Abstract

The invention provides a gravity sensor kettle comprising a kettle and a built-in function module arranged in the kettle; the built-in function module comprises a human body detection module, a gravity detection module and a relay module, a 8051 chip, a 8255 chip, a heating circuit and an alarm circuit; the input end of the 8051 chip is respectively electrically connected with the gravity detection module and the human body detection module; the gravity detection module is arranged on the top surface of a kettle pedestal; the output end of the 8051 chip is respectively electrically connected with the 8255 chip, the relay module and the alarm circuit; a normally open contact in the relay module is connected with the heating circuit; a temperature detection circuit is connected with the 8051chip via an A / D converter. The gravity sensor kettle can solve the problems that an existing kettle can only be controlled by a single mode; the gravity sensor kettle can automatically heat via humanbody sensing, thus greatly facilitating usage for users; the kettle can be heated only when the water quantity is sufficient; an empty kettle misconnection human body detection module is placed, thuspreventing dangerous heating.

Description

technical field [0001] The invention relates to a heating kettle, in particular to a gravity induction kettle. Background technique [0002] For conventional electric kettles, as long as the power is turned on, heating starts until the water boils to generate an audible alarm through steam. This design has the following disadvantages: [0003] 1. If there is no water in the kettle, it will continue to heat when the power is turned on by mistake, which may easily cause accidents. [0004] 2. When it only needs to be heated to a certain temperature below the boiling point, the sound alarm signal cannot be given in time. [0005] 3. It cannot stop working automatically when the water is heated and boiled. [0006] Aiming at the above deficiencies, the present invention adopts MC-51 single-chip microcomputer as the control chip, manages the operation situation of the whole electric kettle, and constitutes a closed-loop control system. Compared with the conventional kettle, i...
