Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a connecting part for connecting panels in a T-shape.

As shown in FIG. 1, for example, when a refrigerator-freezer 3 having a freezer compartment 1 and a refrigerator compartment 2 is constructed with a heat insulating panel, the outer wall 4 of the freezer compartment 1 is covered with a relatively thick heat insulating panel (for example, 1007Ir!IL thickness). On the other hand, the outer wall 5 of the refrigerator compartment 2 is constructed with a relatively thin (for example, 4017EI71 thickness) insulation panel, and the partition wall 6 that partitions both compartments is constructed with a relatively thick (lOor
Ir1! The partition wall 6 is connected to both outer walls 4 and 5 in a T-shape.

One way to perform such a T-shaped connection is to use the second method.
As shown in the figure, an L-shaped connecting panel 9 is used to connect the respective heat insulating panels 7 and 8 forming the outer wall 4 and partition wall 6 of the freezer compartment 1 at right angles to each other.

This L-shaped connecting panel 9 has frame members 9A and 9B for connecting to the heat insulation panels 7 and 8, respectively.
The heat insulating panel 10 constituting the outer wall 5 of the refrigerator compartment 2 is simply butted against the back surface of the L-shaped connecting panel 9, an angle member 11 is applied, and the panel is connected and fixed with bolts or the like (not shown).

Such a structure requires a lot of time to assemble, and
Heat loss due to poor butt alignment has the disadvantage of increasing heat loss through the surface plate 9C of the L-shaped connecting panel 9 that continues from the inner surface of the refrigerator compartment 2 to the outer surface of the freezer compartment 1. Used only when holding.

As another method, as shown in FIG.
．． 11A of frame materials for connecting with 8 and 10, respectively;
A T-shaped connecting panel 11 with IIB and IIC is used.

Although such a T-shaped connecting panel 11 does not cause problems with heat loss, it has a manufacturing drawback in that it is difficult to form the upright portion 11C in the T-shape at right angles, making it difficult to obtain a long structure. There is also the disadvantage that storage occupies an undue amount of space during transportation.

The object of the present invention is to provide a structure for a T-shaped panel connection that does not have these drawbacks.

To this end, the present invention has a configuration in which the base part of the T-shape is formed as a single heat insulating panel member, and the heat insulating panel that becomes the upright part of the T-shape is connected in a direction perpendicular to this heat insulating panel member. A frame material is provided on one side of the base heat insulating panel to connect the upright heat insulating panels, and this frame material has engagement grooves at different heights on both edges. The frame member is characterized in that the engaging groove is engaged with the surface plate on one side to provide a required panel thickness on both sides of the frame member.

An embodiment of the present invention will be described with reference to FIG.
The structure of this connecting portion is such that a heat insulating panel 20 as one member constitutes a T-shaped base portion, and another heat insulating panel 21 is detachably connected as an upright portion.

(Of course, it is possible to connect a heat insulating panel 21 having the same structure as the heat insulating panel 20.

) The heat insulating panel 20 consists of one surface plate 22 on one side, and two surface plates 23 and 24 on the other side, and a frame member 25 is provided so as to connect these surface plates 23 and 24.

The frame member 26 of the heat insulating panel 21 is positioned and fixed with respect to the frame member 25 by inserting the fitting members 27 into the respective fitting grooves 25A and 26A, so that it can be connected to the heat insulating panel 20 in a right angle direction. It has become.

Additionally, when a connection is made, caulking material 28 is applied to form a thermally insulating seal.

The frame material 25 has an engagement groove 25B with the surface plate 23 and the surface plate 2.
4 are provided at different height positions, so that the thickness given by the surface plate 22.23 on one side of the frame material 25 and the thickness given by the surface plate 22.24 on the other side. are made differently.

That is, T in the configuration of the refrigerator-freezer 3 shown in FIG.
When adopted as a connecting part of the shape, the frame material 29 provided at the edge of the one side' can be connected to the heat insulating panel 7 (FIG. 2) constituting the outer wall 4 of the freezer compartment 1, and the frame member 29 on the other side can be connected to the heat insulating panel 7 (Fig. The thickness of each material 30 is set so that the material 30 can be connected to the heat insulating panel 10 (FIG. 2) constituting the outer wall 5 of the refrigerator compartment 2.

In this case, a heat insulating panel 21 is connected to a frame member 25 as a heat insulating panel 8 (FIG. 2) constituting the partition wall 6.

FIG. 5 shows how the heat insulating panel 20 is manufactured, with the top plates 23 and 24 facing down, and a support plate 31 placed on the bottom surface of the top plate 24.
The frame material 29 is held down by holding plates 32, 32 from above and below, and polyurethane is foamed through small holes 33 formed in the frame material 29.

With this structure, the work of connecting them into a T-shape can be easily done in the same way as the usual work of connecting insulation panels together, and the insulation panel 21, which is the upright part, is the same as the insulation panel 20, which is the base part. Since the frame 25 and the fitting member 27 fit together with high accuracy and can sufficiently withstand external forces in the thickness direction, there is no need to use angle materials or the like.

In addition, no special processing is required for any of the surface plates, and they can be handled as flat panel members at all times, making them convenient for storage and transportation. It's not necessary.

Furthermore, according to this connection configuration, internal and external insulation can be reliably achieved by the insulating panel corresponding to the base part, which is an integral member, and insulation can also be reliably performed on both sides of the insulating panel corresponding to the upright part, so that it can be used even under severe temperature conditions. It can also be easily applied to refrigerators and freezers.
