Description

[Technical field]

[0001] The present invention relates to a refrigerator for refrigerating and / or freezing food and beverages. [Background technology]

[0002] In recent refrigerators, glass plates are arranged on the design surface facing the outside of insulated doors such as pivoting doors (double doors) and drawer doors to enhance the design. In addition, a configuration is adopted in which a vacuum insulation material containing inorganic fibers such as glass fibers is arranged on the back surface of the glass plate as an insulation material provided on the insulated door.

[0003] For example, JP 2014-52157 A (Patent Document 1) shows an insulated door comprising a glass plate on the outer surface, a door frame on the periphery of the glass plate, and a vacuum insulation material placed on the back surface of the glass plate, with the outer peripheral edge of the back side of the glass plate and the door frame adhered together using double-sided adhesive tape. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-52157 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in a refrigerator as disclosed in Patent Document 1, the door frame and the outer periphery of the four sides of the glass plate are bonded with double-sided adhesive tape. The double-sided adhesive tape is attached by butting the long sides of the horizontal tape portion and the long sides of the vertical tape portion against each other. When using such a method of attaching the double-sided adhesive tape, it is important to accurately manage the attachment position of the double-sided adhesive tape.

[0006] For example, depending on the work of a worker or a work robot, the long side end of the horizontal tape section and the long side end of the vertical tape section may overlap each other. The thickness of the double-sided adhesive tape is laminated at the overlapping portion, making it thicker. This causes the glass plate placed on the double-sided adhesive tape to float at the laminated portion, adversely affecting the external design. In addition, since the adhesive strength is reduced only at the floating portion of the glass plate, air leakage may occur in the vacuum insulation material stored in the insulated door, and if a restoring force is generated in the core material, the glass plate may peel off from the door frame.

[0007] Furthermore, if the end of the long side of the horizontal tape section or the end of the long side of the vertical tape section is attached at a position beyond the correct position, the end face of the double-sided adhesive tape in the excess portion will be visible through the glass plate, resulting in an unsightly appearance and potentially making it impossible to ship the product.

[0008] An object of the present invention is to provide a refrigerator capable of accurately managing the attachment position of a double-sided adhesive tape when the double-sided adhesive tape is attached. [Means for solving the problem]

[0009] The present invention relates to a refrigerator having a refrigerator compartment and / or a freezer compartment and an insulated door provided in each of the refrigerator compartment and / or the freezer compartment, wherein the insulated door at least has a rectangular outer panel provided on its outer surface and a rectangular frame-shaped door frame provided on the outer peripheral edge of the outer panel, and at least one side of the door frame is bonded to the outer peripheral edge of the back side of the outer panel using double-sided adhesive tape, and a positioning marker is formed in the area of ​​the door frame where the double-sided adhesive tape is attached, for determining the position of the tip of the double-sided adhesive tape in the attachment direction of the double-sided adhesive tape. Effect of the Invention

[0010] According to the present invention, when applying the double-sided adhesive tape, the application position of the double-sided adhesive tape can be accurately controlled by the positioning marker. [Brief description of the drawings]

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiment, and various modifications and application examples within the technical concept of the present invention are also included within its scope.

[0013] First, the configuration of a refrigerator to which the present invention is applied will be described. Fig. 1 is a perspective view of a refrigerator 100 according to an embodiment of the present invention. Fig. 2 is a front view of the refrigerator 100 shown in Fig. 1.

[0014] As shown in Figs. 1 and 2, a refrigerator 100 according to an embodiment of the present invention includes a box body 20 and an insulated door 10 attached to the box body 20. In this embodiment, the insulated door 10 is composed of a plurality of insulated doors 1 to 6. That is, the insulated door 10 is used as a general term for the insulated doors 1 to 6. An outer box 21 includes a top panel 22, a back panel (see Fig. 3), a bottom panel (see Fig. 3), a left side panel (not shown), and a right side panel 25. The insulated doors 1 and 2 are supported by hinges 36 so as to be freely rotatable.

[0015] Fig. 3 is a cross-sectional view showing the AA cross section of the refrigerator shown in Fig. 2. As shown in Fig. 3, refrigerator 100 has, from the top, a refrigeration compartment 11, an ice-making compartment 12, an upper freezer compartment 13, a lower freezer compartment 14, and a vegetable compartment 15 as storage compartments. Insulated doors 1 to 6 are doors for opening and closing openings formed in the front of each storage compartment.

[0016] 2 and 3, the insulating doors 1 and 2 are pivotable insulating doors that pivot about hinges 36, and the insulating doors 3 to 6 are drawer-type insulating doors. When the drawer-type insulating doors 3 to 6 are drawn out, the containers that constitute the respective chambers are drawn out together with the insulating doors.

