Temperature-adjustable intelligent heater and control method therefor

Abstract

The invention discloses a temperature-adjustable intelligent heater. The temperature-adjustable intelligent heater comprises a man-machine interface module, a temperature measurement module, a control module and an output power control module, wherein the man-machine interface module is used for setting constant temperature and displaying water temperature; the temperature measurement module is used for measuring the water temperature and sending temperature data to the control module; the control module is used for receiving the temperature data of the temperature control module, performing variable parameter PID computation to get heating power PWM data and sending the heating power PWM data to the output power control module; the output power control module is used for heating water and controlling the water temperature. The temperature-adjustable intelligent heater adopts the variable parameter PID computation; according to the heating time of different temperature control heating elements, the water temperature is precisely controlled at any temperature between room temperature and a boiling temperature, and the temperature deviation is controlled within 1.5 DEG C, and the heater is fast in heating and warming and precise in temperature control, so that thermal overshoot during the heating process is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of heaters in household appliances, and in particular relates to a temperature-adjustable intelligent heater and a control method thereof. Background technique [0002] As the most commonly used household appliance, the electric kettle has a wide range of applications, and can be used for brewing infant formula milk powder and making tea at home. At present, widely used electric kettles mainly use power heating tubes to heat the water temperature, and use temperature-sensitive switches to automatically cut off the power, so as to control the water temperature to meet the needs of different water temperatures in our household life fields, such as: 40 degrees for juice brewing, 50 degrees and 60 degrees are used for brewing infant formula milk powder, 70 degrees are used for brewing coffee, 90 degrees are used for making tea, etc. As a substitute for breast milk, formula milk powder has strict requirements on...
