Water level detection and heating control system, water level detection and heating control method and electric kettle

Abstract

The invention relates to a high-precision and sensitive-response water level detection and heating control system, a water level detection and heating control method and an electric kettle. The waterlevel detection and heating control system comprises a heating device for heating water, a temperature detection device for detecting the temperature of the heating device and generating a temperaturesignal, and an MCU controller for controlling the heating device to heat. The MCU controller receives the temperature signal of the temperature detection device and generates a test temperature curve; and the MCU controller controls the heating device to heat according to the test temperature curve. According to the water level detection and heating control method of an electric kettle, whether the water amount in the kettle is lower than the water amount of the lowest water level or not is judged by testing the temperature curve of the heating device during heating, so that accurate controlover heating of the heating device is realized; the electric kettle is prevented from continuing to heat under the condition that the water amount is too small or too low, so that damages to the electric kettle are avoided, the service life of the electric kettle is prolonged, and accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a water level detection and heating control system, a water level detection and heating control method, and an electric kettle. Background technique [0002] Electric kettles are often equipped with electrical appliances for boiling water in households, and electric kettles are prone to human error during use, resulting in dry heating of the electric kettle or low heating water level, which makes the electric kettle easy to be damaged, and there is no water in the electric kettle Or heating when the water level is too low will also bring certain safety hazards. Therefore, in order to avoid the above-mentioned safety problems, existing electric kettles are generally provided with a water level sensor for testing the water level in the kettle. By monitoring the water level, it is ensured that the water level in the electric kettle is above the minimum water level befo...

Problems solved by technology

However, sometimes the plane on which the electric kettle is placed is inclined, which causes the water level in the electric kettle to also tilt relative to the electric kettle, resulting in errors in the detection method of the traditional wat
