桶装水装在桶里就安全吗？
Is barreled water safe in a bucket?
饮水机还要定期清洁，虽然没必要每换一次桶就全面清洁一次，但是，每个月做一次清洁工作是良好卫生习惯的体现。需要注意的是，清洁饮水机的清洁剂毕竟是化学制剂，所以一定要冲洗干净后再饮用。另外，桶装水尽量10天内饮用完毕。
The water dispenser needs to be cleaned regularly. Although it is not necessary to clean it completely every time the bucket is changed, it is a reflection of good hygiene habits to do cleaning once a month. It should be noted that the detergent used to clean the water dispenser is chemical after all, so it must be rinsed before drinking. In addition, the bottled water should be drunk within 10 days.
