Problems solved by technology

Therefore, public water dispensers need to be equipped with cooling boiling water devices and corresponding water storage devices, but the temperature of warm water is suitable for the growth and reproduction of bacteria. Especially in spring and summer, the growth of bacteria will pollute the water quality, and even the excessive number of harmful bacteria will make drinking water personnel sick
Therefore, the disinfection device in the public water dispenser is very important. The existing water dispenser disinfection methods mainly include ozone sterilization, ultraviolet sterilization, filter sterilization, etc. Ozone sterilization is a bacteriolysis-level method, and the sterilization is thorough. It can damage a variety of items, and most of the devices inside the water dispenser are

Embodiment 1

[0026] The solenoid valve is automatically controlled, the first solenoid valve and the normally open solenoid valve are closed, the second solenoid valve is opened, so that a closed loop is formed between each device and the water pipe, and the circulation pump is turned on, so that the pure water begins to be circulated, and the pure water in the water inlet pipe reaches the medium. The water is transported to the heater for heat treatment, and the purified water after heat treatment is transported to the heat exchanger, so that the water temperature of each pipe in the heat exchanger is at least 80°C, and the hot water treated by the heat exchanger is transported to the outlet pipe, Pasteurize the outlet pipe, transfer the hot water in the outlet pipe to the water inlet pipe, and pasteurize the water inlet pipe. The cycle sterilization time is at least 2 minutes. The valve is opened, and the second solenoid valve is closed, so that the hot water in the circulation circuit is...

Embodiment 2

[0029] Manually control the solenoid valve, close the first solenoid valve and the normally open solenoid valve, and open the second solenoid valve to form a closed loop between each device and the water pipe, and turn on the circulation pump to start the circulation of pure water. The purified water is delivered to the heater for heat treatment, and the heated purified water is delivered to the heat exchanger, so that the water temperature of each pipe in the heat exchanger is at least 80°C, and the hot water treated by the heat exchanger is delivered to the outlet water Pipeline, pasteurize the outlet pipe, transport the hot water in the outlet pipe to the water inlet pipe, and pasteurize the water inlet pipe. The cycle sterilization time is at least 2 minutes, open the normally open solenoid valve, and disinfect the faucet. After the cycle disinfection is finished, the first solenoid valve and the normally open solenoid valve are opened, and the second solenoid valve is clos...

Abstract

The invention relates to a self-disinfecting device for a large-scale stainless steel water dispenser and a disinfection process thereof. The self-disinfecting device comprises a heater and a heat exchanger between which a water pipe is arranged, and a water inlet pipeline is arranged at an opening A1 of the heat exchanger; a water outlet pipeline is arranged at an opening A4; taps are arranged on the water outlet pipeline; a circulating pipeline is connected between the water outlet pipeline and the water inlet pipeline so that a circulation loop is formed; and a circulating pump is arranged on the circulating pipeline. The self-disinfecting device is simple, achieves a good disinfection effect through high-temperature disinfection and is short in disinfection time; solenoid valves are adopted to control switching between circulatory disinfection and normal water supply, so that the switching is convenient; the operation is stable, the later-period operation and maintenance are convenient and the cost is low.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a self-disinfection device for a large stainless steel water dispenser and a disinfection process thereof. Background technique [0002] At present, public water dispensers are provided in many densely populated public places. These public water dispensers are located in stations, hospitals and schools, and need to provide a large amount of warm water for instant drinking. Therefore, public water dispensers need to be equipped with cooling boiling water devices and corresponding water storage devices, but the temperature of warm water is suitable for the growth and reproduction of bacteria. Especially in spring and summer, the growth of bacteria will pollute the water quality, and even the excessive number of harmful bacteria will make drinking water People get sick. Therefore, the disinfection device in the public water dispenser is very important. The existing water dispenser disinfection ...
