Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator. More particularly, the present invention relates to a refrigerator in which cold air can be smoothly supplied to a door basket disposed below the door of the vegetable compartment and the refrigerator compartment 121.

1 is a longitudinal sectional view of a conventional refrigerator. As shown in the drawing, the refrigerator includes a main body 101 having a freezer compartment 111 and a refrigerating compartment 121 formed therebetween with partitions 102 interposed therebetween, and a front surface of the freezer compartment 111 and the refrigerating compartment 121. A freezing chamber door 112 and a refrigerating chamber door 122 hinged to the main body 101 to open and close the opening.

A compressor 107 is provided in the lower rear region of the main body 101 to compress the refrigerant, and the rear region of the freezer compartment 111 is disposed parallel to the rear wall of the main body 101 so that air can be circulated. The shroud 115 is formed so as to form a circulation flow path. An evaporator 113 is installed inside the circulation passage to perform a cooling action as the refrigerant evaporates, and an upper side of the evaporator 113 is cooled to promote the flow of air so that air can be exchanged while passing through the evaporator 113. The fan 119 is provided.

In the front region of the shroud 115 along the front and rear directions of the freezing chamber 111, grill members 117 having a plurality of discharge ports 118 are provided to be spaced apart from each other by a predetermined distance. In the freezing chamber 111 and the refrigerating chamber 121, the freezer compartment return passage 103 and the refrigerating chamber return passage 105 are formed so that the air is returned to the circulation passage and cooled.

Meanwhile, a plurality of shelves 123 spaced apart from each other in the up and down direction and supporting foods are installed in the refrigerating chamber 121, and a lower portion of the vegetable compartment tray forming a vegetable compartment for storing vegetables and fruits ( 129 is provided.

A refrigeration cold air duct having a plurality of cold air discharge ports 127 communicating with the freezing compartment 111 and spaced apart from each other along the vertical direction in the rear region of the refrigerating compartment 121 to discharge the cold air provided from the freezing compartment 111 to the refrigerating compartment 121. 125 is provided, and a plurality of door baskets 124 are coupled to the inner plate surface of the refrigerating chamber door 122 to be spaced apart from each other in the vertical direction.

By such a configuration, the refrigerant compressed by the compressor 107 is introduced into the evaporator 113 through a condenser and a capillary tube (not shown), and the refrigerant introduced into the evaporator 113 has a cooling action of evaporating while absorbing the latent heat of the surroundings. Will be performed.

When the cooling fan 119 is driven, air in the freezer compartment 111 and the refrigerating compartment 121 is circulated through the freezer compartment return passage 103 and the refrigerator compartment return passage 105 formed in communication with the circulation passage in the partition 102. It flows into the flow path and is cooled while passing through the evaporator 113. Some of the cooled air is discharged to the freezing chamber 111 through a discharge port formed in the grill member 117, a part flows into the refrigerating chamber 121, and the refrigerating chamber 121 through the cold air discharge port 127 of the refrigeration cold air duct 125. To be discharged.

However, in such a conventional refrigerator, the vegetable chamber tray 129 for storing and storing vegetables and fruits has an upwardly open cylindrical shape, and the upper opening is disposed to be adjacent to the shelf 123 to cool vegetables and fruits. Indirect cooling without direct contact, when a large amount of vegetables or fruits at room temperature inside the vegetable compartment tray 129, the vegetables and fruits stored in the inner central region of the vegetable compartment tray 129 is cooled There is a problem that it takes a relatively long time before.

In addition, the door basket disposed along the up-down direction on the inner plate surface of the refrigerating chamber door 122 is relatively far from the discharge port through which the cold air is discharged, and is disposed horizontally in the flow direction of the cold air flowing along the up-down direction. The door basket 124 disposed on the lower side is not only difficult to access the cold air, but also exposed to external air when the refrigerator compartment door 122 is opened, so that heat loss is generated so that it is difficult to maintain a sufficient cooling state. There is a problem.

Accordingly, an object of the present invention is to provide a refrigerator in which cold air can be supplied smoothly to a door basket disposed under the vegetable compartment and the refrigerating compartment door.
