The present invention relates to a refrigerator.

The refrigerator is a household appliance for storing food in a low temperature state, and may be classified into a top mount refrigerator, a bottom freezer refrigerator, and a side-by-side refrigerator according to the location of the refrigerator and freezer.

In particular, in the bottom freezer refrigerator, a refrigerator compartment is disposed above the freezer compartment, and the refrigerator compartment is opened and closed by a pair of refrigerator compartment doors. In addition, the pair of refrigerating compartment doors are hinged to the left and right edges of the refrigerating compartment, respectively, so as to be rotatable.

In addition, each of the pair of refrigeration compartment doors may be defined as a fixed end to which the hinge is coupled and a free end that is an opposite side end of the fixed end. In addition, when the pair of refrigerator compartment doors are closed, the free ends of the pair of refrigerator compartment doors are disposed adjacent to each other.

In addition, since there is no vertical partition wall in which the rear edges of the free ends of the pair of refrigerating compartment doors are in close contact with each other inside the refrigerating compartment, a large amount of cold air loss may occur in this part.

According to the present invention, while maintaining the size and shape of the filler body 210, it is possible to increase the thickness of the heat insulating member 213.

In the case of the present invention, in order to increase the thickness of the heat insulating member 213, a communication hole 214a is formed in the existing frame 214, and the heat insulating member 213 faces the portion where the communication hole 214a is formed. Increased the thickness.

In the case of FIG. 11, a cross-sectional view of a section of a filler body provided with a frame 214 having a communication hole 214a is illustrated, and in FIG. 12, a filler with a frame 214 ′ not formed in the communication hole It is a view showing a section for each section of the body.

11 and 12 (a) is a cross-sectional view taken along A-A 'of Figure 8, (b) is a cross-sectional view taken along B-B' of Figure 8, (c) is C of Figure 8 It is a cross-sectional view cut along -C '.

11, when the communication hole 214a is formed in the frame 214, the insulating member 213 protrudes through the communication hole 214a, and the thickness T1 of the insulating member 213 is protruded. Can be increased.

In detail, when the communication hole 214a is formed in the frame 214, at least a portion of the heat insulating member 213 may protrude through the communication hole 214, and thus, the thickness T1 of the heat insulating member 213 ) Can be increased. As described above, when the thickness of the heat insulating member 213 is increased, in a state in which a pair of doors are closed, heat insulating properties between a pair of doors and between a pair of doors and an interior can be improved.

On the other hand, when a communication hole is not formed in the frame 214 '(see FIG. 12), the thickness T2 of the heat insulating member 213' is limited by the flat frame 214 ', and accordingly, the heat insulating member It is difficult to increase the thickness of (213 ').

13 and 14 is a graph comparing the surface temperature of the filler according to the presence or absence of a change in the insulation structure of the filler body.

The graphs shown in FIGS. 13 and 14 are graphs in which the filler body shown in FIG. 11 and the filler body shown in FIG. 12 are mounted in a refrigerator, and temperature measurement results are measured at the upper and lower sides of the filler body, respectively. .

At this time, the temperature measured in the state in which the filler body (see FIG. 11) in which the thickness T1 of the heat insulating member 213 is increased is applied to the refrigerator by forming a communication hole 214a in the frame 214 is "after change" The temperature measured in the state in which the filler body (see FIG. 12) in which the thickness T2 of the heat insulating member 213 'is not increased because the communication hole is not formed in the frame 214' is applied to the refrigerator. "Before change".

In addition, the temperature measurement was made at a point spaced 240 mm from the top of the filler, and at a point spaced 560 mm from the top, respectively. The results of comparison of temperature measurements at are shown in 14.

13 to 14, when the communication hole 214a is formed in the frame 214, and the thickness of the heat insulating member 213 is increased, after the change, the thickness of the heat insulating member 213 'is increased. It can be seen that the measured temperature is lower than that of the "before change" which has not been made.

That is, as the communication hole 214a is formed in the frame 214, and the thickness of the heat insulating member 213 increases, the heat insulating property between the pair of doors and between the pair of doors and the interior is improved when the pair of doors is closed. It can be confirmed that it is more advantageous for maintaining the temperature inside the furnace.

In addition, the dew condensation phenomenon is reduced in the boundary area facing the free ends of the pair of doors, and the operation rate of the heater provided to prevent the dew condensation of the door is reduced, so that the amount of power consumed by the operation of the heater can be reduced. .
