断熱材である現場発泡ポリウレタン発泡時の作業
性の改善に関するものである。[Detailed description of the invention] This invention relates to a refrigerator box in which the refrigerator box is divided into upper and lower parts by an insulating partition wall to form a freezer compartment and a refrigerator compartment, and the refrigerator box is cooled by circulating cold air with a fan. In particular, it relates to improving workability when foaming in-place polyurethane foam, which is a heat insulating material.

強度を向上している。 Generally, in this type of refrigerator box, as shown in Figure 1, the partition wall that divides the upper part of the inner box into a freezing compartment and the lower part into a refrigerator compartment is integrally formed by vacuum forming a resin plate such as ABS. . In-situ foamed polyurethane is filled between the inner and outer boxes to form a heat insulating layer and improve the strength of the box.

度に保持するようにしている。 However, in recent years, due to reductions in material costs, the steel plates that make up the outer box have become thinner, reducing the strength of the outer box itself. By cutting out the front flange side, which is the non-duct-forming part of the foam insulation molded material such as Styrofoam, and filling this cavity with the polyurethane, the box strength is maintained at the same level as conventional products. ing.

A food placing portion is formed by recessing the front flange at an appropriate distance from the front flange, and a plurality of ribs are arranged to prevent stickiness.

う欠点があつた。 Generally, when filling with polyurethane, the periphery of the outer box is supported by an outer jig, and the inner surface of the inner box is supported by an inner jig in order to withstand foaming pressure. However, since the food placement section is in an undercut shape, it cannot be supported by an internal jig.
There was a drawback that workability during polyurethane foaming was poor because the placement jig, which is a separate part, was placed on the food placement section in advance.

Reference numeral 1 denotes a refrigerator body, in which an inner box 3 is inserted into an outer box 2 made of a steel plate, and an inner box 3 is integrally formed with a partition wall 6 that partitions the upper side into a freezing compartment 4 and the lower side into a refrigerator compartment 5 by ABS vacuum forming. Reference numeral 10 denotes a food placing part formed by recessing the freezer compartment floor 7, which is the upper wall of the partition wall 6, with an appropriate distance from the front flange 8, and is provided with a plurality of ribs 9 to prevent stickiness. has been done.

It has been inserted. 13 is a sealing tape that seals the partition cavity 1
4 and the front surface 15 of the foamed heat insulating molded material are sealed. Reference numeral 16 is filled with in-situ foamed polyurethane between the inner box 3 and the outer box 2 to form a heat insulating layer.

等実用的効果を有するものである。 As described above, this invention extends the front surface of the foamed heat-insulating molded material to the flat part of the front surface of the inner partition so that the foaming pressure during foaming is not applied to the undercut-shaped food placement section. It becomes possible to eliminate the placement jig of the placement section. In addition, in the past, because a partition cavity was provided up to the food placement area, it was difficult to seal the rib surface to prevent stickiness, and urethane leaked from around the rib surface, causing unevenness on the food placement surface. Since this invention seals the flat part of the partition, it has practical effects such as improved sealing performance and stable quality.
