  Next, the configuration of the refrigerator door right door 10b will be described in detail with reference to FIGS. 4 to 7. FIG.

  4 to 7, the inner frame 23 to be positioned inside the refrigerator main body 1 is made of, for example, ABS resin. The edge frame 24 bonded and fixed to the peripheral end surface of the inner frame 23 is made of ABS resin. A transparent front plate 25 (hereinafter referred to as a glass plate 25) such as a glass plate laminated on the edge frame 24 so as to cover the inner frame 23 is a glossy tempered glass plate or a tempering treatment in the present embodiment. A glass plate is used.

  On the back surface (the inner frame 23 side) of the glass plate 25, for example, a colored layer 28 made of a metallic pattern such as a hairline is provided. The colored layer 28 may be a coating method formed by painting on the back surface of the glass plate 25, or may be a resin film method in which a resin film provided with a picture pattern is attached via an adhesive.

  The peripheral edge of the glass plate 25 is bonded and held by an adhesive, for example, a double-sided tape 26, provided on the flange 30 of the edge frame 24.

The hard urethane 29 filled and foamed in the space between the inner layer 23 and the edge frame 24 and the surface on the colored layer 28 side of the glass plate 25 is foamed together with the inner frame 23 and the edge frame 24 to form the glass plate 25. It adheres to the colored layer 28 on the inner surface, and the glass plate 25 is adhered and held via urethane 29.

  That is, the glass plate 25 is bonded and held by both the double-sided tape 26 and the urethane 29.

  Note that the glass plate 25 is not necessarily bonded to the urethane 29, and may be any specification as long as the glass plate 25 is fixed to the inner frame 23.

  Here, as shown in FIG. 7, the edge frame 24 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 a part of the outer peripheral portion is exposed as it is. is there.

  Specifically, the outer peripheral side surface 25a of the glass plate 25 is arranged to face the edge frame front end portion 24a protruding forward from the flange portion 30 of the edge frame 24, and a part of the outer peripheral side surface 25a of the glass plate 25 is exposed. It is set as the arrangement arranged.

  Therefore, the outer peripheral side surface 25 a of the glass plate 25 is disposed so as to be partially exposed, and is disposed on the inner side of the edge frame side surface 24 c of the edge frame 24.

  A C surface 27 is formed on at least a part of the outer peripheral portion of the glass plate 25. The width dimension W1 of the C surface 27 is set larger than the plate thickness dimension T1 of the glass plate 25. In the present embodiment, the thickness T1 of the glass plate 25 is 3.2 mm, and the width W1 of the C surface 27 is 14 mm.

  Further, assuming that the plate thickness dimension of the end portion (outer peripheral portion) of the C surface 27 of the glass plate 25 is T2, T2 secures a plate thickness more than half of T1 (T2> T1 / 2). In this embodiment, T2 = 1.7 mm.

  Moreover, the part connected from the edge part of the C surface 27 of the glass plate 25 to the outer peripheral side surface 25a forms the R part 25b which is a curved surface for end surface protection.

  Further, an edge frame inclined surface 24 b is formed from the edge frame front end portion 24 a of the edge frame 24 to the side surface portion of the edge frame 24.

  And the front-end part of the outer peripheral side surface 25a of the glass plate 25 is located so that it may not protrude ahead from the front extension surface of the edge frame inclined surface 24b.

  Further, the inner end portion of the flange portion 30 of the edge frame 24 is located on the inner side (center side) than the C surface inner end portion 27 b of the C surface 27 of the glass plate 25. That is, the width W2 of the flange portion 30 is set larger than the width W1 of the C surface 27.

  Further, in order to increase the strength of the edge frame 24, a U-shaped reinforcing member 33 is disposed between the second flange portion 31 and the third flange portion 32 provided continuously on the inner surface of the edge frame 24. ing.

  And in the double-folding type refrigerator compartment left door 10a, the C surface 27 is formed in the peripheral part of the upper side and the left side. In the double door type refrigerator compartment right door 10b, the C surface 27 is formed on the upper and right peripheral edges. In the ice making chamber door 11, a C surface 27 is formed on the left peripheral portion. In the switching chamber door 12, a C surface 27 is formed on the right peripheral edge. In the freezer compartment door 13 and the vegetable compartment door 14, the C surface 27 is formed in the peripheral part of the left side and the right side.

That is, in the front view of the entire refrigerator in FIG. 3, the C surface 27 is formed across the plurality of doors at the left, right and upper peripheral portions of the refrigerator provided with a plurality of doors on the top, bottom, left and right.

