Heating control method of electric kettle

Abstract

The invention relates to a heating control method of an electric kettle and an electric kettle for realizing the heating control method. By judging whether water is boiled according to whether time increment delta t corresponding to a raised unit value delta T of water temperature reaches the limit time increment delta t0 preset in a memory cell when water is heated for the first time, whether water is boiled can be accurately judged. Simultaneously, the invention also stores boiling temperature Tf detected during the boiling last time in the memory cell, as long as the real-time water temperature T reaches Tf when boiling next time, water is judged to be boiled, and the long-time judgment of water boiling is not required to be repeated, therefore, the boiling time is effectively saved. The method and the electric kettle can be used in areas with various sea level elevations, not only can accurately judge whether water is boiled to avoid potential safety hazards, such as heating without water, but also has the advantages of energy conservation and high temperature-controlling precision.

Description

technical field [0001] The invention relates to a heating control method for an electric kettle, in particular to a heating control method for an electronic temperature-controlled kettle used in high-altitude areas. Background technique [0002] At present, there are two common temperature control methods for electric kettles, namely mechanical temperature control method and electronic temperature control method. The mechanical temperature control method is to install a mechanical thermostat in the electric kettle. The steam-inductive bimetal sheet in the thermostat detects the high-temperature steam in the electric kettle through the steam connection tube and then acts, and cuts off the heating circuit through the mechanical connection mechanism. , realize the function of turning on the water and turning off the power. The structure of the mechanical thermostat is complicated, and it is very difficult to manufacture and assemble. At the same time, because the sensitivity a...

Problems solved by technology

[0004] One of the purposes of the present invention is to propose a heating control method for an electric kettle to overcome the problems of the electronic temperature-controlled electric kettle in the high altitude area that the water is boiling but the power is not cut off and the "secondary boiling" is easy. inadequacy of misjudgment
