When the second cooling compartment 1121 needs cooling, the damper 5 is opened, and the cold air passes through the first air duct 31 and the second air duct 41 in sequence and enters the second cooling compartment 1121. When the second cooling compartment 1121 does not require cooling, the damper 5 is closed, and the cold air in the first air duct 31 cannot enter the second air duct 41.

Referring to fig. 5 and 12, and referring to fig. 4, the fan 6 is disposed in the first air duct 31 and faces the first air inlet 321 of the first air duct 31, and the wind direction of the fan 6 faces the first air duct 31, so that the fan 6 brings the cold air in the refrigeration space where the evaporator is located into the first air duct 31, the flow of the cold air is accelerated, and the refrigeration efficiency of the refrigerator is improved.

In some embodiments, the fan 6 is a radial flow fan 6, and the rotation axis of the radial flow fan 6 is perpendicular to the rear wall of the first tank container 111, so that the radial flow fan 6 brings the cold air in the refrigeration space where the evaporator is located into the first air duct 31, and the cold air is blown out along the radial direction of the radial flow fan 6, so that the cold air is fully diffused into the first air duct 31, and it is ensured that the air outlet from the plurality of first air outlets 331 on the first air duct 31 is uniform, so that the temperature in the first refrigeration compartment 1111 is more uniform. In addition, the radial flow fan 6 is thin, so that the first air duct 31 does not need to be thick, and the volume of the first refrigerating chamber 1111 can be reduced.

FIG. 13 is a schematic view of the duct cover and fan of FIG. 5.

Referring to fig. 13, in some embodiments, three mounting posts 332 are protruded from the back side of the air duct cover plate 33, and the three mounting posts 332 are arranged in a triangle. The runoff fan 6 is arranged between the three mounting columns 332, three clamping portions 61 are convexly arranged on the periphery of the runoff fan 6, and the clamping portions 61 are clamped with the mounting columns 332 in a one-to-one correspondence manner, so that the runoff fan 6 is stably fixed on the air duct cover plate 33.

Referring to fig. 8 to 10 and fig. 3, in some embodiments, an air inlet portion 423 is convexly disposed on a front side surface of the first portion 42, the air inlet portion 423 is sandwiched between the first container liner 111 and the second container liner 112, and the air inlet is disposed on a side of the air inlet portion 423 facing the first container liner 111, so that the air inlet 422 is located at a radial air outlet end of the radial flow fan 6, and thus the radial flow fan 6 not only can fully diffuse cold air in a refrigeration space where the evaporator is located into the first air duct 31, but also can drive the cold air in the first air duct 31 to enter the second air duct 41.

Referring to fig. 10 in combination with fig. 3, in some embodiments, the air inlet portion 423 of the first portion 42 extends vertically and is perpendicular to the first connecting plate 424, the first portion 42 abuts against the right side surface of the first container 111 through the air inlet portion 423, and the first connecting plate 424 abuts against the top of the first container 111, so that the first portion 42 can be attached to the back surface of the first container 111 more stably. Meanwhile, the second portion 43 and the first portion 42 may be integrally formed, so that the second portion 43 can be more stably attached to the back surface of the second tank liner 112.

Referring to fig. 5 and 12, the air guide member 7 is disposed in the first air duct 31, an air guide cavity 71 is disposed in the air guide member 7, an air inlet end of the air guide cavity 71 is communicated with the first air duct 31, and an air outlet end of the air guide cavity 71 is communicated with the second air duct 41, so that the air guide cavity 71 is utilized to guide the cold air in the first air duct 31 into the second air duct 41, thereby ensuring the air inlet amount of the second air duct 41.

In some embodiments, the air inlet end of the air guiding cavity 71 is larger than the air outlet end of the air guiding cavity 71, so that more cold air in the first air duct 31 enters the second air duct 41 through the air guiding cavity 71.

In some embodiments, the damper 5 is detachably disposed in the air guiding cavity 71, and when the damper 5 is opened, the cool air in the air guiding cavity 71 circulates, so that the cool air in the first air duct 31 can enter the second air duct 41 through the air guiding cavity 71. When the damper 5 is closed, the air guiding cavity 71 is closed, so that the cold air in the first air duct 31 cannot enter the second air duct 41 through the air guiding cavity 71.

Based on the technical scheme, the embodiment of the utility model at least has the following advantages and positive effects.

According to the refrigerator provided by the embodiment of the utility model, the second air channel 41 is formed in the air channel piece 4, the air inlet end of the second air channel 41 is communicated with the first air channel 31, and therefore cold air in the first air channel 31 can be introduced into the second air channel 41. The air outlet end of the second air duct 41 is communicated with the air vent 1122 on the second tank container 112, so that the cold air in the second air duct 41 can be introduced into the second refrigeration chamber 1121 in the second tank container 112, and the refrigeration of the second refrigeration chamber 1121 is realized.

For example, when the first cooling compartment 1111 is a freezing compartment, the second cooling compartment 1121 is a refrigerating compartment, and the first air duct 31 is a freezing air duct, the freezing air duct is communicated with the space where the evaporator is located, so that the cold air generated by the evaporator can enter the second air duct 41 through the freezing air duct, and the cold air is introduced into the refrigerating compartment in the second cabinet container 112 through the second air duct 41, thereby refrigerating the refrigerating compartment.

Therefore, the second refrigeration compartment 1121 can be refrigerated by only installing one air duct member 4, and the assembly is simple and the production efficiency is high. Furthermore, the vent 1122 is directly punched on the second tank container 112, and a cover plate assembly does not need to be arranged in the second refrigeration compartment 1121 to form the vent 1122, so that the refrigerator is more attractive. In addition, since the air duct member 4 is disposed in the foamed layer between the cabinet 1 and the first cabinet container 111 and between the cabinet 1 and the second cabinet container 112, the air duct member 4 does not occupy the internal space of the second cooling compartment 1121, so that the second cooling compartment 1121 has a larger storage capacity.
