背景技术Background technique
为了满足用户的用冰需求，有的冰箱配置了制冰机。为了方便用户获取冰块，有些冰箱将制冰机布置在了冰箱门上，以使用户在不打开冰箱门的情况下获取到冰块。In order to meet users' ice needs, some refrigerators are equipped with ice makers. In order to facilitate users to obtain ice cubes, some refrigerators have an ice maker placed on the refrigerator door so that users can obtain ice cubes without opening the refrigerator door.
但是现有冰箱在用户取冰时的趣味性较差，而且在昏暗的环境中不利于用户取冰。例如，用户夜间取冰时，需要先开灯，才能将取冰容器与冰箱上的取冰口对准。However, the existing refrigerator is less interesting for users to take out ice, and it is not conducive for users to take out ice in a dark environment.
