Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Such as figure 1 As shown, the control method of the electric kettle of the present invention includes the following steps: 1. A temperature sensor, a microprocessor and a control circuit are set in the electric kettle; Transmit the detection signal to the microprocessor; 3. The microprocessor determines the system setting value; 4. Detects the on and off status of the heating circuit, and counts the continuous heating time; Time counting; 6. Check whether the temperature sensing element at the measuring point is working normally; 7. Carry out anti-dry detection and control; 8. Judgment of heating or heat preservation request; Heat preservation control; 10. Return to the initialization state after heating or heat preservation

[0022] Such as diagram 2-1 and Figure 2-2 As shown, after power-on and initialization, the microprocessor detects...

Abstract

The present invention is control method for electrically heating kettle, and aims the technological problem of connecting various control processes for the precise control of the kettle operation. The control method includes the following steps: for the microprocessor to detect the temperature in the kettle and determine the system setting values after power-on initialization; to detect the on-off state of the heating circuit; to judge the heat maintaining state; to detect water and avoid no-water heating; to judge heating and heat maintaining requirement; and to send heating or heat maintaining signal to the control circuit for heating or heat maintaining control. Compared with available technology, the present invention features the precise microprocessor control of the whole kettle heating process.

Description

technical field [0001] The invention relates to a control method of an electric kettle. Background technique [0002] The electric kettle brings convenience to people's life and work. The control method of the electric kettle in the prior art adopts a simple control method for boiling water, heat preservation and preventing dry heating.
