の締付作業に多大の時間を要している。A conventional refrigerator door has a structure as shown in FIG. 1 is the door liner, which is the inside of the refrigerator. 2
is a rigid polyurethane foam. 3 is a door outer plate, and 6 is a door outer frame. 7 is glass wool, and 4 is a screw that fixes the door liner and the door outer frame 6. 5 is the door backing. It is composed of the above members. These assembly operations include assembling the glass wool 7 into the door liner and installing the screws 4 that attach the door outer frame 6 and the door liner 1.
The tightening work takes a lot of time.

を簡単にし、作業時間を著しく短縮するものである。The present invention relates to the structure of a refrigerator door, and includes a door outer panel,
The door frame and door liner are assembled by utilizing the adhesive strength of rigid polyurethane foam, which simplifies the assembly process and significantly shortens the working time.

時間の短縮を図るものである。Rigid polyurethane foam is used as a heat insulating material, and it adheres well to oil removal materials that are foamed and hardened. Therefore, when a rigid polyurethane foam is filled as a heat insulating material into the gap created by the combination of the outer frame, outer plate, and door liner of a refrigerator door, these members are integrated through the rigid polyurethane foam. Therefore, the glass wool used on the back side of the door liner is also eliminated, reducing assembly time.
以下本発明の一実施例を第２図、第３図により説明する
。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

８と発泡下層９を合せる。1 is a door liner, and 2 is a rigid polyurethane foam. 3 is the outer panel of the door, and 6 is the outer frame of the door. 8 is a foamed upper layer, and 9 is a foamed lower layer. As a procedure for assembling these members, the door outer panel 3 and the door outer frame 6 are assembled and set on the foam lower layer 9. A foaming stock solution is injected onto the door outer panel 3, and before the foaming reaction is completed, the foaming upper layer 8 and the foaming lower layer 9 in which the door liner 1 is set are combined.
これで発泡反応を終了させる。発泡反応終了後発泡層よ
り扉を取り外し、組立作業を完了する。This completes the foaming reaction. After the foaming reaction is complete, remove the door from the foam layer and complete the assembly work.

In addition, by filling the back of the door liner with hard polyurethane foam,
At the same time, the use of glass wool material can be eliminated and the work of assembling the glass wool material can be omitted.
