Waterway sterilization system, method, device and medium

The invention discloses a waterway sterilization system, method and device and a medium, and relates to the technical field of waterway sterilization, an ultraviolet sterilization lamp can only conduct sterilization at a water outlet and cannot conduct sterilization on a pipeline, when water in a water tank reaches the water amount capable of meeting all-waterway sterilization, a controller controls a first water pump to be started, and the first water pump is started; water in the water tank is pumped into the heater to be heated until a preset temperature value is reached, a second outlet of the one-inlet and two-outlet electromagnetic valve is controlled to be opened, the heated water flows into the electronic ice liner through the second outlet of the one-inlet and two-outlet electromagnetic valve to sterilize the electronic ice liner, and then the heated water flows back to the water tank through the electronic ice liner. And the controller controls the second water pump and the water outlet electromagne
