Many people have seen energy-saving direct drinking machines in public places, and many people worry that some energy-saving direct drinking machines in daily life are gradually replaced by bottled water because of repeated circulation of water, resulting in "yin and yang water" and "thousand boiling water". We changed the internal structure of the energy-saving water dispenser. On the one hand, through gradual water supply and interlayer heating technology, the emergence of yin and yang water and thousand boiling water is overcome; On the other hand, the shortcomings of traditional energy-saving drinking fountains are changed by the following methods. Heat exchange technology is to let hot water flow through the heat exchanger to release energy and cool it into warm water, so that it can absorb heat and preheat it to a temperature close to that of boiling water before entering the energy-saving water dispenser, which greatly saves the electricity and time needed for boiling water.
Although the initial investment of energy-saving drinking fountains is more than that of ordinary drinking fountains, its low-carbon and environmental-friendly characteristics greatly reduce the later use cost and allow users to drink healthy drinking water. This energy-saving water dispenser is especially suitable for schools, hospitals, enterprises, stations and other public places.
