Refrigerator air duct structure, refrigerator refrigerating air duct, refrigerator freezing air duct, and refrigerator
View Patent ↗The present disclosure relates to the technical field of refrigerators and manufacturing therefor, and in particular, to a refrigerator air duct structure, a refrigerator refrigerating air duct, a refrigerator freezing air duct, and a refrigerator. The refrigerator air duct structure comprises a groove integrally formed on a refrigerating container liner and a cover plate covering the groove; the groove is communicated with an air supply duct, and comprises a main groove and a plurality of branch grooves communicated with the main groove; the plurality of branch grooves are arranged at intervals on the refrigerator container liner; and the cover plate is provided with a through-hole for allowing cold air to flow into a refrigerator body of a refrigerator. According to the present disclosure, the refrigerator air duct structure is naturally formed by means of the cover plate and the plastic groove of the container liner, thereby reducing assembly sub-parts for a refrigerating air duct and a freezing air duct, making operation steps simple during assembly of the air ducts, canceling in-refrigerator splicing operations for conventional air ducts and air supply ports, reducing cold leakage caused by poor sealing, and reducing the risk of freezing at the bottom of a refrigerating chamber and freezing in a freezing chamber.
1 . A refrigerator air duct structure, comprising a groove integrally formed on a refrigerator inner liner and a cover plate covering the groove, the refrigerator inner liner forms a main structural wall of a refrigerator storage chamber, wherein
the groove is communicated with an air supply duct and comprises a main groove and a plurality of branch grooves communicated with the main groove, and the plurality of branch grooves are arranged at intervals on the refrigerator inner liner;
and the cover plate is provided with a through-hole for cold air to flow into the refrigerator storage chamber.
2 . The refrigerator air duct structure of claim 1 , wherein there are two branch grooves, comprising a first branch groove and a second branch groove that are arranged at an interval in parallel.
3 . The refrigerator air duct structure of claim 2 , wherein an air guide direction of the first branch groove is the same as that of the main groove, and an inclined groove is arranged between the second branch groove and the main groove for cold air to circulate.
4 . The refrigerator air duct structure of claim 3 , wherein an included angle between the length direction of the inclined groove and the length direction of the main groove is 20°-80°.
5 . The refrigerator air duct structure of claim 2 , wherein a ratio of the cross-sectional area of the first branch groove to the cross-sectional area of the second branch groove is 0.7:1-1.5:1.
6 . The refrigerator air duct structure of claim 1 , wherein a side of the refrigerator inner liner is provided with a sunk groove for the cover plate to lean against.
7 . The refrigerator air duct structure of claim 6 , wherein the thickness of the cover plate is 0.5 mm-3 mm.
8 . A refrigerator refrigerating air duct, comprising the refrigerator air duct structure of claim 1 .
9 . The refrigerator refrigerating air duct of claim 8 , wherein the cover plate is provided with a plurality of through-holes, which are arranged in the direction from the main groove to the branch grooves and increase in size.
10 . A refrigerator, comprising a refrigerating inner liner and a freezing inner liner, wherein the refrigerating inner liner is provided with the refrigerator refrigerating air duct of claim 8 therein; and/or
the freezing inner liner is provided with a refrigerator freezing air duct therein, the refrigerator freezing air duct comprises the refrigerator air duct structure of claim 1 .
