In order to accelerate the air flow circulation, a first air blower 103 is further arranged on the upstream of the first evaporator 101 in the air flow path, and the first air blower 103 is configured to cause the return air flow in the storage compartment 131 to flow into the cooling compartment 102 to be cooled by the first evaporator 101 and cause at least part of the cooling air flow to flow into the storage compartment 131.

In this embodiment, the lowermost space in the storage liner 130 defines the cooling chamber 102 accommodating the first evaporator 101, and the first evaporator 101 no longer occupies the rear space of the lowermost storage compartment 131, thereby increasing the depth of the storage compartment 131, improving the space utilization of the refrigerator 100, and facilitating the storage of articles which are large in size and are not easy to separate.

In addition, in the conventional refrigerator 100, the storage compartment 131 located at the lowest position is low, and a user needs to bend down or squat down greatly to perform the operation of taking and placing articles in the storage compartment 131, which is inconvenient for the user to use, especially for the elderly. In the embodiment, the cooling chamber 102 occupies the lower space of the storage liner 130, so that the height of the storage chamber 131 above the cooling chamber 102 is raised, and the stooping degree of the user when the user takes and places the storage chamber 131 is reduced, thereby improving the use experience of the user.

The first evaporator 101 may be disposed in the cooling chamber 102 in a flat cubic shape, i.e., the long and wide sides of the first evaporator 101 are parallel to the horizontal plane, the thickness side is perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the first evaporator 101. By placing the first evaporator 101 horizontally in the cooling chamber 102, the first evaporator 101 is prevented from occupying more space, and the storage volume of the storage compartment 131 in the upper portion of the cooling chamber 102 is further ensured.

The refrigerator 100 further includes a first air supply duct 133, and the first air supply duct 133 is formed with at least one first air supply outlet 133a communicating with the storage compartment 131 and a first air supply inlet communicating with a rear end of the cooling compartment 102 to deliver at least a part of the air flow cooled by the first evaporator 101 into the storage compartment 131.

As shown in fig. 2, the first blower 103 is a centrifugal fan, and a rotation shaft of the first blower 103 is parallel to the lateral direction. Specifically, the first blower 103 is a double-suction centrifugal fan, and the return air flows in the two storage spaces enter the accommodating cavities of the vertical partition 134 through the corresponding first return air inlets 134a under the driving of the first blower 103, and further flow downward into the cooling chamber 102 to be cooled by the first evaporator 101.

In the preferred embodiment, the accommodating chamber is adjacent to the cooling chamber 102 and to the front end of the vertical partition 134, and accordingly, the first blower 103 is adjacent to the cooling chamber 102 and to the front end of the vertical partition 134, and the first return air inlet 134a is adjacent to the cooling chamber 102 and to the front end of the vertical partition 134, that is, the first blower 103, the first return air inlets 134a on both sides are adjacent to the cooling chamber 102 and to the first door 132. The cold air blows into the storage space from the rear part, and all the cold air flows back into the cooling chamber 102 through the first air return inlet 134a on the front side after passing through the articles stored in the storage space, so that the utilization rate of the cold air is improved, and the loss of the cold energy is reduced.
