Refrigerator

Abstract

A refrigerator supplies cool air generated by a cooler to a plurality of storage compartments by cooling fan ( 27 ). Cooling fan ( 27 ) is formed of multi-blade fan ( 27 a ) which blows cool air in a circumferential direction. Guide case ( 33 ) of cooling fan ( 27 ) has discharge opening portion ( 35 ) which supplies cool air to the plurality of storage compartments at one portion.

         4 . The refrigerator according to  claim 3 , wherein
 a portion of the integrally formed case which covers an outer periphery of the cooling fan is formed in an Archimedean spiral form.   
     
     
         5 . A wine cellar for preserving wines, the wine cellar comprising:
 a lower storage compartment;   an upper storage compartment located upper than the lower storage compartment in the wine cellar;   a cooling compartment located closer to a back surface of the wine cellar than the lower storage compartment and the upper storage compartment;   a cooler disposed in the cooling compartment;   a wall surface unit that partitions an inside of the refrigerator into the cooling compartment and a set of the lower storage compartment and the upper storage compartment, the wall surface unit having a first surface facing the cooling compartment, a second surface facing the lower storage compartment, and a third surface facing the upper storage compartment;   a cooling fan disposed on the first surface of the wall surface unit, the cooling fan being configured to supply cool air generated by the cooler in a circumferential direction;   a damper device disposed on the first surface of the wall surface unit, the damper device having at least a first opening portion for supplying the cool air to the lower storage compartment, and a second opening portion for supplying the cool air to the upper storage compartment;   a first blow-off port that is formed in the second surface of the wall surface unit, the first blow-off port being configured to supply cool air to the lower storage compartment;   a second blow-off port that is formed in the third surface of the wall surface unit, the second blow-off port being configured to supply cool air to the upper storage compartment;   a first discharge air passage that is formed in the wall surface unit, the first discharge air passage allowing the first opening portion and the first blow-off port to communicate with each other; and   a second discharge air passage that is formed in the wall surface unit, the second discharge air passage allowing the second opening portion and the first blow-off port to communicate with each other.   
     
     
         6 . The wine cellar according to  claim 5 , wherein
 the damper device is disposed above the cooling fan.   
     
     
         7 . The wine cellar according to  claim 6 , wherein
