Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator cabinet, and more particularly to a connecting device for integrally forming a partition wall member that divides a main body into a plurality of storage compartments with an inner box.

Generally, when an inner box is formed by vacuum forming by placing a plastic sheet in advance with a partition wall member in a vacuum forming mold and heating and softening it, the plastic sheet wraps around the partition wall member and is released from the vacuum forming mold. This makes it possible to manufacture an inner box to which the partition wall member is fixed.

At this time, in order to more firmly adhere the plastic sheet and the partition wall member, when forming the partition wall member by injection molding etc. on the side edge of the partition wall member that contacts the inner wall of the inner box, a protruding strip 7 is integrally formed. However, as shown in Figure 2, the cross-sectional shape of the refrigerator cabinet consists of a side wall 3a of the storage compartment for storing food, etc., and a door body 4 that opens and closes the front opening of the refrigerator.
The inner plate 5 of is housed.

A step equal to the width of the inner box is provided with the wall 3b of the throat portion.

Providing the above-mentioned protrusions on the side edge of the partition wall member facing the wall 3b of the throat portion means that the flange 3 on the front periphery of the inner box
Since it protrudes outward from the width C, the cutting die for trimming the flange after forming the inner box by vacuum forming not only becomes very complicated and expensive, but also the outer box 2. There are also problems in assembling when fitting the inner box 3 to the inner box 3.

The present invention was made in view of such problems, and the illustrated embodiment will be described below. Reference numerals 1 to 7 indicate the same parts as in FIGS. 1 to 3, and 8 indicates the throat portion of the inner box of the partition wall member 6. A recessed portion 10 is formed by incorporating a heat insulating material 9 to be housed in the partition wall member into a hole formed when the partition wall member is molded by injection molding or the like in the abutting side edge portion.

Next, as shown in FIG. 4, a partition wall member 6 having a concave portion 10 on the side edge facing the inner box throat portion is set in a vacuum mold 12, and molding is performed by a well-known vacuum forming method. Once started, the plastic sheet 11 is placed in the vacuum mold 12.
At the same time, the side edge of the partition wall member corresponding to the wall where food is stored is formed along the shape of the recess 10 as shown in FIG. 7, and is cooled and solidified in this state. As with the protruding strips 7 provided in the section, the plastic sheet and the partition wall member are firmly fixed to each other.

As described above, this invention strengthens the adhesion between the partition wall member and the inner box without providing a protruding strip on the side edge of the partition wall member, so that the outer circumference of the inner box can be removed after forming the inner box. This has various effects, such as being easy to make and eliminating problems when fitting the inner box to the outer box.

Claims (1)

[Scope of utility model registration request] In a vacuum forming mold for forming an inner box constituting a refrigerator main body by a vacuum forming method, a partition wall member that divides the main body into a plurality of storage chambers is set in advance, and then the inner box is formed. A recess is formed on the side wall of the partition wall member that contacts the inner box by the outer wall of the partition wall member and the heat insulating material stored inside, and a part of the inner box material is held in this recess along the shape during molding. A refrigerator cabinet characterized in that the partition wall member is formed within the inner box.
