[0027] Working principle: The temperature-regulating water system of this coffee machine is a real-time temperature-regulating system that allows the user to set the water temperature and output water at the set temperature for coffee extraction, saving waiting time.

[0028] Set the user-adjusted temperature to T0, where T0 is a known value. The formula for calculating the temperature after mixing hot and cold water is T0 = (m1*T1 + m2*T2) / (m1 + m2), where T0 represents the mixed water temperature, m1 and m2 are the masses of cold and hot water respectively, and T1 and T2 are the temperatures of the cold and hot water respectively. This formula is based on the principle of heat conservation, meaning the heat absorbed by the cold water equals the heat released by the hot water. In practical applications, if the specific heat capacities of the water are equal, this formula can be used directly. If the specific heat capacities are unequal, calculations need to be performed based on their respective specific heat capacities (C1 and C2).

[0029] The formula becomes T0=(m1*T1*C1+m2*T2*C2) / (m1+m2). This formula is applicable to calculating the temperature of water mixed with water of two different temperatures. It takes into account the mass and specific heat capacity of the water and is a general formula for calculating the temperature of mixed water. In practical applications, if the specific heat capacity of the water is equal, the simplified formula can be used for calculation.

[0030] Since the instantaneous or storage boiler in the water circuit system outputs a fixed temperature each time and has a temperature sensor to read the temperature, the hot water temperature is known. Similarly, the cold water temperature is the daily cold water, and there is a cold water sensor in the water circuit, which can also read the cold water temperature in real time. The amount of water required for each extraction can be determined by the user's choice of single cup or double cup, and the amount is also a known value, i.e., m0 = m1 + m2, which can be simplified to (T0 - t2) * m0 = (T1 - T2) m1.