  In addition, about the arrangement | positioning of the outer peripheral side surface which does not form C surface 27 of the glass plate 25 of each door, and the edge frame 24, the outer peripheral side surface of the glass plate 25 is only a part by the difference in the presence or absence of the C surface 27. It is arranged so as to be exposed, and is located inside the edge frame side surface 24 c of the edge frame 24.

  Moreover, the upper part of each drawer-type door of the freezer compartment door 13 and the vegetable compartment door 14 is formed as a handle for pulling the door forward, and a concave portion is formed downward on the upper side of the edge frame 24. The width of the rising portion at the left and right end portions of the concave portion of the edge frame 24 is substantially the same as the width W1 of the C surface 27 formed at the left and right peripheral edge portions of the glass plate 25.

  Further, a lower portion of each drawer type door of the ice making chamber door 11 and the switching chamber door 12 is formed as a handle for pulling the door forward, and a concave portion is formed upward on the lower side of the edge frame 24.

  With the above configuration, the glass plate 25 of the refrigerator compartment right door 10b is firmly bonded and held by both the double-faced tape 26 provided on the flange portion 30 of the edge frame 24 and the urethane 29 filled and foamed.

  Further, the edge frame 24 does not have the colored glass plate insertion portion as described in the conventional example, and the outer peripheral side surface 25a of the glass plate 25 protrudes forward from the flange portion 30 of the edge frame 24. 24a is arranged opposite to the outer peripheral side surface 25a of the glass plate 25 so that a part of the outer peripheral side surface 25a is exposed. Since it is located on the inner side of the edge frame side surface 24c of the edge frame 24, it does not impair the design like a conventional glass plate insertion part, and it has a clean appearance with a flat feeling on the entire surface. can do. In addition, dust or dust adheres and accumulates at the boundary between the glass plate insertion portion and the glass plate, and this does not stand out linearly, maintaining the initial high design as it is for a long period of time. be able to.

  Further, since the C surface 27 is formed on at least a part of the outer peripheral portion of the glass plate 25, the glass plate 25 provides a high-class feeling like crystal cut glass and provides a refrigerator having a door with high design. can do.

  Moreover, since the width dimension W1 of the C surface 27 is set larger than the plate thickness dimension T1 of the glass plate 25, the presence of the C surface 27 can be sufficiently secured while maintaining a balance between quality and cost. It is possible to provide a door with high design, in which the plate 25 has a high-class feeling like crystal cut glass.

  Here, the width W1 of the C surface 27 has an appropriate dimension. The reason is that the C surface 27 is formed by mechanically cutting the end portion of the flat glass plate 25. Therefore, if the C surface 27 having a predetermined dimension or more is formed, the angle of the cutting portion becomes loose, and the manufacturing is performed. Due to the above variation, the boundary between the flat portion of the glass plate 25 and the C surface 27 may be undulated and the linearity cannot be ensured. On the other hand, when the C surface 27 having a predetermined dimension or less is formed, the presence of the C surface 27 cannot be expressed, and the design appeal is impaired. In this embodiment, W1 is set to 14 mm from the balance of quality and cost, but W1 is preferably not less than the plate thickness T1 of the glass plate 25 and not more than 8 times the plate thickness T1. Further, the angle of the C surface 27 is desirably 5 degrees or more with respect to the flat surface.

  Further, since the plate thickness T2 of the end portion (outer peripheral portion) of the C surface 27 of the glass plate 25 is more than half the thickness of T1 with respect to the plate thickness T1 of the glass plate 25, the end portion of the C surface 27 Problems such as the strength of the (outer peripheral portion) and cracks can be prevented.

Moreover, since the part connected to the outer peripheral side surface 25a from the edge part of the C surface 27 of the glass plate 25 forms the R part 25b which is a curved surface for end surface protection, the strength of the C surface 27 end part (outer peripheral part), Problems such as cracks can be prevented.

  Further, since the edge frame inclined surface 24b is formed from the edge frame front end portion 24a of the edge frame 24 to the side surface portion of the edge frame 24, the sense of unity with the C surface inclined surface 27a forming the C surface 27 is enhanced. Furthermore, the design of the door surface can be enhanced. Moreover, since the refrigerator compartment right door 10b is a hinged rotary door and has an edge frame inclined surface 24b formed on the rotary shaft side, the gap between the refrigerator main body and the edge frame 24 can be kept wide when the door is opened and closed. it can. Therefore, the safety of the user can be improved.

