Cooling to an appropriate temperature.

  FIG. 3 is a perspective view showing the door 8 of the refrigerator compartment 3 alone. As is clear from this figure, the door 8 is composed of a rectangular front plate 16 and a frame 17 that surrounds the four sides around it. And an inner surface plate (not shown) on the back side, and a space between them is filled with a heat insulating material (not shown) such as foamed polyurethane.

  The front plate 16 is made of glass, that is, a glass plate and has translucency. On the back surface of the front plate 16, a coating film made of a paint having the same color as the appearance of the refrigerator body 1 or a color different from that (for example, white, black, silver, etc.) is provided. It has translucency, and allows translucent display of operation key units other than the operation key unit 11 of the operation panel unit 10.

  On the other hand, the frame 17 is made of plastic and does not have translucency. FIG. 1 shows a frame 17 on one side (left side in FIG. 3) of the front plate 16 in a cross-sectional shape. Mainly, an outer portion 17a along the outer peripheral surface of the front plate 16 and the outer portion 17a are generally “ The inner portion 17b extends inwardly along the rear surface of the front plate 16 and has a front portion (the lower portion in FIG. 1) of the inner portion 17b, which is the front plate fixing portion. ) Is formed with an adhesive injection groove 18. The groove 18 extends long along each side of the frame 17 and has a semicircular cross section.

  Further, a protruding portion 19 is formed in a portion of the inner portion 17b outside the groove 18 at a corner portion of the connecting portion with the outer portion 17a. This raised portion 19 also extends long along each side of the frame 17, and has a beveled chamfered portion 20 on the front side, and this chamfered portion 20 is located on the rear side of the peripheral portion of the front plate 16. This corresponds to the chamfered portion 21 formed in a slope shape. The front plate 16 is also formed with a chamfered portion 22 on the front side of the peripheral edge.

Further, a rib 23 is formed at the inner end portion of the inner portion 17b from the groove 18. The rib 23 also extends long along each side of the frame 17 and protrudes forward.
FIG. 3 shows a hinge portion 24 provided at the upper end portion of the left side portion of the door 8. Although not shown, a similar hinge is also provided at the lower end portion of the left side portion of the door 8.

In addition, the doors 9 and 12 to 15 other than the door 8 are configured in the same manner as the door 8 (the front plate 16 and the frame 17 and the like) except that the operation panel unit 10 is not provided.
Then, as shown in FIG. 4, an adhesive 25 is injected into the groove 18, and then, as shown in FIG. 5, the front plate 16 is aligned with the inner portion 17b of the frame 17 from the front and pressed. ing. As a result, the adhesive 25 is pressed and spread between the front plate 16 and the inner portion 17 b of the frame 17, and the inner portion 17 b (particularly, the raised portion 19 and the rib 23 are fixed to the front plate fixing portion of the frame 17. And the portion of the front plate 16 opposite to that of the front plate 16 are brought into contact with and adhered to each other.

  Before attaching the front plate 16 and the frame 17, carefully clean the bonding surface using a cleaning solution such as alcohol and confirm that no dust or oil remains on the bonding surface. And then bond.

  Moreover, in order to keep the adhesive capability of the adhesive 25 in a good state, it is preferable to maintain the temperature of the environment in which the bonding is performed at an appropriate temperature. In this case, it is preferable not only to control the temperature of the front plate 16, the frame 17, and the adhesive 25 that are actually bonded, but also to set the entire space for performing the bonding operation to an appropriate temperature. It is preferable to avoid and manage until the state of adhesion becomes stable under an appropriate temperature.

  Also, since it is assumed that the bonding ability is not sufficiently high immediately after bonding, the bonding surface should be horizontal to prevent the bonding surface from shifting immediately after bonding. It is preferable to lay down and store.

  In this way, the front plate 16 is fixed to the frame 17, and the fixed form is a form (full flat) in which the front plate 16 is completely exposed to the peripheral edge. I do it. The fixing by the adhesive 25 is different from the fixing by the conventional double-sided tape, and there is no concern that the front plate 16 will drop off due to the peeling of the double-sided tape even in long-term use. Can be improved.

  Further, since the application of the adhesive 25 itself can be clearly identified by the groove 18 and the adhesive 25 only needs to be injected along the groove 18, the application of the adhesive 25 can be performed accurately and easily. Manufacturing workability can be improved.

  In addition, in the present embodiment, a raised portion 19 is formed at a portion outside the groove 18 of the frame 17. FIG. 6 shows a situation where the raised portion 19 is not provided, and between the front plate 16 and the inner portion 17b of the frame 17 and between the edge portion of the front plate 16 and the outer portion 17a of the frame 17. Are connected to each other in a simple L shape, and are pressed and spread between the front plate 16 and the inner portion 17b of the frame 17 to reach between the end edge portion of the front plate 16 and the outer portion 17a of the frame 17. The adhesive 25 becomes visible from the front, and the quality is impaired.

