Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

For reference, the cooling chamber described in the claims below refers to the freezer compartment and the refrigerating compartment. Therefore, if only one of the freezer compartment or the refrigerating chamber is formed by using the example of the small refrigerator to convey the spirit of the present invention, it will be expressed as a "cooling chamber".

However, this embodiment will be described in detail with reference to the present invention using the refrigerator of FIG. Therefore, in the following description, the term "cooling chamber" will be omitted, and this will be described in detail as "freezing chamber" and "refrigeration chamber", respectively.

1 is a perspective view of a refrigerator according to the present invention, and FIG. 2 is a schematic enlarged view of a hot pipe region of the refrigerator shown in FIG. 1. As shown in these figures, the refrigerator according to the present invention is rotatably coupled to the cabinet 10 and the front side of the cabinet 10 formed with the freezing compartment 20 and the refrigerating compartment 30 in the up and down direction, respectively. (20) and a freezer compartment door 25 and a refrigerating compartment door 35 for rotating and opening the refrigerating compartment 30.

The freezer compartment shelf 21 is provided in the freezer compartment 20, and the some refrigerator compartment shelf 31 is provided also in the refrigerating compartment 30 along the up-down direction. The vegetable compartment 32 is provided in the lower part of the refrigerator compartment shelf 31. As shown in FIG.

The cabinet 10, which is a part that forms the exterior of the refrigerator, includes a freezer compartment part 11, which forms a freezer compartment 20, a refrigerator compartment cabinet part 12, which forms a refrigerator compartment 30, and a freezer compartment, It consists of an intermediate cabinet part 13 arranged between the refrigerator compartment cabinet parts 11 and 12. As shown in FIG.

One side of the inner surface of the freezer compartment 25 and the refrigerating compartment door 35 is equipped with an upper gasket 26 and a lower gasket 36 which prevents the cooling air from the freezer compartment 20 and the refrigerating compartment 30 to be discharged to the outside. . In addition, the upper and lower gaskets 26 and 36 and the upper magnet 27 and the lower magnetic gaskets 26 and 36 magnetically contact and release contact, respectively, on one side of the intermediate cabinet portion 13. The magnet 37 is provided.

On the other hand, as described above, since the internal temperature of the freezer compartment 20 and the refrigerating compartment 30 is significantly lower than the outdoor temperature, the freezer compartment 20 and the refrigerating compartment door 35 are provided around the gasket. Dew is generated by the difference between the temperature in the refrigerating chamber 30 and the external room temperature.

In particular, dew condensation occurs more easily at the lower end of the freezing compartment 20, which is significantly different from the outdoor temperature than the refrigerating compartment 30 side. Thus, as in the prior art, by providing a predetermined hot pipe 40 in the intermediate cabinet portion 13 to generate heat around the gasket provided in the freezing chamber 25 and the refrigerating chamber door 35, the dew condensation phenomenon is prevented.

As shown in Fig. 2, the intermediate cabinet portion 13 is formed on the front face portion 13a and the front face portion 13a in which the magnets 27 and 37 are arranged according to their positions, and is integrally formed on the front face portion 13a. At both ends of the), each has an extending portion 13b extending laterally to the front portion 13a. That is, the intermediate cabinet portion 13 forms a substantially rectangular structure.

When the intermediate cabinet portion 13 is formed in a substantially rectangular structure, the intermediate cabinet portion 113 (see FIG. 3) is formed by using the body portion 114 (see FIG. 3) and the front cover 115 (see FIG. 3). Compared with the prior art, the manufacturing cost is reduced, as well as the manufacturing process is much easier to improve the productivity.

In addition, since the assembly tolerance can naturally remove the moxibustion H (see FIG. 3) generated between the body portion 114 (see FIG. 3) and the front cover 115 (see FIG. 3), the moxibustion (H (See FIG. 3), it is possible to effectively prevent the dew condensation phenomenon.

The inner surface of the front portion 13a of the intermediate cabinet portion 13 adjacent to the magnet is provided with a hot pipe 40 that generates heat to the upper and lower gaskets 26 and 36. The hot pipe 40 serves to prevent dew condensation that may occur in the upper and lower gaskets 26 and 36 by generating heat by using high-temperature, high-pressure compressed heat compressed by a compressor (not shown) installed in a refrigerator. In particular, the dew condensation phenomenon that can be formed on the lower end of the freezer compartment 20 that is significantly different from the outdoor temperature than the refrigerator compartment 30 side is prevented. However, a separate power source may be connected to the hot pipe 40 to generate heat by itself.

In the related art, the amount of heat transferred from the hot pipe 140 (see FIG. 3) differs depending on the degree of adhesion between the hot pipe 140 (see FIG. 3) and the intermediate front plate 115a (see FIG. 3), thereby limiting dew condensation. Was followed.

However, in the present invention, the hot pipe 40 is brought into close contact with the front part 13a by using the separate contact member 50 to closely contact the hot pipe 40 disposed on the inner surface of the front part 13a of the intermediate cabinet part 13. Most of the heat from the heat is not lost and is directed to the upper and lower magnets 27 and 37 and the upper and lower gaskets 26 and 36 through the intermediate cabinet portion 13.

The contact member 50 has a contact portion 50a which is in surface contact with the rear surface of the front portion 13a, and a seating portion which is bent in multiple stages toward the rear in any one region of the contact portion 50a to seat and support the hot pipe 40. It consists of 50b.

At this time, the contact member 50 is preferably made of a conductive iron plate so that the upper and lower magnets (27, 37) can be in magnetic contact. When the contact portion 50a is to be coupled to the rear surface of the front portion 13a, it may be attached using an adhesive or the like, but the tape is simply used in the present invention.

By this structure, the contact part 50a of the contact member 50 is moved to the front part 13a of the intermediate cabinet part 13, with the hot pipe 40 seated on each seating part 50b of the contact member 50. The hot pipe 40 is brought into surface contact with the front portion 13a by surface contact with the rear surface. Then, the space in the intermediate cabinet portion 13 is foamed with a heat insulator C to complete the intermediate cabinet portion 13.

When the compressor in the refrigerator operates in such a state, the high-temperature, high-pressure compressed heat compressed by the compressor is transferred to the hot pipe 40, and the hot pipe 40 generates heat. As such, when the hot pipe 40 generates heat, the hot pipe 40 is transferred to the front portion 13a of the intermediate cabinet portion 13 without leakage of heat, and then the upper and lower magnets 27 and 37, and the upper and lower gaskets 26 and 36, respectively. You will be directed to.

Therefore, the dew condensation which may occur in the freezing chamber door 25 and the refrigerating chamber door 35 can be effectively prevented. Of course, as described above, it is possible to effectively prevent the dew condensation phenomenon in the region of the freezer compartment 25 which is much different from the outdoor temperature.

In addition, by forming the intermediate cabinet portion 13 integrally, eliminating the slack (H, see FIG. 3) generated in the conventional refrigerator intermediate cabinet portion 113 (see FIG. 3), while reducing manufacturing costs, productivity is improved and the appearance is improved. It can raise the righteousness.

As described above, according to the present invention, there is provided a refrigerator capable of more effectively preventing dew condensation that may occur around the freezer compartment and the refrigerating compartment door.

In addition, according to the present invention, by manufacturing the intermediate cabinet portion integrally without the body portion and the front cover to eliminate the moxibustion generated between the body portion and the front cover while reducing the manufacturing cost to improve productivity and enhance the appearance of the product One refrigerator is provided.