[0017] The insulating doors 1 and 2 are for the refrigerator compartment 11, the insulating door 3 is for the ice-making compartment 12, the insulating door 4 is for the upper freezer compartment 13, the insulating door 5 is for the lower freezer compartment 14, and the insulating door 6 is for the vegetable compartment 15. The insulating doors 1 and 2 are pivoting doors, and the insulating doors 3 to 6 are drawer-type doors. Each of the insulating doors 1 to 6 is provided with a packing 37 (see FIG. 3) for sealing the refrigerator 100. The packing 37 is attached to the outer periphery of each of the insulating doors 1 to 6 on the interior side.

[0018] As shown in Fig. 3, each of the insulating doors 1 to 6 has a design surface portion 31 facing the outside and an inner wall portion 32 facing the inside of the room. In this embodiment, inside each of the insulating doors 1 to 6, i.e., between the design surface portion 31 and the inner wall portion 32, a vacuum insulating material 50 is arranged as an insulating material, which includes a core material made of inorganic fibers (e.g., glass fiber) and an outer packaging material that covers the core material, and the inside is decompressed by drawing a vacuum.

[0019] Furthermore, the space inside each of the insulating doors 1 to 6 other than the vacuum insulating material 50 is filled with a foam insulating material 33 such as a hard urethane foam.

[0020] Further, a partitioning heat insulating wall 16 is provided to separate and insulate the refrigerator compartment 11 from the ice making compartment 12 and the upper freezer compartment 13. Because the temperature zones between the ice making compartment 12, the upper freezer compartment 13 and the lower freezer compartment 14 are the same, a partitioning heat insulating wall is not provided to separate and insulate the compartments, but a partitioning member 17 that forms a receiving surface for a packing 37 is provided.

[0021] A partition wall 18 for insulating the compartments is provided between the lower freezer compartment 14 and the vegetable compartment 15. The arrangement of the storage compartments in the box 20 is not particularly limited to the arrangement described above. In addition, the insulating doors 1 to 6 are not particularly limited in whether they are opened or closed by pivoting or by pulling out, and in the number of divisions of the insulating doors.

[0022] The box 20 comprises an outer box 21 made of steel plate and an inner box 27 made of synthetic resin, and an insulating layer is provided in the space formed by the outer box 21 and the inner box 27 to insulate each storage chamber in the box 20 from the outside. The outer box 21 comprises a top panel 22, a back panel 23, a bottom panel 24, a left side panel (not shown), and a right side panel 25 (see FIG. 1).

[0023] A vacuum insulation material 50 is placed in the space between the outer box 21 and the inner box 27, and the space other than the vacuum insulation material 50 is filled with a foam insulation material 34 such as rigid urethane foam. The partition insulation walls 16, 18 are composed of expanded polystyrene 35 and the vacuum insulation material 50, but are not limited to this and may be filled with a foam insulation material such as rigid urethane foam.

[0024] A cooler 44 for cooling each storage compartment of the refrigerator 100 to a predetermined temperature is provided on the rear side of the lower freezer compartment 14. This cooler 44, a compressor 45, a condenser 46, and a capillary tube (not shown) are connected to form a refrigeration cycle. A blower 43 is provided above the cooler 44 to circulate the cold air cooled by the cooler 44 inside the refrigerator 100 to maintain a predetermined low temperature.

[0025] A recess 40 for storing electric components 41 such as a board for controlling the operation of the refrigerator 100 and a power board is formed at the rear part of the top panel 22 of the box body 20, and a cover 42 for covering the electric components 41 is provided. The height of the cover 42 is set to be approximately the same height as the top surface of the outer box 21, taking into consideration the external design and securing the internal volume.

[0026] Next, a general configuration between the design surface portion 31 and the vacuum insulation material 50 in the insulated door will be briefly described with reference to Fig. 4. The cross section of the insulated door shown in Fig. 4 shows a transverse section of a pivoting insulated door 2 that opens and closes the refrigerator compartment 11 (a cross section viewed from the arrow BB in Fig. 3, a cross section perpendicular to the direction of gravity).

[0027] In Figure 4, the insulated door 2 is configured to include a rectangular outer panel (hereinafter referred to as glass plate) 60, for example made of glass, provided on the surface of the decorative surface of the insulated door 2, a door frame 61 (each composed of four frame members corresponding to each side of the glass plate) provided on the outer periphery of the glass plate 60, a vacuum insulation material 50 arranged on the back surface of the glass plate 60, a foam insulation material 33 (see Figure 3) filled into a storage space surrounded on the front and sides by the glass plate 60 and the door frame 61, with the vacuum insulation material 50 interposed therebetween, and an inner wall portion (not shown, see Figure 3) provided on the back surface (rear surface) of the door frame 61 and covering the rear of the storage space.

[0028] The door frame 61 is formed from, for example, ABS (acrylonitrile butadiene styrene copolymer) resin or PP (polypropylene) resin.

[0029] The vacuum insulation material 50 is not particularly limited in material, but as an example, it is made of a heat insulating material in which a core material such as glass fiber is vacuum-packed in a laminate film and the inside is reduced in pressure and sealed, and has excellent heat insulating properties. The vacuum insulation material 50 is formed in a flat plate shape and is adhered to the back side of the glass plate 60.

