[Detailed description of the invention]

[0001]

The present invention relates to an electric refrigerator door,
In particular, the present invention relates to a device for preventing a gap between a joint portion between a door body and a corner cap.

[0002]

2. Description of the Related Art A conventional door for an electric refrigerator is shown in FIGS.
As shown in FIG. 3, the left and right ends of the surface-treated steel sheet with the four corners cut out are bent rearward so as to have curved portions 3 at both ends of the front face to form left and right side faces 4, and the end faces are further bent inward. bending to form a flange portion and right angle bent to form a vertical side 5 of the upper and lower ends to the rear, further a door body 2 to form a flange portion by bending the end surface on the inside, the door body 2
The door inner plate 6 by plastic molding attached to the flange portion of the back side, in order to close the raw Ji that gap on both sides of the upper and lower sides 5 of the door body 2, a corner cap 7, etc., which fit so as to cover from above It is configured. Although a urethane foam resin stock solution is injected between these wall plates and foamed and solidified inside to form a heat insulating wall, even if there is a slight gap between the joint portion between the door body 2 and the corner cap 7 , the urethane foam may be formed. Since a large pressing force is applied due to the expansion and hardening of the resin, the unfoamed liquid of the urethane resin may leak from the gap. However, the junction of the corner cap 7 and the door body 2 which has been used conventionally, as principal part cross-sectional view of a conventional electric refrigerator door shown in Figure 3, the curved portion on both sides of the door body 2
End of 3 with front and left side, a flange portion provided on the periphery of the corner cap 7, the joint because of being sandwiched between the plurality of ribs 9 provided relative to the flange portion of the adhesion However, since the upper and lower side surfaces 5 of the door main body 2 are merely stopped by the claw portions 12 provided on the corner cap 7 , a gap is easily generated in the joint portion, and the unfoamed urethane resin undiluted solution is formed from the gap. Leakage and the corner cap 7 floats from the door body 2 .

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides an electric refrigerator door in which a gap is not formed by bringing the upper and lower surfaces of a door body into close contact with a joint portion of a corner cap. Things.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problem, the present invention forms left and right side surfaces by bending left and right both ends of a plate material having four corners cut out, and further folds the end surfaces inward. A door body with upper and lower sides bent at right angles to form upper and lower sides, and the end faces bent inward to form flanges, and both sides of the upper and lower sides of the door body. in the refrigerator door which is composed of a corner cap or the like for closing the raw Ji that gap, the corner cap, front and one same corner cap
A downward flange provided on the peripheral edge of the side
A plurality of ribs provided on the back surface opposite to the
It is set up on the back side where the rib is provided, and the thin part is
The flange portion and the rib
Between the left and right sides and the corner cap.
While receiving the upper and lower side surfaces on the inner surface of the
The support in which a predetermined portion is bent downward by the thin portion.
The crimping is performed by the tip of the portion .

[0005]

With the above construction, in the refrigerator door according to the present invention, a support portion having a thin portion formed substantially at the center is erected on the surface provided with the rib on the back side of the corner cap. Since the portion is bent from the thin portion and the upper and lower side surfaces of the door main body are pressure-bonded at the front end of the support portion, the joining portion is in close contact and no gap is generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of an essential part of an embodiment of an electric refrigerator door according to the present invention, and FIG. 2 is a sectional view of an essential part of an embodiment of the electric refrigerator door according to the present invention. In the drawing, 1 is a door for an electric refrigerator, 2 is a door body, and the left and right ends of a surface-treated steel plate with four corners cut out are bent rearward so as to have curved portions 3 on both sides of the front surface to form left and right side surfaces 4. Further, the end face is bent inward to form a flange portion, and the upper and lower ends are bent rearward at right angles to form upper and lower side surfaces 5,
Further, the end face is bent inward to form a flange portion.
A door inner plate 6 made of plastic is attached to a flange formed on the back side of the door main body 2. In order to close gaps formed on both sides of the upper and lower side surfaces 5 of the door body 2,
A corner cap 7 is fitted so as to cover from above, and a urethane foam stock solution is injected between these wall plates and foamed and solidified inside to form a heat insulating wall. Further, a downward flange 8 is provided on the front edge and one side edge of the corner cap 7. Front and left and right side surfaces 4 having curved portions 3 at both ends of body 2
A support portion 10 having a thin portion 11 at a substantially central portion is erected on the surface provided with the rib 9 on the back side of the corner cap, and the support portion 10 is bent from the thin portion 11, A predetermined portion of the upper and lower surfaces 5 of the door main body 2 is crimped at the tip of the support portion 10.

[0007]

As described above, in the refrigerator door according to the present invention, a support portion having a thin portion formed substantially at the center is erected on the surface provided with the rib on the back side of the corner cap. Since the supporting part is bent from the thin part and the upper and lower side surfaces of the door body are pressure-bonded at the tip of the supporting part, the joint part is in close contact and there is no gap. Can be prevented. Further, since the corner cap can be inserted only in one direction, workability is good.
