With the concept of health and environmental protection becoming more and more popular, the choice of kitchen appliances has also become a major theme. The market size of quick-dispenser water dispensers for kitchen appliances is gradually expanding. However, the reporter learned that due to the large differences with the structure of traditional drinking fountains, the detection of quick-dispenser water dispensers has always been based on the national standards for liquid heater products, although the development of the industry standard for hot drinking fountains in 2007 It has been started but it has not yet been introduced.

Zhang Yachen, deputy chief engineer of the China Household Electrical Appliances Research Institute, said that there are different opinions on the standard applicability of this type of product in the industry, and one opinion is that it should be applicable to IEC60335-2-35 (GB4706.11) for household and similar purposes. The special requirements for the safety of electric fast-fired water heaters for electrical appliances", and the other opinion should be applicable to IEC 60335-2-15 (GB4706.19) "Special requirements for safe liquid heaters for household and similar electrical appliances".
