Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a top-opening type freezer whose inner box is molded from synthetic resin.

Conventional technology Conventionally, in a top-opening type freezer, a cooling pipe is installed inside the inner box wall on the side of the insulating box body to serve as an evaporator, and a reinforcing material is glued to the bottom side of the inner box on the side of the insulating box body to improve the strength of the bottom surface. consideration is being given to obtaining

An example of the conventional freezer mentioned above will be described below with reference to FIGS. 4 to 6. 1 is a freezer main body, and is composed of an outer box 2 with an open top, an inner box 3 made of synthetic resin with an open top and built into the outer box 2, and a heat insulating material 4 filled between the outer box 2 and the inner box 3. ing. Reference numeral 5 denotes a cooling pipe, which is attached to the wall of the inner box 3 with a thermally conductive member 6 attached thereto. Reference numeral 7 denotes a bottom reinforcing material on a flat plate, and the outer periphery of the bottom reinforcing material 7 and the inner box 3 are fixed in advance with tape 8 before filling with the heat insulating material 4.

In this configuration, the bottom reinforcing material 7 attached to the bottom of the inner box 3 is pressed against the inner box 3 by the foaming pressure of the heat insulating material 4, thereby preventing the bottom of the inner box 3 from being damaged by objects falling from the top of the freezer. are doing.

Problems to be Solved by the Invention However, with the above structure, when the heat insulating material 4 is foamed, the tape 9 attached to the outer periphery of the inner box 3 and the bottom reinforcing material 7 tends to wrinkle or sag, causing the inner box 3 and the bottom surface to become wrinkled. The insulation material penetrates between the reinforcing materials 70, and due to temperature changes and the impact of falling stored items, etc.
This may cause peeling or swelling, which poses a quality problem.

In addition, since the cooler can only cool from the inside side of the refrigerator, its cooling capacity is small and there are performance problems.

In view of the above-mentioned problems, the present invention provides a structure that improves the adhesion between the synthetic resin inner box and the bottom reinforcing material and cools the inner box from the bottom surface as well.

Means for Solving the Problems In order to solve the above problems, the present invention attaches a cooler to the inner box made of synthetic resin and the bottom reinforcing material using a thermally conductive material, and also attaches the cooler to the inner box and the bottom reinforcing material. Double-sided tape is pasted between the linen surface reinforcement material.

Function According to the above-described structure of the present invention, the inner box made of synthetic resin, the bottom reinforcing material, and the cooler are attached with a thermally conductive member, and double-sided tape is attached between the inner box, the bottom box, and the bottom reinforcing material. , the cooler not only cools the inner box but also cools the bottom reinforcing material via the thermally conductive member. Further, when the bottom reinforcing material is cooled, the bottom of the inner box is cooled through the double-sided tape, thereby providing the freezer with a high cooling capacity.

Furthermore, the double-sided tape has the effect of improving the adhesion between the inner box and the bottom reinforcing material in order to prevent damage to the inner box due to objects falling from above.

Example Below, an example of the present invention is shown in Figs. 1, 2, and 3.
This will be explained with reference to the figures.

1 is the freezer body, 2 is the outer surface, 3 is the inner box, 4 is the insulation material, 5
1 is a cooling pipe, and 7 is a bottom reinforcing material, which are the same as those of the conventional example, so a detailed explanation thereof will be omitted.

Reference numeral 9 denotes a thermally conductive member which fixes the cooling pipe 5 to the inner box 3 and also fixes it to the bottom reinforcing member 7. 1o is stuck between the bottom reinforcing material 7 and the inner box 3 using double-sided tape so that no gap is left between them.

The cooling structure of the synthetic resin inner box configured as described above will be explained.

The inner box 3 made of synthetic resin has its side surfaces directly cooled by a cooling pipe 8 and indirectly via a thermally conductive member 9, and the bottom reinforcing material 7 and double-sided tape 1o are cooled from the thermally conductive member 9. The bottom surface of the inner box 3 is cooled through the inner box 3.

Therefore, the freezer main body 1 cools the inner box 3 from the side and bottom surfaces and has a large cooling capacity.

Further, the adhesive force of the double-sided tape 1o prevents dents and peeling of the bottom reinforcing material due to the impact of the ring of objects falling from the top onto the inner box 3, ensuring high adhesion.

Effects of the Invention As described above, the present invention has been achieved by pasting double-sided tape between the bottom reinforcing material installed at the bottom of the synthetic resin inner box and the inner box, and by attaching double-sided tape between the cooling pipe, the inner box, and the bottom reinforcing material. By attaching the inner box with a thermally conductive member, cooling can be performed from the side and bottom surfaces of the inner box, and the inner box has a high cooling capacity.
