Hot water disinfection drinking system

Abstract

The invention discloses a hot water disinfection type water drinking system, which comprises a hot tank, a heat exchanger, a first pipeline switching valve, a second pipeline switching valve, a water outlet valve, a bypass pipeline and an electric control device, wherein a high temperature water inlet of the heat exchanger is communicated with a water outlet of the hot tank, a temperature lowering water outlet is communicated with an inlet of a water outlet valve, a normal-temperature water inlet is connected with a water source, a temperature-raising water outlet is communicated with a water inlet of the hot tank, the first pipeline switching valve is arranged on a pipeline between the water outlet of the hot tank and a high-temperature water inlet of the heat exchanger, or is arranged on a pipeline between the temperature-lowering water outlet of the heat exchanger and an inlet of a water outlet valve, one end of the bypass pipe is communicated with an inlet of the water outlet valve, the other end of the bypass pipe is communicated with the water outlet of the hot tank, and the second pipeline switching valve is arranged on the bypass pipe. The hot water disinfection type water drinking system has the advantages that by arranging the pipelines, the water outlet pipeline and the water outlet valve of the water drinking system can be periodically disinfected by high-temperature hot water, the qualified sanitation index of total amount of bacteria of flowing water of the water drinking system is guaranteed, and the sanitation and safety properties of water drinking are improved.

Description

Technical field [0001] The invention relates to a hot water disinfection drinking water system. Background technique [0002] At present, drinking water dispensers are already commonly used products. The basic function of drinking water dispensers is to divide water, that is, to distribute drinking water to facilitate users to access. The additional function is to adjust the temperature of drinking water, such as cooling and heating functions, and There are products that integrate the purification function. For example, the drinking water platforms used in some schools are actually drinking fountains with purification and heating functions. This kind of water dispenser is specially designed for school students. Considering that it can meet the requirements of multiple people to fetch water at the same time, it is usually equipped with several taps. For example, a machine is equipped with 6 faucets, and the heating power is relatively large. Taking into account the need to prev...

Problems solved by technology

[0003] However, after the hot water flowing out of the hot tank passes through the heat exchanger to release heat, its temperature often drops to about 35°C, and then flows to the outlet tap, and the water temperature may further drop to about 30°C, which is the best temperature for bacteria to multiply On the other hand, the faucet is directly connected to the atmosphere, and the water outlet is often in a wet state. Bacteria in the air can easily touch the wet water outlet, and stay and multiply there. The total number of bacteria in the water flowing out of the tap is basically unqualified, especially in summer, the total number of bacteria may exceed the standard by many times