  Further, since the front end portion of the outer peripheral side surface 25a of the glass plate 25 is positioned so as not to protrude forward from the front extension surface of the edge frame inclined surface 24b, even if an object contacts the edge frame from the outside, the glass The opportunity for an object to contact the front end portion of the outer peripheral side surface 25a of the plate 25 can be reduced, and problems such as strength and cracking at the end portion (outer peripheral portion) of the C surface 27 can be prevented.

  Moreover, the inner side edge part of the flange part 30 of the edge frame 24 is located inside (center part side) from the C surface inner side edge part 27b of the C surface 27 of the glass plate 25, that is, the width W1 of the C surface 27. Since the width W2 of the flange portion 30 is set to be larger, the gap between the receiving surface on the glass plate 25 side of the urethane jig (flat surface of the glass plate 25) and the flange portion 30 when the urethane 29 is filled and foamed. There is no gap (space), and deformation of the flange portion 30 due to pressure during filling and foaming hardly occurs. Therefore, defects due to deformation of the flange portion 30, for example, generation of residual stress strain in the glass plate 25, decrease in adhesive strength between the glass plate 25 and the urethane 29 due to urethane shrinkage after urethane filling foaming (ease of peeling), or Moreover, the fall (ease of peeling) of the adhesive strength of the glass plate 25 and the double-sided tape 26 can be reduced.

  Further, in order to increase the strength of the edge frame 24, a U-shaped reinforcing member 33 is disposed between the second flange portion 31 and the third flange portion 32 provided continuously on the inner surface of the edge frame 24. Therefore, deformation of the edge frame 24 can be prevented, and the quality of the door body after urethane filling and foaming can be improved.

  In addition, since the C surface 27 is formed across the plurality of doors at the left, right and upper peripheral portions of the refrigerator main body 1 provided with a plurality of doors on the top, bottom, left and right, the total design of the outer peripheral portion of the entire refrigerator Can be improved.

  In other words, since the C surface 27 is not provided on the opposing surfaces of the refrigerator compartment left door 10a and the refrigerator compartment right door 10b, which are double-split heat insulating doors, the sense of unity of the double-spread door is improved. Similarly, since the C surface 27 is not provided on the adjacent surfaces of the ice making chamber door 11 and the switching chamber door 12, the sense of unity between the doors adjacent to the left and right is improved.

  Moreover, about the arrangement | positioning of the outer peripheral side surface which does not form the C surface 27 of the glass plate 25 of each door, and the edge frame 24, only the difference of the presence or absence of the C surface 27, the outer peripheral side surface of the glass plate 25 partially Since it is arranged so as to be exposed and located on the inner side of the edge frame side surface 24c of the edge frame 24, it can be made a clean appearance with a flat feeling on the entire surface in all doors, and can be made of glass. Dust and dust adhere to and accumulate on the boundary between the plate insertion portion and the glass plate, and this does not stand out linearly, and the initial high design can be maintained as it is for a long period of time. .

  In addition, the freezer compartment door 13 and the vegetable compartment door 14 are formed with C-faces 27 on the left and right peripheral edges, so that the handle portions formed on the upper part of each pull-out door of the freezer compartment door 13 and the vegetable compartment door 14 There is no C surface at the peripheral edge of the glass plate 25 adjacent to. Therefore, the relative strength reduction of the glass plate 25 due to the C-plane formation can be prevented, and the relative safety of the user can be improved.

  Moreover, since the C surface 27 is formed in the peripheral part of the left side and the right side in the freezer compartment door 13 and the vegetable compartment door 14, the lower periphery of the glass plate 25 of each drawer-type door of the freezer compartment door 13 and the vegetable compartment door 14 The part has no C-plane. Therefore, the relative strength reduction of the glass plate 25 due to the C-plane formation of the lower peripheral edge receiving the load of the glass plate 25 can be prevented, and the reliability of the freezer compartment door 13 and the vegetable compartment door 14 is relatively enhanced. Can do.

  In the present embodiment, the C surface 27 is formed across the plurality of doors at the left and right sides and the upper peripheral edge of the refrigerator main body 1 provided with a plurality of doors in the upper, lower, left and right directions. The C surface 27 may be formed over the entire circumference. In this case, the glass plate 25 has a high-class feeling like crystal cut glass for all doors, and can provide a door with high design.

  Moreover, you may form the C surface 27 straddling a some door only in the peripheral part of the left side and the right side of the refrigerator main body 1 provided with the some door up and down and right and left. In this case, the crystal cut glass feeling on both side surfaces of the integrated refrigerator can be emphasized, and a refrigerator with high designability can be provided.
