Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator door manufacturing method and a refrigerator door manufactured using the same.

[0002]

2. Description of the Related Art A conventional refrigerator door will be described with reference to the drawings. 4 to 6 are views showing a conventional technique, FIG. 4 is an external perspective view of a refrigerator, FIG. 5 is a cross-sectional view taken along line XX of FIG. 4, and FIG. 6 is a state after filling a foam insulation material in FIG. It is sectional drawing explaining.

The refrigerator door 10 comprises a front door assembly 11 and a rear door assembly 21. The front door assembly 11 includes a press-made steel plate door plate 12, a resin-molded door cap 13 and a door sash 14. The front door assembly 11 is assembled as follows. That is, the door plate 12 is fitted into the door cap 13, and the door sash 14 is fitted therein. After the upper surface of the door sash 14 is pressed and sealed by a foaming jig (not shown), a foam heat insulating material 15 such as urethane foam is injected and filled between the door plate 12 and the door sash 14 through a nozzle 16. Both 17 and 18 are guide ribs. The door rear assembly 21 includes a door back 22 and a plurality of door pockets 23 attached to the door back 22, and is attached to the door front assembly 11 filled with the foam heat insulating material 15.

Since the above-mentioned door cap 13 is made of resin, warpage and distortion occur. Therefore, when the door plate 12 is fitted into the door cap 13, a portion that does not follow the door cap 13 may be generated, and a gap may be formed. When the gap is generated, when the foam heat insulating material 15 is filled, the foam heat insulating material 15 leaks.Therefore, a seal tape (not shown) is attached between the door cap 13 and the door plate 12 to prevent this leak. It has become. However, the sticking work of the sealing tape is not effective unless it is completely sealed, which is troublesome and troublesome.

In order to eliminate the above-mentioned problems, as shown in FIG. 5, a hot melt agent 19 having a high temperature of 120 to 130 ° C. is injected into the mating surface 13A of the door cap 13 and the door plate 12 and sealed. The seal work is simplified. The hot melt agent 19 is mainly composed of an olefin resin,
It contains a synthetic resin adhesion-imparting agent, a paraffin wax, an antiaging agent, and an antioxidant as auxiliary components, and effectively acts as a sealant.

[0006]

However, since the hot melt agent 19 described above has a high temperature of 120 to 130 ° C., the door cap 13, which is a resin molded product, is heated and deformed, so that the warp or distortion of the door cap 13 occurs. It can grow. Then, when the foam heat insulating material 15 was injected, there was a problem that the foam heat insulating material 15A leaked from the gap. The present invention has been made in view of the above circumstances, and provides a method for manufacturing a refrigerator door in which foamed insulating material does not leak out between a door cap and a door plate, and a refrigerator door manufactured using the same. Is intended.

[0007]

A method of manufacturing a refrigerator door according to the present invention is a method of manufacturing a refrigerator door which seals a foamed heat insulating material leaking from between a door cap and a door plate fitted in the door cap. There is a groove formed on the surface of the door cap that fits with the door plate at right angles to the direction in which the door plate is fitted, and the groove is filled with a thermosetting sealant, and then the door plate is fitted onto the door cap. It is characterized by having been put in. A refrigerator door is a refrigerator door that seals foam insulation that leaks from between the door cap and the door plate fitted in the door cap, and the fitting direction of the door plate on the mating surface of the door cap with the door plate. It is characterized in that it is provided with a recessed groove which is orthogonal to the above and has an opening at the upper side, and the recessed groove is filled with a thermosetting sealing material.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 is an exploded perspective view of the refrigerator door, and FIG.
FIG. 3 is a cross-sectional view taken along line XX, and FIG. 3 is a cross-sectional view illustrating a state after filling the foamed heat insulating material in FIG. The same parts as those in the conventional technique are designated by the same reference numerals.

The refrigerator door 30 of the present invention comprises a front door assembly 31 and a rear door assembly 21, and the front door assembly 31 includes a door plate 12, a door cap 32 and a door sash 14. The door cap 32 is molded of resin, and a recessed groove 33 is provided in a fitting surface 32A into which the door plate 12 is fitted. The recessed groove 33 is provided in the longitudinal direction of the door cap 32 at substantially the entire length orthogonal to the insertion direction of the door plate 12, and is open at the upper side. Thermosetting sealing material 40 is provided in the groove 33.
Is filled.

Next, the procedure for assembling the front door assembly 31 will be described together with its operation. The groove 33 of the door cap 32 is filled with the sealing material 40. Insert the door plate 12 into the mating surface 32A of the door cap 32. A seal material 40 is fitted into the gap between the door cap 32 and the door plate 12 in the fitting direction to provide a seal. Furthermore, the sealing material 40 spreads in the longitudinal direction of the door cap 32, that is, in the entire width direction, and the entire surface is sealed. Since the sealing material 40 does not require a high temperature unlike the conventional hot melt agent, the door cap 32 is not thermally deformed. The door sash 14 is fitted and the foam heat insulating material 15 is filled. Since the door cap 32 and the door plate 12 are sealed,
No foam leaks. After that, attach the rear door assembly 21 to the front door assembly 31 and attach the door packing (not shown) to the refrigerator door.
30 is assembled.

[0011]

As described above, the method of manufacturing a refrigerator door according to the present invention and the refrigerator door manufactured by using the same.
30 is a door cap 32 provided with a recessed groove 33 which is orthogonal to the fitting direction of the door plate 12 and has an upper opening, and the recessed groove 33 is filled with a thermosetting sealant 40, and then the door plate 12 is attached to the door cap 32. I am trying to fit it in. Therefore, the door cap 32 is completely sealed without being thermally deformed by the seal material 40, so that the foamed heat insulating material 15 does not leak and the appearance is good. Further, since the sealing work does not require any labor, productivity can be improved.
