Technical Field

The invention mainly relates to the field of electric kettles, in particular to an electric kettle temperature control method and an electric kettle.

Background

When an electric kettle sold in the market is heated to be close to the boiling point of water, if full-power heating is continuously kept, boiled water is in a full boiling state, and the boiled water is easy to splash from positions such as a kettle nozzle, a kettle cover edge, a ventilation opening and the like, so that a user is scalded, desktop articles are damaged, and even short circuit and other dangers are caused. In order to solve the characters of boiled water splashing, the current common scheme for solving the problem is as follows:

1. a temperature sensor is added into the kettle, and the power is reduced in advance or the kettle is heated intermittently before the water temperature rises to the standard boiling point, so that violent splashing is avoided when the water temperature reaches the boiling point. However, the boiling points of different altitude areas are different, the boiling point of the high altitude area is lower, and the boiling starts before the standard boiling point is reached, so that the power is not reduced or the heating is interrupted.

2. The nominal use capacity of the kettle is reduced, and space is reserved for boiling splashing. But the water quantity for one-time boiling is less, and the space in the kettle is wasted.
