２，３を接続することができる。 After installing both the boxes 2 and 3 so that their respective openings are on the upper surface and their respective opening edges are spaced apart, the outer surface of the inside part 13 of the decorative frame 4 is a part of the first step part 6 and as shown in FIG. The decorative frame 4 is attached to the inner surface of the sealing member 10 so that a part of the outer surface of the second step part 7 is in contact with the inner surface of the clamping part 15a, and there is a gap between the overhanging piece 17 and the front wall 8 of the outer box 3. After the arrangement, the decorative frame 4 is pushed in the depth direction until the overhanging piece 17 comes into contact with the front wall 8 as shown in C, the gap between the inside part 13 and the clamping piece 15 is widened, and the elasticity of the clamping piece 15 is used to At the same time as the first and second step portions 6 and 7 are clamped, the seal member 10 is compressed and deformed, and the degree of insertion of the decorative frame 4 is restricted. Next, as shown in D, by rotating the decorative frame 4 toward the inside of the refrigerator, that is, in the direction of arrow a, and removing the overhanging piece 17 from the front wall 8, the first step 6 is pressed outward against the inside of the refrigerator. As the force acts, the distance between the inside part 13 and the clamping piece 15 increases, and the elasticity of the clamping piece 15 increases.
While a force pressing the second step part 7 inward is applied, and the sealing member 10 is deformed inward to increase the degree of insertion of the decorative frame 4 and strengthen the clamping force, a difference is made on the end surface of the front wall 8. The corner portion of the inserting piece 16 and the overhanging piece 17 are brought into contact with each other to stop the outside part 14 of the refrigerator. Furthermore, the decorative frame 4 is rotated in the direction of arrow a to separate the outside part 14 from the front wall 8, and the back wall 18 is brought into contact with the riser 6a to increase the elasticity of the clamping piece 15 to further strengthen the clamping force. After that, as shown in E, the decorative frame 4 is rotated toward the outside of the refrigerator, that is, in the direction of arrow b, and while the clamping piece 15 is returned to its original position, the insertion piece 16 is inserted into the groove 9 so as to be in contact with the inner wall of the storage wall 8a, and the sealing member 11 is removed. By pressing and deforming the insertion piece 17 and regulating the degree of insertion of the insertion piece 16 by bringing the overhang piece 17 into contact with the rear wall end of the storage wall 8a, both the inner and outer boxes 2 and 3 can be opened with the decorative frame 4 as shown in A. Can be connected.

するものである。 According to the method of connecting both the inner and outer boxes of the present invention, the work of inserting the insert piece of the decorative frame into the groove of the opening edge of the outer box can be easily performed by utilizing the elasticity of the clamping piece of the decorative frame. That is, by rotating the outside part of the decorative frame toward the inside of the refrigerator, the restoring force of the clamping piece that is elastically deformed causes the outside part of the refrigerator to be rotated toward the inside of the refrigerator, and the piece can be easily inserted into the groove at the opening edge of the outer box. In addition, when the outer part of the decorative frame is rotated toward the inner side of the refrigerator, the clamping pieces themselves are elastically deformed, so that the clamping pieces can absorb the pressing force against the inner box opening edge step. The insertion work is completed without deforming the stepped portion.

It is compressed and deformed by the pieces, and it is possible to improve the sealing performance between the decorative frame and the opening edges of both the inner and outer boxes.