[0030] The glass plate 60 is made of a rectangular flat glass plate that forms the outer wall (outer shell, design surface) on the front surface (front face) side of the insulated door 2. The outer peripheral edge of the glass plate 60 is attached to the inner front end of a rectangular door frame 61 that is long along the sides of the glass plate 60, and is surrounded by the door frame 61. The door frame 61 is made up of four frame members (upper, lower, left, and right frame members), which are combined to form the door frame 61.

[0031] In addition, the glass plate 60 is preferably a flat plate material made of reinforced glass, but a flat plate material such as plastic or ceramic may be used instead of glass. Therefore, the term "outer plate" may be used instead of glass plate.

[0032] Although not shown, a paint layer is provided on the rear surface of the glass plate 60, and a shatterproof film is provided on the rear surface of the paint layer.

[0033] The door frame 61 is formed with a plate-shaped main body portion 62 extending toward the inner wall portion 32 (see FIG. 3), and a flange portion 63 extending from the main body portion 62 substantially parallel to the surface of the glass plate 60 and substantially perpendicular to the main body portion 62. The flange portion 63 is located at substantially the end of the front side (glass plate side) of the door frame 61. A double-sided adhesive tape 64 is interposed between the flange portion 63 and the outer periphery of the glass plate 60, and the flange portion 63 and the glass plate 60 are firmly bonded together by this double-sided adhesive tape 64.

[0034] In a refrigerator having such a configuration, as described above, there is a risk that the long side end of the horizontal tape portion and the long side end of the vertical tape portion are attached to overlap each other. In the overlapping portion, the thickness of the double-sided adhesive tape is increased, and the glass plate is lifted at the laminated portion, which adversely affects the external design. In addition, if the adhesive strength is reduced only at the lifted portion of the glass plate, and an air leak occurs in the vacuum insulation material stored in the insulation door, a restoring force is generated in the core material, which may cause the glass plate to peel off from the door frame.

[0035] Furthermore, if the end of the long side of the horizontal tape section or the end of the long side of the vertical tape section is affixed at a position beyond the correct position, the excess portion of the double-sided adhesive tape will be visible through the glass plate, resulting in an unattractive appearance.

[0036] In order to solve such problems, the present invention proposes a configuration that allows accurate management of the application position of the double-sided adhesive tape when applying the double-sided adhesive tape. EXAMPLES

[0037] The first embodiment of the present invention aims to prevent the leading end of the horizontal tape portion in the long side direction and the leading end of the vertical tape portion in the long side direction from being attached in an overlapping state.

[0038] Its features include at least a rectangular exterior panel provided on the outer surface and a rectangular door frame provided on the outer peripheral edge of the exterior panel, with at least two adjacent sides of the door frame being adhered to the outer peripheral edge on the back side of the exterior panel using double-sided adhesive tape, and positioning markers are formed in the area of ​​the door frame where the double-sided adhesive tape is attached to determine the position of the tips of the double-sided adhesive tape on the two sides in the application direction of the double-sided adhesive tape.

[0039] 5 to 9 are diagrams for explaining the positioning markers to be formed on the insulation door 2 on the right side of the refrigerator compartment 11. This positioning marker has a function of determining the attachment positions of the tip of a horizontal tape portion (described later) and the tip of an adjacent vertical tape portion (described later).

[0040] Fig. 5 shows the front of the insulated door 2, and almost the entire outer surface of the insulated door 2 is covered with a glass plate 60. Fig. 6 shows the front of the insulated door 2 with the glass plate 60 removed, and the rectangular door frame 61 is formed from an upper frame member 61u on the upper side, a lower frame member 61b on the lower side, a left frame member 61l on the left side, and a right frame member 61r on the right side when viewed from the front.

[0041] A flange portion 63 (see Figure 4) is formed in each of the frame members 61u, 61b, 61l, and 61r, and on the surface of this flange portion 63 facing the glass plate 60, an upper double-sided adhesive tape 64u on the upper side, a lower double-sided adhesive tape 64b on the lower side, a left double-sided adhesive tape 64l on the left side, and a right double-sided adhesive tape 64r on the right side are affixed in a front view corresponding to each of the frame members 61u, 61b, 61l, and 61r.

[0042] That is, the door frame 61 is made up of a combination of frame members 61u, 61b, 61l, and 61r, and further, the "attachment areas" of the double-sided adhesive tapes 64u, 64b, 64l, and 64r are formed by a combination of flange portions 63u, 63b, 63l, and 63r formed on the frame members 61u, 61b, 61l, and 61r. That is, a rectangular frame-shaped tape attachment area is formed on the door frame 61, and the double-sided adhesive tapes 64u, 64b, 64l, and 64r are attached to the tape attachment area as shown in FIG.

[0043] When the refrigerator is placed on the floor of a house and in an upright position, the upper double-sided adhesive tape 64u and the lower double-sided adhesive tape 64b are arranged to extend in a direction perpendicular to the direction of gravity (approximately horizontal direction), and therefore may be described as "upper horizontal tape portion 64u" and "lower horizontal tape portion 64b." Similarly, the left double-sided adhesive tape 64l and the right double-sided adhesive tape 64r are arranged to extend in the direction of gravity, and therefore may be described as "left vertical tape portion 64l" and "right vertical tape portion 64r."

