Description

[Detailed Description of the Invention] The present invention relates to a refrigerator having an improved support structure for the end of a dew-proof pipe.

In conventional refrigerators, the end of the anti-condensation pipe was fitted into a recess formed on the back side of the bottom plate frame of the outer box, and then fixed with tape, so the fixing strength was weak and it was difficult to assemble the pipe. This has the disadvantage that the drawer dimensions at the end of the dew-proof pipe become uneven, making it difficult to connect to the compressor and condenser, making it difficult to assemble the refrigerator. There was a drawback that separate parts were required.

The present invention was developed in view of the above circumstances, and its purpose is to provide a refrigerator that improves the assembly of the refrigerator by increasing the fixing strength of the end of the dew-proof pipe and eliminates the need for separate parts such as tape. There is something to do.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

Reference numeral 1 denotes an outer box of the refrigerator body, which has openings 2 and 3 for a freezer compartment and a refrigerator compartment formed on the front side, and a bottom plate frame 4 attached to the lower part.

Although not shown in the drawings, each inner box that will form a freezer compartment and a refrigerator compartment in a later process is installed inside this outer box 1, and a heat insulating wall is formed between the outer box 1 and each inner box using, for example, foamed urethane. It is something.

Reference numeral 5 indicates a flange 6 formed on the front surface of the outer box 1 and openings 2 and 3 on the inner surface side of a front plate 7 disposed between the openings 2 and 3.
This is a dew-proof pipe arranged along the peripheral edge of the bottom plate frame 4, which is oriented rearward along the upper surface of the bottom plate frame 4 and has both ends bent downward.

8, 8 is a flange portion 9 formed on the back side of the bottom plate frame 4.
These are two concave parts formed in the middle, and these have a convex part 10 in the middle.
and have a predetermined interval.

Reference numeral 11.11 denotes a tongue piece provided above and adjacent to the concave parts 8, 8, which are formed by punching out a part of the flange part 9, and are connected to the protrusion 10 and the tongue piece 11.
The vertical distance A is set to be larger than the outer diameter dimension d of the dew-proof pipe 5, and the distance B between the tip of the tongue portion 11 and the convex portion 10 when viewed from above as shown in FIG. It is set smaller than the dimension d.

Then, both ends of the dew-proof pipe 5 are fit into the recesses 8, 8, respectively, while tilting as shown by two-dot chain lines in FIG. After setting, the tip of the tongue piece 1.1.11 is pressed forward to bend the tongue piece 11.11 along the dew prevention pipe 5, thereby creating a recess q, 85. , 8, both ends of the dew-proof pipe 5 are positioned.

According to the above-mentioned embodiment having such a configuration, both ends of the dew prevention pipe 5 are firmly positioned on the flange portion 9, so that the both ends of the dew prevention pipe 5 will not be misaligned during assembly of the refrigerator. Since the drawer size of the dew-proof pipe 5 is made constant, the ease of assembling the refrigerator can be greatly improved.

Further, there is no need for separate fixing parts such as tape, and since the tongue portion 11 and the recessed portion 8 are manufactured by press molding on the bottom plate frame 4, there is no need for additional parts. do not have.

As shown in FIG. 5, a notch groove 12 is formed in the middle part of the tongue piece 11, and the portion on the tip side of the notch groove 12 is bent at a right angle to position and fix the dew-proof pipe 5. You may also do this.

As explained above, the present invention has a structure in which the end of the dew-proof pipe is positioned and fixed by the tongue piece formed on the bottom plate frame of the outer box, so the fixing strength of the end of the dew-proof pipe is increased and the refrigerator This has the practical effect of improving assembly efficiency and eliminating the need for separate parts such as tape.
