The invention discloses a sterilization
system of an
electric heating water dispenser. The sterilization
system comprises a
heat exchanger, a heater and a plurality of water pipes, wherein the
heat exchanger consists of an inner tube and an outer tube which are reverse in inlet and outlet, a three-way
magnetic valve is installed at the position of a water inlet of the outer tube of the
heat exchanger, one water outlet of the three-way
magnetic valve is connected with the water inlet of the outer tube of the heat exchanger, a water outlet of the outer tube of the heat exchanger is connected with the heater, a 15
millimeter copper three-way joint is arranged between the water outlet of the outer tube of the heat exchanger and the heater, the other water outlet of the three-way
magnetic valve is connected with the15
millimeter copper three-way joint, the heater is connected with a water inlet of the inner tube of the heat exchanger, a four-way
temperature control valve is arranged between the heater and the water inlet of the inner tube of the heat exchanger, a water outlet of the inner tube of the heat exchanger is connected with a faucet of the
electric heating water dispenser, a
copper three-way joint is arranged on a faucet interface
water pipe and is sequentially connected with a high-temperature drainage battery valve and a draining
pipe at the bottom of the
electric heating water dispenser. The invention further provides a sterilization method of the sterilization
system of the electric heating water dispenser. The problem that the
bacterial colony number of the electric heating water dispenser exceeds the standard is solved by means of the sterilization system, and the sterilization method of the sterilization system consumes short time and is low in cost.