[0044] In this embodiment, as shown in part P, positioning markers, which are a feature of this embodiment, are formed near the respective tips of the lower horizontal tape part 64b and the right vertical tape part 64r, which are arranged at the corners of the butt joints of the right frame member 61r and the lower frame member 61b. Note that details of part P are shown enlarged in Figure 7, so part P will be described with reference to Figure 7.

[0045] Of course, positioning markers may be formed as many times as necessary near the leading ends of the remaining upper horizontal tape portion 64u and left vertical tape portion 64l, near the leading ends of the lower horizontal tape portion 64b and left vertical tape portion 64l, and near the leading ends of the upper horizontal tape portion 64u and right vertical tape portion 64R. In other words, positioning markers may be provided at all corners or at specific corners.

[0046] Next, details of part P will be described with reference to Fig. 7 to Fig. 9. Fig. 7 shows the state of part P before the double-sided adhesive tape is attached, Fig. 8 shows the state of part P after the double-sided adhesive tape is attached, and Fig. 9 shows a cross section taken along line CC in Fig. 8.

[0047] 7, the lower frame member 61b and the right frame member 61r are assembled so that their butt joints intersect at a substantially right angle. Here, a tip end 63be of a longitudinal flange portion 63b of the lower frame member 61b is shaped to extend in a direction perpendicular to the longitudinal direction of the right frame member 61r so as to bite into the center of the flange portion 63r of the right frame member 61r.

[0048] A positioning marker 65 is formed near where the long side 63bl of the flange portion 63b of the lower frame member 61b and the short side 63rs of the flange portion 63r of the right frame member 61r face each other. The positioning marker 65 is a groove formed in a long and narrow rectangle, and is provided in the flange portion 63r itself.

[0049] Here, the positioning marker 65 does not exceed the inner long side 63rl of the flange portion 63r, and is formed only up to this long side 63rl. This prevents the urethane concentrate from seeping into the flange portion 63r side through the groove of the positioning marker 65 when the urethane concentrate is poured into the insulating door.

[0050] In this embodiment, a positioning marker 65 parallel to the long side 63bl of the flange portion 63b of the lower frame member 61b is formed in a tip region 63re of the flange portion 63r of the right frame member 61r. Here, the "tip region" refers to the vicinity of the end face including the short side 63rs of the flange portion 63r, and means a region where the positioning marker 65 can be formed close to the short side 63rs. Details of the positioning marker will be described in FIG. 9.

[0051] When the double-sided adhesive tape is applied to the flange portions 63r and 63b, the application is performed with the positioning marker 65 as a reference.

[0052] 8, when attaching the right double-sided adhesive tape (hereinafter referred to as the right vertical tape portion) 64r, the right vertical tape portion 64r is attached so that the tip portion 64re of the right vertical tape portion 64r does not extend beyond the positioning marker 65 and does not reach the lower side. In this case, the attachment position is determined by the positioning marker 65.

[0053] On the other hand, when attaching the lower double-sided adhesive tape (hereinafter referred to as the lower horizontal tape portion) 64b, the lower horizontal tape portion 64b is attached so that the long side 64bl side of the tip portion 64be of the lower horizontal tape portion 64b does not extend beyond the positioning marker 65 and reach the upper side.

[0054] That is, the positioning marker 65 is disposed so as to face the short side of the tip portion of one double-sided adhesive tape 64r, and is disposed so as to face the long side 64bl of the tip portion of the other double-sided adhesive tape 64b.

[0055] FIG. 8 shows a state after double-sided adhesive tape has been attached to the flange portions 63b and 63r using the positioning markers 65.

[0056] A lower horizontal tape portion 64b is attached to a flange portion 63b formed along the longitudinal direction of the lower frame member 61b. Here, a tip end 64be of the lower horizontal tape portion 64b is attached so as to extend toward the center of the right frame member 61r in a direction perpendicular to the longitudinal direction of the right frame member 61r, following the tip end 63be of the flange portion 63b.

[0057] That is, the tip 64be of the lower horizontal tape portion 64b is attached so as to extend toward the center of the right frame member 61r. In this case, the lower horizontal tape portion 64b is attached with a gap between it and the positioning marker 65.

[0058] On the other hand, a right vertical tape portion 64r is attached to a flange portion 63r formed along the longitudinal direction of the right frame member 61r. Here, a tip end 64re of the right vertical tape portion 64r is shaped to extend toward the lower horizontal tape portion 64b in a direction perpendicular to the longitudinal direction of the lower frame member 61b. The tip end 64re of the right vertical tape portion 64r is attached so as to extend to just before the positioning marker 65.

