摘要： A muffling device and refrigerating and freezing apparatus. The muffling device, comprising a muffling body, the muffling body having a sound ingress and egress surface, at least one muffling chamber is provided inside the muffling body , the sound ingress and egress surface is provided with at least one communication port, each of the communication port connecting one or more of the muffling chamber, each of the muffling chamber is connected to the outside of the sound ingress and egress surface through at least one of the communication port. In the muffling device and refrigerating and freezing apparatus, when noise passes through the through-holes of the muffling device, the sound is transmitted through the communication ports into the muffling chamber, extending the sound propagation path, weakening the sound energy, and thereby reducing the sound that continues to disperse outward. Specifically, the length of at least one muffling chamber is between 0.0085m to 0.85m. The length of the muffling chamber is set so that the incident sound waves and reflected sound waves at the communication ports of the muffling chamber overlap, with the amplitudes being as equal as possible and the phases being inverted by 180° as much as possible, thus maximizing the cancellation of sound waves to achieve the purpose of muffling or noise reduction.

摘要： A refrigerator includes a storage liner, an evaporator, an air supply duct, and an 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.

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.
