背景技术Background Art
制冰机是利用制冷系统来产生冰块的设备，产生的冰块可用于食品冷藏保鲜，给饮料降温等等，常规制冰机往往为间歇式的，即制冰过程和冰块脱模过程依次进行。冰块脱模需要额外热量，可以采用电加热或热制冷剂的方式，其中热制冷剂脱模具有更省电的特点，而目前尚未有利用冰块脱模时消耗的冷量提高制冰机的运行效率且实现连续式制冰的高效制冰机。Ice makers are devices that use a refrigeration system to produce ice cubes. The ice cubes produced can be used to keep food fresh, cool beverages, etc. Conventional ice makers are often intermittent, that is, the ice making process and ice demolding process are carried out in sequence. Ice demolding requires additional heat, which can be done by electric heating or hot refrigerant. Among them, hot refrigerant demolding has the characteristic of saving more electricity. However, there is currently no efficient ice maker that uses the cold energy consumed when demolding ice cubes to improve the operating efficiency of the ice maker and achieve continuous ice making.
