Intelligent toilet bowl instantaneous heating system, device and control method

Abstract

The invention provides an intelligent toilet bowl instantaneous heating system, device and control method. The intelligent toilet bowl instantaneous heating system comprises a PID regulator, an actuator, an A / D converter, a D / A converter and a temperature sensor; the PID regulator is connected with the actuator through the D / A converter; the actuator is connected with a controlled object; a feedback loop is further arranged between the PID regulator and the controlled object, and the A / D converter is arranged on the feedback loop; and the temperature sensor is used for detecting the temperature of the heating system, the PID regulator is used for regulating heating power of the system according to the temperature, and the actuator is used for heating an intelligent toilet bowl according tothe heating power. With adoption of the technical scheme, the required regulating power is calculated through a PID control algorithm, through controlling assisting of a point speed limit curve, inlet water is heated rapidly and accurately according to the required power so that the heating device can be flexibly applied to the system with the changeable environment.

[0002] Cleaning is one of the main functions of electronic toilets. The temperature of the cleaning water is the intuitive temperature experience of electronic toilets. The control of cleaning heating temperature is related to the overall user experience and even personal safety; The complexity and diversity of , usage methods, etc. lead to the complexity and diversity of water temperature control; the internal design of the entire heating component is different, such as water flow design, temperature sensor position, heater power difference, etc., or the external use of the entire heating component Differences, such as differences in water inlet temperature, use time, frequency, etc., will lead to differences in cleaning effects; at present, when electronic toilet products use instantaneous heating devices, the heating speed is often too slow or the heating overshoot cannot be effectively suppressed, which affects the experience. situation, and the water temperature performance is different due to fluctuations in power supply voltage, fluctuations in water supply flow, and other hardware deviations.

[0003] Based on the above-mentioned technical problems in the water heating of the toilet, there is no relevant solution; therefore, it is urgent to find an effective solution to solve the above-mentioned problems
