Ice maker for a domestic refrigeration device

Abstract

An ice maker for a domestic refrigeration device includes an ice-making tray having a plurality of freezing cavities which are divided between multiple cavity rows arranged one behind the other in a first tray extension direction. Freezing cavities arranged adjacent to one another in pairs in the first tray extension direction are separated on a tray underside of the ice-making tray by an indentation. The ice maker also includes a wall element for delimiting, in a freezing operating position of the wall element relative to the ice-making tray, a cold air channel between the underside of the ice-making tray and the wall element, which cold air channel extends substantially over the entire length of the ice-making tray in the first tray extension direction. The wall element is designed with at least one air-deflecting formation which projects locally into the cold air channel.

1 . An ice maker for a domestic refrigeration device, comprising:
 an ice-making tray having a plurality of freezing cavities which are divided between a plurality of cavity rows arranged one behind the other in a first tray extension direction, wherein freezing cavities that are arranged adjacent to one another in pairs in the first tray extension direction are separated on a tray underside of the ice-making tray by an indentation;   a wall element for delimiting a cold air channel which, in a freezing operating position of the wall element relative to the ice-making tray, extends between the underside of the ice-making tray and the wall element substantially over the entire length of the ice-making tray in the first tray extension direction thereof,   wherein the wall element is designed with at least one air-deflecting formation which projects locally into the cold air channel and which, in the freezing operating position of the wall element and when seen in a normal projection onto the ice-making tray, is situated in a region of the ice-making tray that contains the freezing cavities and which has an extension transverse to the first tray extension direction.   
     
     
         2 . The ice maker as claimed in  claim 1 , wherein the at least one air-deflecting formation comprises multiple air-deflecting formations which are arranged spaced apart from one another and one behind the other in the first tray extension direction. 
     
     
         3 . The ice maker as claimed in  claim 1 , wherein each of the at least one air-deflecting formations is situated, in the freezing operating position and when seen in the normal projection onto the ice-making tray, at least in part in a region between two adjacent cavity rows in the first tray extension direction, in particular between two adjacent freezing cavities in the first tray extension direction. 
     
     
         4 . The ice maker as claimed in  claim 1 , wherein the at least one air-deflecting formation comprises an air-deflecting formation in association with each of multiple cavity pairs of the ice-making tray that are adjacent in the first tray extension direction. 
     
     
         5 . The ice maker as claimed in  claim 1 , wherein the at least one air-deflecting formation comprises an air-deflecting formation only in association with a partial number of all the cavity pairs of the ice-making tray that are adjacent in the first tray extension direction. 
     
     
         6 . The ice maker as claimed in  claim 5 , wherein the at least one air-deflecting formation comprises an air-deflecting formation only in association with such a cavity pair whose freezing cavities are arranged downstream of a first cavity row located proximate to an inflow side of the cold air channel. 
     
     
         7 . The ice maker as claimed in  claim 5 , wherein the at least one air-deflecting formation comprises an air-deflecting formation only in association with such a cavity pair whose freezing cavities are arranged upstream of a last cavity row located proximate to an outflow side of the cold air channel. 
     
     
         8 . The ice maker as claimed in  claim 1 , wherein the at least one air-deflecting formation forms at least one shovel- or ramp-shaped air-deflecting surface which projects locally into the cold air channel, in order to deflect inflowing cold air in the direction towards the indentation between one of the cavity pairs. 
     
     
         9 . The ice maker as claimed in  claim 1 , wherein the wall element is designed downstream of at least one and in particular of each air-deflecting formation with a local, in particular completely surrounded, wall aperture. 
     
     
         10 . The ice maker as claimed in  claim 1 , wherein the at least one air-deflecting formation comprises an air-deflecting formation which in the freezing operating position of the wall element—when seen in the normal projection onto the ice-making tray—extends perpendicular to the first tray extension direction over a length that corresponds at least to half of the extension, measured in that direction, of the ice-making tray. 
     
     
         11 . The ice maker as claimed in  claim 1 , comprising a support structure, which rotatably mounts the ice-making tray, in particular encloses the ice-making tray in the manner of a frame, for installation in the refrigeration device, wherein the wall element is mounted on the support structure so as to be movable relative thereto.
