Abstract:

An air-cooled refrigerator (100). The air-cooled refrigerator (100) comprises an air duct assembly (300, 400) and an air door shielding device (500). The air duct assembly (300, 400) is provided with an accommodating cavity (105) with a backward air inlet. A plurality of air supply communicating holes (106) is formed on the peripheral wall of the accommodating cavity (105). The air door shielding device (500) is provided with a shielding part (520). The shielding part (520) is provided with a plurality of air baffles (521). The shielding part (520) is rotatably provided in the accommodating cavity (105) and has shielding positions where all the air supply communicating holes are completely shielded by the air baffles (521), and then the air in a cooling chamber is prevented from entering at least one storage chamber (101) by means of the plurality of air supply communicating holes in the defrosting process of the air-cooled refrigerator (100). The bottom of the sidewall of the accommodating cavity (105) is provided with a water guide groove (381) inclined backwards and downwards. The air duct assembly (300, 400) is provided with a water outlet hole (382) communicating the rear side of the air duct assembly (300, 400) with the rear end of the water guide groove (381), so that water in the accommodating cavity (105) flows out of the air duct assembly (300, 400) by means of the water guide groove (381) and the water outlet hole (382). The air door shielding device (500) adopts a rotary structure and is small in size, simple, compact and convenient to control. Condensate water at the air door shielding device (500) can be smoothly discharged by means of a special defrosted water discharge channel.
