Benefits of technology

[0048]According to the refrigerator according to this embodiment, the thickness of the heat insulation layer for a freezing compartment is formed to be thin whereas the thickness of the heat insulation layer for a refrigerating compartment is formed to be relatively thick in a barrier in which an evaporator is accommodated, thereby minimizing a phenomenon in which the refrigerating compartment is excessively cooled.
[0049]Furthermore, the evaporator is located on the freezing compartment, thereby minimizing the whole thickness of the barrier and, at the same time, maintaining the heat insulation performance of the refrigerating compartment.
[0050]In addition, a fan motor assembly accommodating part is additionally depressed, thereby securing a space which allows the cold air of the evaporator to be introduced into a blowing fan and, therefore, improving the flow performance of the cold air.
[0051]In addition, the fan motor assembly accommodating part and a cold air flowing part are formed to be depressed in the barrier, thereby making the flow of the cold air within the barrier smooth, and, at the same time, making the entire structure of the barrier simple.
[0052]Furthermore, the evaporator is accommodated in the barrier, thereby increasing the interior volume of the refrigerator.
[0053]Furthermore, when an ice making unit is mounted in the freezing compartment door, the length of the cold air passage connected to an ice making duct is shorten, thereby decreasing the loss of cold air.

Problems solved by technology

The side by side-type refrigerator among such refrigerators is configured to have an evaporator mounted on the rear side of the refrigerating compartment and / or the freezing compartment to supply cold air to the refrigerating compartment and the freezing compartment, but there is a problem in that the interior volume of the refrigerator is decreased by the space occupied by the mounting of the evaporator.
However, in such a refrigerator, the heat insulation of the barrier on which the evaporator and the cold air circulation fan are disposed is not made, so that there is a problem in that a refrigerating compartment is excessively cooled.
Furthermore, there is a problem in that the circulation of the cold air flowing in a narrow space within the barrier is not smooth.

first embodiment

[0082]FIG. 1 is an exterior perspective view of a refrigerator according to the present invention, and FIG. 2 is a front perspective view showing the internal structure of the refrigerator.

[0083]Referring to FIGS. 1 and 2, the exterior shape of the refrigerator 1 according to an embodiment of the present invention is formed by a cabinet 10 defining a storage space and a door 20 to open and close the storage space.

[0084]The cabinet 10 is divided into left and right sides by a barrier 100 to define a refrigerating compartment 40 and a freezing compartment 30 respectively. The refrigerating compartment 40 and the freezing compartment 30 are configured to have a plurality of drawers and shelves therewithin and to preserve various foods therein. The door 20 is composed of a refrigerating compartment door 24 and a freezing compartment door 22 for respectively opening and closing the refrigerating compartment 40 and the freezing compartment 30. Furthermore, the refrigerating compartment do...

second embodiment

[0150]Referring to FIGS. 13 to 15, in the refrigerator 1 according to this embodiment, the ice compartment 60 is provided in the freezing compartment door 22 as in the It should be noted that the cold air rising along the cold air passage 230 of the barrier 100 be delivered to the ice maker 61 by a cold air guide duct 70 formed on the ceiling of the freezing compartment 30.

[0151]Specifically, the cold air guide duct 70 is formed on the ceiling of the freezing compartment 30, and has a cold air outlet 701 on the front surface thereof. Furthermore, the ice making unit 60 includes an ice maker 61, an ice maker cover 64 sounding the ice maker 61 and an ice bin 63 disposed on the lower side of the ice maker 61. Furthermore, the lower end of the ice bin 63 is disposed on the upper surface of the discharge duct 23.

[0152]In addition, the front surface of the cold air guide duct 70 and the upper surface of the ice maker cover 64 may be formed to be tilted at a predetermined angle. That is, ...

fourth embodiment

[0155]FIG. 16 is an exploded perspective view of a barrier included in a refrigerator which shows the configuration of a freezing compartment, and

[0156]FIG. 17 is a cross-sectional view taken along line IV-IV of FIG. 16.

[0157]Referring to FIGS. 16 and 17, the barrier 100 is formed to be elongated up and down inside the cabinet 10, and an evaporator 110 and a blowing unit 130 for a freezing compartment are mounted therewithin.

[0158]The external shape of the barrier 100 is defined by a casing 150 that defines the internal spaces of the refrigerating compartment 40 and the freezing compartment 30 and a heat insulator 300 is foamed and filled within the casing 150. The heat insulator 300 is filled evenly throughout the internal space of the barrier 100.

[0159]Meanwhile, a depression part 200 for a freezing compartment is formed on the left side surface of the barrier 100, that is, the surface exposed to cold air from the freezing compartment 30. Furthermore, the evaporator 110 and the b...

Abstract

A refrigerator includes a cabinet having a storage space; a barrier to divide the storage space into a freezing compartment and a refrigerating compartment, filled with a heat insulator, and having a depression part formed on one side surface thereof; an evaporator accommodated in a part of the depression part; a blowing unit accommodated in another part of the depression part corresponding to a upper side of the evaporator; a barrier cover to shield the depression part by covering one side surface of the barrier. The depression part includes an evaporator accommodating part to accommodate the evaporator, a blowing unit accommodating part configured to accommodate the blowing unit, and a cold air passage extended from the blowing unit accommodating part to allow the cold air to be guided into the freezing compartment and to refrigerating compartment. The blowing unit accommodating part is depressed greater than the evaporator accommodating part.

Description

TECHNICAL FIELD[0001]The present invention relates to a refrigerator and a control method thereof.BACKGROUND ART[0002]Generally, a refrigerator is consumer electronics that can store food at low temperature. The refrigerator uses cool air generated by heat exchange with a refrigerant circulating a freezing cycle to cool the storage space, such that it is configured to store the stored food at an optimum state.[0003]The refrigerator tends to increase more and more in its size and to have multi-functions as dietary life changes and users' taste is diversified, and the structure thereof is also diversified according to the configuration of the storage space.[0004]Generally, the storage space inside the refrigerator is divided by a barrier to form a refrigerating compartment and a freezing compartment, and the structure thereof may be variously configured according to the arrangement of the refrigerating compartment and the freezing compartment.[0005]In particular, a side by side-type r...
