Heating control method of electric kettle and heating control device applying the method

Abstract

The invention discloses a heating control method of an electric kettle and a heating control device applying the method. The heating control method includes a water temperature and water volume detection step and a heating control step, through the heating control step, the electric kettle is controlled to perform intermittent heating on a water body that is heated in the cycling way of ''heating within heating intermission heating time, heating pause, heating within recalculated heating intermission heating time, and heating pause'', at each finish moment of heating intermission heating time, the water body that is heated does not reach a target water temperature, and in a period of a heating pause, afterheat released by the electric kettle is utilized to continue to heat the water body that is heated till the water temperature of the water body that is heated reaches the target water temperature, thereby greatly lowering the amplitude of the water temperature of the water body that is heated exceeding the target water temperature due to the afterheat released by the electric kettle, enabling the water body that is heated to be more accurately heated to the target water temperature, and improving heating precision of electrical heating of the kettle.

Description

technical field [0001] The invention relates to a heating control method for an electric kettle, and also relates to a heating control device for the electric kettle using the method. Background technique [0002] At present, the heating control of electric kettles is mainly divided into two methods: mechanical control and electronic temperature control. The mechanical temperature control method is to use the steam-inductive bimetal to detect the high-temperature steam generated by the boiling of water, and then to cut off the heating power supply to realize the function of turning on and off the water. The electronic temperature control method is that the controller uses the temperature sensor to detect the water temperature in the pot, and after calculation, controls the on and off of the heating element to achieve temperature control. The mechanical temperature control method can only realize a single boiling function, while the electronic temperature control method can ...
