Embodiment 1

[0023] A kind of sterilization system of electric heating water dispenser provided in this embodiment, such as figure 1 As shown, the sterilization system is set inside the electric water dispenser, including a heat exchanger, a heating tank and several water pipes. The heat exchanger is composed of an inner pipe and an outer pipe sleeved on the inner pipe. The inlet and outlet of the inner pipe are reversely set. A 12V three-way solenoid valve is installed at the water inlet of the heat exchanger outer pipe. The water inlet of the three-way battery valve is connected to the tap water pipe externally. Connect the water inlet of the outer pipe of the heat exchanger, and the outlet of the outer pipe of the heat exchanger is connected to the heating water tank through the water pipe. The other water outlet of the battery valve is connected to the four-point copper tee through a water pipe, and the heated water bladder is connected to the water inlet of the inner tube of the heat ...

Embodiment 2

[0025] This embodiment provides a sterilization method for the sterilization system of the electric heating water dispenser in the embodiment, which specifically includes the following steps:

[0026] (1) In the normal working state of the electric water dispenser, the three-way battery valve and the four-point copper three-way in front of the heater are closed, and the three-way solenoid valve is connected to the water inlet of the outer tube of the heat exchanger, so that the external cold tap water passes through The outer tube of the heat exchanger enters the heater to be heated, and the heated tap water is connected to the water inlet of the inner tube of the heat exchanger through the four-way temperature control valve, so as to keep the flow direction of the hot tap water and the cold tap water in the opposite direction, and the hot tap water passes through the hot tap water. The inner pipe of the exchanger drains to the tap for drinking;

[0027] (2) When the water pip...

Abstract

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.

Description

technical field [0001] The invention relates to a sterilization system and a sterilization method thereof, in particular to a sterilization system and a method in an electric heating water dispenser, and belongs to the technical field of safe drinking water. Background technique [0002] With the rapid development of urbanization and industrialization, a large amount of industrial "three wastes", urban sewage and garbage, and chemical fertilizers and pesticides widely used in rural areas are discharged into rivers, rivers, lakes, seas, and penetrate into the ground in different ways, polluting the water source environment It is becoming more and more serious, especially the increasing pollution of organic matter. The pollution of drinking water sources has become a worldwide problem. The problem of water quality and water shortage caused by environmental pollution is becoming more and more prominent. People are eager to drink guaranteed, high-quality safe water. , pure water...
