The refrigerating apparatus as recited in claim 4, wherein the refrigerating return pipe further has a branch pipe (713) extending from the main pipe (711), the connecting pipe (712) and the branch pipe (713) are disposed on both sides of the main pipe, and when the blower is in normal operation, air in the refrigerating chamber flows into the cooling chamber through the branch pipe and the main pipe, and when the blower is out of operation, cooled air in the cooling chamber flows into the lower portion of the refrigerating chamber through the branch pipe and the main pipe.

6. The refrigeration apparatus as recited in claim 5, wherein the auxiliary return air inlet (7103) of the branch duct (713) and the return air inlet (7102) of the main duct (711) are disposed at intervals in the height direction.

7. The refrigerating apparatus as recited in claim 1, further comprising a mixing chamber (301) for communicating the cooling chamber (20) with the refrigerating chamber (11), and an air duct (75) provided at a rear portion of the storage space of the refrigerating chamber (11), wherein one end of the air duct (75) communicates with the mixing chamber (301) and the other end of the air duct is disposed opposite to the mixing chamber (301) and communicates with the storage space of the refrigerating chamber (11).

8. A refrigerating apparatus as claimed in claim 7, wherein a drawer (14) is provided in the refrigerating chamber (11) at a lower portion thereof and a support structure (15) is provided at an upper portion thereof for supporting articles, and a return air inlet (7102) of the refrigerating return air duct (71) is provided near the drawer (14) at a lower side thereof.

9. The refrigerating apparatus as recited in claim 7, further comprising a mixing structure (30) provided at a rear portion of the refrigerating chamber (11), wherein, when the blower (22) is operated normally, the air cooled in the cooling chamber (20) and the air in the refrigerating chamber (11) flow into a mixing chamber (301) formed by the mixing structure (30) to be mixed and then flow out into the refrigerating chamber (11).

10. The refrigerating apparatus as recited in claim 9, wherein the air mixing structure (30) is disposed at a position on the back of the refrigerating chamber (11) and is provided with an air outlet (312) at the front side thereof for discharging air forward, an air inlet duct (5) for introducing air in the refrigerating chamber (11) into the interior of the mixing chamber (301), and a communication port at the lower side thereof and communicating with the air guide duct (75).