[0059] Here, the positioning marker 65 is formed in a groove shape, and has a width (W) of 1 mm and a length (L) of 10 mm as shown in Fig. 7. Also, the width (WT) of the horizontal tape portion and the vertical tape portion is set to 15 mm and the thickness is set to 0.4 mm as shown in Fig. 8. Therefore, as can be seen from Fig. 8, the length of the positioning marker 65 is shorter than the width of the horizontal tape portion and the vertical tape portion.

[0060] Next, the configuration of the positioning marker 65 will be described with reference to FIG.

[0061] 9, the lower frame member 61b has a flange portion 63b formed facing inward, and similarly the right frame member 61b has a flange portion 63r formed facing inward. Double-sided adhesive tapes 64r and 4b are interposed between the flange portions 63r and 63b, respectively, and are used to adhere the glass plate 60. A positioning marker 65 is provided in a tip region 63re of the flange portion 63r.

[0062] The positioning marker 65 is a groove formed near the tip 63rs of the flange 63r of the right frame member 61r. The groove is formed by molding at the same time as the right frame member 61r is formed. The reason for forming the positioning marker 65 as a groove is as follows.

[0063] If the positioning marker 65 were formed in a convex shape, when the end of the right vertical tape portion 64r overlaps with the positioning marker 65, this portion would be higher than other areas, causing a problem similar to that of the present invention. For this reason, by forming the positioning marker 65 as a groove, even if the right vertical tape portion 64r overlaps, the tape portion is stored in the groove, and the above-mentioned problem does not occur. The depth (D) of the groove is set to 0.3 mm, which is shorter than the thickness of the tape portion.

[0064] Here, a protrusion 61bp is formed on the glass plate 60 side of the lower frame member 61b, protruding from the flange portion 63b toward the glass plate 60. This protrusion 61bp has a dimension similar to the thickness of the glass plate 60, and protects the side surface of the glass plate 60 from external forces. Of course, the other frame members 61u, 61l, and 61r have a similar configuration.

[0065] Thus, in this embodiment, the tip 64re of the right vertical tape portion 64r is attached so that it does not extend beyond the positioning marker 65 and reach below, and similarly, the long side 65bl of the tip 64be of the lower horizontal tape portion 64b is attached so that it does not extend beyond the positioning marker 65 and reach above.

[0066] Therefore, the right vertical tape portion 64r and the lower horizontal tape portion 64b do not overlap, which solves the problem of the glass plate 60 floating and adversely affecting the external design, as well as the problem of the adhesive strength being reduced only in the portion where the glass plate is floating. EXAMPLES

[0067] Next, a second embodiment of the present invention will be described. The second embodiment aims to prevent the leading end of the long side of the horizontal tape section or the leading end of the long side of the vertical tape section from being attached at a position beyond the normal position.

[0068] Its features include at least a rectangular exterior panel provided on the outer surface and a rectangular door frame provided on the outer peripheral edge of the exterior panel, with at least two adjacent sides of the door frame and the outer peripheral edge on the back side of the exterior panel being adhered using double-sided adhesive tape, and a positioning marker is formed in the area of ​​the door frame where the double-sided adhesive tape is attached, for determining the position of the tip of one of the two double-sided adhesive tape sides in the application direction of the double-sided adhesive tape.

[0069] 10 to 14 are diagrams for explaining the position of a positioning marker on the insulation door 4 on the right side of the freezer compartment 13. This positioning marker has the function of determining the position of the end face of the double-sided adhesive tape in the application direction of the double-sided adhesive tape.

[0070] Fig. 10 shows the front of the insulated door 4, and almost the entire outer surface of the insulated door 4 is covered with a glass plate 70. A pull handle 78 is provided on the upper part. Fig. 11 shows the front of the insulated door 4 with the glass plate 70 removed, and the rectangular door frame is formed of an upper frame member on the upper side, a lower frame member on the lower side, a left frame member on the left side, and a right frame member on the right side when viewed from the front. Since these members have a similar configuration to the first embodiment, reference numbers are omitted in Fig. 11.

[0071] Flange portions 73u, 73b, 73l, and 73r (see FIG. 14; however, flange portions 73u, 73b, and 73l are not shown) are formed on each of the frame members. Furthermore, as shown in FIG. 14, backing plates 76u, 76b, 76l, and 76r are interposed between these flange portions 73 and the glass plate 70. Furthermore, an upper double-sided adhesive tape 74u on the upper side, a lower double-sided adhesive tape 74b on the lower side, a left double-sided adhesive tape 74l on the left side, and a right double-sided adhesive tape 74r on the right side are attached to the backing plates 76u, 76b, 76l, and 76r corresponding to each of the frame members when viewed from the front.

[0072] Here, similarly to the first embodiment, a rectangular frame-shaped tape application area is formed in the door frame by backing plates 76u, 76b, 76l, and 76r that constitute the door frame, and double-sided adhesive tapes 74u, 74b, 74l, and 74r are applied to the door frame as shown in FIG. 11.

