A heat transfer part 300 for transferring dew from the heat source outside the refrigerator body 110 to the circumference of the groove bar 200 to remove the dew formed around the groove bar 200, and the heat insulation part 600 for insulating the heat transfer part. 5 and 6).

The front door of the refrigerator main body 110 is provided with two-door doors 120 that rotates to open and close the refrigerating area and the freezing area. One or both of the doors 120 are provided with the home bar 200 for selectively opening and closing the freezing area or the refrigerating area to the outside. Here, the groove bar 200 may be adopted to open and close rotation up and down.

Here, the home bar 200 is composed of a home bar door 210 that opens and closes a part of the door 120, and a home bar frame 220 that forms an opening opened and closed by the home bar door 210, and the home bar 200. The perimeter may be an area formed along the groove bar frame 220.

And, although not shown in the figure, the heat transfer part 300 is a pipe body that surrounds the circumference of the groove bar 200, both ends are located in the heat source, the core material 320 is installed on the inner circumference, The inside of the pipe body is filled with a working fluid which evaporates due to the heat transferred from the outside to form a vacuum.

Here, the heat transfer part 300 which is a heat pipe as described above has a predetermined length, and both ends thereof are located at the lower end of the refrigerator main body 110. Preferably, the refrigerator 120 may be installed at a lower end of the door 120 installed in the refrigerator main body 110. Accordingly, the heat source is located in the lower portion of the door 120 of the lower portion of the refrigerator body 110. In particular, since the heat source is located under the door 120 positioned in front of the refrigerator main body 110, the heat source may form a predetermined distance from the machine room located at the rear side lower end of the refrigerator main body 110.

In addition, portions except the both ends of the heat transfer part 300 may be positioned upward along the inner surface of the door 120 to be in close contact with the circumference of the groove bar 200 to surround the circumference of the groove bar 200. .

In particular, the circumference of the groove bar 200 in contact with the heat transfer part 300 is made of a plastic material. In addition, the inner part of the refrigerator main body 110 or the door 120 in contact with the heat transfer part 300 is made of metal. Here, the inner part of the refrigerator body 110 in contact with the heat transfer part 300 may be the inner part of the door 120.

In addition, the heat insulation part 600 may be made of polyurethane, and may enclose a portion of the home bar 200 except a portion that is in contact with the circumference of the home bar 200 and the outer surface of the refrigerator body 110.

5 illustrates a state in which the heat transfer part 300 at the home bar 200 is surrounded by the heat insulation part 600.

The circumference of the groove bar 200 is formed of a plastic material of ABS resin, and the heat transfer part 300, which is a heat pipe, is attached to the circumferential surface of the groove bar 200. The heat insulating part 600 is made of a foam such as polyurethane, and is foamed to cover the circumferential surface of the groove bar 200 and the outer circumference of the heat transfer part 300 to cover the heat transfer part 300.

Accordingly, the heat flow flowing in the heat transfer part 300 may be easily insulated by the heat insulation part 600, so that heat transfer efficiency may not be reduced.

6 illustrates a state in which the heat transfer part 300 in the inner part of the door 120, which is the inner part of the refrigerator body 110, is surrounded by the heat insulating part 600.

The inner part of the door 120 is made of a metal material. In addition, the heat transfer part 300 for transferring the heat generated from the lower part of the refrigerator main body 110 to the circumferential side of the home bar 200 is installed in close contact with the inner side of the door 120. In addition, the heat insulating part 600 as described above forms a foamed state to cover the heat transfer part 300 at the inner side of the door 120.

By being insulated by the heat insulating part 600, the heat transfer efficiency in the process of transferring heat from the heat source P3 to the circumference of the groove bar 200 may be increased. Conversely, heat transfer loss at the inner side of the door 120 can be efficiently reduced.

Therefore, referring to FIG. 7, it can be seen that the temperature inside the home bar 200 is less than the dew point temperature without any power supply when the heat pipe, that is, the heat transfer part 300 is used.

