Electrothermic boiled water pot intelligent control circuit with multiple collecting functions

Abstract

An electrothermal water boiling pot intelligent control circuit with multiple selection functions is characterized in that: a pressure switch is connected with an input end of a single chip microcomputer and arranged at the bottom of a container; the input end of the single chip microcomputer is connected respectively with a soft-touch button, an infrared remote control receiver, a detecting circuit for the potential difference between a zero line and a ground wire, a detecting circuit for the current difference between a live wire and the zero line, an A / D temperature control circuit and twosets of soft-touch switches; an output end of the single chip microcomputer is connected respectively with an LCD, an LED and a triode switching circuit controlling the connection and disconnection of a live wire and a ground wire; the detecting circuit for the potential difference between a zero line and a ground wire connected across the ground wire and a zero line is formed by connecting a transformer, a switching tube, a Darlington tube and an operational amplifier progressively with a monostable circuit, so as to be selected and used. The intelligent control circuit has the advantage of effectively preventing the occurrence of dry heating and other accidents and using line control or remote control to set temperature, temperature display and temperature control function, so as to bring convenience to users needing the water at different temperature. As an electrothermal water boiling pot is provided with an electric shock prevention device, thereby bringing users with safe electricity using environment.

Description

technical field [0001] The invention relates to an intelligent control circuit of an electric heating water boiler, in particular to an intelligent control circuit of an electric heating boiling water boiler with multiple selection functions. Background technique [0002] Before the application date of the present invention, the electric heating water boiler had the following defects: the electric heating water boiler required that the electric heating tube must have water in the container when heating, and dry boiling was strictly prohibited. The electric heating tube of the electric heating kettle in the prior art does not control the power supply, and the power can be turned on regardless of whether there is water in the container. However, when the container is dry, the electric heating tube is turned on for heating, which may easily cause accidents such as dry burning. The electric heating kettle of the prior art does not use wire control or remote control to set the te...

AI Technical Summary

Problems solved by technology

The electric heating tube of the electric heating water boiler in the prior art does not control the power supply, regardless of whether there is water in the container, the power can be turned on, but in the case of no water in the container, turning on the electric heating tube for heating may easily cause accidents such as dry burning

The electric boiling water boiler in the prior art does not use wire control or remote control to set the temperature and has no temperature display and control functions, which brings inconvenience to users who need different water temperatures

The electric boiling water kettle in the prior art does not have an anti-electricity device, which brings unsafe factors for users to use electricity