[0073] In the second embodiment, when the refrigerator is placed on the floor of a house and stands upright, the upper double-sided adhesive tape 74u and the lower double-sided adhesive tape 74b are arranged to extend in a direction perpendicular to the direction of gravity (approximately horizontal direction), and therefore may be described as "upper horizontal tape portion 74u" and "lower horizontal tape portion 74b." Similarly, the left double-sided adhesive tape 74l and the right double-sided adhesive tape 74r are arranged to extend in the direction of gravity, and therefore may be described as "left vertical tape portion 74l" and "right vertical tape portion 74r."

[0074] In this embodiment, as shown in the Q1 to Q4 parts, which are the four corners of the door frame, the positioning markers, which are a feature of this embodiment, are formed on each frame member. The Q1 to Q4 parts are based on the same concept. For this reason, the Q1 part is shown enlarged in FIG. 12.

[0075] Next, details of part Q1 will be described with reference to Fig. 12 to Fig. 14. Fig. 12 shows the state of part Q1 before the double-sided adhesive tape is attached, Fig. 13 shows the state of part Q1 after the double-sided adhesive tape is attached, and Fig. 14 shows the DD cross section of Fig. 13.

[0076] 12, the lower frame member 71b and the right frame member 71r are assembled so that their butt joints intersect at a substantially right angle. Here, the tip 76be of the longitudinal backing plate 76b of the lower frame member 71b is shaped to extend in a direction perpendicular to the longitudinal direction of the right frame member 71r until it comes into contact with the long side 76rl of the backing plate 76r of the right frame member 71r.

[0077] A positioning marker 75 is formed near the short side 76rs of the backing plate 76r of the right frame member 71r. In this embodiment, the positioning marker 75, which is parallel to the short side 76rs of the backing plate 76r of the right frame member 71r, is formed in the tip region 76re of the backing plate 76r of the right frame member 71r. Here, the "tip region" refers to the vicinity of the end face including the short side 76rs of the backing plate 76r, and means the region where the positioning marker 75 can be formed close to the short side 76rs. The details of the positioning marker will be described in FIG. 14.

[0078] When attaching the double-sided adhesive tape to the backing plate 76r, the tape is attached based on the positioning marker 75. In Fig. 12, the backing plate 76r of the right frame member 71r extends downward so as to abut against the lower frame member 71b, and therefore the positioning marker 75 is formed in the tip region 76re of the backing plate 76r.

[0079] That is, as shown in FIG. 13, when attaching the right double-sided adhesive tape (hereinafter referred to as the right vertical tape portion) 74r, the tip portion 74re of the right vertical tape portion 74r is attached so as not to extend beyond the positioning marker 75 and below.

[0080] On the other hand, when attaching the lower double-sided adhesive tape (hereinafter referred to as the lower horizontal tape portion) 74b, the lower horizontal tape portion 74b is attached so that the tip portion 74be side of the lower horizontal tape portion 74b does not reach the right vertical tape portion 74r.

[0081] FIG. 13 shows a state after the double-sided adhesive tape has been attached to the backing plate 76r using the positioning markers 75.

[0082] A right vertical tape portion 74r is attached to a backing plate 76r formed along the longitudinal direction of the right frame member 71r. Here, a tip end 74re of the right vertical tape portion 74r is shaped to extend in a direction perpendicular to the longitudinal direction of the lower frame member 71b. The tip end 74re of the right vertical tape portion 74r is attached so as to extend to just before the positioning marker 75.

[0083] Here, the positioning marker 75 is formed in a groove shape, and similarly to the first embodiment, the width is set to 1 mm and the length is set to 10 mm. Also, similarly to the first embodiment, the width of the horizontal tape portion and the vertical tape portion are set to 15 mm and the thickness is set to 0.4 mm. Therefore, as can be seen from Fig. 12, the length of the positioning marker 75 is shorter than the width of the horizontal tape portion and the vertical tape portion.

[0084] Next, the configuration of the positioning marker 75 will be described with reference to FIG.

[0085] 14, a flange portion 73r is formed on the right frame member 71r facing inward. A backing plate 76r is sandwiched between the flange portion 73r and the glass plate 70, and a double-sided adhesive tape 74r is interposed between the glass plate 70 and the backing plate 76r to adhere the glass plate 70. A positioning marker 75 is provided on a tip region 76re of the backing plate 76r.

[0086] The positioning marker 75 is a groove formed near the tip 76re of the backing plate 76r of the right frame member 71r. The groove is formed by molding at the same time as the backing plate 76r is formed. The reason for forming the positioning marker 75 as a groove is as follows.

[0087] If the positioning marker 75 were formed in a convex shape, when the end of the right vertical tape portion 74r overlaps with the positioning marker 75, this portion would be higher than other areas, causing a problem similar to that of the present invention. For this reason, by forming the positioning marker 75 as a groove, even if the right vertical tape portion 74r overlaps, the tape portion is stored in the groove, and the above-mentioned problem does not occur. Here, the depth (D) of the groove is set to 0.3 mm, which is shorter than the thickness of the tape portion.

[0088] In this manner, in this embodiment, the tip 74re of the right vertical tape portion 74r is affixed so as not to extend beyond the positioning marker 75 and below, using the positioning marker 75 as a reference.

