Abstract

The invention discloses a method for water boiling of an electric kettle, and particularly relates to a control method suitable for water boiling in areas of different altitudes. The method comprisesthe following steps: a control circuit is used for controlling the power supply of a power supply circuit for an electric heating unit which emits heat to a kettle body; a temperature probe of the control circuit is used for detecting the current temperature of water in the kettle body; and in the event that the current temperature measured by the temperature probe does not lower during a certainperiod and maintains constant for a plurality of measuring times, or the current temperature measured by the temperature probe does not change for a plurality of measuring times in succession, the control circuit cuts off the power supply of the power supply circuit for the electric heating unit and withdraws. The method solves the trouble that the temperature of water boiling in different areas needs to be measured one by one and requires setting of the circuit; and simultaneously, the method also prevents the interference of the external world and can eliminate 'false boiling' phenomenon caused by constant temperature during a certain period during heating process, thereby being capable of improving the correctness of boiling control.
本发明公开了一种电煮水壶煮水的方法,尤指一种适合于不同海拔地区水沸腾的控制方法。包括由控制电路控制供电电路向电发热体供电,由电发热体向壶体发出热量;由控制电路的温度探头探测壶体内水的当前温度;若在一定时间内,温度探头测得的当前温度不再下降,且有若干次维持不变,或者温度探头测得的当前温度出现若干次连续不变,则控制电路切断供电电路停止向电发热体供电并退出。解决了对各个地方水沸腾的温度需要逐个测量并在电路中予以设定的麻烦,同时,发明还具有防止外界干扰的作用,能够排除在加热过程中可能出现的某一时刻温度不变所带来的“假沸腾”现象,从而能够提高沸腾控制的准确性。
