Description
Technical field
The present invention relates to refrigerator art, more specifically, it is related to a kind of air channel structure and a kind of refrigerator.
Background technology
At present, the regions of needs is sent to by the vertical air channel of refrigerator due to carrying the air-flow of cold, makes refrigerator can be with
Carry out normal refrigeration work.As depicted in figs. 1 and 2, it is provided with the vertical air channel 10 in the refrigerator 1 in correlation technique smooth
Flow-guiding structure 11, but gradually reduced in one end static pressure that air-flow is sent out in vertical air channel 10, and the speed for the air-flow sent out
It is gradually reduced, now air-flow is difficult to reach top area, while even reach top area, the air velocity at top is also very
It is small, therefore in order to solve the above problems, it is proposed that two kinds of solutions, one is to provide the blower fan of bigger rotating speed, and two be exploitation one
The bigger blower fan of pressure head is planted, still, the big blower fan of rotating speed can produce larger noise, and the bigger blower fan of exploitation pressure head needs
Longer construction cycle and more development cost.
Therefore, how to increase air-flow send out vertical air channel when speed, allow mass air flow reach the door seal of refrigerator with
And the top of refrigerator, as urgent problem to be solved.
The content of the invention
It is contemplated that at least solving one of technical problem present in prior art.
Therefore, it is an object of the present invention to provide a kind of air channel structure and a kind of refrigerator, by the vertical air channel of refrigerator