[0089] Here, a protrusion 71bp is formed on the glass plate 70 side of the lower frame member 71b, protruding from the flange portion 73b toward the glass plate 70. This protrusion 71bp has a dimension similar to the thickness of the glass plate 70, and protects the side surface of the glass plate 70 from external forces.

[0090] 13, the side of the lower frame member 71b including the backing plate 76b may be extended, and the right frame member 71r may be shortened accordingly, and the positioning marker 75 may be provided on the extended portion of the backing plate 76b. In this case, the positioning marker 75 is formed parallel to the short side 76be of the backing plate 76b.

[0091] Therefore, according to this embodiment, the problem of the end of the long side of the horizontal tape section or the end of the long side of the vertical tape section being affixed at a position beyond the normal position, making it visible through the glass plate and resulting in a poor appearance, can be solved. EXAMPLES

[0092] Next, a third embodiment will be described. This embodiment also has substantially the same configuration as the second embodiment, but uses a different heat-insulating door.

[0093] Similar to the second embodiment, this application example aims to prevent the leading end of the vertical tape portion in the long side direction from being attached at a position beyond the normal position.

[0094] And, like the second embodiment, its feature is that a positioning marker is formed in the area of ​​the door frame where the double-sided adhesive tape is attached, which determines the position of the tip of the double-sided adhesive tape in the application direction of the double-sided adhesive tape.

[0095] 16 to 18 are diagrams for explaining the position of a positioning marker on the heat-insulating door 5 of the freezer compartment 14. This positioning marker has the function of determining the position of the tip of the double-sided adhesive tape in the application direction of the double-sided adhesive tape.

[0096] 15 shows the front of the insulating door 5, and almost the entire outer surface of the insulating door 5 is covered with a glass plate 80. An upper cover member 88 is provided on the upper part. The upper cover member 88 may be configured to be provided with a switch mechanism. In other words, if the insulating door 5 is an electrically operated pull-out door, pressing the upper cover member 88 will activate the switch mechanism, and the insulating door 5 will be pulled out by the electric motor.

[0097] Moreover, Figure 16 shows the front of the insulated door 4 with the glass plate 80 removed, and the rectangular door frame 81 is formed, when viewed from the front, from an upper cover member (hereinafter referred to as an upper frame member) 81u on the upper side, a lower frame member 81b on the lower side, a left frame member 81l on the left side, and a right frame member 81r on the right side.

[0098] Flange portions 83u, 83b, 83l, and 83r (see FIG. 18, but the flange portions 83r, 83b, and 83l are not shown) are formed on the frame members 81u, 81b, 81l, and 81r, respectively. In addition, backing plates 86u, 86b, 86l, and 86r (but the backing plates 86u, 86b, and 86l are not shown) are interposed between these flange portions 83 and the glass plate 80, as shown in FIG.

[0099] In addition, an upper double-sided adhesive tape 84u on the upper side and a lower double-sided adhesive tape 84b on the lower side, as well as a left double-sided adhesive tape 84l on the left side and a right double-sided adhesive tape 84r on the right side are affixed to each of the backing plates 86u, 86b, 86l, 86r corresponding to each of the frame members 81u, 81b, 81l, 81r when viewed from the front.

[0100] Here, similarly to the second embodiment, a rectangular frame-shaped tape application area is formed in the door frame 81 by the backing plates 86u, 86b, 86l, and 86r that constitute the door frame 81, and double-sided adhesive tapes 84u, 84b, 84l, and 84r are applied thereto, as shown in FIG. 16.

[0101] In the present embodiment, when the refrigerator is placed on the floor of a house and in an upright position, the upper double-sided adhesive tape 84u and the lower double-sided adhesive tape 84b are arranged to extend in a direction perpendicular to the direction of gravity (approximately horizontal direction), and therefore may be described as "upper horizontal tape portion 84u" and "lower horizontal tape portion 84b." Similarly, the left double-sided adhesive tape 84l and the right double-sided adhesive tape 84r are arranged to extend in the direction of gravity, and therefore may be described as "left vertical tape portion 84l" and "right vertical tape portion 84r."

[0102] In this embodiment, as shown by the R1 and R2 parts, which are the two upper corners of the door frame 81, positioning markers, which are a feature of this embodiment, are formed on the frame member. The R1 and R2 parts are based on the same concept. For this reason, the R1 part is shown enlarged in Figure 17. Note that the state where the double-sided adhesive tape is not attached is omitted here, as it is substantially the same as Figure 12.

[0103] Next, details of the R1 portion will be described with reference to Fig. 17 and Fig. 18. Fig. 17 shows the state of the R1 portion after the double-sided adhesive tape has been attached, and Fig. 18 shows an EE cross section of Fig. 17.

[0104] 17, the upper frame member 81u and the right frame member 81r are assembled so that their butt portions intersect at a substantially right angle. Here, the tip portion 86ue of the longitudinal backing plate 86u of the upper frame member 81u is shaped to extend in a direction perpendicular to the longitudinal direction of the right frame member 81r until it comes into contact with the long side 86rl of the backing plate 86r ​​of the right frame member 81r.

