Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described implementation Example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field Those of ordinary skill's every other embodiment obtained without creative efforts, belongs to the utility model The range of protection.

Please refer to Fig. 1 to Fig. 6, the refrigerator air duct component of the present embodiment is installed on refrigerator body liner 13, rear lower with Cavity is formed between box liner 13, as evaporator chamber 15, evaporator 14 is installed in evaporator chamber 15, refrigerator air duct The structure setting of component are as follows:

1 rear end opening of freezing mask of internal cavities, built-in freezing air duct 24, freezing air duct 1 are assemblied in freezer surface The open end of cover 1, upper rear end are protruded to form " Jiong " shape inner cavity backward, and as return airway 11, return airway 11 is with top Interconnection as air inlet area, using the bottom end opening of two sides vertical passageway as the first air outlet 12, with 15 phase of evaporator chamber Connection；

It freezes mask 1 and is equipped with multiple air outlets 2 for blowing to refrigeration compartment, freeze and set in the shell in air duct 24 Wind inlet channel 6 is correspondingly arranged multiple second air outlets 5 according to the position of each air outlet 2 on shell, and is connected with wind inlet channel 6 It is logical, freeze in the mounting hole of 24 upper rear end of air duct and blower 7 be installed, and set above blower 7 first air inlet and second into Air port, sets the first air door 8 in the first air inlet, the air inlet area of face return airway 11, both be connected, set in the second air inlet Second air door 9, is connected with wind inlet channel 6；The position that mounting hole is corresponded on freezing air duct 1 sets aperture, with evaporator chamber 15 communicate；
