[0002] In drinking water equipment such as pipeline machines and water purifiers, heaters are an indispensable component. Common heating methods include heat storage type and instant heating type. The heater of heat storage type drinking water equipment is usually a hot tank (also called a hot tank), and the heater of instant hot water equipment is usually an instant heating tube.

[0003] Medium-temperature water may contain harmful bacteria without high-temperature treatment, so an additional sterilizer is required to sterilize and disinfect it. Currently, the medium-temperature water of commercial water dispensers with medium-temperature water function on the market comes out of the hot tank and is sterilized by an over-flow sterilizer before flowing out from the water outlet. For details, please refer to the Chinese patent "A water dispenser with good adaptability" with patent application number 202123455866.6.

[0004] However, in the above scheme, the heating function and the sterilization function are divided into two components for functional realization. On the one hand, the water circuit is complicated, and the mercury lamp sterilizers on the market are all made of stainless steel shell, glass cover and sealing ring. The shell is very large, which leads to extremely high cost. In addition, there are four water leakage points due to one inlet and one outlet of the pipe. On the other hand, the sterilizer needs to be started for sterilization every time water comes out, which consumes a lot of electricity. Utility Model Content
