass plate 25 is abolished, the outer peripheral portion of the glass plate can be prevented from being damaged and can be used with confidence.

  Further, in this embodiment, since the outer peripheral edge of the glass plate 25 is positioned slightly inside the end surface 24c of the edge frame 24, the glass plate 25 has not only the upper end portion but also the entire outer peripheral edge thereof. The end face 24c of this will protect. Therefore, for example, it is possible to prevent the outer peripheral edge of the glass plate 25 from hitting a certain object and cracking at the time of door transportation on the production line or door replacement service at the user's house.

  On the other hand, the refrigerator door is configured such that the foam density of the urethane foam 29 is higher in the outer peripheral portion than in the central portion of the glass plate 25, and therefore the adhesive force of the foamed urethane 29 is higher in the outer peripheral portion of the glass plate 25. Become stronger. Thereby, the adhesive force between the resin film 27 of the glass plate 25 and the urethane foam 29 can be more reliably maintained and secured over a long period of time.

That is, the outer peripheral portion of the foamed urethane 29 has a high foaming density, in other words, a skin layer that is very finely foamed, and therefore has a large adhesion area, and as a result, the resin film of the foamed urethane 29 and the glass plate 25. The adhesion density with 27 is high and strong. Therefore, even if the glass plate insertion portion is abolished, the glass plate 25 can be securely bonded to the urethane foam 29 over a long period of time.

  Further, the door holds the glass plate 25 with the urethane foam 29 and at the same time, the outer peripheral portion of the glass plate 25 is bonded to the edge frame 24 of the inner frame 23 with the double-faced tape 30. In addition to bonding to the edge frame 24, the double-sided tape 30 is used. Therefore, the glass plate 25 with the colored layer to which the resin film 27 is attached is strongly bonded and held to both the urethane foam 29 and the edge frame 24, and the adhesive strength of the glass plate 25 is maintained over a long period of time. Can be ensured.

  In addition, since the double-sided tape 30 has the outer peripheral portion of the glass plate 25 bonded to the edge frame 24 of the inner frame 23, the water applied to the door enters the door inward from the door end and foams due to this water intrusion. The adhesion peeling between the urethane 29 and the glass plate 25 can be reliably prevented, and the adhesion and holding of the glass plate 25 can be ensured for a long period of time.

  That is, the refrigerator has a large temperature difference between the inside and the outside, and the end of the glass plate 25 of the door is affected by condensation and severe temperature changes due to the cold air from the inside when the door is opened and closed. Further, depending on the usage of the user, the door may be subjected to a severe impact during opening and closing, or the door including the glass plate 25 may overflow with water or juice when the stored items are put in and out. And if there is no glass plate insertion part which covers the said glass plate edge part by the use environment and the actual condition peculiar to such a refrigerator, the water etc. which hung on the door edge part will infiltrate into the door inside. It is easy to peel off from the urethane foam 29.

  Under such circumstances, in this embodiment, the glass plate 25 serving as the door end portion and the edge frame 24 of the inner frame 23 are bonded by the double-sided tape 30, so that the glass plate 25 and the edge frame are bonded. The double-sided tape 30 can reliably prevent water and the like from entering between 24 and the inside of the door. Therefore, water or the like can enter the door inward from the edge of the door to prevent the adhesive peeling between the glass plate 25 and the urethane foam 29 and maintain the adhesive strength between the glass plate 25 and the urethane foam 29 over a long period of time. can do.

  In particular, the double-sided tape 30 has a configuration in which the short side surface of the vertical tape portion 30b is abutted against the long side surface of the horizontal tape portion 30a disposed along the upper and lower horizontal edges of the glass plate 25. Since the horizontal top part 30a of the double-sided tape 30 is located without any break across the entire length of the door upper part, which is likely to enter inward due to gravity, even if water is splashed on the part. Water can be reliably prevented from entering the glass, and the reliability of the adhesion and holding of the glass plate 25 can be further enhanced.

  The tape bonding surface of the edge frame 24 of the inner frame 23 includes a flat portion 24a located on the outer edge side of the edge frame and a plurality of grooves 24b located on the inner edge side of the edge frame and opened to the inner edge side of the edge frame. Therefore, when the double-sided tape 30 is affixed to the edge frame 24 of the inner frame 23, bubbles that are likely to be generated between the double-sided tape 30 and the edge frame 24 are smoothly removed from the plurality of grooves 24b. Adhesion of the reliable double-sided tape 30 becomes possible, and the adhesive strength of the glass plate 25 can be further improved.

