The air-cooled refrigerator utilizes air circulation to cool, when high-temperature air flows through the evaporator in the air duct, the temperature of the air is high, and the evaporator is low in temperature, so that the temperature of the air is reduced by heat exchange between the high-temperature air and the evaporator, and then the air is blown into a storage chamber of the refrigerator through a fan, and the temperature in the storage chamber of the refrigerator is reduced through continuous air circulation. Because the water vapor exists in the air, when the temperature of the water vapor is reduced, the water vapor can be condensed to cause frosting on the evaporator, therefore, when the frosting on the evaporator is generated, the frost on the evaporator can be melted by heating the heating wire, the melted frosting water flows to the bottom end of the air duct and flows into the container at the bottom of the shell through the drain pipe below the liner, and the frosting of the evaporator is completed.
After the door body is closed, a closed space is formed in the inner container, and a certain negative pressure is formed in the inner container at the moment when the door body is closed or opened, so that the drain pipe is the only part capable of balancing the air pressure inside and outside the inner container, and external air can be sucked through the drain pipe, so that the air pressure inside and outside the inner container is balanced, however, frost water is generally accumulated in a container at the bottom of the refrigerator shell, water and air in the container are easily sucked into the drain pipe together, the air rises in the drain pipe, and the water can fall under the action of gravity, so that the water suction noise of gurgling is generated while the negative pressure in the inner container is balanced, and the user experience is reduced.
To above-mentioned problem, prior art is through seting up the through-hole on the lateral wall of drain pipe, and when the inside negative pressure that produces of inner bag, the drain pipe can inhale outside air through this through-hole to balanced inside negative pressure, in order to avoid water in the container to be adsorbed the drain pipe, thereby eliminate the noise of absorbing water. However, after the through hole is formed in the side wall of the drain pipe, when the refrigerator works normally, external hot air can enter the drain pipe through the through hole and then enter the inner container, so that the storage temperature in the inner container is increased, the power consumption of the refrigerator is increased, and the fresh-keeping effect of the refrigerator is affected.
