The present invention relates to a refrigerator, and more particularly, to a refrigerator having improved structures of a cold air duct and a cold air distribution member.

In general, a refrigerator has a relatively low temperature freezer compartment and a relatively high temperature refrigerating compartment, and includes a refrigerating system for cooling these freezer compartments and storage stored in the refrigerating compartment. The refrigeration system of the refrigerator comprises a compressor for compressing the refrigerant, a condenser for condensing the refrigerant from the compressor, and an evaporator for evaporating the refrigerant from the condenser to generate cold air supplied to the freezing compartment and the refrigerating compartment, respectively.

5 is a side cross-sectional view of a conventional refrigerator. As shown in this drawing, the conventional refrigerator includes a main cabinet 101 in which upper and lower compartments 110 and a lower freezing chamber 111 are formed in an up and down direction, and are installed in front of the main cabinet 101 and have an upper refrigerator compartment ( 110 and a refrigerating chamber door 108 and a freezing chamber door 109 for rotating and opening the front openings of the lower freezing chamber 111, respectively.

The main cabinet 101 has an outer casing 103 which forms the exterior of the refrigerator, an upper casing chamber 110 which is arranged at an inner side of the outer casing 103 with a gap between the outer casing 103 and the filling material, and is isolated from each other. It consists of an inner casing 105 to form the lower freezing chamber 111.

A plurality of article storage spaces are formed in the upper refrigerator compartment 110 and the lower freezer compartment 111 by a plurality of shelves 107 arranged to have a predetermined distance from each other in the vertical direction, and the rear side of the lower refrigerator compartment 111. In the region, an evaporator cover 117 is provided which forms a cold air flow passage 118 so that the installation space of the evaporator 116 and the cold air from the evaporator 116 can be evenly supplied to each storage space in the lower freezing chamber 111. In the upper region of the evaporator 116, a blowing fan 119 is provided to blow cold air generated by the evaporator 116 to the lower freezing chamber 111 and the upper refrigerating chamber 110.

On the other hand, the rear wall surface of the upper refrigerating chamber 110 is provided with a cold air distribution member 130 for receiving the cool air from the evaporator 116 and evenly supplied to each storage space in the upper refrigerating chamber 110, the lower freezing chamber 111 And a cold air guiding passage 112 in the foam filling space in the rear region of the inner casing 105 forming the upper refrigerating chamber 110 so that cool air from the evaporator 116 can be guided into the upper refrigerating chamber 110. The cold air duct 113 and the cold air circulation duct 115 which guide the air which cooled the upper refrigerating chamber 110 to the evaporator 116 are provided.

The cold air distribution member 130 includes a spacer 131 of a heat insulating material disposed from the lower region in front of the rear wall surface of the upper refrigerating chamber 110 to the upper region, and a distribution cover 133 disposed to surround the front surface of the spacer 131.

The distribution cover 133 is provided with a plurality of cold air discharge holes 136a corresponding to the cold air discharge ports 139 of the spacer 131.

The cold air duct 113 is disposed to extend from the cold air flow passage 118 of the evaporator cover 117 toward the lower portion of the cold air distribution passage 135 of the cold air distribution member 130, and guides the cold air in the cold air duct 113. A damping device 114 is provided to block and open the flow path 112 to adjust the supply amount of the cold air supplied from the evaporator 116 to the upper refrigerating chamber 110. The cold air circulation duct 115 includes the upper refrigerating chamber 110. It is arranged so as to face the evaporator 116 from the lower wall surface area of the rear wall.

By this configuration, the cold air generated in the evaporator 116 is blown to the cold air flow passage 118 of the evaporator cover 117 by the blowing force of the blower fan 119, and then a part of the cold air is evaporator cover 117 After the cold air discharge hole (136b) of the lower refrigeration chamber 111 is supplied into the inside, and another part of the cold air is supplied to the cold air distribution member 130 of the upper refrigerating chamber 110 through the cold air duct 113, The cold air supplied to the upper refrigerating chamber 110 through the cold air discharge holes 136a formed in the distribution member 130, and the cold air supplied to the lower refrigerating chamber 111 and the upper refrigerating chamber 110, respectively, are cooled after Returning to the evaporator 116 through the circulation duct 115, the heat exchange is again performed in the evaporator 116, and then the circulation process supplied to the lower freezing chamber 111 and the upper refrigerating chamber 110 is repeated.

At this time, the cold air supplied to the upper refrigerating chamber 110 flows into the lower region of the cold air distribution member 130 through the cold air duct 113, and then moves to the upper region of the cold air distribution channel 135 while the cold air distribution passage ( The cold air discharge port 139 of the 135 and the cold air discharge hole 136a of the distribution cover 133 are supplied to each storage space in the upper refrigerating chamber 110.

However, in such a conventional refrigerator, since a cold air distribution member for receiving cold air from the cold air duct and distributing it to the respective storage spaces inside the upper refrigerator compartment is disposed in front of the rear wall of the upper refrigerator compartment, the volume of the upper refrigerator compartment is determined by the cold air distribution member. The problem of decreasing the installation area is generated.

In addition, since the cold air duct guiding the cold air from the evaporator is connected to the lower portion of the cold air distribution channel of the cold air distribution member, and the cold air distribution channel is formed from the lower side of the upper refrigerator compartment to the upper portion, the cold air introduced into the cold air distribution member. Flowing from the lower region of the upper refrigerator compartment toward the upper region is supplied to each storage space in the upper refrigerator compartment. As a result, relatively low cooling air is not effectively supplied to the storage space formed in the upper region of the upper refrigerating chamber, thereby causing a problem in that cooling in the upper refrigerating chamber is not uniformly performed.

Accordingly, an object of the present invention is to provide a refrigerator in which a plurality of storage spaces formed inside the refrigerator compartment can be uniformly cooled while increasing the volume of the refrigerator compartment.
