Hereinafter, embodiments of a refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a first embodiment of a refrigerator according to the present invention, and FIG. 2 is a sectional view of a door in a first embodiment of a refrigerator according to the present invention.

Referring to FIGS. 1 and 2, a refrigerator compartment 3 and a freezer compartment are provided in the refrigerator main body 1. The refrigerating chamber (3) and the freezing chamber are divided into upper and lower portions where food is stored. The refrigerating chamber 3 and the freezing chamber are selectively opened and closed by two refrigerating chamber doors 5 and 6 and one freezing chamber door 7, respectively.

On the other hand, an ice making chamber 83 is provided on the rear surface of the refrigerating chamber door 5 (hereinafter, referred to as 'door' for the sake of convenience) on the left side of the refrigerating chamber doors 5 and 6. The ice making chamber 83 is partitioned from the refrigerating chamber 3 by an ice-making housing 81 and an ice-making chamber door 82. The ice making housing 81 is opened to the rear of the door 5 and the ice making chamber door 82 is installed at one side of the ice making housing 81 to selectively open and close the ice making chamber 83. An ice maker 84 for producing ice and an ice bin 85 for storing ice produced by the ice maker 84 are installed in the ice making chamber 83. [

A first gasket 86 and a second gasket 87 are provided in the ice making chamber door 82. The lower portion of the first gasket 86 is located at a position apart from the rim of the ice making chamber door 82 and the remaining portion is located along the rim of the ice making chamber door 82. The second gasket 87 is located at a position corresponding to the inside of the first gasket 86. The first gasket 86 is in close contact with the ice bin 85 when the ice making chamber door 82 is closed. The second gasket 87 is in close contact with the ice making housing 81 when the ice making chamber door 82 is closed. At this time, the first gasket 86 is arranged to form a closed curve along the inner surface of the ice-making chamber door 82, which overlaps the ice-making housing 81 in the longitudinal direction. The second gasket 87 is arranged to form a closed curve along the inner side edge of the ice making chamber door 82 which overlaps with the ice bin 85 in the front and rear direction. Therefore, the space between the ice making chamber door 82 and the ice bin 85 is separated from the ice making chamber 83 by the second gasket 87. That is, a heat insulating layer 88 is provided between the ice making chamber door 82 and the ice bin 85 by the second gasket 87. Here, the first gasket 86 and the second gasket 87 may be formed of an elastic material, and an air layer may be provided therein.

The refrigerator includes a compressor (not shown) provided at one side of the main body 1 to compress the refrigerant, an evaporator (not shown) disposed at the rear of the main body 1 to form a cool air, A blowing fan (not shown) for allowing the cool air formed through the evaporator to be supplied to the refrigerating chamber 3 and the freezing chamber, and a cool air blown by the blowing fan to be supplied to the refrigerating chamber 3, the freezing chamber and the ice making chamber 83 (Not shown). At this time, the duct may be disposed along the inner front surface portion, the side surface portion, or the rear surface portion of the main body 1. Since the duct connected to the ice making chamber 83 must be rotatable in order to open and close the door 5, the duct may be intermittently connected in a separated state, or may be partly freely bent, .

A dispenser (not shown) is provided on the front surface of the door 5. The dispenser is for the user to draw water and / or ice without opening the door (5).

Hereinafter, the operation of the first embodiment of the refrigerator according to the present invention will be described in detail.

First, when the operation of the refrigerator is started, the refrigerant and the air inside the main body 1 are circulated by the compressor and the blowing fan, respectively. In detail, the air in the main body 1 is cooled by heat exchange with the refrigerant in the process of passing through the evaporator. The cooled air flows into the freezing chamber through the duct.

Some or all of the cool air flowing into the freezing chamber or the cool air discharged from the freezing chamber flows into the refrigerating chamber 3 and the ice making chamber 83. At this time, the amount of cool air flowing into the refrigerating chamber (3) can be adjusted by various methods such as a method of changing the number of times the flow path is opened or closed for a predetermined time, or a method of providing a damper on the flow path. Since the ice making chamber 83 is required to generate ice, the air flowing into the ice making chamber 83 continuously flows into the ice making chamber 83 so that the temperature of the ice making chamber 83 approaches the temperature of the freezing chamber 83.

Therefore, as time passes, the refrigerating chamber (3) is maintained at the temperature of the image, and the ice making chamber (83) is kept at the subzero temperature. That is, since the temperature of the refrigerating chamber 3 is relatively higher than the temperature of the ice making chamber 83, heat is transferred from the refrigerating chamber 3 to the ice making chamber 83.

