Embodiment Construction

[0021] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The present invention provides an air-cooled refrigerator. In the first embodiment of the air-cooled refrigerator of the present invention, refer to figure 1 and figure 2 ,in figure 2 The direction A in the figure represents the top, and the direction B represents the bottom. The air-cooled refrigerator includes a refrigerating compartment 1, a freezing compartment 2, a freezing air outlet fan 3, and an air duct structure 4 connecting the refrigerating compartment 1 and the freezing compartment 2. The structure 4 includes an air inlet duct 41 and a return air duct 42 that communicate with each other. The air inlet duct 41 includes a first air inlet 411 that communicates with the refrigerated compartment 1 and a second air inlet 412 that communicates with the freezer compartment 2. The return air The air duc...

Abstract

The invention discloses an air-cooled refrigerator which comprises a refrigeration chamber, a freezing chamber, a freezing air outlet fan and an air channel structure communicated with the refrigeration chamber and the freezing chamber. The air channel structure comprises an air inlet channel and an air return channel communicated with the air inlet channel. The air inlet channel comprises a first air inlet communicated with the refrigeration chamber and a second air inlet communicated with the freezing chamber. The air return channel comprises a first air return opening communicated with the refrigeration chamber and a second air return opening communicated with the freezing chamber. The freezing air outlet fan is arranged in the air inlet channel and blows airflow to the air inlet channel. An air return fan is arranged in the air return channel and blows airflow of the refrigeration chamber to the air return channel. The flow speed of cold airflow entering the freezing chamber from the air return channel is improved, the time consumed by the cold airflow entering the freezing chamber from the air return channel is shortened, and the air return openings of the freezing chamber of the air-cooled refrigerator are prevented from being iced.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an air-cooled refrigerator. Background technique [0002] At present, an air-cooled refrigerator includes a refrigerated compartment and a refrigerated compartment. The cold air is sent to the refrigerated compartment through the air inlet duct through the refrigerated air outlet fan installed in the refrigerated compartment, and then the cold air returns to the refrigerated compartment through the refrigerated compartment and the return air duct. However, since the temperature of the refrigerated room is generally maintained at 3°C ​​to 7°C and the temperature of the refrigerated room is kept at minus 18°C, the temperature of the cold air returning from the refrigerated room is above zero. The outlet of the return air channel of the freezer room forms an alternation of cold and heat, so that the gaseous water or / and liquid water brought back from the refrigerated compartme...
