Intelligent control device and method for electric kettle

Abstract

The invention discloses an intelligent control device and method for an electric kettle. The control device comprises an MCU (Microprogrammed Control Unit), a temperature signal acquisition circuit, an A/D conversion circuit, a key circuit, a heating control module, a display circuit, an alarm module and a wireless communication module for being connected with a mobile Internet through a smart mobile phone, wherein the heating control module and the wireless communication module are respectively connected with the MCU; the output end of the key circuit is connected with the first input end of the MCU, the output end of the temperature signal acquisition circuit is connected with the second input end of the MCU through the A/D conversion circuit, the first output end of the MCU is connected with the alarm module, and the second output end of the MCU is connected with the display circuit. The work of the electric kettle can be remotely controlled through the smart mobile phone, the loaded frequent separating operation of a contact switch is not required, the reliability of the electric kettle is ensured, and the service life of the electric kettle is prolonged. The intelligent control device is simple in structure and low in production cost and can be widely applied to the control field of the electric kettle.

Description

technical field [0001] The invention relates to the control field of electric kettles, in particular to an intelligent control device and a control method for electric kettles. Background technique [0002] Electric kettle is a kind of household water heating appliance, which has functions such as convenient use and quick water heating, and has been widely used in people's daily life. In the prior art, the control of electric kettles is mostly limited to local control, and is controlled by conventional on / off control or bimetal temperature controller, which belongs to the control method of breaking load frequently with passive contact load. The method will have a greater impact on the service life of the electric kettle, resulting in greatly reduced reliability of the electric kettle, and the control means is simple and the function is single, and it is impossible to realize remote control away from the scene where the electric kettle is heated. In addition, although with t...

In the prior art, the control of electric kettles is mostly limited to local control, and is controlled by conventional on / off control or bimetal temperature controller, which belongs to the control method of breaking load frequently with passive contact load. The method will have a great impact on the service life of the electric kettle, which will greatly reduce the reliability of the electric kettle, and the control method is simple and the function is single, and it is impossible to realize the remote control away from the scene of the electric kettle boiling water

In addition, although with the development of the Internet of Things, household appliances are also tending to be intelligent, but electric kettles are small household appliances that are very sensitive to cost. The cost of intelligent control solutions under the embedded ARM architecture in the current technology is generally relatively high, which is not suitable Promote application in electric kettle
