Abstract

The invention relates to an intelligent control method for outlet water temperature of an instant heating body. A single chip microcomputer and a temperature sensor R0 are included in the method, and the temperature sensor R0 is mounted at the bottom of a water storage container and connected with the single chip microcomputer. The single chip microcomputer detects water storage container temperature T0(t) of the temperature sensor R0 every fixed time, known water density is rho, specific heat capacity of water is C, internal resistance of the instant heating body is R, heat conversion efficiency of the instant heating body is K, outlet water flow of the instant heating body is set as Q, outlet water temperature is T2(t), a formula of Cx(T2(t)-T0(t))xrhoxQ=KxP is obtained according to a heat balance principle, wherein P refers to heating power of the instant heating body, P=PWMxV<2>/R, PWM refers to duty ratio of heating, V refers to power supply voltage, and accordingly a formula of Cx(T2(t)-T0(t))xrhoxQ=KxPWMxV<2>/R is obtained, and a formula of PWM=Cx(T2(t)-T0(t))xrhoxQxR/(KxV<2>) is obtained finally. The method has the advantages that control variable is computed based on inlet water temperature and outlet water temperature, so that processing of experience nature is avoided, and control of the instant heating body is achieved in theory.

Description

technical field [0001] The invention relates to an intelligent control method for a high-power instantaneous heating body. Background technique [0002] For grinder coffee machines, instant drinking water equipment or instant electric water heaters, high-power instant heating bodies are used, which can realize immediate heating from cold water to hot water. In order to achieve the effect of instant heating, the instant heating body is configured with high power. Due to the large power, the temperature changes quickly, and the temperature data obtained by the traditional temperature measurement sensor has a long delay time. At the same time, due to the temperature sensor It cannot be in direct contact with water, and must be isolated by hygienic qualified materials in the middle, which will increase the delay time of data. Due to the delay of the detection data, the temperature of the outlet water will fluctuate greatly, which brings great difficulty to the development and d...
