Description

Technical Field

[0001] This utility model relates to the field of hot beverage cooling technology, specifically a quick-cooling water dispenser. Background Technology

[0002] Direct drinking water systems have a wide range of applications. In public places such as parks, commercial complexes, and airports, the installation of direct drinking water machines not only facilitates the drinking water needs of citizens and tourists but also improves the service quality of public facilities. Furthermore, the most suitable drinking water temperature for direct human consumption is generally 45°C, and several 45°C water dispensing processes are currently available on the market. Details are as follows:

[0003] 1. Special heating elements are used, such as instantaneous thick-film heating or instantaneous nanofilm heating. When water flows through the heating element, it can be heated to 45 degrees Celsius in a very short time. This technology can achieve instantaneous heating and quickly produce hot water, but it does not reach the boiling point.

[0004] 2. Another method is to heat the water to boiling using a heating element and then cool it down with a fan, but this method takes a long time to cool down and the effect is not obvious.

[0005] 3. By combining different pipes, cold water is used to cool the heated hot water, but this method is not sustainable and the temperature drops slowly or not at all.

[0006] 4. The kettle process involves a temperature sensor monitoring the water temperature in real time and transmitting the signal to the control circuit. The water is first heated to 100 degrees Celsius, then cooled to 45 degrees Celsius at room temperature for 2-3 hours before being dispensed through the water dispensing control system. This process is too time-consuming, resulting in long wait times for consumers. Summary of the Invention
