Green direct drinking machine capable of recovering whole sensible heat

Abstract

The invention relates to an environment-friendly direct drinking water machine which can recycle all sensible heat; during the process that upper water is heated to 100-200 DEG C for sterilizing to become drinking water, a closed-circuit caloric content cycle, which is formed by 1-40 DEG C small temperature difference heat exchange technology, is adopted for producing the drinking water, the temperature of which is higher than that of the upper water by 1-40 DEG C, and 50-99% of sensible heat is recycled in total; therefore, only by compensating 1-50% of sensible heat loss and heat loss in the systemic circulation through heating, 20-1000 liters of drinking water can be produced by one kwh of electricity, the coefficient of performance of the drinking water machine can reach 80, which is 100 times of the traditional electric kettle for boiling water (100 DEG C); therefore, the drinking water machine is the most energy-saving product in the world in the 21st century.

Description

(1) Technical field [0001] The invention relates to a green direct water dispenser which recovers all sensible heat. (2) Background technology [0002] The traditional electric kettle / stove boils water, and each ton of 25°C urban tap water (hereinafter referred to as "Shangshui") needs to consume 87 degrees of electricity to boil to 100°C, which has the following disadvantages: [0003] 1. Since all the sensible heat from 25°C to 100°C is played back to the environment, an open-circuit enthalpy process is formed, which not only increases the operating cost, but also causes a huge waste of energy; moreover, it must be equipped with a high-power electric heater and an insulated water storage tank, which increases the initial investment ; [0004] 2. Go through 5 steps before drinking: (a) connect the water to the electric kettle; (b) heat the water in the electric kettle to 100°C; (c) pour the drinking water into a thermos / box to keep it warm; (d) pour the insulated drinking ...

AI Technical Summary

Problems solved by technology

[0005] 3. Drinking water at a temperature of 60-100°C in each step can easily burn children and the elderly, so there are potential safety hazards;

[0006] 4. The various transfer steps after boiling and before drinking are in contact with multiple appliances such as insulated water storage tanks and the atmosphere, which may easily cause secondary pollution of drinking water
