摘要： The present disclosure provides a noise reduction device. The noise reduction device includes an outer connecting tube, and the outer connecting tube includes a first end connected to a capillary tube and a second end connected to an evaporator, wherein a plurality of porous wire meshes arranged at an interval is disposed in the outer connecting tube, and side edges of the porous wire meshes abut against an inner wall surface of the outer connecting tube; and pore diameters of the plurality of porous wire meshes are gradually reduced from the first end to the second end. By providing the plurality of porous wire meshes having gradually changing pore diameters in the outer connecting tube to form the noise reduction device connected to the capillary tube and the evaporator, large bubbles formed at an ejection port of the capillary tube can be gradually dispersed and reconstituted to form small bubbles when passing through the noise reduction device, such that noise generated when the bubbles are broken can be reduced, thereby playing a role in noise reduction.

摘要： A refrigerator includes a lowermost storage liner, an evaporator, an air supply duct, and at least one air supply fan. A storage compartment and a cooling chamber positioned under the storage compartment are defined in the storage liner. The evaporator is disposed in the cooling chamber and is configured to cool air passing through the evaporator so as to form cooling air supplied to the storage compartment. The air supply duct is disposed in a space defined by the storage liner and is configured to convey the cooling air cooled by the evaporator to the storage compartment. The air supply fan is disposed in the air supply duct and is configured to promote air circulation between the cooling chamber and the storage compartment. According to the refrigerator of the present invention, by disposing the air supply fan in the air supply duct, the cooling chamber is prevented from being occupied by the air supply fan, the height of the cooling chamber can be reduced, the storage volume of the storage compartment above the cooling chamber can be increased, the distance between the air supply fan and the evaporator can be relatively increased, and the degree of frosting of blades of the air supply fan can be reduced.

摘要： A refrigerator includes a cabinet, in which a cooling chamber and at least one storage space are defined, the cooling chamber being arranged at the bottom of the cabinet and directly below the storage space; a door body, which is arranged on a front surface of the cabinet so as to operably open and close the storage space; an evaporator, which is wholly horizontally placed in the cooling chamber in the shape of a flat cube, and is configured to provide cooling capacity to the storage space; and a liquid storage bag, which is arranged in the cooling chamber and connected to the evaporator. An included angle between a center line of the liquid storage bag and a horizontal line is 1° to 89°. In the refrigerator of the present invention, the liquid storage bag is arranged in the cooling chamber, and a foam layer and a housing of the refrigerator may block the sound transmission of the flow of a liquid refrigerant, and in particular, the foam layer has a good sound insulation effect. The liquid storage bag is connected to the evaporator and the included angle between the center line of the liquid storage bag and the horizontal line is 1° to 89°, which can make the internal structure of the cooling chamber compact and prevent the occupation of too much space.
