Abstract: PROBLEM TO BE SOLVED: To manufacture refrigerator doors at a low cost and enhance a fixing strength of a cold air shielding plate and its appearance. SOLUTION: With an ultrasonic welding hole 7 having a protruding shape, a door lining 8 and a cold air shielding plate 9 are deformed to form recessed portions respectively which are fitted with each other and are connected with each other by welding. Due to such a construction, fastening members can be obviated and a boring of the door lining 8 and the cold air shielding plate 9, seal members and sealing works which are necessary when the fastening members are used can be also obviated so that the cold air shielding plate 9 can be fixed at a low cost. Furthermore, the cold air shielding plate 9 can improve its fixing strength and its appearance.

Abstract: PROBLEM TO BE SOLVED: To provide a hinge reinforcing plate to decrease protrusion of a hinge mounting part and increase the content volume of a refrigerator having the same height and facilitate positioning. SOLUTION: A refrigerator comprises an outer casing recessed part 4 formed in the top surface of the outer box of a refrigerator a hinge plate recessed part 7 formed along a position situated on the outer box recessed part 4 side; a hinge reinforcing plate recessed plate 7 positioned on the heat insulation material 3 side of the outer box recessed part 4; a caulking 12 fixing the outer box recessed part 4 and the hinge reinforcing plate recessed part 5; a screw 8 to fasten the hinge plate recessed part 7 and the hinge reinforcing recessed part 5 against each other; a cover 15 to cover a hinge plate 6; a hinge pin 14 arranged at one end of a hinge plate; and a hinge support recessed part 19 positioned facing the hinge pin 14. A hinge plate 6 is extended through the outer box recessed part 4 and securely fastened at the hinge reinforcing plate 5 and the hinge fastening part is positioned at a part situated in a level lower than that of the outer peripheral flange of the hinge plate 6. Protrusion of the hinge mounting part is reduced, the content volume of the refrigerator having the same height is increased, and constantly stable positioning is practicable.

Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator enabled of easily executing the piping work of inserting piping such as suction pipe into an inner box and forming the piping. SOLUTION: The ineffective space of a condenser chamber for refrigeration 20 in the longitudinal direction can be reduced by securing the size of the piping by inserting the refrigerant pipe 33 of the final piping form of a reverse U shape into a long hole 35 arranged to an inner box 11 and fitting the refrigerant pipe 33 into a take out hole 36, and reducing the dispersion of the piping size.

Abstract: PURPOSE:To simplify the mounting operation of a gasket and to prevent the sealing failure after the mounting by forming sealing fins for holding sealability in pressure contact with the mounting legs of the gasket provided at the peripheral frame of an inner plate side in a space for mounting the gasket of a sash. CONSTITUTION:A heat insulation door 1 for a refrigerator comprises an outer plate 2, an inner plate 3, a peripheral frame 4 for fixing the peripheries of the plates 2, 3, and a heat insulator 5 filled in the space surrounded by them. A space 12 is provided at a sash 10 provided between the plate 3 of the door 1 and the end of the frame 4, and mounting legs 17 provided at a gasket 11 is inserted into the groove 16 formed in the space 12. The legs 17 are integrally formed with a baglike part 18 in contact with an outer box 7 via a coupling piece 19. In this case, sealing fins 22 in contact with the ends of the leg 17 are integrally formed with the sash 10. Thus, when the legs 17 are inserted into the grooves 16, the fins do not disturb it, thereby easily inserting the fins into the grooves 16.