  On the other hand, in the present embodiment, the bulging portion 19 is formed in the portion outside the groove 18 of the frame 17, so that the end of the front plate 16 is between the front plate 16 and the inner portion 17 b of the frame 17. An adhesive that is intricately connected between the edge portion and the outer portion 17a of the frame 17 along the outer surface shape of the raised portion 19, and is pressed and spread between the front plate 16 and the inner portion 17b of the frame 17. 25 also becomes difficult to see from the front as shown in FIG. 5, and good quality can be ensured.

  In the present embodiment, the chamfered portion 21 exists at the edge of the front plate 16, and the chamfered portion 20 corresponding to the chamfered portion 21 is formed in the above-described raised portion 19. FIG. 7 shows the situation (19 ′) when the raised portion 19 is formed in a rectangular cross section, and a rectangular recess 101 is formed at the edge of the front plate 16 correspondingly. Even if it does in this way, the effect which makes the above-mentioned spreading adhesive 25 difficult to see from the front is acquired. However, it is difficult to form the rectangular recess 101 at the edge of the front plate 16 in terms of glass cutting technology.

  In that respect, it is easy to form the chamfered portion 21 at the edge of the front plate 16 in terms of glass cutting technology, and the above-described spread adhesive 25 is applied from the front without any difficulty in glass cutting technology. The effect of making it difficult to see is obtained.

  Further, in the present embodiment, ribs 23 are formed on the inner side of the groove 18 of the frame 17. As a result, it is possible to prevent the adhesive 25 from leaking inward (too wide), and the adhesive 25 can be fastened to the front plate fixing portion of the frame 17, so that the front plate 16 can be more firmly fixed. . In addition, although a coating film is provided on the back surface of the front plate 16, when the spread adhesive 25 leaks inward, it mixes with the heat insulating material (for example, foamed polyurethane, etc.) existing on the back side of the front plate 16, thereby causing chemicals. The change causes the coating film on the back surface of the front plate 16 to be eroded. As a result, the coating film is partially removed, and the part where the chemical change has occurred becomes visible from the front. In the present embodiment, the ribs 23 of the frame 17 can prevent the adhesive 25 from leaking inward, so that the quality can be ensured satisfactorily.

  8 and 9 show the second and third embodiments. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only the part is described.

[Second Embodiment]
In the second embodiment shown in FIG. 8, the groove 31 of the frame 17 is formed in a wavy shape in which a plurality of rows are replaced with the above-mentioned single groove 18. Even in this case, the adhesive 25 can be prevented from being excessively spread and the adhesive 25 can be fastened to the front plate fixing portion of the frame 17, so that the front plate 16 can be more firmly fixed. In addition, partial removal of the coating film on the back surface of the front plate 16 due to leakage of the adhesive 25 and deterioration of quality due to the removal can be prevented.

[Third Embodiment]
In the third embodiment shown in FIG. 9, the concavo-convex portion 41 is formed in the portion of the front plate 16 that contacts the adhesive 25. Even in this case, the adhesive 25 can be prevented from being excessively spread and the adhesive 25 can be fastened to the front plate fixing portion of the frame 17, so that the front plate 16 can be more firmly fixed. In addition, partial removal of the coating film on the back surface of the front plate 16 due to leakage of the adhesive 25 and deterioration of quality due to the removal can be prevented.

The third embodiment may be implemented in combination with the second embodiment.
Further, the frame 17 is not limited to the one surrounding the four sides around the front plate 16, and may be one on the left and right sides, for example. Further, the frame 17 may be made of metal other than plastic, for example.
The hinged doors 8 and 9 are subjected to an impact caused by a collision with the heat insulating box 2 when closed on the side opposite to the hinge side, so that the frame 17 and the front plate 16 on the side opposite to the hinge side are in contact with each other. It is preferable to increase the fixing strength.

  In addition, regarding the fixation between the frame 17 and the front plate 16, not only the adhesive 25 but also a double-sided tape may be used in combination for temporary fixing until the adhesive 25 is solidified. In this case, it is preferable to provide a predetermined interval between the adhesive and the double-sided tape in order to prevent the adhesive 25 and the double-sided tape from contacting each other. Further, since it is considered that the adhesive 25 before solidification is attracted by gravity and flows downward, it is preferable to attach a double-sided tape directly above the area where the adhesive 25 is applied. In addition, in order to prevent the adhesive 25 from protruding to the outer surface of the door 8 (9, 12 to 15) and being noticed by the user, the appearance of the door 8 (9, 12 to 15) is prevented. It is good also as a structure which fixes an edge part with a double-sided tape, and apply | coats an adhesive agent on the inner side.

Furthermore, the storage itself is not limited to the refrigerator, and may be a warm storage.
