ていた。 In a conventional refrigerator, as shown in Fig. 1a and b, there is a gap 4 between the freezer compartment door 1 and the refrigerator compartment door 2 for attaching a hinge 3 that pivotally supports these doors 1 and 2. A front part 8 of a partition plate 7 that partitions a freezer compartment 5 and a refrigerator compartment 6 is exposed. Since air stagnates in this gap 4, dew tends to occur, and dew forms on the lower end of the door 1, the upper end of the door 2, and the front part 8. Until now, as shown in FIG. There is a refrigerant condensation pipe 9 on the back side of the front part 8,
9 was installed to heat this area and prevent dew formation.

Depending on the position of the condensing pipes 9, 9, the heat may instead enter the inside of the refrigerator, creating a heat load.

る。 The present invention was made to eliminate the above-mentioned drawbacks, and as shown in the embodiment shown in Fig. 3, the front part is bulged to form a protrusion, and a condensation pipe is housed inside the protrusion. . In FIG. 3, the same parts as in FIGS. 1 and 2 are denoted by the same reference numerals. In Figure 3, 1
Reference numeral 1 denotes a protrusion formed by expanding the front surface. This protrusion 11 corresponds to the gap 4 formed between the doors 1 and 2.
The condensing pipe 9 is inscribed and fitted into the front side of the inside of this protrusion 11 . This condensing pipe 9 is fitted into the protrusion 11 and is pressed against the front surface of the protrusion 11 by a heat insulating material 10 . With this configuration, the gap 4
Since the space is smaller and the amount of stagnant air is reduced, and this space is efficiently heated by the heat from the pipe 9, no condensation occurs. In particular, since the heat insulating material 10 is foamed with the condensing pipe 9 housed within the protrusion 11 when assembling the refrigerator, the pipe 9 is positioned within the protrusion 11 regardless of dimensional accuracy or the foaming state of the heat insulating material 10. As a result, the front surface portion 8 is always in contact with the front surface portion 8, and the defective rate due to prevention of dew formation can be reduced. In addition, since the pipe 9 is located farther away from each of the compartments 5 and 6 of the refrigerator, the amount of heat entering into the refrigerator is reduced, and the heat load can be reduced.

ができる。 As described above, according to the present invention, in a refrigerator in which a condensation pipe for preventing condensation is disposed on the front part of a partition plate that partitions adjacent chambers, a condensation pipe for preventing condensation from forming on the front part of the partition plate protrudes between the doors that seal the adjacent chambers. Since a condensation pipe is provided on the front side of the inside of this protrusion and is fitted inwardly to the protrusion, the gap formed between the doors is reduced and the condensation is retained in the space. By reducing the amount of air and by the heating effect of the condensing pipe, it is possible to prevent dew from forming on the front surface of the partition plate. In this case, since the condensation pipe is inscribed and fitted inside the protrusion, the condensation pipe does not need to be fixed with special fixing means, and there is no possibility of misalignment, and errors when assembling the refrigerator. Regardless, the condensing pipe can be reliably pressed against the inner front side of the protrusion, and the heating effect of the condensing pipe can be reliably exerted. In addition, since the condensation pipe is located on the front side of the protrusion, the distance between the condensation pipe and the inside of the refrigerator can be increased.
It is possible to suppress the heat from the condensing pipe from entering the refrigerator.