A first gasket 86 is provided between the ice making chamber door 82 and the ice making housing 81 so that the refrigerating chamber 3 and the ice making chamber 83 are separated from each other. A direct air flow can be prevented between the first and second openings 83.

A second gasket 87 is provided between the ice making chamber door 82 and the ice bin 85 so that the ice making chamber door 82 and the ice bin 85 corresponding to the inside of the second gasket 87, 85 are isolated, the air between the ice making chamber door 82 and the ice bin 85 is stagnated. When the air between the ice making chamber door 82 and the ice bin 85 is stagnated, the cool air inside the ice making chamber 83 flows between the ice making chamber door 82 and the ice bin 85 The convective heat transfer coefficient for determining the heat transfer amount between the ice making chamber door 82 and the cold air adjacent to the ice making chamber door 82 is reduced. Compared with the case where the cold air inside the ice making chamber 83 flows between the ice making chamber door 82 and the ice making device by the second gasket 87, The heat transfer amount between the cold air adjacent to the ice chamber door 82 is further reduced and the heat insulating effect between the refrigerating chamber 3 and the ice making chamber 83 can be further increased.

Accordingly, melting of the ice generated and stored in the ice making chamber 83 can be prevented.

Since the heat transfer phenomenon between the refrigerating chamber 3 and the ice making chamber 83 is minimized, the temperature inside the refrigerating chamber 3 adjacent to the ice making chamber door 82 can be maintained more uniformly as a whole. Therefore, the food and beverage stored in the refrigerating chamber 3 can be stored in a refrigerated state with a more uniform performance regardless of the position.

Further, the temperature difference between the outer surface of the ice-making chamber door 82 and the inside of the refrigerating chamber 3 can be further reduced, thereby minimizing the generation of condensed water on the outer surface of the ice-making chamber door 82 have.

Hereinafter, a second embodiment of the refrigerator according to the present invention will be described in detail. The present embodiment differs from the first embodiment in that a plurality of gaskets for further partitioning the space between the ice-making chamber door and the ice bin corresponding to the inside of the second gasket are further provided.

4 is a perspective view of a refrigerator according to a second embodiment of the present invention.

Referring to FIG. 4, in the second embodiment of the refrigerator according to the present invention, a plurality of gaskets 97 for partitioning the space between the ice-making chamber door 92 and the ice bin 95 corresponding to the inside of the second gasket 97, (99). In detail, on the one hand, the plurality of gaskets 99 are arranged laterally so as to connect one side and the other side of the second gasket 97. The space between the ice making chamber door 92 and the ice bin 95 corresponding to the inside of the second gasket 97 is formed by the plurality of gaskets 99 on the other hand, (98). At this time, the plurality of gaskets 99 may be integrally formed with the second gasket 97.

According to the present embodiment, since the heat insulating layer 98 provided between the ice making chamber door 92 and the ice bin 95 is partitioned into a plurality of spaces, the space in which the air can flow in the heat insulating layer 98 is further reduced do. That is, when the heat insulating layer 98 is divided into a plurality of heat insulating layers 98, the tendency of the air inside the heat insulating layer 98 to flow is further reduced as compared with the case where the heat insulating layer 98 is formed as a single body. Accordingly, the convective heat transfer coefficient for determining the amount of heat transferred between the ice making chamber door 92 and the cold air adjacent to the ice making chamber door 92 is further reduced.

Particularly, since the plurality of gaskets 99 are arranged in the lateral direction, that is, the heat insulating layer 98 is divided into a plurality of longitudinal portions, the natural convection, which can be formed in the heat insulating layer 98, Can be prevented. Therefore, the heat insulation effect between the ice making chamber door 92 and the ice making chamber door 92, that is, between the refrigerating chamber 3 and the ice making chamber 93 can be further increased.

It will be apparent to those skilled in the art that many other modifications and variations are possible in light of the above teachings and the scope of the present invention should be construed on the basis of the appended claims will be.

For example, a heat insulating material may be further provided in a space between the ice making chamber doors 82 and 92 and the ice bins 85 and 95. The first gaskets 86 and 96 and the second gaskets 87 and 97 are formed as integral gaskets extending from the position of the first gasket 86.96 to the position of the second gaskets 87 and 97 . Also, the second gaskets 87 and 97 may be provided in the ice bins 85 and 95. In addition, the method in which the gaskets 86, 87, 96, 97, 99 are fixed to the ice making chamber doors 82, 92 or the ice bins 85, 95 is a method of being attached by an adhesive, Or a method of being fastened by a fastening means such as a screw or the like.
