Abstract

The present invention provides a refrigerator, comprising a storage compartment and a mixed air passage. Both ends of the mixed air passage have air inlets, the middle portion of the mixed air passage comprises a mixed air outlet communicating with the storage compartment, and the mixed air passage is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet. The refrigerator of this invention comprises a mixed air passage, so that the air in an area of the storage compartment with a relatively high temperature can enter the mixed air passage earlier than external air or the air in the storage compartment with a relatively low temperature. Then, the two air flows are blown to the storage compartment in a mixed manner, realizing even temperature distribution in the storage compartment.

First claim

What is claimed is:

1. A refrigerator, comprising:
a storage compartment;
a mixed air passage, whose both ends have air inlets, whose middle portion comprises a mixed air outlet communicating with the storage compartment, and which is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet;
a mixed air blower configured to blow the two air flows to the storage compartment in a mixed manner; and
a mixed air passage cover plate mounted at a top wall of the storage compartment to form the mixed air passage, wherein the mixed air passage extends longitudinally and comprises the air inlets at its front and rear ends, wherein the mixed air passage cover plate is mounted on a lower surface of the top wall of the storage compartment, and comprises: a web portion extending upwards from a rear end of the web portion to a front end thereof and comprising a through hole at the center thereof, and an air aperture portion extending downwards in a direction perpendicular with the web portion from an edge of the through hole and having a lower end opening acting as the mixed air outlet.

2. The refrigerator of claim 1 , wherein the mixed air blower is an axial blower and is mounted inside the air aperture portion.

3. The refrigerator of claim 1 , wherein an included angle between the web portion and the horizontal plane is between 5 and 30 degrees.

4. The refrigerator of claim 1 , further comprising: a drawer which is mounted inside the storage compartment and lower portions of whose front and rear walls comprise ventilation holes.

5. The refrigerator of claim 1 , further comprising: a refrigeration air passage, wherein one air inlet of the mixed air passage is configured to receive a refrigeration air flow blown from the refrigeration air passage, and another air inlet of the mixed air passage communicates with the storage compartment.

6. The refrigerator of claim 5 , further comprising: a refrigeration air passage cover plate mounted at a front surface of a rear wall of the storage compartment to form the refrigeration air passage, and provided with at least one rear air outlet; or a refrigeration air passage cover plate mounted at a rear surface of the rear wall of the storage compartment to form the refrigeration air passage, the rear wall of the storage compartment being provided with at least one rear air outlet; wherein
the at least one rear air outlet is configured to blow the refrigeration air flow to the one air inlet of the mixed air passage and/or to the storage compartment; and
the another air inlet of the mixed air passage communicates with a front space of the storage compartment.

7. The refrigerator of claim 5 , wherein a lower portion of the rear wall of the storage compartment comprises a return air opening such that a part or all of the air in the storage compartment flows out of the storage compartment via the return air opening and enters the refrigeration air passage after being cooled.
