The air duct assembly 100 and the refrigeration apparatus of the present utility model are described below in conjunction with fig. 1 to 5.

As shown in fig. 1 to 3, the air duct assembly 100 according to the first aspect of the present utility model is disposed in a cavity of a liner 200, and the cavity includes a first refrigeration compartment 201 and a second refrigeration compartment 202 located on two sides of the air duct assembly 100, respectively. The air duct assembly 100 divides the cavity into a first refrigerated compartment 201 and a second refrigerated compartment 202. The air duct assembly 100 is internally provided with a containing cavity for containing the evaporator, the air duct assembly 100 comprises a first side wall 103 and a second side wall 104, the first side wall 103 is positioned on one side of the first refrigeration compartment 201 and is provided with a first air return port 101 communicated with the containing cavity, the second side wall 104 is positioned on one side of the second refrigeration compartment 202 and is provided with a second air return port 102 communicated with the containing cavity.

And since the first side wall 103 is located in the first refrigerated compartment 201, the second side wall 104 is located in the second refrigerated compartment 202. A first air return port 101 is formed at a side of the air duct assembly 100 facing the first refrigerating compartment 201, and a second air return port 102 is formed at a side of the air duct assembly 100 facing the second refrigerating compartment 202. The first air return port 101 and the second air return port 102 are located on the same air duct assembly 100, and a containing cavity for containing the evaporator on the air duct assembly 100 is simultaneously communicated with the first air return port 101 and the second air return port 102. The first air return port 101 and the second air return port 102 are arranged in a staggered manner, so that the positions of the first air return port 101 and the second air return port 102 for returning air are different, and the positions of the first air return port 101 and the second air return port 102 for returning air are staggered.

When the air duct assembly 100 is used, the cold air cooled by the evaporator firstly enters the first refrigeration compartment 201 and the second refrigeration compartment 202 for cooling, the cold air in the first refrigeration compartment 201 can return to the accommodating cavity of the air duct assembly 100 through the first air return port 101, and the cold air in the second refrigeration compartment 202 can also return to the accommodating cavity of the air duct assembly 100 through the second air return port 102, so that the refrigeration cycle is completed. In the whole process, due to the dislocation arrangement of the two return air inlets, the return air entering through the first return air inlet 101 cannot directly contact with the return air entering through the second return air inlet 102, and the return air is led to different areas corresponding to the evaporator, so that the different refrigeration demands of the first refrigeration compartment 201 and the second refrigeration compartment 202 are ensured.

According to the air duct assembly provided by the embodiment of the utility model, the air duct assembly 100 is arranged in the cavity of the box liner 200, the air duct assembly 100 is utilized to divide the cavity to form the first refrigeration compartment 201 and the second refrigeration compartment 202, the first air return port 101 communicated with the accommodating cavity is formed at one side of the air duct assembly 100, which is positioned in the first refrigeration compartment 201, the second air return port 102 communicated with the accommodating cavity is formed at one side of the air duct assembly 100, the two air returns are combined and positioned in the same area, the first air return port 101 and the second air return port 102 which are arranged in a staggered manner are formed by utilizing the single air duct assembly 100, and the two air returns are correspondingly arranged in different areas of the evaporator in the accommodating cavity, so that frosting of the evaporator is more uniform, and the frosting effect of the whole air duct assembly is improved.

In an embodiment of the present utility model, as shown in fig. 1 to 5, the refrigerating temperature of the first refrigerating compartment is lower than the refrigerating temperature of the second refrigerating compartment; the first side wall 103 is provided with a first return air channel, the first return air inlet 101 is communicated with the accommodating cavity through the first return air channel 105, the second side wall 104 is provided with a second return air channel 106, and the second return air inlet 102 is communicated with the accommodating cavity through the second return air channel 106; because the first air return port 101 and the second air return port 102 are disposed on the same air duct assembly 100, the air return temperature of the second air return port 102 is higher than the air return temperature of the first air return port 101, and the second air return port 102 is easily exposed in a refrigeration environment. So that the second return air duct 106 extends downward in the return air direction, and the height of the second return air duct 106 near the end of the accommodating chamber is lower than the height of the second return air duct 106 far from the end of the accommodating chamber. The condensation at the second air return port 102 can flow back to the accommodating cavity through the gradient at the second air return channel 106, so that the condensation is prevented from entering the temperature changing chamber or collecting at the second air return port 102.

It can be understood that, according to actual requirements, the first air return port 101 and the second air return port 102 may be disposed at other asymmetric positions on two sides of the air duct assembly 100, and the sizes and the numbers of the first air return port 101 and the second air return port 102 may be correspondingly adjusted according to the difference of the air return volumes, so as to meet different refrigeration requirements.

In another embodiment, as shown in fig. 1 to 5, since the first air return port 101 and the second air return port 102 are easy to be condensed, the first air return port 101 and the second air return port 102 are generally connected to the bottom of the accommodating cavity, so that the condensed liquid at the first air return port 101 and the second air return port 102 is directly introduced to the bottom of the accommodating cavity for facilitating subsequent discharge.

In this embodiment, the first air return port 101 communicates with the bottom of the accommodating cavity through the first air return channel 105, and the second air return port 102 communicates with the bottom of the accommodating cavity through the second air return channel 106.

Further, the first air return port 101 and the second air return port 102 have different central positions, so that the central positions of the air return are different, and the air return has different flowing tendencies after entering, so that direct contact of two air return can be further avoided, and the air return is guided to different areas of the evaporator.

Further, in order to avoid that two return air enters the same area of the evaporator, the second return air channels 106 corresponding to the second return air openings 102 are inclined backward, so as to guide the wind direction backward. The first return air channel 105 corresponding to the first return air inlet 101 may be disposed obliquely forward (or forward) to guide the air forward (or forward) so that the two return air positions are in different orientations to correspond to different areas of the evaporator.

In one specific embodiment, as shown in fig. 5, the second return air channel 106 has a diamond-shaped cross-section in the horizontal direction, guiding the return air direction and angle to avoid contact with the return air in the first return air channel 105. As shown in fig. 4, the cross section of the second air return channel 106 in the vertical direction is inclined, the second air return channel 106 extends downwards along the air return direction, the height of the second air return channel 106 near one end of the accommodating cavity is lower than that of the second air return channel 106 far away from one end of the accommodating cavity, on one hand, the air return direction can be adjusted, two air return contacts are further avoided, and in addition, condensation can be prevented from entering the second refrigeration compartment 202 through the arrangement mode.

In an example, as shown in fig. 1 to 5, a return air grille is disposed in the first air return port 101 or the second air return port 102, or a return air grille may be disposed in both the first air return port 101 and the second air return port 102, where the return air grille is used to intercept coarse floating objects and suspended objects in the return air, and prevent the floating objects and suspended objects from entering the accommodating cavity.
