Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment enters under premised on technical solutions of the utility model
Row is implemented, and gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following
Embodiment.
See Fig. 1, Fig. 2, present embodiment discloses a kind of refrigerator, including casing, casing includes cold room 1 and refrigerating chamber 2,
Air path system it is provided with in casing.
This air path system includes evaporator chamber 12, is provided with vaporizer 3 and fan component 4 in evaporator chamber 12 from lower to upper, steams
Send out and above device chamber 12, be connected to cold preservation wind inlet channel 7 and freezing wind inlet channel 9, be connected to below evaporator chamber 12
Cold preservation return airway 8 and freezing return airway 10, cold preservation wind inlet channel 7 and freezing wind inlet channel 9 are near evaporator chamber 12
One end be entrance point, the entrance point of cold preservation wind inlet channel 7 and freezing wind inlet channel 9 intersects and arranges in entrance point crossing
Having inlet air door 5, inlet air door 5 rotatably switches thus realizes closing or freezing wind inlet channel 9 of cold preservation wind inlet channel 7
Closing, freezing return airway 10 is the port of export in the one end near evaporator chamber 12, sets at the port of export of freezing return airway 10
It is equipped with return air air door 6.The port of export of cold preservation wind inlet channel 7 all connects with cold room 1 with the entrance point of cold preservation return airway 8,
Evaporator chamber 12 is positioned at refrigerating chamber 2 back, the port of export of freezing wind inlet channel 9 and the entrance point of freezing return airway 10 all with
Refrigerating chamber 2 connects.
In specifically arranging, inlet air door 5 and return air air door 6 are MOD.
Fan component 4 is volute type structure, the fan electromotor including spiral case and being arranged in spiral case and electric fan, utilizes spiral case
Structure reduces airflow pressure loss, facilitates simultaneously and controls air quantity towards cold room 1 or refrigerating chamber 2 by inlet air door 5, it is simple to wind
Road designs.
Freezing wind inlet channel 9 is positioned at the top of refrigerating chamber 2, it is easy to freeze refrigerating chamber 2 front end, improves refrigerating chamber 2 full