Here, the heat transfer part 300 will be described in more detail.

When the heat transfer part 300 is once applied with heat from the outside, the volatile working fluid filled inside the vacuum state is evaporated, and the evaporated working fluid is raised upward. This raised position may be a circumferential position of the home bar 200. That is, it is raised from the P3 position to the P1 position through the P2 position.

In addition, the working fluid positioned around the home bar 200 is cooled by receiving heat from the inside of the home bar, and again descends to the other end by its own gravity to transfer heat. That is, it returns to P1.P2, P3 position.

In general, a machine room in which a condenser 400 or a compressor for dissipating a predetermined heat during a refrigeration cycle is installed at a lower rear end of the refrigerator main body 110. The heat is discharged to the outside of the refrigerator main body by a device such as a fan (not shown).

Accordingly, the lower portion of the refrigerator main body 110 may be formed above a predetermined temperature by heat emitted by a device such as the condenser 400 or a compressor.

At this time, both ends of the heat transfer unit 300 in the present invention is installed at the lower end of the door 120 that is the lower portion of the refrigerator body 110 serves as a heat source.

In one end of the heat transfer part 300 which receives heat from the heat source, the working fluid 320 evaporates, and the evaporated working fluid 320 forms a temperature transferred from the heat source to form a circumferential position of the home bar 200. Is raised. Thus, the circumference of the home bar 200 is heated due to the transmitted temperature. Accordingly, dew condensation may be prevented by the temperature heated around the groove bar 200 in a state where the dew point temperature is raised. In addition, the working fluid 320 that transfers heat to the refrigerator at the circumferential position of the home bar 200 is lowered below a predetermined temperature and lowered to the other end of the heat transfer part due to its own gravity.

Accordingly, in the present invention, by transferring the waste heat formed in the lower portion of the refrigerator main body 110 around the groove bar 200, dew condensation around the groove bar 200 can be effectively prevented.

On the other hand, as shown in Figure 8, the refrigerator main body 100 according to the present invention may be further formed with a flow path 410 for guiding heat emitted from the condenser 400 to the heat source.

Accordingly, even when the condenser 400 is not installed at the lower end of the refrigerator main body 110, the same flow path is connected to a portion where the condenser 400 and the heat source are positioned in the refrigerator main body 110, thereby providing a condenser ( Heat dissipated from 400 may be transferred to the heat source so that a predetermined heat is formed in the heat source.

In addition, as shown in FIG. 9, at the lower end of the refrigerator main body 110, an auxiliary fan 500 for guiding heat emitted from the condenser 400 installed in the refrigerator main body 110 to the heat source is further included. Can be installed.

Therefore, in the present invention, by forming the forced convection to the heat source using the auxiliary fan 500 to the heat emitted from the condenser 400, the waste heat emitted from the condenser 400 can be transferred to the heat source more efficiently than natural convection. Can be.

In addition, as shown in FIG. 10, the condenser 400 may be installed at a lower end of the refrigerator body 110. Therefore, since the heat dissipated from the condenser 400 forms an area of both ends of the heat transfer part 300 installed at the lower end of the door 120 at the lower end of the refrigerator body 110, that is, the same layer as the heat source. Convection allows easy transfer to the heat source.

In addition, an auxiliary fan 500 may be further installed at a lower end of the refrigerator main body 110 so as to be positioned at the side of the condenser 400. Accordingly, since the heat emitted from the condenser 400 can be transferred to the heat source through the forced blowing, it is possible to constantly provide heat of a constant temperature to the heat source.

In addition, the condenser 400 may further include a fan (not shown) for discharging the generated condensation heat to the outside.

In this case, the blowing direction of the fan may be directed toward the lower part of the refrigerator main body 110 in which the heat source is located.

In this case, the condensation heat is forced to be blown to the lower portion of the refrigerator main body 110, so that the heat of condensation can be efficiently transferred to the heat source.
