Description

[Detailed Description of the Invention] The present invention relates to a refrigerator door, and particularly to an improved structure of a refrigerator door having an article outlet.

In general, a refrigerator door equipped with an article outlet includes, for example, a freezer compartment door equipped with an ice chip extraction device, a refrigerator compartment door equipped with a cold water pouring device, and the like.

When manufacturing such refrigerator doors, foaming the insulation material on-site requires special jigs and equipment, as well as tapes and sealants to seal the insulation material, and the work is difficult and labor intensive. Since a considerable number of them are required, there is a drawback that the cost is high.

The present invention was developed in view of these points.

The present invention will be explained below with reference to the drawings showing one embodiment thereof.

Reference numeral 1 denotes the main body of the refrigerator, which has a freezer compartment door 2 and a refrigerator compartment door 3 on the front.

4 is an auxiliary door provided at the ice piece outlet 5 of the freezer compartment door 2.

Therefore, the freezer compartment door 2 has an outer plate 6, an inner plate 7, and both plates 6, 7.
It consists of a heat insulating material 8 filled in between.

Note that 9 is a gasket provided on the periphery of the back surface of the freezer compartment door 2.

The ice piece outlet 5 is constituted by openings 10.11 formed opposite to each other in the outer plate 6 and inner plate 7, and a decorative frame 12 connecting the two openings 10.11.

A rib 13 that surrounds the opening 11 of the inner plate 7 is formed on the back surface of the decorative frame 12.

FIG. 3 shows one step in manufacturing such a freezer compartment door 2, in which the inner plate 7 is not attached and no heat insulating material is injected or foamed.

The ribs 13 are in contact with the foaming jig 14, so that a sealed space 15 is formed by the outer panel 0, the decorative panel 12, the ribs 13, and the foaming jig 14.

In this state, polyurethane or the like may be injected into the closed space 15 and foamed.

As described above, according to the configuration of the above embodiment, the rib 13
By forming this, it is possible to easily seal with the foaming jig 14, making it possible to manufacture the freezer compartment door 2 with extremely good workability, reducing manufacturing costs, and
The ribs 13 increase the strength near the ice piece outlet 5.

As is clear from the above description, the refrigerator door of the present invention has an outer panel and a white panel with opposing openings, and a decorative frame is provided to connect both openings to form an article outlet. In the case where an auxiliary door or the like is provided at the outlet, ribs are formed on the back side of the decorative board to surround the opening of the inner board and to come into contact with the foaming jig when foaming is injected into the outer board. It is characterized in that the space formed by the ribs, the decorative frame, the outer panel, and the foaming jig is filled with the foaming heat insulating material, and the strength of the vicinity of the article outlet can be increased by the ribs. Of course, this rib can be used to easily seal the gap between the jig and the jig, making it easy to fill the insulation material using the on-site foaming method, which simplifies the process of connecting the inner plate to the decorative frame. As a result, excellent effects such as a refrigerator door without leakage of insulation material can be obtained at a low cost.
