[0043] The assembly steps of the air duct assembly include:

[0044] Step 1: Install the lower fan on the rear cover. Specifically, glue PE around the lower fan and insert it into the main air inlet on the rear cover.

[0045] Step 2: Install and embed the first damper and the second damper into the foam assembly. Specifically, the first damper is sandwiched between the first foam block and the second foam block, and the first foam block and the second foam block are connected together. At the same time, the second damper is sandwiched between the second foam block and the third foam block, and the second foam block and the third foam block are connected together.

[0046] Step 3: Install the foam assembly on the front cover, and then install the front cover on the rear cover. Specifically, after the foam assembly is installed on the front cover, the front cover is clamped on the rear cover; further, for the assembly of the auxiliary air duct, the rear cover needs to be installed in the box, and then the auxiliary air duct is installed on the top of the rear cover to complete the assembly of the air duct assembly.

[0047] In addition, after the lower air duct assembly 2 is successfully assembled, the lower evaporator 1 and the lower air duct assembly 2 need to be installed in the lower inner tank 1-1. The specific steps are as follows:

[0048] Step 101, the lower evaporator is installed on the rear wall of the lower inner tank;

[0049] Step 102, the rear cover plate is connected to the front cover plate and the foam assembly and installed on the rear wall of the lower inner tank, the rear cover plate covers the lower evaporator, and an evaporation chamber is formed between the rear cover plate and the lower inner tank;

[0052] By setting a foam component between the front and rear cover plates, an air outlet cavity will be formed between the foam component and the rear cover plate. The cold air formed by heat exchange in the evaporator enters the air outlet cavity for centralized transportation. At the same time, channels for air supply and return are provided in the foam component to meet the cold air outlet requirements of multiple air outlets of the front cover plate, so as to meet the multiple air outlet requirements in a smaller volume, so as to realize the miniaturized air duct component design to meet the air supply requirements of multiple temperature zones of the refrigeration equipment, so as to improve the user experience.

[0053] Based on the above technical solution, optionally, for the upper inner liner 2-1, an upper air duct assembly 6 is provided in the upper inner liner 2-1, and the upper air duct assembly 6 includes an upper air duct and an upper fan 60 arranged in the upper air duct, and the upper fan 60 drives the air in the upper inner liner 2-1 to circulate to achieve air cooling. Specifically, in order to maximize the use of the longitudinal dimension space of the upper inner liner 2-1 to hold wine, the upper evaporator 1' for cooling the upper inner liner 2-1 is located on the outside of the upper inner liner 2-1 and attached to the back of the upper inner liner 2-1, and the upper air duct includes an air duct cover 61, which is located on the inside of the upper inner liner 2-1 and arranged on the back of the upper inner liner 2-1. An upper air duct is formed between the air duct cover 61 and the upper inner liner 2-1. The upper air duct is also provided with an upper return air port 611 for returning air, and an upper air outlet 612 for discharging air. The upper fan 60 is located in the upper air duct. Specifically, by installing the upper evaporator 1' on the outside of the upper inner liner 2-1, since the upper evaporator 1' is attached to the back of the upper inner liner 2-1, the cold energy generated by the upper evaporator 1' directly cools the upper inner liner 2-1, so that the upper inner liner The temperature at the back of the tank 2-1 is reduced, and the back of the inner wall of the upper inner tank 2-1 cooperates with the duct cover 61 to form an upper duct. Under the action of the upper fan 60, the air entering the upper duct from the upper return air port 611 exchanges heat with the back of the inner wall of the upper inner tank 2-1, and is output from the upper air outlet 612 to the outside of the upper duct after being cooled to cool the items stored in the upper inner tank 2-1. Since the upper evaporator 1' is located outside the upper inner tank 2-1 and does not occupy the storage space in the upper inner tank 2-1, the longitudinal size of the storage space in the upper inner tank 2-1 can be effectively increased. At the same time, since the upper evaporator 1' is externally arranged in the upper duct, there is no need to consider the safety distance between the duct cover 61 and the upper evaporator 1'. The duct cover 61 can be installed as close to the back of the upper inner tank 2-1 as possible while satisfying the air circulation, thereby further increasing the storage capacity of the upper inner tank 2-1. The upper fan 60 can be a centrifugal fan, which is installed on the air duct cover 61 and covers the upper return air outlet 611. A fan cover 62 is also provided outside the upper fan 60, and an exhaust port (not marked) is provided on the fan cover 62. In actual use, the upper return air outlet 611 is arranged at the bottom of the air duct cover 61, and upper air outlets 612 are provided on both sides and / or the top of the air duct cover 61. The upper air outlet 612 is located above the upper return air outlet 611. In this way, the cold air of the upper liner 2-1 can be evenly distributed by utilizing the principle of cold air sinking. An antibacterial module 63 is also provided in the upper air duct, and the antibacterial module 63 is located on one side of the upper fan 60, and exhaust ports are provided on both sides of the fan cover 62, one of which blows air toward the antibacterial module 63.Further, in order to save installation space to the maximum extent, a lighting lamp 7 is provided on the top of the air duct cover 61. Specifically, the lighting lamp 7 includes a lamp holder 71, an LED light bar 72 and a lampshade 73. The LED light bar 72 is installed on the lamp holder 71, and the lampshade 73 covers the LED light bar and is installed on the lamp holder 71. The lighting lamp 7 is installed on the top of the air duct cover 61 through the lamp holder 71, so that the lighting can be provided from the top while reducing the impact of the lighting lamp 7 on the storage space. Preferably, in order to facilitate installation, the lamp holder 71 is installed on the air duct cover 61 in a card-mounted manner. Specifically, a mounting card slot 613 is formed on the top of the air duct cover 61, and the lamp holder 71 is card-mounted in the mounting card slot 613 to achieve installation. In addition, in order to increase the contact area between the upper evaporator 1' and the upper liner 2-1, the upper evaporator 1' can adopt a plate evaporator.
