Refrigerator

Abstract

The present invention provides a refrigerator, comprising a storage compartment, a refrigeration air passage configured to supply refrigeration air and a top air passage. The top air passage is provided at a top wall of the storage compartment, comprises a rear end air inlet, a front end air inlet and a mixed air outlet opening downwards, and is configured to receive refrigeration air blown from the refrigeration air passage via the rear end air inlet, receive return air returning from the storage compartment via the front end air inlet, and allow the refrigeration air and the return air to flow into the storage compartment in a mixed manner via the mixed air outlet.

What is claimed is: 
     
         1 . A refrigerator, comprising:
 a storage compartment;   a refrigeration air passage configured to supply refrigeration air; and   a top air passage that is provided at a top wall of the storage compartment, comprises a rear end air inlet, a front end air inlet and a mixed air outlet opening downwards, and is configured to receive refrigeration air blown from the refrigeration air passage via the rear end air inlet, receive return air returning from the storage compartment via the front end air inlet, and allow the refrigeration air and the return air to flow into the storage compartment in a mixed manner via the mixed air outlet.   
     
     
         2 . The refrigerator of  claim 1 , wherein the refrigeration air passage communicates with a rear space of the storage compartment to supply refrigeration air to the storage compartment. 
     
     
         3 . The refrigerator of  claim 1 , further comprising:
 a cooling chamber provided with an air outlet connected with the refrigeration air passage;   a cooling device provided in the cooling chamber to cool the air passing the cooling chamber;   a blower provided at the air outlet of the cooling chamber; and   a return air passage connecting a lower space of the storage compartment and the cooling chamber, such that a part or all of the air in the storage compartment enters the cooling chamber via the return air passage and enters the refrigeration air passage after being cooled by the cooling device.   
     
     
         4 . The refrigerator of  claim 3 , further comprising:
 another storage compartment provided below the storage compartment and in front of the cooling chamber;   another refrigeration air passage connecting the air outlet of the cooling chamber and the another storage compartment; and   another return air passage connecting the another storage compartment and the cooling chamber.   
     
     
         5 . The refrigerator of  claim 3 , further comprising: a movable air supply hood provided at an outer side of the air outlet of the cooling chamber and configured to provide an opening allowing the refrigeration air to flow into the refrigeration air passage when closing the air outlet of the cooling chamber. 
     
     
         6 . The refrigerator of  claim 3 , further comprising: an air door configured to controllably close or open the refrigeration air passage. 
     
     
         7 . The refrigerator of  claim 1 , further comprising: a top blower configured to blow the refrigeration air and the return air to the storage compartment in a mixed manner via the mixed air outlet. 
     
     
         8 . The refrigerator of  claim 7 , further comprising: a top air passage cover plate mounted at a lower surface of the top wall of the storage compartment to form the top air passage. 
     
     
         9 . The refrigerator of  claim 8 , wherein the top air passage cover plate comprises:
 a web portion extending upwards from its rear end to its front end and provided with a through hole; and   an air aperture portion extending downwards from an edge of the through hole, having a lower end opening acting as the mixed air outlet, and having the blower mounted therein.   
     
     
         10 . The refrigerator of  claim 1 , further comprising: a refrigeration air passage cover plate mounted at a front surface of the rear wall of the storage compartment to form the refrigeration air passage, and provided with multiple refrigeration air outlets to provide the refrigeration air to the storage compartment and/or the top air passage.
