Description

An ice-making double-duct system and refrigerator

technical field

The utility model relates to the technical field of refrigerator ice making, in particular to an ice making double air duct system and a refrigerator.

Background technique

Existing refrigerator structure is an upper refrigerating chamber, left and right side-by-side doors, and the bottom is a freezing chamber 102, usually one to two drawers in the freezing chamber 102. As shown in Figure 1, the ice-making compartment is arranged on the refrigerator door 103. There are an ice maker 12 and an ice storage bucket 13 in the ice-making compartment. Air intake and return air from the freezing evaporator 3. Under normal circumstances, the refrigerating evaporator 21 and the freezing evaporator 31 of the existing refrigerator work alternately. When the freezing chamber 102 requests cooling, the freezing evaporator 31 starts to work. The cooled cold air is blown into the ice making chamber to maintain the ice making chamber at the set temperature (usually ≤-15°C) to meet the needs of ice making and ice storage.

Since the cold energy used in existing ice-making comes from the freezing evaporator, only when the freezing evaporator is working, the ice-making chamber can draw cold air from the freezing evaporator to make ice; The evaporators work alternately, so when the refrigerated evaporator is not working, there is no source of cold air in the ice making chamber, and the ice machine cannot work, which causes the ice machine to start up at a frequency that cannot reach 100%, and the ice production is low. In addition, since the freezing evaporator and the refrigerating evaporator of the refrigerator work alternately, when the freezing evaporator works, the temperature in the ice-making chamber decreases, and when the refrigerating evaporator works, the temperature in the ice-making chamber rises. When the ice-making chamber fluctuates for a long time and with multiple frequencies, the ice cubes in the ice storage bucket may melt and stick together, which will not only cause the shape and size of the ice cubes to change, but also make it difficult to get ice out, causing "ice jamming" and "ice freezing". block jam".
