[0024]

According to the configuration of the present invention as described above, the following corresponding effects can be obtained by the above items. (1) The use of a door outer plate made of metal on the design surface side of the handle portion makes it strong in strength, so that the thickness of the synthetic resin body can be reduced, and the guide portion of the handle portion. The heat insulating space of the door can be secured by making the position of the concave portion of the handle base forming shallower.

Since the handle is formed without notching the bent portions on both side surfaces of the door outer plate, the strength of the door is improved.

By using the door outer plate for the handle, the handle design can be simplified,
There is no need to perform surface secondary processing on the same pattern as the door outer plate in the case where the door outer plate is formed by a separate part, and cost can be reduced. (2) By decorating with the hot stamp foil in the same color as the door outer panel, the sense of unity of the design can be achieved and the design is excellent.

By subjecting the hot stamp foil to a hard coat treatment, the surface hardness of the base is improved, so that the base can be protected from being damaged by nails or the like.

(3) By making the cross section of the trim into an E-shape, the insertion groove of the door outer plate and the body can be fitted without using fastening parts such as an adhesive or a screw.

The Z-shape at the time of fitting can improve the fitting force at the time of sub-assembly of the body and the trim.

(4) By filling the inside of the step portion and the gap forming portion with the foamed heat insulating material, the bonding effect between each component as a characteristic of the foamed heat insulating material is provided, and the solid portion is filled with the adhesive material. It can be combined, and the effect of preventing squeaking noise and the like due to the stress when opening and closing the door of each part can be expected.

(5) By filling the hollow portion, the reinforcing ribs, and the like with the foamed heat insulating material, the foamed heat insulating material spreads between the body and the door outer plate, and the heat insulating property is improved.
By making the connection strong, an effect of preventing squeaking noise and the like can be expected.

(6) At the time of sub-assembly of the body and the trim, it can be assembled by being guided by the positioning projections and the notches.
It is possible to improve the workability and to reduce the defect rate such as cracking or chipping of a part which is elongated and easily breakable like trim.

(7) By fitting the protrusion for preventing the detachment of the trim into the groove for preventing the detachment of the door cap, the fitting can be surely performed, and the gap between the trim and the door cap is prevented from being designed. Since they are arranged, improvement can be achieved.

When the door is opened and closed, even if an excessive external force is applied to the trim, it is securely fitted, so that cracks and looseness of each part can be prevented.

(8) The front end of the trim is not formed with a fitting structure with the body. Therefore, after the door outer plate is sandwiched, the tab is fitted into the square hole of the base, so that the trim from the door outer plate is removed. This prevents floating and improves the strength of the tip.

As the effect (9), the same effect as in the above item (8) can be obtained.

(10) The fitting between the base and the body can be constituted by a sub-assembly, and the joint between the base and the body can be smoothly connected without any gap even if a nail or the like abuts. Since it can be formed and furthermore, it is constituted so that it may fit tightly, so that leakage of the foamed heat insulating material can be prevented.

(11) When the hot stamp foil is transferred to the base, if the step is sharp, the foil is likely to be cut or wrinkled. Therefore, by forming a rounded portion on the fitting flange, the foil is easily stretched and defective. The structure is designed to reduce the rate and to be connected flush to improve the design when fitted with the door cap.

(12) By sandwiching the door outer plate with the wedge, there is no gap between the base and the door outer plate, so that the design can be prevented from deteriorating and the foam insulation can be prevented from leaking.

(13) Since the pressing piece portion has a larger flat portion than the other portions of the wedge, the contact area of the finger when pressed with a finger is increased, so that the wedge can be engaged with a weak force and the finger can be engaged. The location to be pressed is clarified, and work can be improved. In addition, when filling the foamed heat insulating material, these shapes are intertwined with the foamed heat insulating material, acting as an anchor structure, and the bonding strength of the door outer plate, the base, and the wedge is improved.

(14) Since the stepped cutout of the door outer plate is narrowed in a U-shape, the trim is gradually guided and mounted when the trim is inserted. Since the clearance of the trim step-shaped notch is small, it is possible to prevent leakage of the foamed heat insulating material.

(15) As another embodiment, the trim is changed from an E-shaped cross section to an S-shaped cross section, so that when the trim is inserted into and engaged with the body, the fitting between the body and the trim becomes U-shaped. This eliminates the need for a trim body hole 13 _e for trim and a body claw 11 _e shown in FIG. 4 to be described later, thereby reducing mold costs.

(16) When the refrigerator user operates the handle, there is no sharp corner so that the safety can be improved without damaging the fingers and nails.
