In addition to pure water products, there are also water products with rich product functions. Among them, the concept of boiled water (i.e. cooked water) is deeply rooted in the hearts of Chinese people and may become the next selling point for water purification.

[0003] However, for people who like to drink cold water, directly cooling the filtered water before drinking, or using the water again after not using it for a long time, the influence of water stored in the pipes will cause the bacterial count in the water to seriously exceed the standard, thus affecting their health.

[0050] The utility model also provides a cooked water preparation method, which is applicable to the above-mentioned cooked water preparation system. When the cooked water preparation system is operated to end water preparation, the cooked water preparation method includes: closing the refrigeration module 4 of the cooked water preparation system; controlling the outlet of the heating pipeline 3 of the cooked water preparation system and the inlet of the internal heat exchange pipeline 11 of the cooked water preparation system to be in a disconnected state; controlling the outlet of the heating pipeline 3 and the inlet of the water outlet pipeline 5 of the cooked water preparation system to be in a conducting state; and opening the first heating component 20 of the cooked water preparation system and the second heating component 31 of the cooked water preparation system to discharge the accumulated water in the cooked water preparation system through the outlet of the water outlet pipeline 5 in the form of water vapor.

[0058] Compared with the prior art, the above method can add the function of producing cooked cold water to the whole machine due to the addition of the refrigeration module 4.

[0059] When the cooked water preparation system finishes refrigeration and water intake, since there is accumulated water in the refrigeration pipes and the heat exchange module, not taking water for a long time will lead to the growth of bacteria. After turning off the refrigeration module, turn off the water purification micro pump 216, turn on the two first heating components 20 and the second heating components 31, and the water vapor generated within a certain period of time can be used to discharge the accumulated water in the cooked water preparation system in the form of water vapor. In this process, the water vapor can be used to perform high-temperature disinfection on the entire pipeline of the cooked water preparation system, so that the purpose of discharging the accumulated water and disinfection can be achieved to the greatest extent, reducing the growth of bacteria in the cooked water preparation system, which is more conducive to the hygiene and safety of drinking water.
