Problems solved by technology
[0008] However, according to the cooling air distributing device of the conventional refrigerator having the above-mentioned structure, the temperature around the distribution hole 11 where the cooling air is supplied is lower than a predetermined temperature, and the surrounding temperature of the side panels 5 or the refrigerator door not supplied with the cooling air is higher.
As a result, the temperature distribution throughout the cooling chamber is uneven, reducing the freshness of the food
In addition, the shelves obstruct the flow of the cold exhausted air, adversely affecting the smooth circulation of air in the cooling chamber

Embodiment Construction
[0023] Referring to FIG. 2 , an embodiment of the refrigerator with the cooling air distribution rack of the present invention is mainly composed of a cooling air distribution rack 120 and a cooling chamber.
[0024] The cooling chamber is surrounded by two side plates 117 and a rear plate 115, and at the center of the rear plate 115, cooling air supply ducts 110 vertically upward and downward are provided. Rack support tables 103 supporting the dispensing rack 140 protrude from opposite portions of the side plates 117 .
[0025] The supply duct 110 protrudes both vertically upward and downward from the center of the rear plate 115 and partially protrudes toward the interior of the cooling chamber, the supply duct having a hollow structure that smoothly circulates cooling air. In the supply duct 110 , a distribution hole 113 for spraying cooling air is provided at the position of the rack support table 103 for supporting the cooling air distribution rack 140 . Opening / closing...

A refrigerator having a cool air dispersing shelf is inherently installed with a dispersing apparatus for spreading the cool air to the shelf for consistently dispersing the cool air throughout the interior of a cooling chamber within a short time period, and supplies the cool air to respective shelves simply by installing / removing the shelves. For this, a supply duct circulated with the cool air supplied into the cooling chamber therethrough has at least one discharging hole toward the cooling chamber, and an open / close member is installed in the supply duct for opening / closing the discharging hole in accordance with the installation / separation of the shelf. Also, the shelf is formed with cool air spray holes in the lower plane and a pushing portion provided by one end of a cool air suction hole for opening / closing the open / close member.
Description
technical field [0001] The present invention relates to a refrigerator with a device for efficiently distributing cooling air, and more particularly, to a refrigerator with a cooling air distribution shelf in which the cooling air is distributedly supplied to the shelves installed in the refrigerator so that Even temperature distribution throughout the refrigerator. Background technique [0002] In a conventional refrigerator, the low-temperature cooling air generated by the evaporator is sent to the freezing chamber and the cooling chamber by the operation of the fan. However, as the storage capacity increases, when the cooling air is supplied only by the cooling air supply duct, the cooling air circulates unevenly in the cooling chamber. Therefore, the dedicated location receiving the cooling air is at a low temperature. In addition, the shelf installed in the cooling chamber causes uneven distribution of the supplied cooling air in the cooling ch...
