Refrigeration display cabinet

Abstract

The present utility model proposes a refrigeration display cabinet, comprising: a cabinet; a display rack fixed inside the cabinet; an air channel arranged at least partially surrounding the display rack; a partition mounted in the air channel to separate the air channel into an inner air channel and an outer air channel, wherein the partition is provided with an opening for connecting the inner air channel and the outer air channel; an evaporator arranged in the inner air channel, wherein the side of the evaporator is located at or near the opening; and a damper assembly fixed at the opening of the partition, wherein the damper assembly is capable of opening or closing the opening. The refrigeration display cabinet according to the present utility model can defrost the evaporator simultaneously from the bottom and side thereof during the defrosting mode, thus improving defrosting efficiency.

What is claimed is: 
     
         1 . A refrigeration display cabinet, comprising:
 a cabinet;   a display rack, fixed inside the cabinet;   an air channel, arranged at least partially surrounding the display rack;   a partition, mounted in the air channel to separate the air channel into an inner air channel and an outer air channel, wherein the partition is provided with an opening for connecting the inner air channel and the outer air channel;   an evaporator, arranged in the inner air channel, wherein a side of the evaporator is located at or near the opening; and   a damper assembly, fixed at the opening of the partition, wherein the damper assembly is capable of opening or closing the opening.   
     
     
         2 . The refrigeration display cabinet according to  claim 1 , wherein the damper assembly comprises a plurality of wind deflectors, where the plurality of wind deflectors are rotatably fixed at the opening, and the plurality of wind deflectors synchronously open or close the opening by means of a linkage mechanism. 
     
     
         3 . The refrigeration display cabinet according to  claim 2 , wherein the plurality of wind deflectors comprise a first wind deflector, a second wind deflector, and a third wind deflector, where the first wind deflector is arranged at or near the top of the evaporator, the second wind deflector is arranged in or near the middle of the evaporator, and the third wind deflector is arranged at or near the bottom of the evaporator. 
     
     
         4 . The refrigeration display cabinet according to  claim 3 , wherein a length of the second wind deflector is the same as that of the third wind deflector, and lengths of the second wind deflector and the third wind deflector are less than a length of the first wind deflector. 
     
     
         5 . The refrigeration display cabinet according to  claim 3 , wherein widths of the first wind deflector, the second wind deflector, and the third wind deflector are the same as a width of the outer air channel in the horizontal direction. 
     
     
         6 . The refrigeration display cabinet according to  claim 4 , wherein the length of the first wind deflector is less than a length of the outer air channel in the horizontal direction. 
     
     
         7 . The refrigeration display cabinet according to  claim 3 , wherein the first wind deflector, the second wind deflector, and the third wind deflector are made of metal or plastic. 
     
     
         8 . The refrigeration display cabinet according to  claim 1 , wherein a shape of the opening is consistent with a shape of the side of the evaporator. 
     
     
         9 . The refrigeration display cabinet according to  claim 3 , wherein the first wind deflector, the second wind deflector, and the third wind deflector are controlled by a stepper motor controller. 
     
     
         10 . The refrigeration display cabinet according to  claim 1 , wherein the damper assembly is fixed at the opening of the partition by bolts. 
     
     
         11 . The refrigeration display cabinet according to  claim 1 , wherein the refrigeration display cabinet further comprises a fan arranged at or near the bottom of the partition.