  The adhesive force between the glass plate 25 and the foamed urethane 29 is the result of an accelerated life test. As a result, the adhesive force is 1.0 g / cm 2 or more, preferably 2.6 g / cm 2 or more. The adhesive strength between the resin film 27 and the urethane foam 29 can be reliably ensured even if the adhesive strength is deteriorated due to secular change such as shrinkage, and as a result, the adhesive strength of the glass plate 25 is maintained and guaranteed over a long period of time. It was possible to make it highly reliable.

The method for measuring the adhesive force is based on “JIS K 6850 (Adhesive—Tensile Shear Adhesive Tensile Shear Adhesive Strength Test Method)”, which is a standard method for measuring the overlapping shear adhesive strength of an adhesive.

  On the other hand, in the refrigerator of this embodiment, since the colored layer 28 is formed on the resin film 27, the colored layer 28 can be formed by a roller or the like. As a result, a fine pattern such as a hairline that could not be obtained substantially can be formed, and the design can be remarkably improved.

  In addition, since the glass plate insertion portion has been abolished, dust and dust adhere to and accumulate on the boundary between the glass plate insertion portion and the glass plate, and this does not stand out linearly over time, The initial high designability can be maintained as it is over a long period of time.

  In addition, since the colored layer 28 can be formed by a roller or the like, the adhesive strength to the resin film 27 can be managed and ensured even if the adhesive state deteriorates due to thermal shrinkage or aging of urethane foam. 27 can be reliably prevented from being peeled off.

  As a result, when the resin film 27 is positioned between the glass plate 25 and the foamed urethane 29 and both are adhered by the adhesive force of the foamed urethane 29 and the adhesive 26, the colored layer 28 is peeled off from the resin film 27. It is also possible to prevent the glass plate 25 from being peeled off from the urethane foam 29 due to peeling. Therefore, it is possible to maintain and ensure the adhesive strength of the glass plate with film 25 for a longer period of time.

  Even if some external force is applied to the glass plate 25 and it should break, this glass plate piece is adhered to the resin film 27 to prevent scattering, and safety in the event of an emergency is also improved. To do.

  Furthermore, in this embodiment, a portion of the edge frame 24 of the inner frame 23 positioned on the lower end surface of the glass plate 25 is superposed on the lower end surface of the glass plate without jumping forward from the front surface of the glass plate 25. Since the plate support piece 24 d is positioned, the glass plate 25 is supported by the glass plate support piece 24 d of the edge frame 24 of the inner frame 23. Therefore, even if the peeling of the glass plate 25 may partially occur due to the deterioration of the adhesive force of the glass plate 25 by the urethane foam 29, an abnormal situation such as the dropping of the glass plate 25 is surely prevented. This will greatly improve your sense of security. Further, since the glass plate support piece 24d of the edge frame 24 does not protrude from the front surface of the glass plate, it is not visible from the front surface of the door as in the glass plate insertion portion, and the design and the flat feeling of the entire surface can be maintained. .

  As mentioned above, although main embodiment of this invention was described, the said embodiment was shown as an example in implementing this invention, and can be variously changed within the range which achieves the objective of this invention. Needless to say.

  For example, the glass plate may be replaced with a transparent resin plate, which makes it possible to further secure the adhesive strength by reducing the weight and to reduce the cost. Moreover, although the resin film with a colored layer was stuck on the glass plate and it was set as the glass plate with the colored layer, this abolished the resin film and formed a colored layer directly on the glass plate as a glass plate with a colored layer. Is also good.

Further, the colored layer 28 of the resin film 27 may be on the glass plate side as described above, and in order to improve the adhesive strength between the resin film 27 and the urethane foam 29, An easy-adhesion layer may be formed by performing corona treatment or plasma treatment, or applying urethane, polyester, or acrylic adhesive. Further, a urethane binder or a vapor deposition layer may be used as the easy adhesion layer, or a vapor deposition layer and / or a urethane binder may be further interposed between the easy adhesion layer and the urethane foam 29, as necessary. By using it, the adhesive strength and the design of the colored layer can be improved.

  As described above, the present invention can be a refrigerator having a high-design door with a flat overall surface without protruding even if the refrigerator door has a texture and is constituted by a plurality of heat insulating doors. Of course, it can be widely applied to commercial refrigerators and wine coolers.
