Frost-free refrigeration appliance

Abstract

A refrigeration appliance, particularly a domestic refrigeration appliance, has a thermally-insulating housing in which at least one first and one second inner chamber are separated from one another by a thermally-insulated wall. The first inner chamber is divided into a storage compartment and an evaporator chamber. A passage in the thermally-insulated wall connects the evaporator chamber to the second inner chamber. At least one closure element for controlling the air exchange is housed, in the passage, between the evaporator chamber and the second inner chamber.

         16 . A refrigeration appliance, comprising:
 a thermally-insulated housing;   a thermally-insulated wall having a passage formed therein;   at least one first and one second inner chamber being separated from one another by said thermally-insulated wall in said thermally-insulated housing, said first inner chamber is divided into a storage compartment and an evaporator chamber and said passage in said thermally-insulated wall connecting said evaporator chamber to said second inner chamber; and   at least one closure element for controlling an air exchange is housed, in said passage, between said evaporator chamber and said second inner chamber.   
     
     
         17 . The refrigeration appliance according to  claim 16 , wherein said closure element has a flap. 
     
     
         18 . The refrigeration appliance according to  claim 17 , wherein said closure element has a frame which completely surrounds said flap in a closed position. 
     
     
         19 . The refrigeration appliance according to  claim 16 , further comprising an air channel cover, said second inner chamber is divided by said air channel cover into a further storage compartment and at least one air channel. 
     
     
         20 . The refrigeration appliance according to  claim 19 , wherein said at least one air channel is one of two air channels, a first of said air channels extends from said passage into a lower region of said second inner chamber and a second of said air channels extending from said passage past said lower region into an upper region of said second inner chamber. 
     
     
         21 . The refrigeration appliance according to  claim 20 , wherein said at least one closure element is assigned to each of said air channels. 
     
     
         22 . The refrigeration appliance according to  claim 21 , further comprising a motor for driving said at least one closure element, said at least one closure element combined with said motor forms a sub-assembly which is mounted in said passage. 
     
     
         23 . The refrigeration appliance according to  claim 19 ,
 wherein said thermally-insulated wall has a thermally insulating layer;   wherein said first inner chamber and said second inner chamber in each case are defined by an internal container each having an aperture formed therein; and   further comprising a tubular housing and in said passage said tubular housing extends between said apertures of said internal containers through said thermally insulating layer of said thermally-insulated wall.   
     
     
         24 . The refrigeration appliance according to  claim 23 , wherein said tubular housing has two flanges which in each case bear against said internal container of one of said first and said second inner chamber. 
     
     
         25 . The refrigeration appliance according to  claim 24 , wherein said tubular housing has two plug-connected housing parts each with one of said two flanges. 
     
     
         26 . The refrigeration appliance according to  claim 23 , further comprising a foamed part disposed between a rear face of said air channel and a rear wall of said internal container of said second inner chamber. 
     
     
         27 . The refrigeration appliance according to  claim 26 , wherein said air channel cover comes into contact with said foamed part on both sides of said air channel and said foamed part is fixed in position between said air channel cover and said rear wall. 
     
     
         28 . The refrigeration appliance according to  claim 16 , wherein said closure element is able to be inserted from sides of one of said first and said second inner chamber into said passage. 
     
     
         29 . The refrigeration appliance according to  claim 28 , further comprising a clamp, said closure element is secured by said clamp which is latched to said thermally-insulated wall between said closure element and said second inner chamber, said closure element being inserted from said second inner chamber. 
     
     
         30 . The refrigeration appliance according to  claim 22 , further comprising a clamp disposed so as to be positioned across said motor. 
     
     
         31 . The refrigeration appliance according to  claim 16 , wherein the refrigeration appliance is a domestic refrigeration appliance.
