The first horizontal branch air duct is located at the top in the second horizontal branch air duct.
The beneficial effects of the present invention are: the intracavitary each horizontal branch's Duct design of refrigerator freezing of the invention has inclined-plane, make droplet
Main exhaust passage is flowed back under gravity.Moreover, making the sill of protrusion in the bottom in the second horizontal branch air duct, prevent droplet from filling
Enter its leg and freezes air outlet.In this way, making most droplet in the channel of the forward position of ice-formation condition formation refrigeration air delivery duct
It is sent into cold storage cavity.Droplet does not stop slowly to evaporate in cyclic process cold wind, returns evaporator along presetting return air path, and
It is attached on fin in the form of frost.
Refrigerating chamber exhaust passage switch the muscle that encloses assembled up with shelves muscle, as one added hamper, dripping cannot pierce open
The fit clearance with plate washer is closed, to effectively solve the problems, such as that droplet freezes knob.
