The disadvantage of this air duct device is that the air is serially discharged from both sides and the top of the storage room, the air duct is long, the wind resistance is large, and the cold air It even cannot effectively reach the air outlet at the lower left side, resulting in uneven temperature inside the refrigerator compartment, large temperature difference, slow cooling speed and other defects, which in turn increases the working time of the compressor and increases power consumption.

Invention content:

The technical problem to be solved by the present invention is to overcome defects such as uneven temperature inside the refrigerating chamber of the prior art and large temperature difference, and provide an air duct device in which cold air enters from the bottom on the right side of the storage chamber and blows out in the middle, and contains the air duct device. Refrigerator with channel unit.

The present invention solves technical problem and adopts following technical scheme:

The air channel device of the refrigerator, the air channel device includes an air inlet and a main air channel communicated with the air inlet, at least two secondary air channels are connected in parallel on the main air channel, and each of the secondary air channels is provided with air outlet.

Structural features of the present invention also are:

The air duct device as a whole forms a hollow kitchen knife shape, the air inlet is arranged at the handle of the knife, the main air duct is arranged along the axial direction of the handle of the knife, and the secondary air duct and the main air duct form a " F" shape, the air outlet is located at the position of the knife face.

A partition is provided between two adjacent secondary air ducts, and the partition doubles as a reinforcing rib of the air duct device.

The present invention also includes a refrigerator, in which the aforementioned air duct device is provided, and a groove adapted to the air duct device is provided on the storage chamber of the refrigerator, and the air duct device is embedded in the in the groove.

The storage room of the refrigerator is provided with multi-layer shelves, and the air outlet is located between any two layers of shelves.

The air duct device is arranged on the back panel of the storage room, the main air duct of the air duct device is arranged longitudinally, and the secondary air duct extends leftward along the vertical direction of the main air duct.

The mouth of the groove is provided with an air duct cover plate clamped on the refrigerator liner, and an air hole corresponding to the position of the air outlet of the air duct device is also provided on the air duct cover plate.

The storage room is a refrigerator room, a freezer room or a temperature-changing room.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

The invention has a simple structure and is easy to assemble. The cold air enters from the side of the storage room and blows out from the middle, so that the temperature inside the storage room is uniform. The cold air of the air duct device of the refrigerator of the present invention enters from the air inlet, and is directly distributed to the air outlets of each secondary air duct by multiple branches, which effectively overcomes the long air duct, large wind resistance and cooling effect of the "U" type air duct device series air duct structure. The disadvantage of slow speed reduces the working time of the compressor and reduces the power consumption.

The invention is embedded in the inner container of the storage room of the refrigerator, does not occupy the space of the storage room, and increases the volume of the storage room.