[0105] A positioning marker 85 is formed near the short side 86rs of the backing plate 86r ​​of the right frame member 81r. In this embodiment, the positioning marker 85, which is parallel to the short side 86rs of the backing plate 86r ​​of the right frame member 81r, is formed in a tip region 86re of the backing plate 86r ​​of the right frame member 81r. Here, the "tip region" refers to the vicinity of the end face including the short side 86rs of the backing plate 86r, and means a region where the positioning marker 85 can be formed close to the short side 86rs. Details of the positioning marker will be described in FIG. 18.

[0106] When attaching the double-sided adhesive tape to the backing plate 86r, the tape is attached based on the positioning marker 85. In Fig. 17, the backing plate 86r ​​of the right frame member 81r extends to a position where it abuts against the upper frame member 81u, and therefore the positioning marker 85 is formed in the tip region 86re of the backing plate 86r.

[0107] That is, as shown in FIG. 17, when attaching the right double-sided adhesive tape (hereinafter referred to as the right vertical tape portion) 84r, the tip portion 84re of the right vertical tape portion 84r is attached so as not to extend beyond the positioning marker 85 and reach the upper side.

[0108] On the other hand, when the upper double-sided adhesive tape (hereinafter referred to as the upper horizontal tape portion) 84u is applied, the tip portion 84ue of the upper horizontal tape portion 84u is applied so as not to reach the right vertical tape portion 84r.

[0109] FIG. 17 shows a state after the double-sided adhesive tape has been attached to the backing plate 86r ​​using the positioning markers 85.

[0110] A right vertical tape portion 84r is attached to a backing plate 86r ​​formed along the longitudinal direction of the right frame member 81r. Here, a tip end 84re of the right vertical tape portion 84r is shaped to extend in a direction perpendicular to the longitudinal direction of the upper frame member 81u. The tip end 84re of the right vertical tape portion 84r is attached so as to extend to just before the positioning marker 85.

[0111] Here, the positioning marker 85 is formed in a groove shape, and similarly to the second embodiment, the width is set to 1 mm and the length is set to 10 mm. Also, similarly to the second embodiment, the width of the horizontal tape portion and the vertical tape portion are set to 15 mm and the thickness is set to 0.4 mm. Therefore, as can be seen from Fig. 17, the length of the positioning marker 85 is shorter than the width of the horizontal tape portion and the vertical tape portion.

[0112] Next, the configuration of the positioning marker 85 will be described with reference to FIG.

[0113] In Fig. 18, an upper frame member 81u has a flange portion 83u formed facing inward. A backing plate 86r ​​is sandwiched between the flange portion 83u and the glass plate 80, and a double-sided adhesive tape 84r is interposed between the glass plate 80 and the backing plate 86r ​​to adhere the glass plate 80. A positioning marker 85 is provided in a tip region 86re of the backing plate 86r. Here, the tip region 86re refers to a region including the position of the side of the glass plate 80, as shown in the figure.

[0114] The positioning marker 85 is a groove formed in a tip region 86re of a backing plate 86r ​​of the right frame member 81r. The groove is formed by molding at the same time as the backing plate 86r ​​is formed. The reason for forming the positioning marker 75 as a groove is as follows.

[0115] If the positioning marker 85 were formed in a convex shape, when the end of the right vertical tape portion 84r overlaps with the positioning marker 85, this portion would be higher than other areas, causing a problem similar to that of the present invention. For this reason, by forming the positioning marker 85 as a groove, even if the right vertical tape portion 84r overlaps, the tape portion is stored in the groove, and the above-mentioned problem does not occur. Here, the depth (D) of the groove is set to 0.3 mm, which is shorter than the thickness of the tape portion.

[0116] In this manner, in this embodiment, the tip portion 84re of the right vertical tape portion 84r is affixed so as not to extend beyond the positioning marker 85 and above the positioning marker 85, using the positioning marker 85 as a reference.

[0117] Here, a protrusion 81bp that protrudes toward the glass plate 80 is formed on the glass plate 80 side of the backing plate 86r. This protrusion 81bp is located between the glass plate 80 and the upper cover member 81u, and holds the side surface of the glass plate 80 and positions the upper cover member 81u. However, if the upper cover member 81u constitutes a switch mechanism, the protrusion 81bp will have a guiding function for the upper cover member 81u.

[0118] In this manner, also in this embodiment, the tip end 84re of the right vertical tape portion 84r is attached so as not to exceed the positioning marker 85 and reach the upper side, using the positioning marker 85 as a reference.

[0119] Therefore, according to this embodiment, the problem of the tip of the long side of the vertical tape portion being affixed at a position beyond the normal position, making it visible through the glass plate and resulting in a poor appearance, can be solved.

[0120] The present invention is not limited to the above-described embodiments, but includes various modified examples. The above-described embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those having all of the configurations described. In addition, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. It is also possible to add, delete, or replace other configurations with respect to the configuration of each embodiment. [Explanation of symbols]
